Última Boron extraction and vertical mobility in Paraná State oxisol, Brazil Rev. Bras. Ciênc. Solo Oliveira Neto,Waldemar de; Muniz,Antonio Saraiva; Silva,Maria Anita Gonçalves da; Castro,Cesar de; Borkert,Clovis Manuel. The deficiency or excess of micronutrients has been determined by analyses of soil and plant tissue. In Brazil, the lack of studies that would define and standardize extraction and determination methods, as well as lack of correlation and calibration studies, makes it difficult to establish limits of concentration classes for analysis interpretation and fertilizer recommendations for crops. A specific extractor for soil analysis is sometimes chosen due to the ease of use in the laboratory and not in view of its efficiency in determining a bioavailable nutrient. The objectives of this study were to: (a) evaluate B concentrations in the soil as related to the fertilizer rate, soil depth and extractor; (b) verify the nutrient movement in the soil profile; (c)...
