OF WILD WHITE CLOVER
Wild white clover was sown on the surface in early spring at the
rate of I pound of seed to the acre
of the superiority of the New York variety, farmers in the State have been advised to harvest supplies of seed. A considerable amount has been produced in Albany County.
Yellow trefoil, although less valuable than wild white clover and birdsfoot trefoil, is a useful constituent of many New York pastures. It maintains itself in the pasture sward by seeding profusely even under close grazing conditions.
If the nitrogen required by New York pastures is not supplied through pasture legumes, the only alternative is to use fertilizers containing nitrogen or to make applications of manure. It is only under very exceptional circumstances that the high cost of the annual applications of nitrogenous fertilizers required when insufficient legumes are available, can be justified under New York conditions.
The need for manure
Applications of manure are especially beneficial to those pastures with thin swards that are on soils deficient in organic matter. Unfortunately, manure- discourages stock from grazing pasture herbage, and unless precautions are taken more harm than good may result. In order to use manure to advantage, light dressings of from 8 to 10 tons to the acre should be applied in the fall to the whole of one field rather than to part
