AMES, Iowa -- There are many definitions of stewardship, but a basic definition is “the responsibility to care for resources.” When applying the term stewardship to manure management we could define it as the “responsibility to collect, transport and apply manure to meet crop nutrient needs while minimizing impacts on resources.”
Manure application timing is a big part of stewardship and one concern with timing is the application of manure in late winter. In the most basic terms – manure should not be applied at this time of year. This statement applies to all sources of manure.
