Sentences with phrase «increasing nitrogen fixation»

Hence, increasing nitrogen fixation could improve overall plant productivity for farmers who grow legumes in both industrial and developing countries while diminishing or eliminating the need for nitrogen fertilizers.

Elevated CO2 increases nitrogen fixation at the reproductive phase contributing to various yield responses of soybean cultivars.

Not exact matches

«We can increase carbon sequestering and nitrogen fixation, or give Azolla's properties to other plants.

Their analysis, which could discern human - derived nitrogen from natural nitrogen fixation, revealed that the oceanic nitrate concentration increased significantly over the last 30 years in surface waters of the North Pacific due largely to the enhanced deposition of nitrogen from the atmosphere.

Legumes are protein - rich and would provide relief for the deficit; they also increase the amount of nitrogen available to plants through biological nitrogen fixation, reducing the need for fertilisers.

Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

Furthermore, those yields will increase without the addition of soil N fertilizer, as the results of this study clearly show that it was a CO2 - induced stimulation of nitrogen - fixation by symbiotic bacteria that provided the nitrogen necessary to increase seed yields.»

Limited direct impacts of atmospheric CO2 on nitrogen - fixation have been found in soil biological crusts (Billings et al., 2003), but soil microbial activity beneath shrubs has been observed to increase, thus reducing plant - available nitrogen (Billings et al., 2002).
