Sunlight, water, and nutrients are essential to help grass grow faster, but the specific chemical responsible for the growth rate is nitrogen. Nitrogen helps stimulate the development of chloroplasts and photosynthesis, critical for healthy grass growth.
Nitrogen comes from fertilizer, compost, manure and natural mineral deposits in soil which is released when soil bacteria break down organic materials into usable forms.
Too much nitrogen can be detrimental; plants may become stunted or yellowed while too little will cause slower growth. It’s important to understand the world around us to find a balance between these two extremes that favors optimal growth rates.
Another key element in helping promote healthy grass growth is phosphorous. This mineral helps support root development, accelerate maturing of plant cells and encourages new leaf growth. Again, a phosphorus imbalance can lead to ill-effects on your grass and it must be used in combination with nitrogen to obtain desired results.
Lastly, potassium increases stress tolerance in plants by helping build cell walls for better disease resistance which can result in faster and healthier growing grass blades throughout its life cycle . In summary, both nitrogen and phosphorous play key roles in accelerating grass growth when used judiciously and with careful management.
