PHOSPHORUS MANAGEMENT THROUGH THE APPLICATION OF RECYCLED FERTILIZERS IN ECOLOGICAL WHEAT PRODUCTION.

With the growth of the population, agricultural production has intensified, and in order to sustain itself, sustainable provision of soil with phosphorus, which is in an accessible form for plants, is crucial. For this reason, it is necessary to think of ways to "recover" phosphorus through the production of recycled phosphorus fertilizers. The experimental part of this paper covers tests to determine the following parameters: soil nutrient content, wheat development stage, plant height, water consumption, chlorophyll content, and yield (straw and grain). The aim of the study is to determine, with all necessary measurements and analyzes, whether and to what extent there are differences in the use of manure (Farmyard Manure), P-Rock Morocco, Dolophos, Berliner Pflanze on the growth, development and yield of wheat in relation to the part of the experiment that does not contain none of the fertilizers listed. The use of recycled fertilizers in organic wheat production can increase sustainability, given the fact that they are slow release nutrients, and their application helps to close the cycle of phosphorus in nature.
