Abstract
Of grass cut for conservation, hay claims about 80 per cent. in Holland but—according to the findings of the 1961/62 surveys of fertilizer practice—more than 90 per cent. in England and Wales, against 10 per cent. or less as silage. With the farmer's habit of haymaking so firmly entrenched, in spite of attendant difficulties and huge losses of dry matter, an appraisal of the machines that are available for getting the crop is of value.
