Strategies for mitigating frost damage in the Upper North region (UNF1724)

Frost events have been a significant concern in the Upper North region, resulting in substantial crop losses and economic impacts in previous years. The Upper North is susceptible to frost damage at various stages in the growing season, leading to decreased yields. Therefore, a holistic approach applying proven research outcomes over numerous years will be trialled in local validation trials and extended through this project. This project is a co-investment, with GRDC providing 50% of the total funding.

Making the most of phosphorus(P) fertiliser inputs: Managing spatial variability and long-term strategies (TCO6024)

The overall aim of this project is to increase the profitability from phosphorus (P) fertiliser applications and determine sustainable P fertiliser strategies. This project focuses on two key P management areas: improving applications in variable paddocks/landscapes and refining long-term P management strategies on highly P responsive soils. This project will build on the results from SAGIT projects TC219 and TC221. This project is a co-investment, with GRDC providing 50% of the total funding.

Appropriate fertiliser strategies for on-row lentil sowing in saline soils (CAS5724)

This project aims to determine the residual benefit of on-row and off-row sowing and appropriate fertiliser strategies for sensitive lentil crops in phosphorus deficient and moderately saline calcareous soil types of Yorke Peninsula. Research will investigate management techniques of utilising residual phosphorous in a cereal phase along with phosphorous placement at seeding to optimise lentil grain yields and economic returns. This project is a co-investment, with GRDC providing 50% of the total funding.

Pesticide effects on soil microbial functions in contrasting SA soils (USA3323)

The aim of this project is to understand how soil properties influence the effects of pesticides on soil health. The project team will assess six targeted pesticides in 10 contrasting South Australian broadacre cropping soils. This knowledge will deliver farmers essential information for identifying the best pesticide-soil combinations to maintain healthy soil microbial communities.
