Are you unhappy with the way your lawn is looking? Don’t worry, CONTACT US NOW for your FREE Lawn Review. We will take care of your lawn, turning it into a lush green and healthy lawn you will be proud of.
Most homeowners want a lush attractive lawn. For lawns to look their best, they need a little help and attention. Like all living organisms grass needs nutrients to survive and thrive. Your soil will naturally provide some of the nutrients required, but most soils will not be able to provide the correct level of all of the required nutrients.
Good Lawn Fertilisation is important for a healthy lawn.
Regular application of the correct, seasonally balanced Fertiliser is essential to maintain the health and appearance of your lawn.
Throughout the year your lawn needs different amounts of specific chemical elements as these assist various processes which naturally take place within the plant.
Lawnscience provides lawn fertilisation applications for lawns throughout the year as part of its annual treatments cycle. You can book an annual plan tailored to your needs and budget or a “one off” application.
To arrange a free assessment of your lawn fertilisation needs, please contact us and we will arrange a no obligation assessment, or read on to learn more about fertilisation and your lawn.
How will your lawn benefit from a Lawn Fertilisation?
The lawns we desire today are not as natural as we think. The grass plant naturally thrives in a “polyculture’ this is an environment in which different plant species exist side by side. In polycultures, the various species tend to help each other to survive. A good example would be clover and grass. Clover has a symbiotic bacteria within its root system enabling it to “fix” Nitrogen, which is helpful to the grass plant as it converts atmospheric nitrogen into nitrites, which can be utilised by the grasses’ roots. Clover roots are also deep, often two feet deep. These roots store carbon and move nutrients up higher in the soil profile, where the grasses’ shallow roots can access them.
Lawns we desire are “monocultures”. They are created to suppress species considered undesirable, such as weeds. Monocultures are not natural environments for grass, therefore we need to assist the grass by supplying nutrients.
What is in a Lawn Fertilisation Treatment?
Fertilisers are added to soil, so they supplement naturally occurring nutrients and elements required to promote the healthy growth of the grass plant.
There are two main types of Lawn Fertiliser:
Manufactured or Inorganic Fertilisers contain synthesised or manufactured nutrients. They are more often concentrated and provide quicker results.
Organic Fertilisers are created from animal sources or plant nutrients. A slow acting fertiliser due to the organic inputs that are broken down by organisms within the soil, before the nutrients are available to the grass plant.
Nutrients are divided into macro and micro nutrients. Both of these are important for the health of the grass plant. Macro nutrients found in plants have a concentration of above 1000 parts per million. Micro nutrients have a concentration of 100 parts per million or less.
The main three macro nutrients are, Nitrogen (N), Phosphorous (P) and Potassium (K). Lawn Fertilisers will normally have a label indicating the percentage of these three elements, i.e. 22-5-8 which equates to 22% Nitrogen, 5% Phosphorous and 8% Potassium. The rest of the ingredients are fillers and anti-caking additives.
Nitrogen is an essential element for all living organisms. It is readily available in the atmosphere, 80% of the air is Nitrogen gas. Grass roots utilise this once converted into a nitrate or ammonium.
Nitrogen is a component of many of the biochemical processes which take place within the plant. One of its main uses is the production of Chlorophyll, which gives grass its green colour. It also plays a key role in photosynthesis, the process where the grass plant converts light energy from the sun into chemical energy stored in carbohydrates. Nitrogen is also active in the production of amino acids and proteins.
Grass needs Nitrogen in the largest quantity during its growth peak in Spring. This is because during this time of the year the plant is actively growing. The process of Photosynthesis is working full steam producing the carbohydrates required to drive growth.
An application of the correct lawn fertilisation at the correct time of the year is important for your lawn’s health
A great lawn care company will only apply Nitrogen to grass in the correct quantity for the time of year. Too much and the grass leaf turns yellow. This indicates chlorosis, which is a lack of chlorophyll. Too much and the plant will produce excessive amounts of above ground tissue at the expense of root development.
Present within every living cell in the grass plant, Phosphorous plays a key role in many of the plant compounds that are essential for growth. Its main function within the plant is the storage and transfer of energy. Insufficient Phosphorus restricts the normal growth and development of grass plants. The development of the root system adversely affects the seed production.
Grass requires relevantly high levels of Potassium, second only to Nitrogen. It plays an important role in the growth and development of the plant. It helps the grass plant to develop thick cell walls making it more resistant to excessive heat and cold. High levels of Potassium help increase your grass plants resistance to fungal diseases such as Red Thread and Fusarium.
The remaining macro nutrients are Sulphur, Magnesium and Calcium.
