Taking care of the environment is something every person in the world can contribute to. Maybe you turn off the water when you brush your teeth or carpool with friends to work. Did you know that farmers also care about the environment? Farmers want to protect the environment so they can continue to feed the world.
Here are just a few things that farmers do to protect the earth we all live on:
- Cover Crops. Have you ever driven by a field in the dead of winter and wondered why something was growing there? A cover crop is planted in a field during winter when other types of plants can’t grow. The reason farmers plant cover crops is to reduce the risk of soil erosion, or the wearing away of the soil. Some common examples of cover crops are crimson clover and radishes. Soil erosion causes many problems such as poor drainage that could lead to water pollution. The cover crop helps eliminate soil erosion since the root of the plant is holding the soil in place. When wind and rain come along, the soil will not wash away. Cover crops also help keep organic matter in the soil, which increases soil health. Through this practice, farmers are ensuring the health of their soil, while also protecting the environment.
- No-Till. Farmers prepare for the planting season through tilling the soil. Tilling is a way of preparing the soil through digging, stirring, and overturning. On the other hand, no-till is a way of growing crops from year to year without disturbing the soil through tillage. The soil in the field is not disrupted and old corn stalks or leaves act as the “cover” to the soil. Because the farmers leave the soil intact, it is less likely to be washed away by water or blown away by the wind which would cause soil erosion. Farmers want to protect the soil so it can continue to be used in the future.
- Help Reduce Runoff.
Agricultural runoff is water that leaves farm fields because of rain or melted snow. When the runoff moves, it can pick up pollutants, such as chemicals or fertilizers, which can then deposit into ponds, lakes, and sources of drinking water. Farmers can plant riparian buffers, which are vegetated areas that help prevent runoff into water sources.There are also programs in place to help protect water sources from agricultural runoff. The Mississippi River Basin Healthy Watersheds Initiative (MRBI) is one of those programs. The goal of MRBI is to work with farmers to implement conservation practices that help avoid and control runoff from fields, specifically into the Mississippi River. Farmers put a lot of effort into protecting the water that everyone drinks.
