Enhancing LysteGro biofertilizer product formulation for increased soil phosphorus availability in agricultural crop production

循环利用有机磷浓度显著的有机改进剂，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值。生物固体磷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，它比肥料和某些类型的粪肥更不适合植物。LysteGro提供了一种可持续的方法来建立土壤P浓度，但需要进一步的信息来帮助确定现有的和新的配方如何影响施用后的磷有效性。该项目的目标是研究LysteGro产品的不同配方，以开发最具农业效益和环境可持续性的土壤改良剂。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产品的配方，以增强不同农业土壤中的P动态并优化植物吸收率。Lystek是一家快速发展的公司，服务于北美各地市政当局的需求，将废水固体转化为商业上可行和安全的农业土壤改良剂。本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输送磷的功效的知识。这些成果将大大提高Lystek在加拿大和美国开发新市场的能力。此外，Lystek将能够为农民提供有关磷肥可用性的更好信息，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传统土壤测试的基础上，为农民提供特定肥力保证的能力有限。Lystek将与Price博士合作，积极参与开展研究，以开发知识，使其产品在农业市场上更具竞争力。

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.
