Condicionador de solos desenvolvido a partir de dejetos bovinos e pó de basalto

Abstract

The present study proposes to develop and analyze a soil conditioner obtained from bovine manure and different sources of phosphorus, with satisfactory agronomic efficiency, using beans as a test crop. Organic waste was collected on a family owned milk production in Mangueirinha-PR. For the preparation of the soil conditioner, five procedures were used i) manure and powder of basaltic rock; ii) manure and natural yoorin phosphate; iii) natural manure and phosphate and iv) simple manure and superphosphate; v) manure only. The buckets with the compost were housed in a greenhouse for fermentation and moisture reduction. After the product is ready, it will be applied to the bean culture, in a greenhouse, grown in pots. In the bean harvest, the stem diameter, the plant height were analyzed and, immediately after the material has dried, the dry masses of the roots and areas were weighed. The soil conditioner produced, met the requirement of being of low environmental impact, however, it did not prove to be advantageous and efficient agronomically for the bean culture.
