This calculator provides an approximation of ammonia emission based upon currently available information from USDA NRCS Agricultural Waste Management Field Handbook and LPES Lesson 21: Manure Storage Structures.
This calculator estimates of whole-farm ammonia emissions suggest that as much as 35% of the total ammonia emissions may occur during land application of manure depending on manure characteristics and environmental conditions.
This software helps producers make manure nutrient decisions based on livestock operation, storage capacity, application equipment, landbase, soil test results and crop selection.
This calculator determines the amount of carbon source material and water needed to create a good compost mix. The calculator is primarily intended for manure composting, however it can be used for other materials as well.
The Transportation Calculator can be used to determine the net impact of using (transporting and applying) manure or chemical fertilizer as a nutrient source in selected fields under different rotational systems.
This calculator compares the costs, on a dry matter basis, of: pit silage, bagged silage, bale silage, and dry hay. It calculates the costs from a standing crop to animal-ready product in the yard, factoring in standing crop value, equipment costs as well as field and storage losses.
This calculator is intended to assist producers to determine whether creep feeding will be economically beneficial to the operation. Often, the decision is based solely on "the weight gain" expected. This calculator will show the economic gain expected.
