Soil quality changes under different fertilisation and cropping in a vertisol of Tamil Nadu
Author(s): K Sathiya Bama, and E Somasundaram
Abstract: The research project was initiated to monitor the changes in soil quality in the intensive cropping systems under different fertilisation in an irrigated uplands. Different nutrient management practices viz., 100% organic, 100% inorganic, 50% organic + 50% inorganic were practiced under intensive cropping systems viz., green manure-cotton-maize, green manure-chillies- sunflower and green manure- brinjal- sunflower. The results emanated from the experiment showed that, better soil quality parameters such as soil dehydrogenase activity (115.4 mg TPF/kg/24 hrs), nutrient availability, higher water soluble organic carbon (SOC) (174 mg/kg) and potassium permanganate oxidisable carbon (KMnO4 C) (562 mg/kg) and lower bulk density was observed in green manure- brinjal- sunflower cropping system. In the nutrient budgeting, negative N and K balance of 77.4 kg/ha and 3.5 kg/ha was recorded in the sunhemp-cotton-maize. Irrespective of the cropping system, MP3 recorded favourable soil quality parameters.
