MANURE PROVIDES FARMERS AN ALTERNATIVE NUTRIENT SOURCE AMID VOLATILE FERTILIZER MARKET

In the past year, the cost for urea and diammonium phosphate have more than doubled. With no end in sight, some producers are looking at alternatives like manure.

Daniel Andersen, associate professor at Iowa State University, says that farmers interested in integrating manure as a fertilizer have the possibility for great outcomes in terms of improved soil health and crop nutrition.

“One of the things I like to say is that manure is a complete fertilizer, but it isn’t always a balanced fertilizer,” says Andersen.

Andersen says that some manure will have more phosphate or excess nitrogen, when what the crop really needs is potassium. When deciding whether or not to spread manure, it’s important to determine the type of manure necessary for the particular crop type and current soil nutrient makeup. For example, if a farmer has planted a crop that needs a lot of phosphorus, but has soil that is low in phosphorus, they should shop around for nitrogen-rich manure, like poultry.

“Oftentimes manures can be only transported a few miles to keep price-competitive with synthetic fertilizers. With a liquid manure, that application distance is probably somewhere in the neighborhood of 1 to 5 miles that we’re willing to move it and still have it be cost-competitive with purchasing other synthetic fertilizers,
