Choice of cereal and pulse species and varities

All the main cereal crops - wheat, barley and oats, triticale, rye and spelt - can be grown organically in the UK. Until recently, the most important organic cereals were wheat and oats, with premiums paid for samples which reached milling quality. In the last year or two, more livestock farmers than arable farmers have converted to organic production so that feed grain has been in short supply, and the range of cereals grown organically has increased. New markets have also developed. Malted organic barley has been used for some time to produce beer, and now barley malt and wheat have been processed into organic whisky

EuFe2_2As2_2 under high pressure: an antiferromagnetic bulk superconductor

We report the ac magnetic susceptibility $\chi_{ac}$ and resistivity $\rho$ measurements of EuFe$_2$As$_2$ under high pressure $P$. By observing nearly 100% superconducting shielding and zero resistivity at $P$ = 28 kbar, we establish that $P$-induced superconductivity occurs at $T_c \sim$~30 K in EuFe$_2$As$_2$. $\rho$ shows an anomalous nearly linear temperature dependence from room temperature down to $T_c$ at the same $P$. $\chi_{ac}$ indicates that an antiferromagnetic order of Eu$^{2+}$ moments with $T_N \sim$~20 K persists in the superconducting phase. The temperature dependence of the upper critical field is also determined.Comment: To appear in J. Phys. Soc. Jpn., Vol. 78 No.
