Identifying Opportunities and Planning Successful cover cropping starts with a strong crop plan and requires additional planning around cash-crop termination and no-till seeding methods. Flail mow and direct seed with a grain drill – This is the best method in a larger-scale commercial garden (1+ acre).
For example, if a fall-winter cashcrop was turned over and immediately planted to a spring crop, the summer-winter mix is a good follow up to provide an extended period of rest through the winter. You can also inter-seed winter species to a summer cashcrop. However, cold hardy cereal grains (i.e.,
But there was one crop that suffered less. “It It doesn’t take a whole lot of rain to make a good yield for the sorghum crop,” said Rendel, who plants about 1,000 acres of grain sorghum each year on his 5,000-acre farm. While he did lose some of his grain sorghum, or milo, to the drought, the loss was minimal compared to corn.
Grover established a peach orchard in 1935, and cultivated grain and raised livestock until the late 1970s. With tobacco as his principal cashcrop, Arthur needed to purchase fertilizer before December and prepare the land for planting by February or March. The delays in payment could be devastating. Im building the soil.
It works as both a cover crop and forage for the cattle, and it’s helping Bedtka build up organic matter in his soil. Corn requires lots of nitrogen, and it’s by far the most commonly used fertilizer in the United States. Southeastern Minnesota’s Olmsted County is a microcosm of agriculture’s dependence on nitrogen fertilizer.
A fertile land can be a fertile civilization The swath of land between the Euphrates and Tigris Rivers in Mesopotamia was one of the most fertile lands known to humans, as was the riparian land of the Nile River in Ancient Egypt. Excessive fertilization has polluted aquifers with nitrates.
Some farmers and researchers like those running the Wisconsin Integrated Systems Cropping Trial are developing increasingly sophisticated polyculture with two or more crop species in the same field at the same time. Rotating crops also significantly reduces pests and diseases.
One way to reduce agricultural chemicals is planting cover crops in the Fall after the cashcrop is harvested. Winter cover crops could mean using less fertilizer and herbicide in the Spring. Grain prices began to fall and crops weren’t worth what farmers put into them.
A review from earlier this year found that only a third of published studies in which researchers compared fields that were cover-cropped with those that weren’t reported significant gains in soil carbon. And a study published last month illustrated one major reason why farmers may be reluctant to plant cover crops.
It was the annual field day at The Mill , a popular Mid-Atlantic retailer of agricultural products including seeds, fertilizer, and pesticides. In fact, the two practices that dominate current markets—no-till and cover crops—require herbicides to succeed in the way they’re practiced on most commodity farms.
Along with reducing the need for synthetic fertilizers, pesticides, and herbicides, practices that build healthy soil, for example, make land more resilient to drought, flooding, wildfires, and erosion. As a result, smaller producers often face greater hurdles in adopting any practices that sit outside the mainstream.
Fertilizer, fuel, and labor costs increase every year, while prices hardly change. Linwood Scott III is a sixth-generation tobacco farmer who’s worried about the crop’s “razor-thin margin.” The tobacco side of the farm has grown from 50 acres to 150, and the farm also produces soybeans and graincrops on another 850 acres.
