Quantitative Evaluation of the Native Fertility of Tropical Soils

Installation

About

An implementation of the QUEFTS (Quantitative Evaluation of the Native Fertility of Tropical Soils) model. The model (1) estimates native nutrient (N, P, K) supply of soils from a few soil chemical properties; and (2) computes crop yield given that supply, crop parameters, fertilizer application, and crop attainable yield. See Janssen et al. (1990) doi:10.1016/0016-7061(90)90021-Z for the technical details and Sattari et al. (2014) doi:10.1016/j.fcr.2013.12.005 for a recent evaluation and improvements.
