Lanthanum-modified biochar for the selective and efficient adsorption of ammonium nitrogen in wastewater

Biochar has been widely applied in wastewater treatment and agricultural applications; however, its practical utilization is limited by poor selectivity and insufficient adsorption capacity. In this study, La2O3-modified biochars were prepared from rapeseed straw (RS), corn straw (BC), rice husk (RH), and cotton stalk...

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...
