WebMar 16, 2024 · Dehydrogenase enzyme activity is a measure of microbial oxidative functions in soil that is related to K nutrition and more broadly to soil quality (122, 123). Root-associated microbes, including Pseudomonas and Bacillus species, that solubilize or oxidize S, Zn, Mn and others non-NPK nutrients also have been identified (e.g., 124 – 126 ). WebApr 6, 2024 · This experiment found that there was a negative correlation between V max and soil organic carbon content at the different growth stages, which may indicate that the application of organic fertilizer affected enzyme concentration and activity more by changing the quality and type of soil organic matter and other soil properties than the …
