Recyclable material is sold to wholesalers and organic material is composted and then sold in the market.
The cover crop is periodically clipped and composted in situ.
Like sulphur-coated urea, composted dairy manure and poultry litter are considered slow release fertilizers.
During that time period, the ammonium loss from sulphur-coated urea was significantly greater than that measured from the composted dairy manure.
The ammonium transported in runoff from the composted dairy manure was somewhat consistent for the 10-week study.
Treatments include ammonium nitrate (closed circles), sulphur-coated urea (open circles), composted dairy manure (closed triangles), and poultry litter (open triangles).
The possible contribution of a composting inoculum on decomposition and nutrient content was evaluated by subjecting the mixtures to inoculation.
Samples were collected from each treatment at 4-week intervals from the start of the composting process until 16 weeks.
