These are just a few examples of how farmers steward the land by using soil conservation practices. Farmers work hard to keep the land and soil healthy now and for future generations. They know their actions affect the environment. No one is closer to the earth than farmers and it is important to them to care for the land, water and natural resources.
1. Cover Crops
No, this isn’t when farmers put a blanket over their crops! Cover crops are plants grown to protect and enrich soil and make sure soil is healthy by putting nutrients back into it. They help slow erosion, control pests and diseases, and increases organic matter. The use of cover crops has also been shown to increase crop yields. This means a farmer can grow more food and feed more people!

2. Crop Rotation
Crop rotation is a technique of planting different crops in the same field, but during different times. This helps soil because some plants take nutrients from the soil while others add nutrients. Changing, or rotating, crops keep the land fertile because not all of the same nutrients are being used with each crop. Historians believe that that crop rotation was used as early as 6,000 B.C.!
This America’s Heartland video breaks down crop rotation.
3. Buffer Zones
With buffer zones, farmers plant strips of vegetation between fields and bodies of water such as streams and lakes. These plants help keep soil in place, keeping soil out of the water source. Buffer zones also act as a filter for water that flows from the field to the waterway. Want More?

4. No Till Fields
In tilled fields, soil is broken up to make it easier for crops to grow. Because the soil is loose it can blow away in the wind or be washed away by rain, so some farmers chose to not till their fields. This means that they do not break up the soil in their fields, keeping the soil in place when it rains and helping moisture stay in the soil.
