Restoring Soil Quality

Organic Matter

Increasing organic matter content increases biological life, the number of soil pores, and soil permeability. Compost, or decomposed organic material, is a great source of organic matter. Compost improves soil structure, aeration, water retention, drainage, and nutrient quality. Keeping the organic material in existing vegetation and litter in place near streams and lakes protects water quality by capturing sediment, nutrients, and other pollutants in runoff.

Deep Tillage

Deep tillage can be performed with machinery. Always have underground utilities and other underground plumbing or wires located and marked. It is best to perform deep tillage when moisture content is about 40 percent.

Vegetation

Establishing vegetation to cover bare soil is critical. A seeded lawn with a mixture of grass seed and compost is best for new lawns. It is often less expensive and establishes faster than sod. The higher organic matter content and improved soil structure in compost-seeded lawns can retain 80 percent more rainfall resulting in less watering and fertilizer than sod lawns and less storm water runoff. Well planned and maintained vegetation will also discourage the establishment of noxious weeds.

Native Landscaping

Native plants have a tremendous root structure. This deep root structure adds organic matter to the soil and increases water infiltration. Use native landscaping strategically to manage rainfall and diversify urban landscapes.
