Acidifying Composts from Vegetable Crop Wastes To Prepare Growing Media for Containerized Crops

An inventory of materials suitable for use as growing media for ornamental potted plant production in Spain has been prepared. Special attention has been paid to solid organic wastes generated by production, industrial and consumer activities. Information obtained from this study has been organised into two data bases. Data base 1 contains the "General Characteristics" file of more than 105 materials. In this file, data are available regarding generation points, material availability, uses, cost, disposal expenses, etc. Data base 2 is comprised of the "Specific Properties" file of 63 materials selected from data base 1. The main physical, chemical and biological properties of these materials as container media have been characterised, and the results obtained have been compiled. Finally, a computerised data bank has been created which can be found in the home page of the Spanish Ministry of Agriculture, Fisheries and Food (http://agritel2.mapya.es/sustratos/). Show more
