These represent typical analyses for each manure in Colorado. Desired N application. Determine how much nitrogen you will need from the manure application. From the total nitrogen the crop requires, subtract any nitrogen contributed from fertilizers, irrigation water, herbicide carriers, previous legume Crops, soil organic matter, residual soil nitrate and previous manure applications. The amount of manure to be applied to the field to achieve the desired application is 11 tons per acre.
Cattle manure application rates.
This table uses only the total nitrogen content of a manure, so it is an estimate of what will be available to the crop during the growing season. Use it to determine application rates until you can obtain more precise numbers. These are average contents for each type of manure in Colorado. These numbers assume that the manure will be incorporated immediately after application. Go to top of this page.
