The effect of farmyard manure on fertilizer responses [PDF]
The Journal of Agricultural Science, 1959 Farmyard manure affected the response of the potato crop to fertilizers similarly in seven series of experiments (sixty-two in all) at Rothamsted, and in the West Midlands and north of England.In the absence of f.y.m. there were large interactions between each of the fertilizer nutrients, but with f.y.m. the interactions were small.

The changes taking place during the storage of farmyard manure. [PDF]
The Journal of Agricultural Science, 1917 We can now bring together the various results obtained during the course of our investigations.We find that the changes are at a minimum underanaerobicconditions, and they are as follows:1. In the laboratory experiments as much as 17 % of the dry matter may be converted into gas: in the heap the proportion is less.2.

Does long-term farmyard manure fertilization affect short-term nitrogen mineralization from farmyard manure? [PDF]
Biology and Fertility of Soils, 2009 One of the challenges in organic farming systems is to match nitrogen (N) mineralization from organic fertilizers and crop demand for N. The mineralization rate of organic N is mainly determined by the chemical composition of the organic matter being decomposed and the activity of the soil microflora.
