Fertilizer nutrients in dairy manure

Pdf created from MU Extension webpage, July 2022."Many dairy producers fall into one of two categories: (1) They are willing to make high capital and labor outlays to maximize the usage of their dairy wastes for crop production (2) They are willing to minimize the amount of nutrients returned to the land for crop production in exchange for a relatively low-cost and low-labor method of waste disposal. Producers in the first category usually use slurry systems with tanks for waste storage, and tank wagons with injectors to transport and apply the waste. Producers in the second category use lagoons for storage/treatment, and irrigation equipment to transport and apply the waste to their fields. To have value, wastes must be used in a manner that results in a salable product. This publication describes methods of recovering a portion of the plant nutrient value of dairy wastes."--Page 1.Reviewed by David Brune (Department of Agricultural Engineering), Charles D.
