Green Manure Decomposition, Nutrient Release and Crop Response R package GreenManureR version 0.1.0 Tools for analysing green manure and cover crop experiments, for example with Mucuna, sunhemp and dhaincha. Fits single-pool, double-pool and asymptotic litterbag decomposition models and ranks them by the corrected Akaike information criterion, estimates the time to 50 percent mass loss with Monte-Carlo confidence intervals, and quantifies nitrogen, phosphorus, potassium and other nutrient release over time. Further functions compute nutrient inputs, crop uptake, apparent nitrogen recovery and fertilizer nitrogen replacement value, estimate residual effects of green manures on succeeding kharif and rabi crops, link decomposition, nutrient release and crop response in a joint analysis, and generate standardized tables, diagnostic plots and a Word report.
