Agronomy | BioNutrition

BioNutrition is more than selecting a fertiliser.

Get ready to take your turfgrass surfaces to the next level with BioNutrition! Our innovative approach combines mineral fertilisers with nutrients from biological sources to nourish and enhance growth. Each turfgrass surface has differing nutrition requirements but all high quality turfgrass surfaces depends on three conditions:

The correct rootzone environment for the turfgrass species being managed
Balanced and optimised plant nutrition
Active interaction between soil microbes and plant roots

We harness the power of beneficial microorganisms, organic compounds, and natural

minerals to promote a more sustainable and environmentally friendly method of

turfgrass management. With SW Agronomy, you can achieve your goals with the

"three Rs" principle:

the Right practice
at the Right time, and
in the Rght place.

This is achieved by implementing BioNutrition for Turfgrass Surfaces.

What is meant by "Turfgrass Stress"?

"Turfgrass stress"is a term that's commonly used when the turfgrass surface doesn't look quite right. But, there are so many factors that can cause stress, such as high or low temperatures, pest and disease attacks, wear from use, and high or low light intensity. What is not commonly understood is that, most of the time, stress is caused by an interruption to the vital process of photosynthesis.

Photosynthesis is the conversion of sunlight into chemical energy to drive the reactions that create carbohydrates used as the fuel for all plant growth processes. Factors that interrupt the electron transport train (ETC) result in oxygen molecules leaving the ETC and become highly charged and interfere with energy producing reactions. Little or no carbohydrates are produced for fuel and is expressed in plant stress symptoms, e.g. weak growth, slow recovery from damage, loss of colour and ingress of disease.

BioNutrition helps the plant to increase the production of anti-oxideants that help the plant to withstand these stress factors, helping your Turgfrass Manager to keep preparing great playing surfaces.

Correct Rootzone Environment and Nutrients that feed the Soil & Plant Biology

SW Agronomy advise on fertiliser programmes to achieve desired outcomes, using nutrients that are harvested from sustainable resources and put BioNutrition into practice.

Precision Guesswork has no place in high quaity turfgrass management! We provide a quick, on-site assessment using a BRIX refractometer followed by a detailed analysis of rootzone nutrients. Our RZ Analysis supplies the information to ammend the rootzone to provide the grass plant with the best conditions for growth and vigour that help the turfgrass manager prepare high quality playing surfaces.

Many people think that science is exact, but the reality is that interpretation of multiple sources of data is the key to making successful outcomes. We carry out a comprehensive nutrient analysis that uses four different analytical methods and interpretations rather than being slaves to numbers or a particular method. We take a broad view of the nutrient content and match the results to the clients requirements.

Encouraging the interaction between the rootzone and turfgrass plant roots

Figure from Microorganisms 6 (3): 95. (2018).

SW Agronomy, have spent many years investigating the interaction between rootzone microbes and the turfgrass plant root. One subject of study is the Rhizophagy Cycle in which microbes are "farmed" by plant roots, illustrated right:

Microbes enter the plant root carrying nutrients from the soil
Nutrients extracted from the microbes by Reactive Oxygen Species
Nutrient exhausted microbes stimulate root hair growth and leave the root through the tips
Microbes recharge with nutrients from the rootzone environment.

Giving the plant only soluble fertilisers results in plants not having to work for their nutrition, leading to few root hairs and weak processes vital for plant health and growth. Microbial and plant derived biostimulants increase root exudates that result in enhanced control of plant pathogens, and increases in nutrient availability and uptake by the roots, resulting in turfgrass plants that are able to withstand environmental stresses.
