Some Physical Properties of Four Manure Types Sold in Prachinburi

Some physical properties of four types of manure: laying chicken manure, broiler manure, beef cattle manure, and daily* cattle manure, have been studied. Each type of manure was prepared at four levels of moisture content i.e.. 10. 20. 30. and 40%wb. The results showed that: the appearance bulk density tends to increase with increasing moisture content. The angle of friction was independent of moisture content on all surfaces. The angle of repose of all manure varies significantly with moisture content. The centrifugal dispersion behaviour of each type of manure was different, but the distribution pattern of the same type of manure was not different when the moisture level was increased.
