Abstract:
An incubation study was carried out in the Department of Soil Science and Agricultural Chemistry, College of Agriculture Dapoli, during the years 2021-22 and 2022-23 to evaluate the impact of straight and mixed fertilizers on periodic nutrient availability in lateritic soils of Konkan. There were three levels of recommended dose of nitrogen viz. 100, 80 and 60 percent through Konkan Annapurna Briquettes (KAB) with and without fertilization of zinc and boron. The recommended dose of straight fertilizers with and without zinc and boron was also included in the experiment. The result revealed that, the treatment effect on soil reaction, electrical conductivity and organic carbon were not affected significantly in most of the samplings (30, 60, 90 and 120 DAI) during both the years of investigation. The available nitrogen content in soil was found to be increased up to 90 DAI and then slightly decreased at 120 DAI. Available phosphorus and potassium content in soil was found to be increased periodically from 30 DAI to 120 DAI. The highest content of available Zn and B at 30, 60, 90 and 120 DAI was observed in the treatment comprised of 100 percent N through Konkan Annapurna Briquettes (KAB) fortified with 2 kg boron and 3 kg zinc ha^-1.
