Effect of Green Manure on Water-Stable Soil Aggregates and Carbon Storage in Paddy Soil

Green manure, used for eco-friendly agriculture, supplies organic matter (OM) and nutrients to soil improves fertility. manuring also has the potential affect physical stability carbon storage. The objective of this study was investigate effect green manure on water-stable aggregates stock in paddy. Soil samples were collected from 3 treatments Chungcheongnam-do Agricultural Research Extension Services 29 April 2022; Control (CN), treatment (GM), Chemical fertilizer (NPK). Water-stable aggregate fractions (<53 µm, 53 - 250 >250 µm), contents bulk fractions, total analyzed. Carbon content GM 15% higher than NPK. However, there no significant difference (Mg C ha-1) ratio (%) percent macro-aggregates (>250 µm) micro-aggregates (53 significantly As a result, promoted aggregation stabilized aggregates. These results confirmed that nutrient supply, storage stability.Distribution each fraction treatments: CN, control; NPK, chemical treatment; GM, treatment.
