Valuation of By-products Resulted from Industrial Processes in Soil Fertilization. A Case Study: Ash Used as Soil Fertilizer 1 2 for Apple Sapplings

摘要

One of the most important orchard threes is the apple. In order to obtain satisfactory development of apple saplings in nurseries, often expressed using the coefficient of slenderness, special concern must be focused on maintaining conditions, fertilization and phytosanitary treatments, mainly. This study emphasize the advantages of using ash resulted from durmast debris incineration in an industrial facility of energy producing, in conditions of using the phytosanitary treatment consisting in mixture Topsin 70 WDG, Dithane M 45 and Calypso 480 SC, for which was reported the highest coefficient of slenderness by entire study, equal to 5.42, while the weakest results were obtained under the unconventional treatment with Funres and Oleorgan and fertilization with magnetic fertilizer, with coefficient of slenderness of 3.21, and with N 15 ? ? P 15 K 15 , with coefficient of slenderness of 3.65.
