Energy Vs. Productivity: Diminishing Returns
MOSAIC, 6, 3, 9-12, May/Jun 75
Energy invested in corn production is compared with food energy returned in calculations by David Pimentel at Cornell University. The rate of return is falling off sharply in this already energy-intensive agriculture. Increased energy input, in the form of fertilizer, would yield far greater returns where agriculture is less sophisticated. (Author/BT)
