The study looked at different ways of preparing soil for planting winter wheat in Luoyang. They compared reduced tillage, no-tillage, subsoiling, and conventional tillage. No-tillage and subsoiling improved soil moisture before planting compared to conventional tillage. Subsoiling resulted in the highest crop yields and water use efficiency, followed by no-tillage and reduced tillage. Therefore, subsoiling is recommended for farmers in Luoyang to improve their winter wheat crops.
