Comparison of Compaction Alleviation Methods on Soil Health and Greenhouse Gas Emissions

Soil compaction can occur due to trafficking by heavy equipment and be exacerbated unfavourable conditions such as wet weather. Compaction restrict crop growth increase waterlogging, which the production of greenhouse gas nitrous oxide. Cultivation used alleviate compaction, but this have negative impacts on earthworm abundance carbon dioxide. In study, a field was purposefully compacted using trafficking, then in replicated plot experiment, ploughing, low disturbance subsoiling application mycorrhizal inoculant were compared methods alleviation, over two years cropping. These terms bulk density, penetration resistance, yield, emissions abundance. Ploughing alleviated topsoil measured density penetrometer increased biomass one year although no yield differences seen. Earthworm reduced both cultivated plots, dioxide flux significantly, not significant summer months. Outside months, oxide non-cultivated treatments, attributed denitrifying activity under conditions.
