Landowners can lease farmland for energy production, such as for oil exploration or wind turbines. For example, households that own the oil and gas rights for their property or for land in other States may lease these rights to an energy company. In 2014, the majority of income from royalties or leases associated with energy production was earned from selling or leasing these rights. In Oklahoma, Utah, and Kansas, about 20 percent of farms received income from energy production. In States with active development of shale oil or gas, about 12 percent of farms received an average income of $65,781 from energy production—compared with 6 percent and $56,162 for the entire United States. Average payments were highest in North Dakota ($157,000) and Pennsylvania ($154,000), mainly due to oil and gas drilling in the Bakken and Marcellus shales. Total payments from energy companies to farms reached $2.9 billion in 2014, up from $2.3 billion in 2011. This chart appears in the November 2016 Amber Waves article, Share of Farm Businesses Receiving Lease and Royalty Income From Energy Production Varies Across Regions.

Precision agriculture delivers localized crop production management through a number of different technologies. One of them, variable rate technology (VRT), adapts machinery and field operation equipment—such as sprayers and seeders—to automatically control input flow rates. Farmers can even use VRT to plant different types of seeds at different locations with a single pass of the tractor. However, installing and maintaining equipment with VRT capabilities comes at a relatively high cost. Empirical estimates showed that, in 2010, VRT still improved profits on corn farms by about 1 percent. Between 2010 and 2013, VRT adoption also reached about 20 percent of planted acres in corn, soybean, rice, and peanut production. This chart appears in the ERS report Farm Profits and Adoption of Precision Agriculture, released October 18, 2016.

Genetically engineered (GE), herbicide-tolerant (HT) varieties of crops were first developed in 1996 to survive herbicides that previously would have destroyed the crop along with the targeted weeds. The success of major GE crops—more than 90 percent of U.S. corn, soybean and cotton use GE seeds with HT or insect-resistant traits—enabled the commercialization of HT canola in 1998 and of HT alfalfa and sugarbeets in 2005. Two of these crops have seen rapid adoption in recent years: about 95 percent of U.S. canola and over 99 percent of sugarbeet acres planted in 2013 had HT traits. By comparison, only 13 percent of alfalfa acres harvested had HT traits that year. This slower adoption rate is expected—alfalfa is a perennial crop and only about one-seventh of the alfalfa acreage is newly seeded each year. This chart is based on the ERS report The Adoption of Genetically Engineered Alfalfa, Canola, and Sugarbeets in the United States, released November 2016.

Since the early 2000s, farms have increased renewable energy production with technologies like solar panels, wind turbines, and methane digesters. From 2007 to 2012, the number of farms generating on-farm renewable energy more than doubled to nearly 58,000—or 2.7 percent of U.S. farms. This does not include the roughly 16,600 farms that leased wind rights to others or that produced ethanol and biodiesel on the farm. Adoption of on-farm renewable energy systems varies across the country but it is concentrated in the Western United States, Illinois, and New England. In these regions, about two in five farm businesses produce renewable energy in some counties. The Southeastern States, which have fewer subsidies and programs supporting renewable power, had low adoption rates. This chart appears in the August 2016 ERS report Trends in U.S. Agriculture’s Consumption and Production of Energy: Renewable Power, Shale Energy, and Cellulosic Biomass.

Farmers can receive Federal financial assistance for implementing a wide range of conservation practices from the Natural Resources Conservation Service’s Environmental Quality Incentives Program (EQIP). Adopting no-till and planting cover crops are two common agricultural practices that can improve soil health. Farmers receiving payments for no-till agree to plant crops without using any sort of plow to turn residue from the prior crop into the soil. Those receiving payments for cover crops plant certain crops (such as clover, field peas, and annual ryegrass) or a mixture of crops to maintain cover and add organic matter. Cover crops are usually grown over the winter, between plantings of commodity crops. From 2005 to 2013, USDA funding for cover crops in EQIP increased ten-fold—from about $5 million to more than $50 million in nominal terms. Over this same period, funding for no-till adoption declined. This shift in focus can be attributed to a variety of factors, such as increasing adoption of no-till by farmers even without payment and improving availability of cover crop seeds and educational materials. This chart appears in the September 2016 Amber Waves feature, “An Economic Perspective on Soil Health.”

