Plot-specific N-fertilizer response curves generate fertilizer recommendations conducive to soil organic matter conservation. This involves curating the database by removing excessively high/low N-fertilizer use efficiencies (NfUE) known to deplete soil organic carbon.
Coupled plot-specific N-fertilizer response curves, P, K & attainable soil pH recommendations are generated. Such nutrient management plans (NMP) also include soil P & K critical thresholds for the fine-tuning of such sustainable fertilizer recommendations.
As an ergonomic alternative to current carbon-farming & soil-derived carbon-credits, this simple soil-samplingless protocol ensures that crop residues contain sufficient nitrogen to be properly humified as soil organic matter. RNCs also get around issues of additivity, leakage, permenance, etc.
