title: 'Rquefts: Quantitative Evaluation of the Native Fertility of Tropical Soils'
version: 1.2-4
doi: 10.32614/CRAN.package.Rquefts
abstract: 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.
