Organic pastures

At BioAg we work with our clients to develop tailored and sustainable nutritional strategies for their organic pasture systems. Nutrition plans are formulated taking into account peak feed requirements, calving periods, feed quality requirements, and available resources.

Features and Benefits

  1. Proven techniques for growing organic pasture
  2. Stimulate growth during colder months
  3. Increase soil fertility for this season and the next

Specific considerations for organic pasture

In an organic system there is limited access to nitrogen fertiliser to promote growth. In pasture systems this can be offset to a large extent through pasture composition (use of clover as a nitrogen fixer), and building soil carbon, which will aid nitrogen fixation from the atmosphere.

For peak demand, or in fodder crops, nitrogen can be supplied through one or more of compost, manures, and fish emulsion, all of which contain nitrogen as well as carbon. BioAg’s HydraFish®, in combination with Balance & Grow Organic®, is an ideal growth promoter for pastures and crops.

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.

  • 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.
