Dr Yash Dang is Senior Research Fellow at The University of Queensland possess extensive experience in soil and nutrient management. He is currently leading a national project on costs of edaphic stresses to the Australian grains industry. He is also leading the northern grains region in national GRDC projects to identify and manage soil constraints, conservation agriculture, strategic tillage and sustainable land management practices. While his research spans in the areas of crop production, much of his research focuses on soil constraints. He has also coordinated soil carbon and soil quality projects in Queensland cropping soils. Yash has great faith in engagement with the farmers to develop collaborative, participatory research project to address soil health issues. He also has strong interest in proximal and remote sensing to identify constraints at farm and national scales for site-specific soil and nutrient management.

Research Interests

  • Identification and management of soil constraints
    Soil salinity, sodicity, acidity, and alkalinity, elemental toxicities such as boron, chloride and aluminium and compaction are important soil constraints to agricultural sustainability in many soils of Australia. Estimating the severity of soil constraints, and their impact on plant productivity and management is a very complex issue. Several soil properties in the surface and subsoil interact with each other to determine the local environment for root growth at a given time. Rarely do the various soil stresses occur independently. Moreover, variable distribution of soil constraints, both spatially within a paddock, across the landscape and with depth in the soil profile, and the complex interactions that exist among the various physio-chemical constraints, make it difficult to determine which stress is the major limitation to crop production. Grains Research Development Corporation projects are helping growers identify soil constraints using proximal sensing and remote sensing and manage soil constraints through amelioration, crops and cultivars adaptation and/or matching inputs to the realistic potential yield in the presence of soil constraints.
  • Conservation agriculture for sustainable crop production and land management
    No-tillage (NT), stubble retention (SR) and crop rotation component of conservation farming systems offer a wide range of economic, environmental and social advantages compared to conventional tillage (CT) which involves intensive disturbance of soils prior to crop sowing. Hermitage long-term NT- SR experiment initiated in 1968 is the longest continuing trial in Australia. The project quantify the impact of continuous NT-SR and nitrogen on productivity, profitability and soil health.
  • Strategic tillage in no-till farming systems
    Adoption of no-till (NT) has progressed steadily, there are still situations and attitudes that hinder adoption of what are seen as rigid systems. These concerns have been enhanced by the emergence of five major issues in long term NT systems - (i) build-up of soil- and stubble-borne diseases; (ii) build-up of herbicide-resistant weeds; (iii) nutrient stratification in the surface soil; (iv) build-up of soil insect; and (v) environment and health concerns about the effects of herbicides on- and off-site. An occasional strategic tillage (ST) has been used as a means to manage some of the specific issues emerging in NT farming systems. However, growers who practise strict NT systems are concerned that even one-time tillage operation may undo much of the positive effect of NT farming systems on soil conditions. Those promoting ideas of strictly no soil disturbance predict irreparable damage to soil from occasional ST. The industry driven project identify (i) the need for ST in NT farming systems; (ii) strategies for the safe implementation of ST in NT systems, and (iii) the potential risks and rewards of occasional ST on agronomic outcomes, soil health and the environment.
