Lixiviados de Raquis de Plátano: Obtención y Usos Potenciales

Abstract

Banana is one of the most consumed fruits in the world. Besides its flavor and nutritional potential can be easily transported and stored. In Mexico many varieties of bananas are grown on a surface area of more than 70.000 hectares with a production of more than 2 million tons of fresh product per year. In most of the cases the banana-coffee diversified agrosystem is managed on the backyards and implies the use of a huge amount of diversity such as fruit and other tree species. Banana production causes a large amount of organic waste such as wasted fruits and rachis mainly. These are not properly used and could be reused as organic matter for the soil. In this work, the production and content of nutrients (macro and micro elements) of the banana rachis leachate in greenhouse in 4 kg trays each were evaluated. A yield of 30% of leachate repair was obtained. Potassium (K) is the most recovered element (1%) in alkaline leachate (pH 10). In this investigation, rachis leaching is proposed as a complementary alternative for crop nutrition due the large amount of nutrients that it contains.
