Integrated diagnosis and ranges of nutrients in the soil for the cultivation of beans (Phaseolus vulgaris) in Cerrado region. cultrop [online]. 2019, vol.40, n.4, e03.  Epub 01-Dez-2019.

The Integrated Diagnostic and Recommendation System (DRIS), although is commonly used in the interpretation of leaf analyzes, has been little used in soil chemical analysis. The corrective and fertilizer recommendations for the Cerrado region developed for the conventional cultivation system based on calibration studies, without including the current technological advances. In this sense, the objective was to establish the integrated diagnosis and nutrient ranges in soils under bean cultivation (P. vulgaris) in this region. Soil samples collected at the depth of 0-20 cm, having values of organic matter, Ca, Mg, K, P, S, Zn, B, Cu, Fe, Mn, base saturation and cation exchange capacity at pH 7. Ground rules DRIS standards and sufficiency ranges were established from farming with productivity equal to and greater than 2700 kg ha-1 of beans and these became applicable for recommendation fertilization of this crop in the region. Most established parameters presented discrepancy in relation to the theoretical framework that currently has for the region. DRIS standards and ranges should be regional and specific to direct seeding for high yield crops.
