Using the methods described in Part I, an experimental study was made of the changes in composition and of the losses of organic matter and nitrogen from deep litter in a manner similar to the study made on composts and described in Part II. Over a period of 11 months, losses of organic matter and of nitrogen by decomposition were approx. 50 and 40%, respectively. Results indicated that deep litter should be moistened before storage to prevent escape of ammonia and encourage formation of nitrate. Indirect calculations of the losses of organic matter and nitrogen throughout the experimental period were made from the changes in the ratios of each to the ash, the phosphorus and the potassium contents, assuming that these three components of the straw and droppings accumulated in the litter without loss.
