Louisiana: Fall Phosphorus, Potassium Application Considerations Oct 22, 2022
Louisiana producers mostly use triple superphosphate (TSP; 0-46-0) for Phosphorus (P) fertilization and muriate of potash (MoP; 0-0-60) for potassium (K) fertilization and apply both fertilizers mostly in the Fall […]
Soil Nutrient Test Results Can Vary When Soil Is Very Dry, Study Shows Oct 19, 2022
Very dry conditions, like those seen in most of Arkansas this fall, impact two aspects of soil sampling that make it hard to measure how much phosphorus and potassium are […]
Alabama: Understanding Pathways of Soil Phosphorus Loss Jun 1, 2020
Educating ourselves about how phosphorus enters water bodies is important for agroecosystem management. Learn about phosphorus loss pathways from phosphorus-enriched soils. Phosphorus (P) is one of the primary nutrients essential […]
Minnesota: Optimal Soil Phosphorus, Potassium Levels – Podcast Apr 2, 2020
In this episode of the Nutrient Management Podcast, three U of M researchers discuss optimal phosphorus and potassium levels in the soil. What are some key takeaways that growers should know about […]
Ohio: No-Till – The Importance of Phosphorus Management Mar 11, 2020
Left untilled, fields gain organic matter and maintain high yields, but there’s a tradeoff to consider when deciding not to till. Fields that aren’t tilled are less likely to erode, […]
Minnesota Soybeans: Another Look at Phosphorus Fertilizer Application Timing Mar 3, 2020
In a recent blog post, I discussed the lack of a need for direct application of phosphorus fertilizer directly ahead of soybean. After discussions with crop consultants, I decided to […]
Minnesota: Corn-Soy Rotation – Phosphorus Only Needed Every Other Year Feb 4, 2020
In pursuit of maximum yields in two-year corn-soy rotations, some farmers are now applying phosphorus (P) fertilizer every year. A 10-year study by University of Minnesota scientists that ended in […]
Phosphorus Management: 8 Steps to Reduce Edge of Field Losses Oct 17, 2019
A new factsheet highlights eight steps to reducing edge of field P losses while maintain soils for increase crop production. The Phosphorus Nutrient Management for Yield and Reduced P Loss […]
Iowa Corn, Soybeans: P and K Management Following Highly Variable Yields Oct 2, 2019
Very variable weather this season will result in variable corn and soybean yield within and between fields. Entire fields or portions of fields were planted later than usual or were […]
Illinois Corn, Soybeans: Fall Fertilizer Considerations in 2019 Oct 1, 2019
The high number of prevented-planting fields in some areas, the late start to harvest, and the inability to apply P and K fertilizer as planned last fall or this past […]
