Evaluation of a New Approach to the 15Nitrogen Isotope Dilution Technique, for Estimating, in the Field, Crop Nitrogen Uptake from Organic Residues
Crop residue return is a nutrient conservation practice that benefits crop production while also improving soil quality. One of the difficulties that scientists encountered was determining a reliable technique for measuring N release from these residues and tracking their fate in the plant-soil system. The disadvantage of the direct isotopic labeling method, which involves labeling…
