In spite of its wide-world economic relevance, wine production generates a huge amount of waste that threatens the environment. A batch experiment was designed to assess the effect of the amendment of an agricultural soil with two winery wastes (perlite and bentonite wastes) in the immobilization of cyprodinil. Waste addition (0, 10, 20, 40, and 80 Mg ha(-1)) and different times of incubation of soil-waste mixtures (1, 30, and 120 days) were tested. The addition of wastes improved the soil's ability to immobilize cyprodinil, which was significantly correlated to total C content in soil-waste mixtures. Longer incubation times decreased the cyprodinil sorption possibly due to the mineralization of organic matter but also as a consequence of the high pH values reached after bentonite waste addition (up to 10.0). Cyprodinil desorption increased as the amount of waste added to soil, and the incubation time increased. The use of these winery wastes contributes to a more sustainable agriculture preventing fungicide mobilization to groundwater.
尽管葡萄酒生产在世界范围内具有重要的经济意义，但它也产生了大量威胁环境的废物。本批实验旨在评估在固定菌核利时，用两种酿酒厂废物（珍珠岩和膨润土废物）改良农业土壤的效果。测试了废物添加量（0、10、20、40 和 80 Mg ha(-1)) 和土壤-废物混合物的不同孵育时间（1、30 和 120 天）。废物的添加提高了土壤固定菌核利的能力，这与土壤-废物混合物中的总 C 含量显著相关。较长的孵育时间可能会由于有机质的矿化而降低菌核利的吸附，但也会由于膨润土废物添加后达到的高 pH 值（高达 10.0）而降低菌核利的吸附。随着添加到土壤中的废物量和孵育时间的增加，菌核利的解吸增加。使用这些酿酒厂废物有助于实现更可持续的农业，防止杀菌剂向地下水迁移。
