Interpretive Summary: Adding organic matter to poor soils has become a major componenet of soil health management programs. Many of the soil¿s properties are directly related to organic matter content and quality. Adding organic matter to soil influences diverse and important biological activities. The diversity and number of free-living and plant-parasitic nematodes are altered by rotational crops, cover crops, green manures, and other sources of organic matter. Soil management programs should include the use of the proper organic materials to improve soil chemical, physical and biological parameters and to suppress plant-parasitic nematodes and soilborne pathogens. It is critical to monitor the affects of organic matter additions on activities of major and minor plant-parasitic nematodes in the production system. This paper presents a general review of information in the literature on the effects of crop rotation, cover crops, and green manures on nematodes and their damage to economic crops.

Technical Abstract: Organic matter and its replenishment has become a major componenet of soil health management programs. Many of the soil¿s physical, chemical, and biological properties are a function of organic matter content and quality. Adding organic matter to soil influences diverse and important biological activities. The diversity and number of free-living and plant-parasitic nematodes are altered by rotational crops, cover crops, green manures, and other sources of organic matter. Soil management programs should include the use of the proper organic materials to improve soil chemical, physical and biological parameters and to also suppress plant-parasitic nematodes and soilborne pathogens. It is critical to monitor the affects of organic matter additions on activities of major and minor plant-parasitic nematodes in the production system. This paper presents a general review of information in the literature on the effects of crop rotation, cover crops, and green manures on nematodes and their damage to economic crops.
