Corn Response To Wastewater-Recycled Phosphorus Fertilizers, Shane R. Ylagan, Kristofor R. Brye
Corn Response To Wastewater-Recycled Phosphorus Fertilizers, Shane R. Ylagan, Kristofor R. Brye
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The ability to recycle phosphorus (P) from wastewaters could provide a sustainable, continuous source of P that might also help protect surface water quality from P enrichment. The mineral struvite (MgNH4PO4 · 6H2O) is an understudied material that can be created from P- and nitrogen (N)-containing wastewater and has been shown to have agricultural fertilizer value. The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (Crystal Green; CG), diammonium phosphate (DAP), monoammonium phosphate (MAP), rock phosphate (RP), and triple superphosphate (TSP) on corn (Zea mays) response in a greenhouse pot study. …

Response Of Soybean Grown On A Claypan Soil In Southeastern Kansas To The Residual Of Different Plant Nutrient Sources And Tillage, D. W. Sweeney, P. Barnes, G. Pierzynski
Kansas Agricultural Experiment Station Research Reports
The residual effects of turkey litter and fertilizer amendments applied in previous years had little effect on the yield, yield components, and dry matter production of the following soybean crop grown in 2014.
Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer
Nitrogen, Phosphorus, And Potassium Fertilization For Newly Established Tall Fescue, D. W. Sweeney, J. L. Moyer
Kansas Agricultural Experiment Station Research Reports
First-year spring yields of tall fescue in 2013 responded to phosphorus (P) fertilization, but lodging at the R5 growth stage in the spring with higher P fertilization rates may have influenced subsequent fall harvest yields, which declined with increasing P rates. As N rates increased, R5 yields declined but fall harvest yields increased.
Short-Term Denitrification In The Metalimnion Of A Eutrophic Reservoir, Aki Kogo, Erin M. Grantz, Thad Scott
Short-Term Denitrification In The Metalimnion Of A Eutrophic Reservoir, Aki Kogo, Erin M. Grantz, Thad Scott
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Denitrification in metalimnetic water was examined under different conditions to determine how addition of nitrate (NO3 -) and particulate carbon (PC), aeration, and concentrations of nitrate affect denitrification. In the first experiment, water samples from a metalimnion were treated with different combinations of NO3 - and PC. Changes in excess N2 -N concentration for 10 days were measured using membrane inlet mass spectrometry (MIMS). The second experiment used the same treatments as the first experiment after aeration of water. Besides excess N2 -N concentrations, O2 concentrations were measured for 16 days. The third experiment examined how different initial concentrations of …
