Soil total exchangeable bases
WebSoils with pH < 4.5 often have high exchangeable hydrogen and aluminium (kg/ha; with high % hydrogen and aluminium base saturation). Soil Salinity - An electrical conductivity (EC) greater than the texture guidelines (e.g. > 0.2 dS/m heavy soil) may indicate a salinity issue. If the Exchangeable Sodium Percentage (ESP) or % Exchangeable Sodium ... WebExchangeable acidity. Soil acidity is one of the most important soil factors which affect plant growth and ultimately limit crop production and profitability (Fageria, 2009), and its problems are common in all regions where precipitation is high enough to leach appreciable amounts of exchangeable bases from the soil surface (Achalu et al., 2012

WebThis soil quality is decisive for successful low level input farming and to some extent also for intermediate input levels. Diagnostics related to nutrient availability are manifold. … Webtotal potential acidity of the soils varied from 29.43-61.32 cmol(p +)/kg. It was apparent that the total potential acidity in most of the soils, decreased with the depth of soils (Figure 1). This might be due to the deposition of exchangeable bases with increasing soil depth. The higher values of the total potential acidity
