Soil organic matter (SOM) fraction characteristics need to be developed as indicies that can be related to specific soil functions. The general effects of organic management on prominsing indicies of SOM status (POM and a rapid measure of base hydrolyzable N) were determined by comparing the characteristics of organic and conventionally managed soils obtained from nine long-term trials in North America. In addition, a more detailed study was conducted of POM and of hydrolyzable N fractions (including amino-acids, amino sugars) at a site where use of organic practices failed to increase SOM. In the multi-site comparrison, legume- and manure-based organic systems performed equally well in their ability to increase the quantity of SOM as well as enrich the... |
