Comparisons of Manure, Compost, and Commercial Fertilizers

Manures Disadvantages • Nutrients can be easily leached through the soil profile or volatilized if left on the surface • Nutrient content is highly variable • May introduce human pathogenic bacteria such as fecal coliform or E.coli • May introduce weed seeds • Weight and bulk of transporting and applying wet manures to fields

Introduction to Organic Practices

producers build soil quality by adding compost, animal manures, or green manures. As soil organisms break down these inputs, they convert nutrients into forms plants can absorb and create humus that sustains soil quality. Organic producers must not apply sewage sludge or biosolids to soil. Additionally, organic

manures, and from rice grown under flooded conditions (Mosier et al. 1998). N 2 O is generated by the microbial transformation of nitrogen in soils and manures, and is often enhanced where available nitrogen (N) exceeds plant requirements, especially under wet conditions (Oenema et al., 2005; Smith and Conen, Smith

Volatilization losses are higher for manures and urea fertilizers that are surface applied and not incorporated (by tillage or by rain) into the soil. Manure contains N in two primary forms: ammonium and organic N. If manure is incorporated within one day, 65% of the ammonium N is retained; when incorporated after