Guidance systems use global positioning system (GPS) coordinates to automatically steer farm equipment like combines, tractors, and self-propelled sprayers. Guidance systems help reduce operator fatigue and pinpoint precise field locations, within a few inches. Freed from steering, operators can access timely coordinates from a screen, monitor other equipment systems more closely, and correct problems more quickly. Guidance systems also reduce costs by improving the precision of sprays and the seeding of field crop rows. Between 2010 and 2013, these systems were adopted on 45 to 55 percent of planted acres for several major crops, including rice, peanuts, and corn. Once adopted for a particular crop, the use of guidance systems tends to be rapidly adopted by other crop farmers. The ease-of-use and functionality of these systems has also increased along with adoption rates. This chart appears in the ERS report Farm Profits and Adoption of Precision Agriculture , released October 18, 2016.

Farms rely on electricity to power many essential systems, including irrigation, ventilation, and heating and cooling. Sometimes, due to seasonal demand, farms pay high prices for electricity. How much farms spend on electricity as a percentage of total expenses in a given year varies with farm size and principal commodity. In 2014, the highest share of electricity expenses by commodity were on farms concentrating on the production of peanuts (5.5 percent). By farm size, small poultry producers had the highest share of electricity expenses, 12.8 percent—about 8 times more than large poultry producers. With the exception of peanut producers, large farms had the lowest shares of electricity expenditure among all farm sizes. Large peanut producers likely had a higher share of electricity expenses compared to small producers because irrigation and on-farm drying of harvested peanuts were more economical on large farms. This chart appears in the August 2016 ERS report Trends in U.S. Agriculture’s Consumption and Production of Energy: Renewable Power, Shale Energy, and Cellulosic Biomass.

In 2010, to help meet water quality goals, the U.S. Environmental Protection Agency (EPA) adopted a limit on the amount of pollutants that the Chesapeake Bay can receive. Nitrogen and phosphorus, in particular, can lead to adverse effects on public health, recreation, and ecosystems when present in excess amounts. The EPA estimates that applications of manure contribute 15 percent of nitrogen and 37 percent of phosphorus loadings to the Bay. Furthermore, ERS estimates that animal feeding operations (AFOs), which raise animals in confinement, account for 88 percent of manure nitrogen and 84 percent of manure phosphorus generation in that watershed. ERS also estimates that about a third of nitrogen and half of phosphorus produced at AFOs can be recovered for later use. That adds to about 234 million pounds of nitrogen and 106 million pounds of phosphorus recovered. These nutrients can then be redistributed regionally to fertilize agricultural land, thereby lessening nutrient run-off problems in the Bay. The remaining nutrients cannot be recovered. Both nitrogen and phosphorus may be lost during collection, storage, and transportation; nitrogen may also volatize into the atmosphere. This chart is based on the ERS report Comparing Participation in Nutrient Trading by Livestock Operations to Crop Producers in the Chesapeake Bay Watershed, released in September 2016.

Genetically engineered (GE) seeds are widely used in U.S. field crop production. Herbicide-tolerant (HT) crops were developed to survive the application of certain herbicides that previously would have destroyed the crop along with the targeted weeds. Insect-resistant crops contain a gene from the soil bacterium Bacillus thuringiensis (Bt) that produces a protein that is toxic to specific insects. Seeds that have both herbicide-tolerant and insect-resistant traits are referred to as “stacked.” Recent data show that the adoption of stacked corn varieties has increased from 15 percent of U.S. corn acres in 2006 to 76 percent in 2016. Adoption rates for stacked cotton varieties have also grown, from 39 percent in 2006 to 80 percent in 2016. Generally, many different GE traits—each aimed at a specific herbicide or insect—can be stacked; varieties with three or four GE traits are now common. Research suggests that stacked corn seeds have higher yields than conventional seeds or seeds with only one GE trait. This chart is based on data found in the ERS data product, Adoption of Genetically Engineered Crops in the U.S., updated July 2016.

