Extract

Field experiments were done at Rothamsted each year from 1940 to 1948 to compare arange of organic manures with farmyard manure and with fertilizers. Eight kinds of farmyard manure (FYM) made under controlled conditions from the same quantity of feedingstuffs, sewage sludges from 7 sources, composts of sewage sludge with straw from 4 sources, 5 types of town refuse, cut-bracken stacked over winter, and peat, were tested on potatoes at single and double dressings. All organic manures were compared with and without fertilizers supplying 0.6 cwt. N, 0.6 cwt.P2O5and 1.0 cwt. K2O. The soils were heavy loams, farmed in normal rotations; a fresh field was used each year. Residual effects were measured on cereals grown in the year after the potatoes.
