| Research Abstract |
Continuous application of cover crops increased soil carbon and activated important enzymes in soil. GHG (Greenhouse gas) was released when cover crops were incorporated, however it was inhibited by no-till cultivation. Fungi increased and water-stable aggregate was formed in the soil with application of gramineous cover crops. Mycorrhizal fungi were proliferated after decomposition of hairy vetch, one of legume cover crops, and supported phosphorus uptake into plant. Much amounts of N released by decomposition of legume cover crops were used for subsequent crops. Cover crops are important tool of organic agriculture with reduction of GHG.
