AB  - Details of the chemical composition of the organic manures applied to the Hoosfield Spring Barley Experiment, 1852-2019. Farmyard manure (FYM) is applied each autumn at 35t/ha to plot 72 since 1852, to plot 71 1852-1871 and to plot 73 since 2001, from cattle housed on cereal straw. Rapeseed cake or castor bean meal was applied to Series C from 1852-1967, to supply 48 kgN/ha .  FYM has been analysed routinely since 1967.  This dataset gives details of the chemical composition: % total N, C, P, K, Ca, Mg, Na and S, and the total amount of each element applied each year in FYM 1967-2019. There is also limited mean data for earlier periods and trace element data for 1982 and 1983, and N, P and K content of the rape cake/castor bean meal 1926-1967.  



The FYM supplies on average 236 kgN/ha, 47 kgP/ha and 304 kgK/ha; the rape cake/castor meal 57 kgN/ha, 10 kgP/ha and 11 kgK/ha. For comparison, the standard inorganic fertilizer treatments on Hoosfield receive 0-144 kgN/ha, 35 kgP/ha, and 90 kgK/ha.
