The recycling of organic amendments with significant concentrations of organic P, such as biosolids, is asustainable practice. Farmers who use biosolids often do so for the P fertilizer value to meet what crops requirefor growth. Biosolids-P is in a mixture of organic and inorganic forms that is less plant- available thanfertilizers and some types of manures due to physical and chemical changes during the treatment process.LysteGro provides a sustainable way to build soil P concentrations but further information is needed to helpdetermine how existing and new formulations affect phosphorus availability after application. The goal of thisproject is to study different formulation of the LysteGro product in order to develop the most agronomicallybeneficial and environmentally sustainable soil amendment. In this first time collaboration with the InnovativeWaste Management Program, Lystek will be working with researchers at Dalhousie University to developformulations of LysteGrow products that enhance P dynamics in different agricultural soils and optimize plantuptake rates. Lystek is a rapidly expanding company serving the needs of municipalities across the NorthAmerica to convert wastewater solids into commercially viable and safe agricultural soil amendments. Theoutcomes of this research will provide knowledge on the efficacy of current treatment processes andformulations to deliver phosphorus for crop production under different soil conditions. These results willsubstantially enhance the capacity for Lystek to develop new markets in Canada and the United States. Inaddition, Lystek will be able to provide farmers with better information on P availability to support their bestmanagement practices. Currently, Lystek is limited in their capacity to provide specific fertility guarantees tofarmers on the basis of the existing knowledge and the conventional soil tests provided by provincial soillaboratories. Lystek, working with Dr. Price, will be an active participant in conducting the research studies inorder to develop the knowledge to make its products more competitive in the agricultural marketplace.

回收含有大量有机磷的有机改良剂（例如生物固体）是可持续的做法。使用生物固体的农民通常这样做是为了满足作物生长所需的磷肥价值。 Biosolids-P 是有机和无机形式的混合物，由于处理过程中的物理和化学变化，植物可利用性比肥料和某些类型的粪肥低。LysteGro 提供了一种可持续的方法来建立土壤 P 浓度，但需要更多信息帮助确定现有和新配方如何影响施用后的磷利用率。该项目的目标是研究 LysteGro 产品的不同配方，以开发最具农艺效益和环境可持续的土壤改良剂。在与创新废物管理计划的首次合作中，Lystek 将与达尔豪斯大学的研究人员合作开发 LysteGrow 产品配方，以增强不同农业土壤中的磷动态并优化植物吸收率。 Lystek 是一家快速扩张的公司，致力于满足北美各城市的需求，将废水固体转化为商业上可行且安全的农业土壤改良剂。这项研究的结果将提供有关当前处理工艺和配方在不同土壤条件下为作物生产提供磷的功效的知识。这些成果将大幅增强Lystek开拓加拿大和美国新市场的能力。此外，Lystek 将能够为农民提供有关磷可用性的更好信息，以支持他们的最佳管理实践。目前，Lystek 在现有知识和省级土壤实验室提供的常规土壤测试的基础上向农民提供具体肥力保证的能力有限。 Lystek 将与 Price 博士合作，积极参与研究工作，以发展知识，使其产品在农业市场上更具竞争力。
