N, P and K applied in FYM to Hoosfield 1967-2019
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.
Total concentration of nitrogen in FYM determined in fresh sample (not dried) at normal moisture content by Kjeldahl digestion. Total carbon determined by combustion in oven-dry samples. Total P, K, Ca, Mg, Na, S and trace elements determined in oven-dry samples by digestion with 6M HCl, the extracts analysed by ICP-OES.
Rapeseed cake was applied to Series C 1852-1940, and replaced by castor bean meal, 1941-1967.
Two samples, A and B, were taken of the FYM applied each year, from the front and back of the trailer containing the FYM.
Trace elements (Fe, Mn, Zn, Cu, Ni, Co, Cd, Cr and Pb) were measured on FYM samples applied for the 1982 and 1983 harvest years. Two replicate samples (1 and 2) were taken from each sample for analysis.
