Hazelnut crop

Australian production of hazelnuts is experiencing an increase as new orchards begin producing commercial quantities. The industry is well supported by research leading to improved, more efficient and sustainable production systems. (Australian Tree Nut Industry)

Special considerations for hazelnuts

As hazelnuts flower in winter, it is important to support post harvest recovery by ensuring soil nutrition is adequate, and soils are supporting nutrient cycling and uptake.

Replenishment of key macro and micronutrients post harvest, in combination with any required ameliorants for soil conditioning or improvement, along with a biostimulant to enhance nutrient uptake, ensures nutrients and energy reserves are replenished prior to flowering.

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.

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 (link to resources - 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.
