Let’s not talk about lawn fertilizer. Let’s talk
about air. Air has oxygen and carbon dioxide and a bunch of other elements in it
but mostly air is composed of nitrogen. This is good news for your lawn since
the other day I read this, “Few soils have enough natural nitrogen to maintain
desired turf grass quality and recuperative ability throughout the growing
season.” However, the good news is that grass is one of the most efficient
nitrogen processors on the planet!
Now, if you want to fertilize your lawn, you can find plenty of information on
how to do it from every company that sells chemical lawn fertilizers on the
Internet. However, fertilizer is really just a four-letter word— food. Lawn
fertilizer, like any other type of fertilizer is plant food. Unfortunately, for
your lawn that isn’t a dirty word, because lawn fertilizer typically does
nothing for the soil. At best, it’s only a temporary fix for your turf.
Fertilizers have three major components:
•(N) Nitrogen: promotes blade growth, forms proteins and chlorophyll (the green
•(P) Phosphorus: helps root, flower, and fruit development – the last two are
probably elements you don’t want to see in your lawn!
•(K) Potassium: Helps stems and roots grow and helps your grass turn protein
into nutrients (photosynthesis)
In addition, depending upon brand, fertilizers may also contain calcium, sulfur,
magnesium, boron, manganese, iron, zinc, copper, and molybdenum. At first
glance, this looks like a good thing— sort of like a multi-vitamin for your
lawn. However, your grass, like any other plant gets its true nourishment from
the soil under it. Although excess chemical fertilizers leech into the ground,
many of the chemicals they contain do more harm than good to the complex
eco-system that provides a continuing source of nutrition for your lawn and
ultimately your turf pays the price.
The truth is that established lawns generally don’t need fertilization. If you
feel that you must fertilize your lawn, an established organic fertilizer will
enrich your soil as well as feed your grass. Don’t spoon-feed your turf.
Instead, provide your turf with a balanced diet from nutrient rich soil.
