Soil samples were collected from direct seeded, double crop lands of Kuttanadu paddy fields [Ramankary Block, Alappuzha District, Kerala] maintained under a particular nutrient status for the last five years. Soil samples were obtained during the Kharif crop season at the tillering stage of the crop. Four treatments were used in the experiment and were numbered as T1, T2, T3 and T4.Various physical,chemical and biological parameters of the soil samples were studied. Among the different treatments analysed T4 recorded the highest values for most of the parameters such as amount of available phosphorous, organic carbon and micronutrients. The microbial diversity as indicated by bacterial and fungal CFU count also exhibited highest value in T4. In T4 the field was fertilized with N, P and K on soil analysis basis at the rate of 90:45:45 kg/ha along with lime at the rate of 250kg/ha and farmyard manure at the rate 5 ton/ha.
