Composting <br />Composting is managed, accelerated breakdown of organic materials by microbes (i.e, bacteria, <br />fungus and molds). The goal of the composting process is to provide these microbes with a <br />good environment that encourages quick and efficient manure breakdown. Effective <br />composting does the following. <br />• Locks in nutrients <br />• Speeds up the breakdown process <br />• Reduces the size of the pile <br />• Kills weed seeds and fly larvae <br />A manure pile will eventually breakdown if left alone but will lose nutrients and become <br />infested with unwanted organisms. <br />Guidelines <br />Start with a good compost site <br />• Choose a convenient location <br />• Make sure the site won't flood with water <br />• Make sure the location meets the manure stockpile site requirements <br />You may not be able to attain desired temperatures during winter in Minnesota. Stockpile manure over winter and resume composting in <br />the spring. <br />Let cool <br />Compost curing occurs in the last t to 2 months during which time the temperature will reduce to ambient levels. The finished product <br />will look like something between potting soil and large, dark brown wood chips depending on the material size. Finer material composts <br />more quickly. <br />Use <br />You can use finished compost for the following. <br />• Amending soil in a garden <br />• Tree mulching <br />• Potting soil <br />• Fertilizer for the yard, pasture or hay fields <br />Never spread more than 1/2 inch of compost at one time when spreading compost on a yard, pasture or hay field. <br />Using manure <br />Whether composted or not, you will eventually need to move and use the manure. You can use manure onsite by spreading it as a <br />fertilizer on an open area, pasture or field. <br />You can also haul manure offsite for fertilizing or composting. Use caution when spreading manure on pastures grazed by horses. Don't <br />spread manure on pastures if there are more than i horse per 2 acres. Spreading manure in heavily stocked pastures could result in <br />increased parasite exposure. <br />Spreading <br />Spreading manure for fertilizer is a great way to use it. Spreading the manure for its fertilizer value is an excellent way to use it. But, you <br />must use caution to prevent excess nutrient buildup, To determine how much manure to spread on a field: <br />• Determine the nutrient content of the manure. <br />o Several private labs can perform this test. <br />• Test the field's soil to determine how much manure the intended crop needs, <br />0 Only spread enough manure to produce a viable and maximum yielding crop. <br />
