Preliminary soil physicochemical properties of experimental sites soil samples before planting.

Location	BD (g·cm^−3)	pH	EA cmol (+) kg^−1s	CEC (meq/100 g soil)	OC (%)	AP (ppm)	TN (%)	SO4/S (ppm)	B (ppm)	K cmol (+) kg^−1s	Ca cmol (+) kg^−1s	PBS (%)
OnS	1.14	5.14	0.98	19.6	1.13	4.36	0.14	5.41	0.428	1.262	6.8	84.4
