Behavior of Chemichal Variables in a Soilless Crop System for Carantion in the Bogota Plateau ; Comportamiento de Variables Químicas en un Sistema de Cultivo sin Suelo para Clavel en la Sabana de Bogotá

To optimize the management of fertigation in the soilless crops is essential to know the behavior of chemical variables of the solution, and of the substrates. The aim of this study was to determine the behavior of pH, electrical conductivity (EC), cation exchange capacity (CEC) and carbon nitrogen ratio (C:N) in tree substrates base on burned rice husk and coconut fiber; and pH and CE in the drainage, in a soilless system to carnation crop cv. Delphi, with three recycling percentages and in different phenological developmental stages. The trial was carried out with three different substrates... Mehr ...
