Soil exchangeable acidity
WebThe increasing trend of soil acidity and exchangeable Al 3+ in arable and abandoned lands are attributed to intensive cultivation and continuous use of acid forming inorganic fertilizers (Abdenna et al., 2007). Other changes in soils that may occur during soil acidification include loss of nutrients due to leaching, loss http://jal.xjegi.com/EN/10.1007/s40333-023-0100-x
