Biosolids are defined as the solid, organic matter recycled from sewage waste and are often processed in a way that allows for their use in agricultural farming. There are concerns, however, regarding the safety of biosolids amendments in agricultural soils, particularly with respect to potential leaching of nutrients through the soil. If these amendments are applied to soils at an appropriate rate, however, and to crops that germinate and grow quickly, they could be a safe and efficient source of organic fertilizer. Turfgrass is grown as a perennial crop that can create complete ground cover and has a rather high root to shoot ratio. Turfgrasses grown for maintained areas require high amounts of fertilizer, especially nitrogen, and can benefit from increase organic matter as many turfgrasses are grown on sandy soils. The use of biosolids for turfgrass growth could be mutually beneficial for waste treatment plants and for turgrass managers alike as biosolids could potentially be an excellent source of organic fertilizer for establishment and maintenance. The objectives of this study are to determine the potential use of LysteGro biosolids for the establishment and maintenance of turfgrass on sod farms and potentially on other areas where turfgrass is maintained. Additionally, we are interested in the leaching potential of LysteGro biolosolids to ensure that their use will not lead to pollution of groundwater systems. The results of this study could lead to the use of an alternative organic fertilizer for the growth of turfgrass plants, and with additional testing, potentially other crops as well.

生物固体的定义是从污水废物中回收的固体有机物，通常以某种方式进行处理 这使得它们可以在农业耕作中使用。然而，也有人担心生物固体的安全性。 农业土壤中的改良剂，特别是在土壤中养分的潜在淋溶方面。如果 然而，这些改良剂适用于土壤和发芽生长的作物。 很快，它们就可以成为一种安全有效的有机肥料来源。 草坪草是一种多年生作物，可以形成完全的地面覆盖，并且有相当高的根部可供生长。 比率在养护地区种植的草坪草需要大量的化肥，特别是氮肥，而且可以 受益于增加有机质，因为许多草坪草生长在沙质土壤上。生物固体物的使用 草坪种植对垃圾处理厂和草坪管理者都是互惠互利的，因为 生物固体可能是建立和维护有机肥的极好来源。 这项研究的目的是确定LysteGro生物固体在建立和 草皮农场的草坪维护，以及可能在维护草坪的其他地区的草坪维护。 此外，我们对LysteGro生物固体的浸出潜力感兴趣，以确保它们的使用不会 导致地下水系统的污染。这项研究的结果可能会导致使用另一种选择 用于草坪植物生长的有机肥，并在进行额外测试的情况下，可能还包括其他作物。
