Última Interpretation of soil phosphorus availability by Mehlich-3 in soils with contrasting phosphorus buffering capacity Rev. Bras. Ciênc. Solo Reis,Josimar Vieira dos; Alvarez,Víctor Hugo V.; Durigan,Renan Dinardi; Paulucio,Rodrigo Bazzarella; Cantarutti,Reinaldo Bertola. ABSTRACT Increasingly rational use of phosphate fertilizers by agriculture is important, especially in Brazil, due to its importance for global food security and its high dependence on phosphate fertilizers for crop production. Thus, correlation and calibration researches with soil available phosphorus (P) extractants to improve the recommendation and the use of P are extremely important. Our objectives were (i) to determine soil P recovery rates and critical levels by the extractants Mehlich-1 (M1), Mehlich-3 (M3), and Ion Exchange Resin (RTI); (ii) to adjust predictive models of P recovery rates and critical levels for each extractant, as a function of soil properties related to the soil P buffer capacity, and (iii) to adjust the an interpretation table...

Solo Sousa,Jailson Silva; Neves,Júlio César Lima; Martinez,Herminia Emilia Prieto; Alvarez,Víctor Hugo V.. ABSTRACT: Research focused on adequate nutrition of plants is essential in modern coffee production to increase yield and develop more efficient management strategies with greater environmental and economic sustainability. The objectives of this study were to establish critical and optimal levels of soil fertility properties for high yielding Arabica coffee crops using the Boundary Line method and, then, relate the macronutrient contents in the diagnostic leaf of coffee to the macronutrients available in the soil using the Quadrant Diagram of the Plant-Soil Relationship (QDpsR). The study made use of a soil chemical analysis database, leaf macronutrient contents, and Arabica coffee yield from five representative coffee-growing regions in Minas Gerais. An...
