In an incubation experiment, the changes in physio-chemical properties and the periodical release of nutrients with fortified organic manures to a coastal saline sodic soil was studied. The experimental soil was collected from the farmer’s field at Sillankuppam village, Cuddalore district. The FeSO4+ZnSO4 fortified green leaf manure and coir pith significantly exerted a favourable effect on reducing the salinity and sodicity and increasing the availability of major and micronutrients in soil. Among the organics, micronutrients fortified green manure was associated with the greatest improvement in physio-chemical properties and nutrient availability.

Abstract


In an incubation experiment, the changes in physio-chemical properties and the periodical release of nutrients with fortified organic manures to a coastal saline sodic soil was studied. The experimental soil was collected from the farmer’s field at Sillankuppam village, Cuddalore district. The FeSO4+ZnSO4 fortified green leaf manure and coir pith significantly exerted a favourable effect on reducing the salinity and sodicity and increasing the availability of major and micronutrients in soil. Among the organics, micronutrients fortified green manure was associated with the greatest improvement in physio-chemical properties and nutrient availability.
