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.
