Quantifying soil quality in a horticultural-cover cropping system

Core Ideas:

This study compared 3 soil quality tests in a vegetable system with cover crops after 6 years. Compared to other commercial soil quality tests, a weighted-approach which only used measurements that detected differences, provided the most accurate score. Organic matter, evolved NH3-N, CO2-C, water extractable organic C, and pH were key measurements. Cover crops improved soil quality and tomato marketable fruit yield.
