For instance, 10 tons per acre on "marginal" lands is unlikely, even with the best hybrids available. But using those lands is a good way to avoid competing with food supply production. <BR/><BR/>Then how do you do it? Same approach you use for crops, increased nutrient input. Poplars will grow well even in marginal lands, but you have to up the fertilizer and water supply to get a respectable result.<BR/><BR/>An alternative to hybrid poplar that may do well on marginal lands with less nutrient and water input is a plant that's better adapted to such an environment, switch grass for instance. You may get less ethanol per acre, but your inputs per ethanol gallons produced could be significantly lower. And there are a lot of "marginal" acres out there that could be used.KVMAPRhttps://www.blogger.com/profile/10185689536019289766noreply@blogger.com
