Maize

Maize is a multipurpose, valuable rotation crop with a multitude of varieties available. The crop has a low capital investment, low growing risk, and generally a longer window of harvest than other crops, making it the third most important cereal crop species in the world (after wheat and rice).

Specific Considerations for Maize

Crop biomass is critical for delivering high yielding, high quality maize, as either forage or kernel production. To support optimal growth consideration of soil parameters, water infiltration, drainage, and nutrient cycling and supply will ensure maize crops are supported through the season.

Utilising a sustained release form of phosphate fertiliser, in conjunction with starter fertilisers, will ensure the presence of critical nutrients through the lifecycle of the crop. The addition of biostimulants supports soil function such as agglomeration (aiding water infiltration and drainage), and nutrient cycling delivery.

Use of biostimulants at stem elongation enhances and supports vegetative growth, while use at flowering provides essential nutrients, vitamins, and metabolites.

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.

Maize – 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.

Planning
Objective
Growers to have a plan in place for the cropping season, that takes into account the specific nature and long term objective of their soils and farming practice.
Activity
Book a soil test and consultation with your local BioAg Representative.
BioAg Product
Prior to sowing
Objective
Provide optimal soil conditions and nutrition to support crops. Prepare soils for the period of the rotation addressing soil structure, chemistry (eg pH) and nutrition. Incorporate BioAgPhos which enables a reduction in the use of chemical starter fertiliser which can reduce emergence.
Activity
When applied, ameliorantes support crops through the entire season, by including sustained release phosphate at a rate based on soil phosphate levels, depending on the needs of your crop.

At sowing
Objective
Provide the essential nutrition and food sources to promote emergence and early plant growth and vigour, critical in the development of stronger, more resilient crops.
Activity
Include a soil biostimulant with starter fertiliser to increase soil organic carbon and important microbial food sources and metabolites to improve nutrient access and minimise nutrient losses.
BioAg Product
Soil & Seed: 6 – 8L/ha as a seed inoculant or preferably diluted and applied to soil
Eearly growth stage
Objective
Apply additional key nutrients to deliver optimal growth.
Activity
Include a soil biostimulant with trace elements and additional nitrogen to enhance nutrient cycling and delivery to the crop.
