Organic farmers use biological fertilizer inputs and management practices such as cover cropping and crop rotation to improve soil quality and build organic soil matter. In terms of soil texture, those made up of smaller particle sizes, such as in the case of silt and clay, have larger surface area. Organic matter is quite possibly the most important aspect of healthy soil. Compost helps retain moisture in the soil, provides crucial, slow release nutrients to crops and can lead to long-term yield increases. In the long term, rotation to sod and reduced tillage are known to help. Dry matter is an indicator of the amount of nutrients that are available to the animal in a particular feed. This book represents a current look at what we know about organic farming practices and systems, primarily from the United States perspective. The nutrient release occurs predominantly in the spring and summer, so summer crops benefit more from organic-matter mineralization than winter crops. Each percent of organic matter in the soil releases 20 to 30 pounds of nitrogen, 4.5 to 6.6 pounds of P 2 O 5, and 2 to 3 pounds of sulfur per year. Long-term experiments since 1843 at Rothamsted provide the longest data sets on the effect of soil, crop, manuring, and management on changes in soil organic matter … Sources of organic matter include compost, manure and crop residues.

Farm animals manure (cow, pig) is a good option here. Improving soil quality is an important consideration for every producer, not only to maintain yield, but to build resilience to the potential impacts of climate change, such as heavy downpours and extreme weather variability. First of all manure must be added for nitrogen, which is a vital component of fertile soil. That includes plant and animal materials, soil microorganisms and products of these organisms and the decomposition process. Why is organic matter important for crop production? Soils rich in organic matter hold more air and water and produce higher yields than soils low in organic matter. 27-40. Soil carbon management is an important strategy for improving soil quality, increasing crop yields, and reducing soil loss.
