Description: This image illustrates loading a side delivery spreader with manure that had been picked up from a cattle pen. Towed by a tractor to a field for spreading, an apron at the bottom of the spreader moves the load to the front of the box where the manure is propelled out one side as illustrated in NAL #4962. Alternative equipment spreads the manure from the rear of the box (NAL #4959 & #4960). Consisting of feces and urine, and usually bedding, animal manure is a valuable source of nutrients for plants. It also improves organic matter content of the soil. Plowing or disking the soil soon after spreading the manure optimizes capture of manure nutrients and minimizes pollution from volatilization and/or runoff of manure nutrients.
