supply a fertilizer to your lawn will makethe grass greener and stronger , as long as you apply the right-hand amounts of the right kind at the right meter . With so many complications , it may be helpful to realise what each constituent of lawn fertilizer does so you could well understand your overall lawn care needs .

Plant Nutrients

Plants need up to 18 food to uprise right , but only three of them — N , daystar and potassium — are used in quantities that might command supplements . fertilise a lawn is simply the process of adding the deficient elements to the soil so the lawn has the best luck of success . Lawn fertilizer is sell with a numeric analysis on the package , normally something like 10 - 10 - 10 or 20 - 4 - 8 , with the three number match to the share of nitrogen , phosphorus and potassium , in that order , in the fertilizer .

Nitrogen

Of all plant nutrients , nitrogen is required in the largest quantity and is the most common nutrient to be deficient in soil . Nitrogen plays a role in almost all internal processes , from synthesize proteins to creating chlorophyll . Lawn plant food have two types of nitrogen : fast press release and slow discharge . Quick - button fertilizers will have the pasture green and grow within a few days , but will ask more frequent program program . Slow - discharge N will take a picayune longer to show effects , but will require less frequent practical app and has a much lower chance of apply too much atomic number 7 .

Phosphorus

Phosphorus is perhaps more important to a lawn ’s overall wellness than any other food , but it is required at much lower levels than nitrogen . Phosphorus is required for just about every vigor procedure inside the grass , including amino group acid production , photosynthesis , glycolysis and respiration . Phosphorus is especially important for newfangled grass , as it promotes root ontogeny and stimulates brand growth .

Potassium

While potassium is n’t used in the canonical cell social system of the grass , it is ask for many of the grass ’s underlying growth process . Potassium is a need constituent of photosynthesis and help oneself facilitate cell division . atomic number 19 also increase the turf ’s resistance to traffic and disease and even drouth tolerance . Potassium is also live for helping the weed survive through the wintertime months .

Fertilizer Misuse

Since fertilizer is design to supplement eat or deficient territory , it is important to only use the right amount , and the right kind , of plant food . Using too much nitrogen , for example , can overstimulate maturation causing the blades to get strong but the roots to be too weak to bind the works . Nitrogen can also cause damage to the grass blade if you go for fertiliser and bury to instantly irrigate the plant to knock the fertilizer off the grass and into the soil . Elevated levels of phosphorus and potassium do n’t hurt the grass as much as nitrogen , but the supernumerary levels will strip out of the dirt and into the groundwater . Some locale may even have laws against apply phosphorus and potassium fertilizer except in specific circumstances .
