Towards sustainable bioproduction systems: harnessing organic nitrogen for plant growth. It is of great concern that over 50% of nitrogen fertiliser applied to crops is lost to the environment, resulting in a large environmental footprint and greenhouse gas emission. Future farming systems have to reduce nitrogen fertiliser use but this threatens crop and biofuel production. Alternatives to man-made nitrogen fertilisers are crop residues and organic materials which are more stable in soils but l ....Towards sustainable bioproduction systems: harnessing organic nitrogen for plant growth. It is of great concern that over 50% of nitrogen fertiliser applied to crops is lost to the environment, resulting in a large environmental footprint and greenhouse gas emission. Future farming systems have to reduce nitrogen fertiliser use but this threatens crop and biofuel production. Alternatives to man-made nitrogen fertilisers are crop residues and organic materials which are more stable in soils but less available to plants. How plants can best access organic nitrogen will be explored, based on our recent discovery that plants can use protein as a nitrogen source for growth. The project will produce essential knowledge for nitrogen-efficient bioproduction.Read moreRead less
Tailoring nano-crystal suspensions for extended ion supply to hydrophobic and hydrophilic leaf surfaces. Nutrient deficiency undermines the potential of billions of people and many nations. The requirement is to rapidly increase micro-nutrient delivery to support intensive and fortified crop production. This proposal seeks to develop a controlled ion release system through the use of tailored suspensions of nano-crystal nutrient materials for delivery to plants through the leaves. This will incr ....Tailoring nano-crystal suspensions for extended ion supply to hydrophobic and hydrophilic leaf surfaces. Nutrient deficiency undermines the potential of billions of people and many nations. The requirement is to rapidly increase micro-nutrient delivery to support intensive and fortified crop production. This proposal seeks to develop a controlled ion release system through the use of tailored suspensions of nano-crystal nutrient materials for delivery to plants through the leaves. This will increase yields from arable land, reduce water requirements and fertiliser applications, fortifying foods for better nutrition leading to improved human health and wellbeing. It leverages and applies recent significant advances in surface science and nanotechnology to gain improved outcomes in agriculture.Read moreRead less
