Table grapes
Table grape world production remains steady at 25.7 million metric tons (MT), with China the largest producer and consumer. Australia’s warm, dry summers and rich soils provide an excellent environment for growers to produce world-class table grapes.
Specific considerations for table grapes
While table grapes have many of the same characteristics and needs of wine grapes, they do require additional applications of potassium and potentially magnesium to support fruit growth, fruit colour, and sugar assimilation.
While these can be fertigated there is also the option to apply nutrients through foliar applications in conjunction with natural chelators that improve vine uptake and translocation.
BioAg’s range of foliar biostimulants provide natural chelating agents, as well as key nutrients, vitamins, and enzymes to support plant growth, fruit set and fruit development.
The BioAg approach
BioAg nutrition programs are incorporated into a growers current nutrition program. Our objective is to make fertiliser and other inputs work better and build and support healthy and balanced soils and plants. Programs are custom-made for each block, using advanced soil and tissue analysis. These integrated programs typically incorporate a range of BioAg solid and liquid nutrients, often associated with conventional inputs. BioAg fertility programs can be developed to meet organic certification requirements.
Soil test
An experienced and Fertcare accredited BioAg agronomist works with you and provides technical expertise on your crop. If you don’t already have recent soil test data, we arrange a soil test for you. The results provide essential information about the soil fertility and soil structure for better performance. Download the BioAg soil sampling procedure here.
A tailored program
Based on the results of soil tests, crop requirements and other factors such as soil structure, climate, history of the block, and targets that you are trying to achieve, we provide a tailored program that aims to improve soil fertility and maximise yield response. We support you through the program to ensure that inputs are applied at the right time, in the right way.
Leaf and tissue testing
Any nutritional program cannot foresee the changes in weather, disease, or pests, that may impact a crop. During the season, growers may observe issues or evidence of stress in their crop. This may be due to greater growth or yields than planned, a trace element shortage or abiotic stresses. An on-farm inspection and associated leaf or tissue tests will promptly identify any issues, which can quickly be addressed by applying the appropriate inputs.

High yielding crops require fertile balanced soils
Key to highly productive crops is the function of soils. Soil structure, chemistry and biology are critical in supporting crops throughout the growing season. By improving all aspects of the soil, crops will benefit from improved access to moisture, due to improved infiltration and water holding capacity, improved access to nutrition through improved nutrient cycling, fixation (for N) and a reduction in loss pathways, improved resilience to abiotic stresses and disease, improved root growth providing access to additional moisture and nutrients as well as improved carbon sequestration and a range of other benefits (click for more on soil health).
Beneficial microorganisms stimulate the plant’s root growth and help protect it from abiotic stresses. This is made possible through mutually beneficial relationships that microbes develop with plants, for example mycorrhizal associations. BioAg products programs supply essential macronutrients (N, P, K, S, Ca), trace elements (B, Zn, Cu etc.), microbial food and metabolites beneficial microorganisms that colonise root systems, improving soil function, plant health and productivity.
Table grapes – key features of a BioAg program
The following table illustrates the cropping process and potential solutions depending on soil test results and other contributing factors. Call your BioAg Area Manager to discuss your individual needs.
Table grape resources
- 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.
- Biostimulants to the rescue – enhancing fertiliser efficiency
Nitrogen Use Efficiency (NUE) is the term used to describe the effectiveness of nitrogen uptake by plants, whether it be nitrogen latent in the soil, sequestered from the air, or applied as fertiliser.
