tailieunhanh - Zeolite: A soil conditioner

In many parts of the world food security is being affected due to declining quality and/or quantity of the soil resource base and climate change. In this context, farming with zeolites has drawn attention. Zeolites are natural aluminosilicates present in rocks in different part of the world. Use of zeolite has gained a momentum in the recent past owing to multitude of benefits accrued from them. Clinoptilolite Zeolites are useful in agriculture because of their large porosity, cation exchange capacity and selectivity for ammonium and potassium cations. They can be used both as carriers of nutrients and as a medium to free nutrients. (C, Sangeetha and P, Baskar, 2016).Natural zeolites has been reported to be used extensively as amendments for sandy soils. Zeolitic amendment is an effective way to improve soil condition in arid and semiarid environments (Yasuda et al., 1998). It was also found that application of soil amendments such as Clinoptilolite zeolite with composted manure improves soil physical properties such as soil CEC. Inorganic and organic fertilizer along with Clinoptilolit Zeolite showed the best N, P and K uptake in plant tissues because of less leaching of these nutrients and helps to retain nutrients in root zone by enhancing nutrient absorption. (Ahmed, 2010).Zeolites could be used as an effective additive to control the odour as they could adsorb the volatile substances like acetic acid, butanoic acid, isovaleric acid, indole and enhances effectiveness of the manure (Leggo, 2000).Zeolite acts as a superior substrate or carrier for the nutrients or acts as a slow-release source of nutrients to plants assuring higher yields. | 2020 9 1 1184-1206 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 1 2020 Journal homepage http Case Study https Zeolite A Soil Conditioner Binod Kalita1 Sarat Sekhar Bora2 and Bhabesh Gogoi3 Agronomy RARS Shillongani Agromeleorology KVK Udalguri 3Soil Science AICRP on IFS Assam Agricultural University Jorhal-785013 Assam India Corresponding author ABSTRACT Keywords Food Security Zeolite Fertilizer Article Info Accepted 15 December 2019 Available Online 20 January 2020 In many parts of the world food security is being affected due to declining quality and or quantity of the soil resource base and climate change.
