Abstract

The waste generated in the production of wine and grape juice is characterized by a high concentration of organic matter, when properly treated, can serve as sustainable strategies for its use and destination, and among these, the production of biocompost. Thus, the objective of this study was to evaluate the process of composting grape marc, sheep manure, and mango leaves, evaluating in the biocompost its physical-chemical, nutritional and microbiological characteristics for use in agriculture. The composting pile assembly followed the proportion of 30% of sheep manure as nitrogenous material and 70% of carbon-rich material (divided into 50% of grape marc and 20% of hose leaves), the initial C/N ratio was 33:1, and the process lasted 120 days according to legislation. When evaluating the results, the process occurred in an accelerated manner, where at 30 days the biocompost was already stabilized, and at the end of the process (120 days) it presented a C/N ratio of 5.85, as well as acceptable levels for the macronutrients K and P, and without risk of phytotoxicity, and could be used as organic fertilizer or as soil conditioner, reducing environmentally inadequate destination and generating savings with their reinsertion in the production chain.

摘要

葡萄酒和葡萄汁生产过程中产生的废物的特点是有机物浓度高，如果处理得当，可以作为其使用和目的地的可持续策略，其中包括生物堆肥的生产。因此，本研究的目的是评估葡萄渣、羊粪和芒果叶的堆肥过程，评估生物堆肥中用于农业的物理化学、营养和微生物特征。堆肥堆按照30%的羊粪为含氮材料和70%的富碳材料（分为50%的葡萄渣和20%的软管叶）的比例，初始C/N比为33:1 ，并且这个过程根据法律持续了 120 天。在评估结果时，该过程以加速的方式发生，
