Title
Research with nitrogen fertilizer emphasizes fertilize crop—not crop residue
B. A. Krantz; F Broadbent; W. M. Williams; et al. DOAJ (DOAJ: Directory of Open Access Journals) 1968
Other claims from this paper (6)
- Intervention effect Nitrogen application to the crop was more efficient and effective than application to prior residues.
- Association Infiltration increase from residues was inversely related to residue nitrogen content.
- Intervention effect Low-nitrogen residues had a longer-lasting effect than high-nitrogen residues.
- Intervention effect Nitrogen application to barley residue significantly reduced its beneficial infiltration effect.
- Intervention effect Straw with fertilizer nitrogen greatly reduced fertilizer nitrogen uptake by subsequent crops.
- Recommendation Fine shredding and early incorporation of residues into moist soil are recommended to avoid planting interference.
