Carbon Dots Enhance Bioavailability of Nitrogen in Soybean Crops: acsnano soybeans soya agriculture agritech carbondots nanomaterials nanoscience
By Surbhi JainAug 16 2022Reviewed by Susha Cheriyedath, M.Sc. In an article recently published in the journal ACS Nano, researchers discussed the utility of carbon dots to increase nitrogen bioavailability to support soybean growth and nutritional quality under drought stress.
Soybean: A Crucial Commodity About 366 million tons of soybean are produced annually on a global scale. To increase soybeans' ability to withstand drought and retain their nutritional value, nitrogen usage needs to be increased. Despite being relatively new, nano-enabled agriculture is a field with both prospects and difficulties.
Due to the decent distribution of carbon ENMs in soil, previous investigations suggested that lower concentrations of the carbon ENMs could influence nitrogen fixation in legumes. The researchers postulated that carbon dots in soil could increase the ability of soybean to withstand drought and absorb nitrogen by controlling the rhizosphere exudates and microorganisms and boosting the nodules' capacity to fix nitrogen.
Despite a 50% decrease in soil moisture, the soil application of carbon dots increased soybean production by 25.2% and quality due to improved nitrogen bioavailability via regulation of the rhizosphere process and enhancement of nodule nitrogen fixation. The increase in nitrogen bioavailability in soybean offered a workable way to increase crop nitrogen use efficiency, which helped to reduce the overuse of nitrogen fertilizer and lessen environmental harm.
