Balanced Fertilizers Why Fertilize
Lawns? Properly timed
fertilizer applications help maintain healthy lawns and landscapes.
Many landscapes are growing in poor quality soil because of
construction activities during installation of streets and driveways
as well as during excavation for the house's foundation walls. Under
these growing conditions, fertilizing lawns and trees and shrubs is
essential to meet their basic nutrient requirements. Fertilization
rates and application frequency directly influence color, growth
rate, and density of a lawn. Lawns fertilized infrequently are thin
and are prone to weed invasion. Insect or disease damage will be
slow to recover and fill-in. Our experience has taught us that
fertilizing lawns during the growing season helps them maintain
uniform color and develop a dense carpet-like appearance. This also
enables them to withstand stress and invasion by weeds. Frequent
fertilization rather than every other month helps maintain a more
uniform color without increasing the annual fertilization
rate. Would Organic Fertilizer
Be Better For My Lawn? Plants absorb
nutrients in the same way, whether the source be organic or a
conventional fertilizer. Turfgrass roots will only absorb dissolved
nutrients found in the soil water. Organic fertilizers do not offer
any advantages to the care of your lawn. The choice is strictly
personal preference. Complete vs. Balanced
Fertilizers Fertilizer is
any material supplying one or more essential plant nutrients. Most
common turfgrass fertilizers include nitrogen, phosphorous and
potassium, but they may also include other essential mineral
elements for turfgrass growth. -
Complete fertilizers contain
nitrogen, phosphorous and potassium, but they may also include
other essential minerals elements for turfgrass
growth. -
Complete fertilizers contain
nitrogen, phosphorous, and potassium in the same product. If a
fertilizer contains less than all three elements it is referred to
as an incomplete fertilizer. If urea, a 46-0-0 incomplete
fertilizer, is used for every application through the season,
lower turf quality may result if other essential elements are not
being supplied by the soil. -
Balanced fertilizers provide
nutrients in a predetermined ratio that best meets he plant's
requirements for those elements. Turfgrasses require nitrogen,
phosphorous, and potassium in the approximate ratio of 3-1-2,
4-1-2, or 8-1-3. -
Remember that the right balanced
fertilizer ratio will differ with grass type, and is also
influenced by soil levels of certain
elements.
