Soils
Soil is composed of sand, silt, clay, and organic matter. Each component varies greatly from place to place. Soils are important because they hold moisture and nutrients which are needed for vegetation and crops to grow. Soil types vary in their water holding capacity and their productivity.

The Hope in Healthy Soil
8-part video series highlights many of the important principles and practices behind growing soil health in your farm field or backyard.
- Reduce Soil Erosion: Protect soil from erosion by maintaining a healthy stand of vegetation which will hold the soil in place and allow rain water to infiltrate into the soil rather than run off. Simply minimize the size and number of bare spots on your land. Protecting soils from erosion is important because grass and other vegetation need soil in order to grow productively. Wind can blow soil away and water can wash across land taking soil with it.
Water Erosion Wind Erosion - Soil Water Management: Protecting soils from erosion can also allow soils to capture more available moisture. Increase soil moisture by maintaining a larger amount of crop stalk or grass in the Fall. The extra vegetation will hold more snow, and thus keep more moisture on your property.
- Add compost to your soil: Composting is a wonderful strategy to create free and nutrient-rich soil usable in your garden and houseplants. Click here for more information.
- Test soil for nutrient and organic matter: Many nutrients and macronutrients are available in soil at various proportions. It is important to take a soil test every year to determine if additional fertilization is needed. In general, native range grasses may not need additional fertilization. Grass litter and the manure droppings during grazing will provide enough nutrients for native grasses. However, irrigated and introduced grasses will need additional nutrients. Soil test kits can be ordered from the Colorado State University Soil, Water, and Plant Testing Lab.
- Reduce Soil Compaction: Roots need to be able to grow deep into the soil. When soil is compacted roots may not be able to find the moisture or the nutrients they need to thrive. You can reduce soil compaction by minimizing traffic or grazing when the soil is wet.
