There are many ways to make farm soil more productive. One way is to use a process called double digging. This involves loosening the top layer of soil with a spade or shovel and then turning it over. The second layer is then loosened and turned over on top of the first layer. This process breaks up any large clumps of dirt, aerates the soil, and helps improve drainage.
Another way to improve farm soil is to add compost or manure. Compost is made from organic matter such as leaves, grass clippings, and kitchen scraps. It adds nutrients and moisture to the soil. Manure is also full of nutrients that can help plants grow. It also helps improve the texture of heavy clay soils.
Farmers can also use cover crops to improve their soil. Cover crops are planted in between cash crops (such as corn or soybeans). They help reduce erosion, build up organic matter, and add nitrogen to the soil. Some common cover crops include clover, alfalfa, and rye grass.
