Organic production requires a range of certified inputs that will enhance soil fertility and target improved nutrient delivery to vines, to improve plant resilience to stresses, as well as increasing yield and quality. A key part of any BioAg program is to build and maintain available nutrients.
Specific considerations for organic table and wine grapes
In an organic system, BioAg is able to supply the majority of macro and micronutrients. The exception is nitrogen, which is typically applied in significant amounts, in a non organic system.
In an organic system the nutrition program will incorporate a range of products as sources of nitrogen including compost, manures, and fish emulsion, all of which contain nitrogen, as well as labile carbon. Improving soil labile carbon is critical in an organic system, as soil carbon is required for fixing of nitrogen by soil microbes from the atmosphere, and cycling nitrogen to plant available forms.
BioAg provides a range of biostimulants that are a source of labile carbon as well as metabolites, carbohydrates, enzymes, and vitamins. These not only directly support and stimulate vine growth stages but act as food sources to beneficial microbial populations.
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.
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.
