After storage and handling, animal manures typically do not have crop nutrient ratios of N, P, and K that meet crop needs. This means that at least one nutrient will often be over- or under-applied. But what if we could create 'designer' manures to meet these needs? Organomineral fertilizers will be discussed along with ways to blend commercial fertilizers with manure in the 'do it yourself' fashion. The webinar will end with a perspective from the custom organic fertilizer industry.
