Subsoil tillage boosts sorghum yield in saline-alkali soils by alleviating constraints on root growth through integrated soil improvement.
To enhance crop productivity in saline-alkali soils, it is essential to overcome soil constraints that limit root growth. This study used sorghum as the test crop and conducted a field experiment in the Hetao Irrigation District of Inner Mongolia to compare subsoiling tillage (ST) with conventional tillage (CT). We eva...
