Extract

Several town-refuse manures were compared with farmyard manure at Rothamsted and five other places between 1940 and 1947. The organic manures were used at 8 and 16 tons/acre with and without fertilizer nitrogen and potash. Direct and residual effects were measured on agricultural and horticultural crops.

All organic manures improved yields in the year of application, FYM most and consistently. The average percentage increases in yield produced by the pulverized refuses tested, in relation to the increase from an equal weight of FYM, were: sugar beet 22, mangolds 83, carrots, 85, potatoes 51. The corresponding figures for screened dust were: sugar beet 40, mangolds 28, carrots 41; the dust slightly depressed potato yields. Averaging all sixteen experiments on root crops, the pulverized refuses had 64% of the first-year effect of FYM and the screened dust 25%.
