The core of our sorghum agronomy success has been through focusing our attention on improving soil health and soil structure. In sorghum and other broadacre crops, we have proven results in lifting productivity with the use of advanced soil bio-stimulants from Petrik Soil Technology.
These Petrik treatments
- maximise nutrient availability and uptake
- increase rooting depth
- improve water infiltration and soil moisture holding capacity
- stimulate resilience and yield increases.
Total Grower Services have extensive experience in addressing soil health limitations. The productivity gains we can get for farmers have whole system benefits.
- soil health
- soil structure
- soil biodiversity
Our integrated crop management approach means we use the latest technologies available: Petrik Bio-Stimulants, we use Bio Resources, Bugs for Bugs IPM and Soil Moisture Monitoring technologies. These are integrated with other macro and micro amendment requirements.
One of the biggest problems facing Australian Sorghum and broadacre farmers is soil compaction.
Compaction is often caused by:
- previous farm management practices or
- heavy trafficking following a wet harvest
The creation of stable humus by Petrik Soil Technology products loosens the soil and allows better rooting depth and increased water infiltration. By adding this advanced microbial complex to the soil, the soil macro and micro fauna populations return. (e.g. worms)
Petrik soil bio-stimulants are advanced inputs that help rebuild the biological balance. They have an excellent history of rapidly improving soil structure and thereby increasing the ability of sorghum crops to access the total available soil moisture and nutrient.
Water Penetration and Deeper Roots
Across the Australian Broadacre cropping belt where rainfall is often inconsistent, the increased water penetration and rooting depth has built greater crop resilience through the dryer months.
Often at planting we have good soil moisture as a result of fallowing, however if compaction layers limit the actual rooting depth of a crop, not all of the available soil moisture and nutrients are accessible to the plant.
The act in itself of allowing the sorghum roots to access the maximum depth of the soil profile, only further improves soil structure and water infiltration as the root systems of previous crops breakdown leaving an improved soil capillary network.
Improved Nutrient Uptake
Nutrient uptake is of key importance in sorghum and other broadacre crops. We have extensive experience and history of being able to increase this with these biological inputs.
The Petrik soil inoculants contain phosphorus solubilising microbes. These assist in releasing phosphorus which are locked up in the soil. Under good biological rotational farming systems high yielding crops are also routinely grown using less chemical nitrogen inputs. This in real terms translates to a reduction in the quantity of chemical fertilizer inputs required at planting.
