compost pileComposting is the time-honored practice of using natural microbial processes to break down organic materials such as grass clippings, kitchen wastes, yard and garden debris, leaves, and sometimes livestock manures to create a valuable soil amendment.

Having a compost pile cuts down on the organic waste a household contributes to the community's waste stream. Applying compost to garden soils: 

  • Increases soil organic matter.
  • Improves a soil's physical properties.
  • Helps retain and release soil moisture.
  • Supplies some nutrients essential for plant growth.

Cover croppingcover crop growing

A "cover crop" is a crop planted to protect and cover bare soil. Gardeners typically plant a cover crop to prepare a new garden plot for next spirng's planting or after harvesting a summer or early fall crop to protect the soil over winter.

Some gardeners sow certain cover crops to protect the soil between beds or rows planted to food crops.

Growers may incorporate a mature cover crop back into the soil to decompose or allow it to winter-kill to provide a light mulch for the spring crop.

Cover crops can serve many purposes They protect bare soil from erosion, reduce nutrient leaching, hold moisture in the soil, help suppress weeds, and boost soil organic matter. Some cover crops help attract beneficial insects. Leguminous cover crops (clovers, field peas, beans) fix nutrogen that becomes available to the crop planted next.
