Combating subsoil acidity for sustainable production through managing plant cation-anion uptake. At least 50 million hectares of topsoil and 23 million ha of subsoil of Australian land are presently affected by acidity, with this area expanding due to the ongoing processes of acidification. Surface liming is ineffective in neutralizing subsoil acidity. The project will develop an innovative method that stimulates root proliferation and ameliorates subsoil acidity through manipulating the balance ....Combating subsoil acidity for sustainable production through managing plant cation-anion uptake. At least 50 million hectares of topsoil and 23 million ha of subsoil of Australian land are presently affected by acidity, with this area expanding due to the ongoing processes of acidification. Surface liming is ineffective in neutralizing subsoil acidity. The project will develop an innovative method that stimulates root proliferation and ameliorates subsoil acidity through manipulating the balance of nutrient uptake by plants. The effects of the developed method on nutrient use efficiency and leaching loss, and crop yields will be quantified under different soil types and climatic conditions.Read moreRead less
Improving crops from the ground up: genetic solutions to optimise roots. This project aims to develop future crops with optimised root systems by overcoming genetic constraints that currently restrict their potential. Exploiting advances in genomics, transcriptomics, epigenomics and genome editing, this project expects to advance understanding of the biology and genetic controls of root development and responses to concurrent stressors, including drought, nutrient deficiency and soil-borne disea ....Improving crops from the ground up: genetic solutions to optimise roots. This project aims to develop future crops with optimised root systems by overcoming genetic constraints that currently restrict their potential. Exploiting advances in genomics, transcriptomics, epigenomics and genome editing, this project expects to advance understanding of the biology and genetic controls of root development and responses to concurrent stressors, including drought, nutrient deficiency and soil-borne disease. It is anticipated that project outcomes will support the development of crops equipped with novel root traits, enhancing resource-use efficiency and yield stability amid climate variability. This globally relevant research is designed to benefit the sustainability and profitability of the Australian grains industry.Read moreRead less
