Place construction debris in dumpsters for safe disposal. Never dump debris into creeks or canyons. Improving soil also helps prevent pollution. Just as increasing organic matter levels in the soil can increase crop yields, it can also improve the health of the plant and the ability of the roots to hold soil in place. Increasing organic matter in the soil increases the level and activity of microorganisms that release nutrients from the organic matter for use.
Organic matter is the adhesive for holding soil particles together by increasing soil aggregation.
This makes the soil particles less susceptible to being dislodged by wind or raindrops. Last updated May 21, 2001.
