commercial materials because they are priced according to percentage of protein. On the other
hand, barnyard materials vary considerably with age. The more a material breaks down, the more
nitrogen it loses. Most compost supplements are purchased dry and added dry, helping even distribution as well as enabling easy storage. It is also important that the raw materials used for composting be as fresh as possible. This insures maximum utilization of their properties. Baled straw stored
for a year and kept dry is fine, If the straw has gotten wet, moldy or otherwise started to decompose,
it should not be used.

This formula make approximately 7,000 pounds of compost at a 71% moisture content.
Although 7,000 pounds of compost seems like a large quantity, at a fill level of 20 pounds per
sq. ft., this will fill only 350 sq. ft. of beds or trays. Keep in mind that during the composting process
there is a gradual reduction in the the total volume of raw materials. Fully 20-30% of the dry matter
is consumed during Phase land another 10-15% during Phase II. In total, approximately 40%
of the dry matter is reduced by microbial and chemical processes. This loss of potential nutrients can not be avoided and demonstrates the importance of composting no longer than necessary.

Amia
The production of ammonia is essential to the composting process. Just as the carbohydrates
must be in a form that microbes can utilize, so must the nitrogen.
1. Ammonia supplies nitrogen for microbial use.
2. Ammonia is produced by microbes acting upon the protein contained in the supplements.

With the energy supplied by readily available carbohydrates, microbes use the ammonia to
