Viticulture
Vines are resilient plants and can be grown in different soil conditions. For the highest yield potential, it is important to maintain the soil structure and nutrient balance, with optimal water conductivity.
A BioAg nutrition program for vines is targeted at eliminating any macro and micronutrient deficiencies as well as building or improving soils. For example, address any issues with waterlogging, compaction, infiltration, or nutrient cycling. By improving soil conditions and delivering a balanced nutrient supply, we aim to deliver higher grape yields of consistently high quality, improved colour classification for reds and the ability to reach target Baumes earlier.
Improved soil health provides greater support for vines against abiotic stresses and disease. Reducing dependence on fungicides and insecticides lowers the possibility of delayed harvesting, due to withholding periods. Improving soil parameters such as compaction and infiltration extends irrigation intervals, while water use efficiency will be improved due to the greater root mass.

- Navigating Phosphate Prices
As we approach the end of 2025, phosphate prices remain stubbornly high — and many in agriculture are asking why. The answer lies in a mix of global demand shifts, supply chain changes, and local challenges that have reshaped the fertiliser market.
- A critical time to address nutrient deficiencies
As fruit and nuts near maturity and harvest, the critical processes for perennial tree crops and vines are the accumulation of sugars, the maintenance of the sugar-to-acid ratio, and the development of colour, and for vines, an increase in anthocyanins (dark pigments).
- Biostimulants increase yield
For the past four years, BioAg Agronomist and Area Manager Pete Emerson has been conducting a large-scale biostimulants demonstration with a grower near Brocklesby, southern NSW. The innovative grower is keen to explore ways to combat soil constraints and improve crop y...
- Soil-nutrient relationships
Nutrients, such as calcium and magnesium, may be supplied to plants solely from reserves held in the soil. Others like phosphorus and nitrogen are added regularly to soils as fertiliser to be withdrawn as needed by crops.
