WebSoil fertility and (micro)biological activities are prominent indicators of soil ecological functions interrelated with nutrient cycles and stocks. The responses of soil functions and belowground biota to degradation of natural ecosystems and land use changes have received little attention, especially in semi-arid ecosystems of mountainous areas that are … Web2 days ago · It is generally assumed that external nitrogen inputs are the primary N source for cHABs. However, in northern lakes, nitrogen inputs are typically low which suggests that internal nitrogen cycling, through heterotrophic organic matter decomposition or nitrogen fixation, may play a significant role in cHAB development and sustainment.
Web1. Increase Organic Matter Inputs. As organic matter such as manure and compost decays into humus, it improves soil structure and drainage, holds moisture, and provides nutrients to the soil. Perennial, grass-dominant pastures are effective in increasing organic matter. Crops are also a valuable source, and residues should be returned to the soil.
