Organic fertilizer strategies for the production of strawberries an agroecological system

Introduction: among the organic strategies of agricultural production is composting. The aim of this study was to develop an organic fertilizer from horse manure and test it in the production of strawberries. Strawberry seedlings were planted, containing horse manure, birds, chemical fertilizers and only ravine soil. Soil samples were used to perform a chronic toxicity test. After harvesting, physical and antioxidant analyzes were performed on the fruits. Results: in the analysis of soil toxicity, a greater reproduction of colembolans was observed in the soil containing bird compost. As for physical-chemical analysis, strawberries produced with chemical and equine fertilizers had a lower moisture content. Strawberries produced with horse compost had a higher carbohydrate content. The horse compound helped to increase the presence of total phenolic compounds and the antioxidant activity of the produced strawberries. Conclusion: thus, the use of equine composting can be considered a sustainable option for the production of strawberries.