Farms consume energy directly in the form of gasoline, diesel, electricity, and natural gas; and indirectly in energy-intensive inputs such as fertilizer and pesticides. Farm businesses—operations with annual gross cash farm income of over $350,000 or smaller operations where farming is reported as the operator’s primary occupation—vary in mix and intensity of direct and indirect energy use. In 2014, farm businesses concentrating on rice, peanut, wheat, and cotton production spent 43-49 percent of their total cash expenses on direct and indirect energy inputs, more than any other crop and livestock producers. Fertilizer and pesticides, which are indirect energy uses because they require large amounts of energy to manufacture, account for the greatest share of energy expenses among farm businesses primarily producing crops. For livestock producers, feed is also an important indirect energy expense but, in this analysis, these costs are accounted for in the crop budgets. Fertilizer expenses accounted for 18-22 percent of total cash expenses for farm businesses concentrating in wheat, corn, and other cash-grain production, and 14-17 percent for farm businesses primarily producing other field crops. Cotton and rice production were associated with relatively high shares of direct energy inputs: fuel is used to apply chemicals and electricity powers irrigation equipment. Peanut producers, which use electricity for irrigation and on-farm drying of harvested peanuts, had the highest share of electricity use at 6 percent, followed by farm businesses concentrating on poultry and cotton at 4 percent. This chart is found in the ERS report, Trends in U.S. Agriculture’s Consumption and Production of Energy: Renewable Power, Shale Energy, and Cellulosic Biomass, released on August 11, 2016.

U.S. soybeans, cotton and corn farmers have nearly universally adopted genetically engineered (GE) seeds in recent years, despite their typically higher prices. Herbicide-tolerant (HT) crops, developed to survive the application of specific herbicides that previously would have destroyed the crop along with the targeted weeds, provide farmers with a broader variety of options for weed control. Insect-resistant crops (Bt) contain a gene from the soil bacterium Bacillus thuringiensis that produces a protein toxic to specific insects, protecting the plant over its entire life. “Stacked” seed varieties carry both HT and Bt traits, and now account for a large majority of GE corn and cotton seeds. In 2016, adoption of GE varieties, including those with herbicide tolerance, insect resistance, or stacked traits, accounted for 94 percent of soybean acreage (soybeans have only HT varieties), 93 percent of cotton acreage, and 92 percent of corn acreage planted in the United States. This chart is found in the ERS data product, Adoption of Genetically Engineered Crops in the U.S., updated July 2016.

Most labor on small U.S. dairy farms is provided by the operator and the operator’s family, whereas large dairy farms, while usually still family-owned and operated, rely extensively on hired labor. Labor productivity—output of milk per hour of labor—is much higher on larger dairy farms, with the largest (farms with milking herds of at least 2,000 cows) realizing 10 hundredweight (cwt) per hour of labor, compared to 2-4 cwt per hour on farms with herds of 50-500 head. Large farms operate differently than small dairy farms, as their size allows them to apply practices and technologies that result in higher milk yields and labor productivity. For example, farms with at least 500 cows are much more likely to milk three times a day, while smaller farms typically milk twice a day. Thrice-daily milking raises per-cow milk yields, allows farms to offer more work and higher pay to their hired labor, and creates more intensive use of milking equipment. Greater labor productivity is one source of the cost advantages accruing to larger dairy operations. This chart is based on data found in the ERS report, Changing Structure, Financial Risks, and Government Policy for the U.S. Dairy Industry, March 2016.

