Refinement of soil biological properties with biochar addition in sweetcorn
O Siva Devika, P Ratna Prasad, P Prasuna Rani and R Lakshmi Pathy
Modern agricultural practices resulted in soil pollution and deleterious effect on soil enzymes and population which plays crucial role in maintaining soil properties. To mitigate this, ecologically safe and user friendly methods should be adopted. By keeping this in view a field experiment was conducted with seven treatments viz., control (no fertilizers) (T1), RDF (T2), RDF+Azophos (T3), 75% RDF+biochar @ 5 t ha-1 (T4),75% RDF+biochar @ 5 t ha-1+Azophos (T5), 75% RDF+FYM @ 5 t ha-1 (T6), 75% RDF+FYM @ 5 t ha-1+ Azophos (T7) in Randomised Block Design (RBD). Addition of organics showed a significant influence on the soil enzyme activity and population. Urease, alkaline phosphatase and dehydrogenase activities were higher in biochar treatments than that of remaining treatments, whereas acid phosphatase activity was significantly superior in FYM applied treatments. Vigorous proliferation of bacterial and actinomycetes populations were observed in FYM supplied treatments whereas fungal colonies were more in biochar applied soils.
