That's one of the lessons learned from a manure on pasture test site south of La Broquerie.
The project looked at the effects of manure and various haying or grazing options.
Dr. Don Flaten explains the project has shown a number of techniques can be used to follow the forthcoming regulations.
Changing your livestock's diet, growing an excellent crop, and harvesting manured fields with hay rather than grazing are all ways that can help.
The overall best approach is to remove as much phosphorus as you can from the land during harvest so you can keep your manure application levels high.
Flaten stresses the test site has shown improvements over its three year lifespan, and has stayed within proposed guidlines for phosphorus.
