Short-term effects of Sulla residues and farmyard manure amendments on soil properties: cation exchange capacity (CEC), base cations (BC), and percentage base saturation (PBS)

Short-term effects of Sulla residues ( Hedysarum coronarium L .) and farmyard manure (FYM) were monitored under controlled conditions on silty-clay soil (soil SC) and silty-sandy soil (soil SS) collected from arid and semi-arid regions of Tunisia. The aim of this study was to examine the effects of...

Description
Summary:Short-term effects of Sulla residues ( Hedysarum coronarium L .) and farmyard manure (FYM) were monitored under controlled conditions on silty-clay soil (soil SC) and silty-sandy soil (soil SS) collected from arid and semi-arid regions of Tunisia. The aim of this study was to examine the effects of these amendments on soil properties, with specific emphasis on cation exchange capacity (CEC), base cations (BC), and percentage base saturation (PBS). The residues of Sulla and FYM were applied at equivalent field rates of 5 t ha −1 . After 3 months of incubation, the soil’s CEC, BC, and PBS were determined. The results indicate that soil changes are related to the nature of the type of organic input used. For instance, the CEC in the soil SC amended with FYM reached 32.5 meq 100 g −1 compared to the control soil (24.5 meq 100 g −1 ). The FYM amendment resulted in a 48% increase in soil BC compared to Sulla amendment (31%). As a result, PBS increased up to 73.3% after FYM addition, followed by Sulla amendment with 63.8% compared to the soil control (50.6%). The effect of soil texture is highlighted by the higher sorption capacity in soil SC, which is due to its higher fine fraction content compared to soil SS. This study suggests that the positive effects of Sulla and FYM are primarily related to their nature and biochemical composition.
