  "Description": "An implementation of the QUEFTS (Quantitative Evaluation\nof the Native Fertility of Tropical Soils) model. The model (1)\nestimates native nutrient (N, P, K) supply of soils from a few\nsoil chemical properties; and (2) computes crop yield given\nthat supply, crop parameters, fertilizer application, and crop\nattainable yield. See Janssen et al. (1990)\n<doi:10.1016/0016-7061(90)90021-Z> for the technical details\nand Sattari et al. (2014) <doi:10.1016/j.fcr.2013.12.005> for a\nrecent evaluation and improvements. There are also functions to\ncompute optimal fertilizer application rates.",
