- ... Information on the effect of long‑term management on soil nutrients and chemical properties is scanty. We examined the 30‑year effect of tillage frequency and cropping sequence combination on dryland soil Olsen‑P, K, Ca, Mg, Na, SO(4)–S, and Zn concentrations, pH, electrical conductivity (EC), and cation exchange capacity (CEC) at the 0–120 cm depth and annualized crop yield in the northern Great ...