For weed control, U.S. corn and soybean farmers rely on chemical herbicides which were applied to more than 95 percent of U.S. corn acres in 2010 and soybean acres in 2012. Over the course of the last two decades, U.S. corn and soybean farmers have increased their use of glyphosate (the active ingredient in herbicide products such as Roundup) and decreased their use of herbicide products containing other active ingredients. This shift contributed to the development of over 14 glyphosate-resistant weed species in U.S. crop production areas. Glyphosate resistance management practices (RMPs) include herbicide rotation, tillage, scouting for weeds, and other forms of weed control. In some cases, ERS found that usage rates for RMPs increased from 1996 to 2012. In other cases, RMP use dropped from 1996 to 2005/06 but increased as information about glyphosate-resistant weeds spread. For example, herbicides other than glyphosate were applied on 93 percent of planted soybean acres in 1996, 29 percent in 2006, and then 56 percent in 2012. This chart is found in the April 2016 Amber Waves finding, “U.S. Corn and Soybean Farmers Apply a Wide Variety of Glyphosate Resistance Management Practices.”

Efficient nitrogen fertilizer applications closely coincide with plant needs to reduce the likelihood that nutrients are lost to the environment before they can be taken up by the crop. Fall nitrogen application occurs during the fall months before the crop is planted, spring application occurs in the spring months (before planting for spring-planted crops), and after-planting application occurs while the crop is growing. The most appropriate timing of nitrogen applications depends on the nutrient needs of the crop being grown. In general, applying nitrogen in the fall for a spring-planted crop leaves nitrogen vulnerable to runoff over a long period of time. Applying nitrogen after the crop is already growing, when nitrogen needs are highest, generally minimizes vulnerability to runoff and leaching. Cotton farmers applied a majority of nitrogen—59 percent—after planting. Winter wheat producers applied 45 percent of nitrogen after planting. Corn farmers applied 22 percent of nitrogen after planting, while spring wheat farmers applied 5 percent after planting. Farmers applied a significant share of nitrogen in the fall for corn (20 percent) and spring wheat (21 percent). Fall nitrogen application is high for winter wheat because it is planted in the fall. This chart is found in the ERS report, Conservation-Practice Adoption Rates Vary Widely by Crop and Region, December 2015.

While some small U.S. dairy farms earn profits and some large farms incur losses, financial performance in the dairy sector, on average, is linked to herd size. Data from 2010 (the latest available for dairy farms by herd size) show that a majority of dairy farms with milking herds of at least 1,000 cows generate gross returns that exceed total costs, while most small and mid-size dairy farms do not earn enough to cover total costs. Total costs include annualized capital recovery as well as the cost of unpaid family labor (measured as what the farm family could earn off the farm), in addition to cash operating expenses. Many more small and mid-sized farms are able to cover total costs, except for costs associated with capital recovery. Farms can operate in this way for years, covering operating expenses and providing a reasonable income for a farm family, until the expense of maintaining aging equipment and structures begins to erode the incomes that a family can earn from the farm. At that point, many families may decide to close the farm. Some—particularly those where a younger generation intends to continue the business—may seek financing to expand the dairy herd and realize lower costs through scale economies. This chart is found in the ERS report,

Livestock farmers use antibiotics to treat, control, and prevent disease, and also for production purposes, such as increasing growth and feed efficiency. A new U.S. Food and Drug Administration initiative seeks to eliminate the use of medically important antibiotics for production purposes. In the 2011 Agricultural Resource Management Survey (ARMS) on broilers (the most recent year available), producers were asked whether they raised their broilers without antibiotics in their feed or water unless the birds were sick, which implies not using antibiotics for growth promotion or disease prevention. In 2011, growers reported that about half of birds (48 percent) were only given antibiotics for disease treatment. This response also accounts for 48 percent of operations and 48 percent of production (by live weight). Approximately a third (32 percent) of operators stated that they did not know if they provided antibiotics via feed or water for purposes other than disease treatment; this means the proportion of reporting operations that only supplied antibiotics for disease-treatment purposes could be as high as 80 percent. Contracted growers (accounting for 96 percent of broiler production) may not know if antibiotics are in the feed provided by the company for whom they raise broilers. These statistics suggest that in 2011, between 20 and 52 percent of birds were given antibiotics for reasons other than disease treatment. This chart is found in the Amber Waves feature, “Restrictions on Antibiotic Use for Production Purposes in U.S. Livestock Industries Likely To Have Small Effects on Prices and Quantities,” November 2015.

