Engineered clay-polysaccharide composites for efficient nutrient delivery

澳大利亚土壤中大多数可耕地作物的氮素养分利用效率较低，导致氮素的过量施用。氮的低利用效率主要是由于氮的淋失和气体排放造成的，这不仅给农业社区带来了经济负担，也造成了环境的恶化。该项目旨在与粘土工业合作开发具有控释特性的肥料产品，以提高氮的利用效率和农业生产力。它还将为使用粘土的采矿业创造新的市场机会，并为农化工业创造新的营养和水分输送材料，从而创造市场机会。

Nitrogen (N) nutrient use efficiency of most arable crops in Australian soils is low, leading to excessive application of this nutrient. The low N use efficiency is attributed to its loss through leaching and gaseous emission, which contributes to both economic burden of the farming community and also results in environmental degradation. This project aims to work with clay industries to develop fertiliser products with controlled release characteristics to increase N use efficiency and farm productivity. It will also create new market opportunities for the mining industry for the use of clays and create novel materials for delivery of nutrients and moisture for the agrochemical industry resulting in the creation of marketing opportunities.
