Effect of Organic Amendments and Gypsum on Physico Chemical Properties of Salt Affected Purna Valley Soils and Cotton Yield in Vidarbha Region

Impact of some Organic and Inorganic Amendments on some Soil Properties and Wheat Production under Saline-Sodic Soil

“…Also, ECe is indirectly related to the total concentration of soluble salts in soil and is a direct measurement of salinity. These results may attribute to the improvement in soil porosity and hydraulic conductivity as a result of soil amendments, which enhance the leaching of salts, as observed by Shah et al, (2013), Daur and Tatar (2013), Amer (2015), Hamad (2015), Zia-Ur-Rehman et al, (2016), Amer (2017), Kim et al, (2017), Saqib et al, (2017), Wafaa Hafez et al, (2017, Ravinder et al, (2017), Amer and Hashem (2018).…”

“…These results may be attributed to the role of biochar application in increasing of soil porosity through (i) pore contribution due to high-porosity of biochar, and (ii) improved aggregate stability (Hardie et al, 2014). Also, addition of gypsum led to a reduction in soil bulk density and a corresponding increase in soil porosity (Amer, 2015, Kim et al, 2017, Ravinder et al, 2017and Amer and Hashem , 2018. In addition, compost tea caused reduction in soil bulk density and an increase in soil porosity (Scheuerell and Mahaffee, 2004, Nasef et al, 2009, Enshrah and Fatma, 2016and Amer .2016.…”

“…Gypsum has a calcium content of 23%. The application of gypsum reduced ECe, SAR and ESP (Shah et al, ,2013, Daur and Tatar, 2013, Amer ,2015, Hamad ,2015, Zia-Ur-Rehman et al, 2016, Amer ,2017, Kima et al, 2017, Saqib et al, 2017, Wafaa Hafez et al, ,2017, Ravinder et al, 2017and Amer and Hashem, 2018, while the removal sodium efficiency calculated (RSE %) significantly increased by 46.67, 57.89 and 71.83% in soil treated by gypsum, gypsum + sand, and gypsum + rice straw, respectively, compared to that of the initial soil (Amer,2017).…”