Two decades ago, most milk came from farms with fewer than 150 cows, on which a farm family handled milking, herd management, and crop production for feed. Today, while the United States still has many herds of 50 to 100 cows, most cows and milk production have moved to much larger farms, which are usually still owned and operated by families, but rely on hired labor for most farm tasks. Farms with milking herds of at least 1,000 cows accounted for nearly half of all cows in 2012, up from 10 percent of all cows in 1992. Producers continued to increase herd size in that period; there were 17 farms with herds of 4,000 or more cows in 1992, compared to 95 farms in 2002 and 234 in 2012. Costs are an important reason behind the shift, as production costs appear to be substantially lower, on average, on larger farms. The data underlying this chart are available in the ERS report, Changing Structure, Financial Risks, and Government Policy for the U.S. Dairy Industry, March 2016.

Cover crops are thought to play a role in improving soil health by keeping the soil “covered” when an economic crop is not growing. Cover crops reduce soil erosion, trap nitrogen and other nutrients, increase biomass, reduce weeds, loosen soil to reduce compaction, and improve water infiltration to store more rainfall. The 2010-11 Agricultural Resource Management Survey was the first USDA survey to ask respondents to report cover crop use (findings from the 2012 Agricultural Census—the most recent available—are similar). Approximately 4 percent of farmers adopted cover crops on some portion of their fields, accounting for 1.7 percent of total U.S. cropland (6.8 million acres) in 2010-11. Cover crop adoption was highest in the Southern Seaboard (5.7 percent) and lowest in the Heartland and Basin and Range (0.6 percent each). This distribution is likely due to the fact that cover crops are easiest to establish in warmer areas with longer growing seasons. Limited cover crop use overall, however, suggests that the benefits of cover crop adoption are being realized on few acres. This chart is from the ERS report, Conservation-Practice Adoption Rates Vary Widely by Crop and Region, December 2015.

U.S. farmers used genetically engineered (GE) seed varieties that contain traits to tolerate herbicides used for weed control and/or to resist other pests on over 90 percent of corn acreage in 2015. To receive the price premiums associated with organic and other non-GE crops, these producers must minimize the unintended presence of GE materials in their crops. Organic and other non-GE farmers use various practices—including the use of buffer strips to minimize pesticide/pollen drift and/or delaying crop planting until after any nearby GE crops are planted—to prevent their crops from commingling with GE crops. While some field crops are mostly self-pollinating, most corn pollination results from pollen dispersal by wind and gravity. In USDA’s most recent (2010) corn survey of conventional and organic producers in top corn producing States, delayed planting was reported on two-thirds of planted organic corn acreage. While this strategy helps protect against commingling of GE and non-GE crop pollen, growers may realize lower yields from planting at a suboptimal time. This chart is found in the ERS report, Economic Issues in the Coexistence of Organic, Genetically Engineered (GE), and Non-GE Crops, February 2016.

No-till and strip-till are two of many tillage methods farmers use to plant crops. In a no-till system, farmers plant directly into the undisturbed residue of the previous crop without tillage, except for nutrient injection; in a strip-till system, only a narrow strip is tilled where row crops are planted. These tillage practices contribute to improving soil health, and reduce net greenhouse gas emissions. During 2010-11, about 23 percent of land in corn, cotton, soybeans, and wheat was on a farm where no-till/strip-till was used on every acre (full adopters). Another 33 percent of acreage in these crops was located on farms where a mix of no-till, strip-till, and other tillage practices were used on only some acres (partial adopters). In the Prairie Gateway, Northern Great Plains, and Heartland regions—which account for 72 percent of corn, soybean, wheat, and cotton acreage—more than half of these crop acres were on farms that used no-till/strip-till to some extent. Partial adopters have the equipment and expertise, at least for some crops, to use no-till/strip-till; these farmers may be well positioned to expand these practices to a larger share of cropland acreage. This chart is from the ERS report, Conservation-Practice Adoption Rates Vary Widely by Crop and Region, December 2015.
