In the Sоutheаst US, peаnut аnd cоttоn are important crops, often grown in rotation. An alternative to this traditional model is to change cotton for a different row crop and/or include perennial grasses in the rotation. Below, we describe two agroecosystems that you will have to rank according to the scorecard. System 1 This farm has several dozens of acres under the traditional rotation of cotton and peanut, with two years of cotton followed by one year of peanut. This system is irrigated using a pivot system (i.e., overhead) with a soil moisture sensor, with one sensor per pivot that allows to apply water whenever summer precipitation is too low to ensure maximum productivity. Fertilization for the cotton phase is done with synthetic fertilizers, using an N-P-K blend at planting and N fertilization as a sidedress. No fertilizers are added to the peanut, as recommended by the local extension office. They do however add a low amount of composted poultry manure from a local farmer before peanut, to replace the P exported by the crop. Tissue testing is used to verify that plants are adequately fed, although results rarely show nutrient levels that would trigger fertilization. In most cases, it would be for micronutrients, and they would apply a foliar spray as needed, combining this with a spray for pest management. These farmers use genetically-modified cotton varieties that are resistant to both herbicides and main pests, which allows to decrease the number of insecticide and fungicide sprays by more than half. They use as little herbicide as they can but need to rely on a few sprays each year, as they are strip-tilling their system and cannot cultivate weeds as efficiently during the growing season. The inclusion of a winter rye cover crops a few years ago has decreased their weed pressure, although it added an extra herbicide application – overall, it allowed them to reduce the number of overall herbicide sprays. Like other row crop farms in the area, crops are cultivated fence-to-fence, with no hedgerows or windbreak. Farmers with land bordering streams have riparian zones, but this farm doesn’t border any waterbody. The region is composed of a mosaic of similar cotton-peanut farms that dominate the landscape, along with other annual crops (e.g., watermelons), pastures, and pine plantations. These farmers are one of the most productive in the region, although the second cotton crop (coming after cotton) isn’t as productive as the first cotton crop and the peanut crop. All their products (cotton lint for textile, cotton seed for animal feed, peanut) are processed locally, and then sold to wholesale buyers that distribute them throughout the country, and sometimes internationally. Because of their high productivity and their history in the area (this land has been farmed by the same family for generations), they never had a problem getting a loan. They recently got a loan to improve their machinery, allowing for improved precision in delivering fertilizers and pesticides, with insulated cabins equipped with improved air filters. This allowed them to eliminate manual labor on the fields themselves, as all operations are now mechanized. The farmers took this opportunity to slow down and give a promotion and more responsibilities to their current employees, which have been around for several years. They haven’t had to hire new workers in years as their retention is high due to the above-average pay and conditions for the area. When they do hire, they rarely have a shortage of quality applicants to choose from. System 2 The second farm is the direct neighbor to system 1, and it has modified its cotton-peanut rotation over 10 years ago. It is now operating as a four-year rotation: grain corn, peanut, and two years of grazed bahiagrass pasture. Their multi-acre farm has several pivots, with each pivot split into four quadrants and one quadrant per stage of the rotation. Irrigation in this system is turned on based on farmer observation, although irrigation needs have decreased for row crops since including the grazed pasture. Their corn fertilization is very similar to what is used for cotton (with rates adjusted for a corn crop though), the first year of bahiagrass gets the base N-P-K fertilizer only, and they don’t fertilize the second year of bahiagrass or peanut at all. Overall, annual tissue testing confirms they are always in the sufficiency range, sometimes higher, and recent soil tests at the end of the second bahiagrass season indicated a build-up of nutrients, especially P. They use a rye cover crop for all fields during the winter, regardless of the previous crop, which provides grazing material for cattle during the winter. In the summer, cows only graze in bahiagrass plots. This farm added clover to the cover crop mix last year, and given the good results for cattle weight gain (and pretty flowers!), they will use clover in all winter cover cropping from now on. Due to unevenness of cattle grazing, trampling, feces excretion, etc., they completely till the quadrants coming out of bahiagrass with a disk, whereas the row crops are strip tilled – the first year of bahiagrass is not tilled at all. Pest management follows a similar approach as the first system, with genetically-modified corn that allows to reduce insect damage. Herbicide use is similar for the row crops and cover crop, although herbicides are not used for the second year of bahiagrass. Also, they noticed that peanut following bahiagrass experiences lower nematode pressure relative to when they used the traditional rotation. Overall, they found a reduced pest pressure since including the perennial crop in their system, which has reduced their use of pesticides, including herbicides. Being the direct neighbor to system 1, the regional land use is very similar, although they are one of only two farms in the county that have integrated perennial grasses and livestock in their row crop farm. They do have a stream that borders one end of their property, with a relatively unmanaged riparian border, but otherwise there are no other hedgerows or semi-managed ecosystems. This farm’s productivity is similar to others in the region for all crop and animal products. Crop products (corn grain and peanut) are processed locally and sold to wholesale buyers, like farmer 1, whereas their calves are sent out of state for finishing in large feeding operations in the central plains. For all of their products, once they are sold to wholesale buyers, they do not control where those products are being marketed and sold. Implementing the transition to corn and cattle grazing has required large loans, but they are finally done reimbursing them. This has delayed improvements on several aspects of the farm, which is further complexified by the addition of a third crop with different machinery requirements and an animal operation. They have started the process of getting additional credit to make these improvements, but the greater complexity and infrastructure needs of their operation and the greater volatility of beef prices relative to row crop prices in recent years has led to increased scrutiny from lenders. Ultimately, their credit approval and interest rate weren’t affected for these loans. The inclusion of cattle in their operation has increased labor demand, but they have not always been able to find people with the more elaborate skillset required to work with three distinct crops and an animal operation. Those that fit well do stay however, as their conditions are like system 1 (and above average for the area).
