3.4 Improvement in soil physico-chemical properties under SMSTs
Results showed significant impact (p<0.05) of impact of SMSTs on soil properties viz., EC, SOC, soil water status (Fig. 5) and SOM, available N, P, and K (Fig. 6). However, SMSTs showed non-significant impact on soil pH. The value of EC (0.21) was observed significantly higher in SCCBT compare to other treatments. Significantly higher soil moisture (%) content was observed in SCCBT and SBT but it was lowest in SS. Both the SOC and SOM increased significantly under different SMSTs practices. The highest available N2O was reported with intercropping practice (SCCBT) which was significantly different from other treatments. The statistically higher availability of P2O5 was reported in SCCBT followed by SBT and lowest was recorded in the SS and SST. The SMSTs (SCCBT, SBT, and SSTS) also showed significant effect on availability of K2O compared to SS. The available K found to increase by 54% due to SWC practices in sapota.
