PRODUCTION OF HAY.
MANURE AND PHOSPHATE.
Dung is an excellent manure for hay production. It supplies , nitrogen and potash in sufficient quantities, but is relatively poor in phosphoric acid. Consequently it tends to produce quantity rather than quality. This can be remedied by supplementing the manure with a separate dressing of basic slag or finely ground rock phosphate, theso manures encouraging clovers and finer grasses. A further effect of dung on pass land is the production of early grazing before shutting up for hay, the shelter provided by the surface dressing and the nitrogenous effect probably being responsible for Ellis. The British Journal of Agriculture says that an application of ten tons of dung together with basic slag providing about 1001b of phosphoric acid (from 6 to lOcwt according to grade), every three years, has been found satisfactory.
