Guide to pig manure

Manure from pig operations provides an effective, low-cost source of nutrients for crops and pastures. However, manure handling can present a challenge on pig operations. Dependent on the circumstance, manure may be handled as either a solid or a fluid on the farm. Most small operations handle manure as solids, spreading the fertilizer throughout the year using conventional manure handling equipment like shovels, tractor-mounted loaders, skid loaders, and manure spreaders.

Manure consistency varies according to the age of the animals, the sort of feeds provided, and the sort of bedding employed in the operation. Confinement operations focus the fertilizer, while manure in pasture operations can be less concentrated. Many larger pig operations handle the fertilizer in the fluid form, which requires different types of equipment and structures for assembling and spreading the foods on fields.

Pig manure is a valuable by product that can be employed to enhance field crop production. Here are several useful facts regarding production rates and nutrient contents of pig manure:

– A 150-pound pig produces 9.5 pounds of solid waste every day, or 1.7 tons of manure annually.

– A 150-pound pig produces 1.2 gallons of fluid waste every day, or 440 gallons annually.

– Solid manure incorporates 7 pounds of nitrogen, 6 pounds of phosphorus, and 7 pounds of potassium per ton.

– Fluid manure incorporates 17 pounds of nitrogen, 10 pounds of phosphorus, and 16 pounds of potassium per 1000 gallons

– Pig operations with 100 animals on hand year-round produce 170 tons of solid manure, or 44,000 gallons of fluid manure annually. This manure would supply nutrients for approximately 10 acres of field corn on an annual basis and would require little additional purchased commercial fertilizer to meet crop needs.
