78 "We see that, from the second piece cut six times, deficiency in weight is made up for by superior quality. It contains 7. 12 Ibs. Of nitrogen, 8. 01 Ibs. Of phosphoric acid, and 1. 78 Ibs. Of potash more than the first crop. It is lower in percentage of lime and magnesia, which, however, are but of secondary importance for feeding purposes. It is certain then that cattle grazed on the crop of the piece cut six times would have been better nourished CARE OF PASTURES. 261 than those to which ...the hay from the first piece would have been given.
"Land used for pasture yields more nourishment than that where the grass is mowed off. Young shoots are much more nitrogenous than plants in flower and young green plants are more digestible than dried ones. In pastures the droppings of animals enrich the soil.
' " Aftermaths are richer in nitrogen than first cuts, and they are more nitrogenous the younger they are gathered ; they are richer, also, in phosphoric acid and potash. Theoretically, after- maths constitute a better food than first cuts, yet they sell at a lower price, probably owing to their appearance, and because when dried they are more indigestible.
