| Abstract | The aim of the study was to evaluate the environmental fate of recovered manure phosphates for their effective use as crop fertilizers.A greenhouse study was conducted to evaluate the leaching potential and vertical distribution of total and plant-available P in a deep sandy Coastal Plain soil of the southern US fertilized with recovered P from liquid pig manure (SRP) and solid broiler litter (LRP). The recovered manure P sources were compared to commercial triple superphosphate (TSP) and raw broiler litter (BL) applied at a single rate of 170 kg P$_{2}$O$_{5}$ ha$^{−1}$ to 71-cm-tall soil columns with and without cotton plants. All materials were uniformly mixed into the surface 15 cm of soil in each column. All treated and control (unfertilised) soil columns were leached weekly with distilled water for 8 weeks. The water obtained after leaching the soil columns was analysed for total P. Cotton plant material was analysed for P content, and the soil columns were sectioned to determine the vertical distributions of total and plant-available P (Mehlich 3 test).The vertical soil P distribution showed that most of the total and plant-available P applied with SRP, LRP, and BL materials remained within the top 15-cm of the soil columns, where materials were initially applied. The significant increase of both total and soil available P within 15–22.5 cm of soil columns treated with TSP indicated translocation and potential leaching of P applied as TSP. In the short term of this study (8 weeks), the soil leaching potential of both LRP and SRP was lower than the more water-soluble commercial TSP fertilizer.The use of recovered P could minimize manure P losses into the environment from confined animal production and provide a recycled P source for use as crop fertilizer. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
