Verbatim
e0“the proportion of microaggregates (53–250 μm) did not show any significant difference in both layers.”
e1“SOC concentration of the top 15 cm soil depth and SOC stock of the top 30 cm soil increased significantly under NT compared to CT.”
t0“Soybean-Wheat”

- Intervention effect No tillage significantly increased topsoil SOC concentration and stock over conventional tillage.
- Intervention effect No tillage raised top 30 cm soil organic carbon stock by 9.2 percent over conventional tillage.
- Intervention effect No tillage increased macroaggregate proportion by 6.1 percent in the 0–5 cm layer.
- Intervention effect No tillage increased macroaggregate proportion by 2.7 percent in the 5–15 cm layer.
- Intervention effect Organic matter nutrient treatments raised SOC concentration and macroaggregation relative to NPK in the upper two layers.
- Intervention effect Organic matter application raised macroaggregation by 5.2 percent in the 0–5 cm layer.
- Intervention effect Organic matter application raised macroaggregation by 4.5 percent in the 5–15 cm layer.
- Intervention effect Tillage and nutrients did not significantly differ in SOC concentration and macroaggregates at 15–30 cm.
- Intervention effect Tillage did not significantly change profile soil water storage during the 2006 kharif season.
- Intervention effect NPK, FYM and NPK+FYM had less profile water storage than the other two nutrient treatments late in the soybean season.
