Catalogue: GRDC Final Reports
Plants sown into H2-treated soil accumulated 10-30% more shoot biomass and grain yield than plants grown in untreated soil... Calculations based on project field measurements of H2 emissions from nodules formed by HUP- rhizobial strains suggested the release of H2 into soil was equivalent to 150,000-225,000 litres per hectare over the life of legume crops fixing 125-200kgN/ha under Australian conditions... Based on the nodule load (0.25g dry weight/plant), rate of H2 evolution measured in the field and plant population, it was calculated that 225,000L of H2/ha was released into the soil over the life of the USDA442 HUP- soybean crop...
