Olives

The Australian Olive Industry is worth an estimated $210 million. Olives flourish where there is good drainage and cool winters, with hot dry summers without humidity. In recent years there has been a focus on the role and management of healthy soils in producing healthy trees and lifting grove productivity.

Specific considerations for olives

Olive are robust and tolerant trees, able to withstand compacted soils and poor fertility. To increase yields and fruit quality balanced nutrition, well drained soils and soil fertility need to be addressed. 

Olives do not require a lot of nutrition compared to other tree crops however, a common issue is over use of nitrogen fertilisers at the expense of others. Use of sustained release fertilisers, such as BioAgPhos, as well as soil biostimulants to improve soil structure, nutrient retention and cycling, agglomeration, filtration and water holding capacity will benefit olives and buffer any oversupply of nutrients.

Nutrient deficiencies are often difficult to identify, the use of leaf tests will provide the most accurate information. Addressing macro or micronutrient deficiencies with foliar products, in conjunction with a foliar biostimulant, enhances uptake and translocation.

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.
