As well as using low-salt fertilisers to feed grass, LawnWorks uses microbial foods to sustain and improve beneficial soil life.
Soil is the heart of the lawn and is packed with diverse microorganisms that help to keep both the soil and the grass healthy. Looking after the soil is just as important as applying fertiliser. This means choosing a lawn care programme that helps both the soil life and the grass to thrive.
Soil Acidity & Liming
Grass grows well in soil that is slightly acid. Very acidic soil can cause a decrease in grass growth and plant health due to a lack of nutrient availability.
Soil microorganism activity decreases as acidity increases. This affects the lawns ability to process dead plant matter and contributes to a build–up of thatch.
A simple test will determine the acidity of your soil.
The addition of lime to soil to correct soil acidity has been used for many years in agriculture. Liming also encourages aggregation (clumping together) of soil particles which increases pore space and drainage in heavy soils.
Overly alkaline soils are less common but can be addressed by applying sulphur to the lawn.
