Causes clarification of the soil aggregates stability on mulched soil

Popis výsledku v původním jazyce

Soil aggregates have great effects on soil properties and soil functions. Mulching organic inputs has been known as a factor influencing soil aggregate stability. Our study aimed to reveal the causes of the higher stability of soil aggregates under organic mulches. The primary soil characteristics such as organic carbon Cox, humus quality, potential wettability index PWI, and aromaticity index iA were determined. The Cox was measured using rapid dichromate oxidation, and was measured using the UV Vis spectrophotometry. The PWI and iAR were determined according to the intensity of selected bands in diffuse reflectance infrared spectra. Results showed that mulched plots contained higher Cox content in aggregates in comparison with whole soil. This indicates that the carbon was stabilized within the aggregates and sequestrated into the soil. The iAR was significantly higher after using the organic mulches, the aliphatic components of the organic matter thus contribute more to the aggregates stabil
