Effect of integrated nutrient management on some soil properties in mango orchard

Mango orchard soils of Uttar Pradesh are generally poor in essential soil nutrients and low fertility had impacted productivity as well as fruit quality. Integrated nutrient management with different organic and inorganic substrates may be a boon to improvement in soil processes and thereby productivity of the orchards. Results from an experiment on integrated nutrient management for mango orchard indicated improvement in soil properties. Improvement in soil organic carbon (SOC) content (0.45%) during four years of experimentation was recorded over the initial level of 0.21%. Soil moisture retention improved with organic mulching. Microbial activity in the form of dehydrogenase activity was also enhanced by integration of organics particularly vermicompost. Positive effect of different nutrient sources on availability of NPK and DTPA-extractable micronutrients were also revealed. This record was migrated from the OpenDepot repository service in June, 2017 before shutting down.
