What are bio-stimulants and is there a place for them in turf management?

Bio-stimulants, is a broad term that literally means a group of ingredients that stimulate life. Common commercial bio-stimulants contain many, if not all of the following major ingredients: humic substances, sea kelp extracts and plant hormones.

Humic substances are complex organic compounds that can generally be classified into humic acid, fulvic acid and humin. Many studies have shown positive responses to the application of humic substances. Shoot and root growth, seed germination and seedling establishment are usually reported as direct plant responses to humic substances.

Sea kelp extracts contain a large number of organic and mineral compounds. They are particularly rich in phytohormones, complex organic compounds, vitamins, simple and complex sugars, enzymes, proteins, and amino acids. Sea kelp extracts, also known as seaweed, are best known for their high concentration of cytokinins and auxins. In essence, the fact that biostimulants are manufactured and marketed as a complex mixture of ingredients, is indicative of the potential functions that they may play in turf management, with plant hormones and humates being the two most important components. Seaweed has been used as a fertiliser for many years. Applying seaweed extracts increase turf grass stress tolerance levels, this is of particular importance in golf courses and sports pitches, which receive large amounts or wear. The positive impact of seaweed extract application is mainly attributed to the complex mix of betaines within the liquid seaweed which raises the plants stress thresholds to higher levels. Compounds, such as betaines are thought to play a vital role in cytoplasmic adjustment in response to stress. Seaweed extracts can improve the water holding characteristics of soils

Plant hormones are grouped into 5 major categories. Auxins, Gibberellic acids, Cytokinins, Abscisis acids and Ethylene. Auxins promote root and shoot elongation, gibberellins promote shoot elongation, regulate seed germination and seedling establishment. Cytokinins are particularly implicated in cell division, morphogenesis, nutrient mobilisation and senescence delay. 

Is there an organic turf management product that will improve the quality of my soil?

Purity is a new completely organic soil conditioner made from plant extracts which is designed to purify the soil before the onset of spring growth and autumn/winter shutdown. The aim of this product is to provide the soil with a building block of organic matter, which will stimulate all available nutrients to release steadily over a 6-8 week period. It improves root mass, increases plant tolerance and acts as bio-stimulant, enhancing microbial activity.

What is compost tea and why is it used in sport and golf turf management?

Compost tea is the biological culture medium for disease suppression and nutrient maximisation. It adds and lifts the bio activity of beneficial fungi-bacteria-mycorrhizae and protozoa in the soil to compete and feed off the diseases that you may already have attacking your roots at present. When you apply so much good fungi and bacteria to your leaves and roots, the harmful ones find it difficult to find a place on the plant to attack.

Compost tea is a totally safe, biological, cost efficient turf management product. The good bacteria and fungi in ReviTEAlised can help with disease suppressions. It makes plants healthier and more resistant to attack from fungal diseases and reduces the need for conventional pesticides. It reduces nutrient leaching, improves water retention, cationic exchange, unlocks nutrients and stimulates root hairs for extended growth.

Is there an alternative to using expensive fungicides to combat fusarium in the autumn/ winter?

Yes, Ground Force Leisure recommends Liquid Iron applying ideally between September and December. The liquid iron hardens the sward and with the addition of citric acid it helps to prevent fusarium. The iron is taken up into the grass via leaves/roots, this provides good colour and disease resistance without excessive growth.

How can I keep good grass coverage on my tees in winter?

Ground Force Leisure recommends Johnson's J Tee because it contains the new unique 4turf tetraploid ryegrass. The benefits of the unique 4turf tetraploid ryegrass is that it establishes itself quickly under low temperatures on frequently worn turf, it has deeper rooting, improved drought tolerance and disease resistance.
