Abstract

Abstract Wastewater-derived struvite is a promising phosphorus (P) fertilizer but more information on its behaviour in soil is needed to guide management practices for this slow-release fertilizer. After 20 days of incubation in two contrasting low-P soils in Petri dishes at two temperatures, the Olsen-P concentrations in soil surrounding struvite granules were 30–122 mg kg−1, which were much lower than after amendment with monoammonium phosphate (MAP) (435–1063 mg kg−1). Olsen-P concentrations further from the granule showed that MAP fertilized a larger volume of soil than struvite. Thus, the fertilizing effect of struvite may be very localized in soil.

废水颗粒鸟粪石在马尼托巴省对比土壤上的施肥效果

摘要废水来源的鸟粪石是一种很有前途的磷（P）肥料，但需要更多关于其在土壤中行为的信息来指导这种缓释肥料的管理实践。在培养皿中的两种对比低磷土壤中，在两种温度下培养20天后，鸟粪石颗粒周围土壤中的Olsen-P浓度为30–122 mg kg−1，远低于用磷酸一铵（MAP）改良后的浓度（435–1063 mg kg−）。离颗粒更远的Olsen-P浓度表明，MAP比鸟粪石施肥的土壤体积更大。因此，鸟粪石的施肥作用可能在土壤中非常局限。

期刊介绍： The Canadian Journal of Soil Science is an international peer-reviewed journal published in cooperation with the Canadian Society of Soil Science. The journal publishes original research on the use, management, structure and development of soils and draws from the disciplines of soil science, agrometeorology, ecology, agricultural engineering, environmental science, hydrology, forestry, geology, geography and climatology. Research is published in a number of topic sections including: agrometeorology; ecology, biological processes and plant interactions; composition and chemical processes; physical processes and interfaces; genesis, landscape processes and relationships; contamination and environmental stewardship; and management for agricultural, forestry and urban uses.
