Phosphorus

Our understanding of how phosphorus contributes to algal blooms—like the infamous Lake Erie cyanobacteria explosions in recent years—continues to evolve. Tune into these videos to learn more about dissolved reactive phosphorus, P that is tightly bound to soil particles, and other contributors to eutrophication, and to see how innovative farmers, crop consultants and programs are helping tackle the challenges.

N vs. P: Impacts on Algae

Dr. Laura Johnson of the National Center for Water Quality Research at Heidelberg University explains how N and P impact water quality in different environments.
Making P Available

Conservation practices like no-till and cover cropping do more than keep phosphorus from running off your fields—they can help build and unlock a storehouse of soil P, says Hans Kok of CTIC."
No P on Corn for 6 Years

Les Seiler and his brother Jerry haven't applied P on their corn crops for 6 years. Les explains why that works for them.
Pay Attention to What's Leaving This Farm

Les Seiler explains why he's excited to host a water quality monitoring study at the edge of one of his fields.
NTT: Field-Scale Modeling

Judy Smith of Heidelberg University's National Center for Water Quality Research explains why NTT is such a useful tool for farmers, crop consultants and others interested in field-scale modeling of nutrient movement.
Wheat Boosts Soil Health

Les Seiler explains how returning wheat to a corn/soybean rotation helped him and his brother build soil organic matter after years of stagnation.
