BioNutrition for Turfgrass Surfaces

BioNutrition Products

To back up our expert advisory service, South West Agronomy produce and supply a small range of specialist treatments, which are the tools that make BioNutrition work. After paying for our advice we find that clients often purchase low quality products to implement our recommendations. See below some of our unique treatments that guarantee our advice.

PAR+

Photosynthesis is the key to healthy turfgrass playing surfaces. The dull misty days of autumn and winter, however, results in great reduction of photosynthesis in the turfgrass plant, which seriously affects the ability to resist disease and to recover from wear resulting in poor playing surfaces.

Shade can lead to a huge reduction in photosynthesis in sports stadia and golf courses with tree lined fairways and close to greens.

PAR+ contains 5-aminolevulinic acid (5-ALA), which boosts light absorption and energy conversion in photosynthesis. 5-ALA also improves stress tolerance by activating antioxidant enzymes and protecting photosystem II from oxidative

damage, which helps plants endure the low light conditons of autumn and winter, and

reduces the impact of direct shade.

Application Rates

The dilution rate of PAR+ varies depending on several factors, including turfgrass

species, environmental conditions, and the specific stress factors involved (e.g., mowing,

drought, compaction). Guidelines for the dilution rates are as follows:

1 litres of liquid or 300g of powder in 300 litres water per hectare (Lower range)

Effective for routine maintenance and mild stress conditions.

Enhances photosynthesis, root growth, and microbial activity without overwhelming the system. Suitable for frequent applications, such as bi-weekly or monthly during the growing season.

1.5 litres of liquid or 450g of powder in 300 litres water per hectare (Moderate range)

Useful when turfgrass is experiencing moderate stress, such as frequent mowing, mild drought, or nutrient deficiency. Supports stronger root growth and more robust microbial communities by maintaining a higher level of root exudation. Can be applied every 2-4 weeks, depending on turfgrass health and environmental conditions.

2 - 3 litres of liquid or 600-900g of powder in 300 litres water per hectare (Higher range)

Recommended for more severe stress conditions, such as prolonged drought, compaction, or heavy wear. Boosts the plant's antioxidant production and stress tolerance, helping it better sustain microbial communities. Typically applied less frequently (monthly or every 6 weeks), as higher concentrations provide a longer-lasting effect.

Considerations for Optimizing PAR+ Application

Application Frequency: Lower concentrations (1L or 300g per Ha) can be applied more frequently, while higher concentrations (2-3 litres or 600-900g per Ha) should be used less often to prevent over-stimulation.
Environmental Factors: In warmer climates or during active growth phases, slightly higher concentrations (1.5-2 litres or 450-600g per Ha) may be needed, while cooler climates may benefit from lower rates (1 litre or 300g per Ha).
Turfgrass Species: Some turfgrass species may have different tolerances to PAR+. For example, cool-season grasses (e.g., bentgrass or fescue) might require lower concentrations than warm-season grasses (e.g., Bermuda or zoysia) due to differences in growth rates and stress tolerance.

Lignase

Lignase is a complex blend of enzymes and bio additives that stimulate enzyme activity to break the strong lignin bonds that are resistant to degradation.

Turfgrass thatch is composed of various organic components, with lignin (15% to 30%), cellulose (20% to 40%), and hemicellulose (10% to 30%) being the primary structural constituents. Soil microbes degrade organic matter to access nutrients but lignin is held together with strong chemical bonds that restricts the bioavailability of other, more degradable, components of the plant cell wall such as cellulose and semi-cellolose.

Microbial products can result in a reduction of thatch in turfgrass surfaces, but lignin still requires removal through

expensive and time-consuming mechanical operations and heavy applications of sand to 'dilute' the thatch. The organic matter is still there but buried in sand! How can applying 200-300 tonnes of sand be called sustainable?

In contrast, Lignase is an easy to apply liquid formulation that works unseen under the surface breaking down lignin without disturbing the playing surface nor damaging the turfgrass plant. Lignase reduces destructive and costly mechanical methods, such as scarifying and hollow coring. Plant tissue damaged by these physical operations leads to disease that incurs more costs to control, and revenue is lost during the thatch control operations and playing surface recovery phases.

Apply Lignase from end April to end September, when soil temperature are +10C, and no more than six applications per year.

Dilute1 litre in 300 litres of water per hectare every 4-6 weeks when ground conditions allow the use of spraying equipment.

LGL Pro

LGL Pro is a complete, true solution, liquid fertiliser that:

is proven to be safe for soil microbes
supplies all the required nutrients for healthy turfgrass growth
increases nutrient uptake and use

When using liquid fertilisers for your turfgrass surfaces, you need to know that you are not killing or changing the rootzone environment. Cheap liquid fertilisers cause huge swings in soil pH that microbes cannot survive but LGL Pro is fully buffered and is proven to help soil microbes to flourish.

LGL Pro contains all the nutrients required for healthy plant growth in a fully soluble form. Cheap supension fertilisers are not fully utilised by the plant and up to 55% of the fertiliser is lost through leaching. LGL Pro improves nutrient uptake and use by the plant, meaning lower rates of application and cost.

Apply LGL Pro at the required dilution for healthy turfgrass growth. You may need to experiment to find the 'sweet spot' for your turf, but start at 5 L/Ha and increase/decrease as required.
