Overview

Nutrient balance consists of determining the amounts accumulated in plant organs, which is essential for making fertilisation recommendations according to actual nutritional requirements. The objective of this study was to determine the accumulated amounts of macro- and micronutrients and Na in ""Prata Anã"" banana trees grown in northern Minas Gerais, based on the analysis of mother, daughter, and granddaughter plants that make up the ""family"". The experiment was conducted in a commercial banana plantation of the ""Prata Anã"" cultivar, which was five years old. Four families were sampled: mother, daughter and granddaughter, and dissected into rhizomes, leaf sheaths, leaf blades, stems and bunches, which were evaluated in the laboratory for the levels and contents of N, Cu, Fe, Mn, Zn, Na, P, K, S, Ca and Mg. The total N accumulated in the family was 200,929 mg, with 16% of N exported by the fruits, returning 46% to the soil through the leaf sheaths and blades plus the stalk of the mother plant at the time of harvest. In descending order, the accumulation of micronutrients was Mn > Fe > Zn > Cu. K was the macronutrient most accumulated by the plants and the most returnable to the soil after harvest.
