1. Deep fertilization effects on potato production and GHG emissions depend on soil C:N:P-enzyme interactions: Evidence from a 4-year study
2. Maize yield and nitrogen use efficiency are increased by optimizing nitrogen fertilizer depth under film mulching in semiarid region
3. Evaluate the impacts of different straw returning rates on soil quality and field environmental sustainability of film mulching or non-mulching farmland in semiarid region
