Variação na concentração e na quantidade de macro e micronutrientes no fruto do cafeeiro, durante o seu desenvolvimento

Abstract

This paper reports the variation in the concentration and in the amount of nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, copper, iron, manganese, molybdenum and zinc in the coffee berries during their growing period. The concentration of macro and micronutrients showed a tendency of reduction with the development of the coffee berries. On the other hand the amount of macronutrients and of iron, copper, boron and molybdenum increased continuously from the first month to the ripening stage of the coffee fruits. Zinc and manganese did not increase in the last three months previous of the ripening of the fruits.
