ABSTRACT

Banana crops require large amounts of fertilizers to maintain nutrients levels and achieve satisfactory yields. The use of biological fertilizers combined with organic waste is an efficient and sustainable option for agricultural production. Therefore, this study evaluated the use of a biological fertilizer combined with sewage sludge to make nutrients available in banana crops. We conducted a field experiment in a randomized block design, with four blocks and five repetitions per block in a subdivided plot scheme. The experiment lasted two years. We performed the soil and plant chemical analysis and we also assessed the plant biometric data. The lowest dose of biological fertilizer combined with sewage sludge increased P content in the soil in the first and second collections, but decreased in the third collection. The highest nutrient levels in the soil and plant were attained when biological fertilizer was applied with sewage sludge; however, high Ca content caused an imbalance of exchangeable bases in the soil solution.

摘要

香蕉作物需要大量肥料来维持养分水平并获得令人满意的产量。将生物肥料与有机废物结合使用是农业生产的一种有效且可持续的选择。因此，本研究评估了生物肥料与污水污泥的结合使用，以提高香蕉作物的养分利用率。我们在随机区组设计中进行了田间试验，在细分的地块方案中有四个区组，每个区组重复五次。实验持续了两年。我们进行了土壤和植物化学分析，还评估了植物生物特征数据。最低剂量的生物肥料与污水污泥结合在第一次和第二次收集中增加了土壤中的磷含量，但在第三次收集中减少了。将生物肥料与污水污泥一起施用时，土壤和植物中的养分含量最高；然而，高钙含量会导致土壤溶液中可交换碱基的不平衡。
