But on cash crop farms, forages are

But on cash crop farms, forages are often regarded as a crop of yesterday's agriculture. What value can be placed on forages in a rotation? Could additional nitrogen be economically applied to compensate for a lack of rotation? Experiments in Ontario showed a greater grain corn yield following a legume-grass crop than where corn was grown after cereal grain or corn under three fertility regimes (Table 14-5). On the loams and silt loams, additional nitrogen did not increase yields where the previous crop had been a legume-grass sod. On the finer textured clay loam and clay soils, additional fertilizer resulted in a yield increase, but at the levels applied was insufficient to reach the yield level obtained with corn following he legume-grass sod.
