Rquefts: Quantitative Evaluation of the Native Fertility of Tropical Soils

An implementation of the QUEFTS (Quantitative Evaluation of the Native Fertility of Tropical Soils) model. The model estimates nutrient requirements for crops to achieve a target yield given native soil fertility, as estimated from a few soil chemical properties. 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.
