Seaweed and how it benefits your turf

Seaweed, also known as macroalgae, has been used in agriculture for centuries and its benefits in greenkeeping have steadily gained greater recognition over the last few decades. Seaweed extracts have been found to improve turf quality, reduce stress, and enhance overall soil and plant health. Liquid Seaweed extracts are powerful biostimulants, providing a luxury of carbohydrates to boost the soil’s microbial populations. They are also used extensively as a food source for compost tea brewing due to their carbohydrate load.

An abundant and renewable resource that is rich in nutrients, trace elements, and plant growth hormones, seaweed It is a natural source of nitrogen, potassium, and phosphorus, all of which are essential for plant growth, seaweed should be a serious part of your greenkeeping regime. It contains cytokinins, auxins, and gibberellins, which are plant hormones known to promote cell division, elongation, and differentiation. These plant growth regulators help improve the quality of turf by increasing shoot and root growth, enhancing photosynthesis, and reducing stress.

One of the main benefits of using seaweed in fine turf management is its ability to reduce stress. Bowling green turf is often exposed to environmental stressors such as water-logging, cold, heat, drought, and disease. Seaweed extracts have been found to increase the tolerance of fine turf to these stressors by improving water use efficiency and enhancing the plant’s defence mechanisms. Seaweed extracts also contain antioxidants, which protect grass plant cells from damage caused by free radicals.

Another benefit of using seaweed in fine turf management is its ability to improve soil health. Seaweed extracts can help improve soil structure by increasing soil porosity, water-holding capacity, and microbial activity. This results in better nutrient availability and uptake, leading to healthier and more resilient fine turf.
Seaweed extracts have been found to improve the quality of fine turf by increasing turf density, colour, and uniformity. Seaweed extracts contain betaines, which are natural osmoprotectants that help grass plants retain water and maintain turgor pressure, so should be a key component in the management and recovery of LDP affected turf. It’s continued use results in a green that becomes increasingly resistant to wear and tear.

Regular use of liquid seaweed in fine turf greenkeeping can reduce the need for synthetic fertilisers and pesticides. Seaweed extracts provide a natural alternative to synthetic fertilisers, which can be harmful to the soil and plants, often encouraging high levels of damaging mineral salts to build up in the soil. Their compatibility with other organic and conventional turf management practices, make seaweed extract a versatile tool for greenkeepers.
Many of the common Seaweed extracts used in greenkeeping are super concentrated extracts of Ascophyllum nodosum with varying percentages (30-50%) of active matter harvested from renewable resources.They contain a natural balance of macronutrients and chelated micronutrients (>60 elements), carbohydrates, amino acids, antioxidants and other beneficial organic compounds.

In conclusion, the benefits of using seaweed in fine turf management are numerous and significant. Seaweed extracts can improve turf quality, reduce stress, enhance soil health, and reduce the need for synthetic fertilisers and pesticides. With its natural abundance of nutrients, growth regulators, and osmoprotectants, seaweed is an excellent tool for greenkeepers looking to improve the health and quality of their greens.

    Hi John. Would it be beneficial to mix seaweed in with compost tea and shoot. I use a mix of compost tea and shoot at the moment. Ray

    Hi
    We don’t have a sprayer, can the liquid seaweed be applied using an irrigation system, ie tipped in the water tank and applied via the pop up sprays?

      Hi Paul

      It’s not something I would recommend, but have a word with your irrigation engineer to see what they say. A sprayer would be a lot cheaper than a new irrigation pump.

      Regards

      John
