ABSTRACT
Organic farming is gaining momentum in the country in past few years. Organic system of farming is claimed to be a sustainable system which helps in improving soil quality as well as helps in reducing environmental risks. A study was carried out for comparative evaluation of the effect of organic and integrated system of farming on soil fertility parameters in Kerala. Soil samples of 2 depths (0-15 cm and 15-30 cm) were collected from 10 certified organic farms and nearby integrated farms during 2018-19. Samples were collected from four districts of Kerala, namely Kannur, Wayanad, Palakkad and Trivandrum representing Northern, Hilly, Central and Southern agro climatic Zones of Kerala respectively and analysed for pH, EC, organic matter, available N, P, K, Ca, Mg, S and B. Except for pH and electrical conductivity all other parameters were found to be higher in organic system. However significant difference was noticed only in case of pH, Available Nitrogen, Potassium and Calcium in 0-15 cm surface soil. The study indicates organic farming is found to be enhancing soil fertility.
