Determining Nitrogen Fertilizer Cost Using Turfgrass Response in
Turf quality ratings were recorded weekly and used to determine response longevity and area under the turfgrass response curve .Urea resulted in response longevity greater than or equal to other N sources during each season except when applied at 98 kg·ha1 of N during the fall fertilizer cycle in Jay.Natural organics were 6-fold more expensive than urea in Jay and Ft. Lauderdale using turfgrass response longevity and AUTRC.However, if turfgrass response to SRN increases proportional to the cost, then the additional cost of SRN sources may be justified.Shaddox et al. used centipedegrass to assess the influence of four rates of urea on turf quality and reported that N applied at 18 kg·ha1 per year as urea resulted in acceptable turf quality during each fertilizer cycle over 2 years.Young et al.

How Should Starter Fertilizer Be Applied
Once youve received your soil test, selected an appropriate starter fertilizer for your soil and know the needed amounts, applying it over the lawn area is relatively basic. Just pour the required amount into a standard fertilizer spreader and evenly apply the starter fertilizer over the planting site. Once applied, work the product 4 to 6 inches into the soil, if you are planting grass seed or sod after the application. If you are applying the product after you apply grass seed, spread the product over the soil and water into the soil.
When it comes to using a starter fertilizer for new sod or grass seed, thereís a definite benefit to its use to promote the healthiest growth and establishment of your lawn in the quickest amount of time. Of course, donít go overboard with its use and think more is better. As with many things in life, too much of a good thing can be bad and too much starter fertilizer for your developing lawn can affect it negatively through burning. A soil test takes the mystery out of what your soil lacks and lets you know what strength of starter fertilizer your grass requires and how much. Used properly, it wont be long before your bare feet are enjoying the feel of your healthy lawn.

From Tons To Teaspoons
When working with small areas, flower pots, or garden boxes, we often switch from using pounds and ounces to units of volume, including pints, cups, tablespoons, and teaspoons. Though it is easy to over-apply fertilizers in this manner, the following tables should help when trying to use fertilizer recommendations based on soil testing. The fertilizer can be mixed with the soil to be put in the pot, or the fertilizer can be dissolved in water and then poured into the pot containing the soil. It is important, however, not to put all the nitrogen or potash material into the pot at one time, especially in liquid form. This can lead to excess salinity in the pot or loss of nitrogen and potash by leaching. Slow-release fertilizers should be added in the granular form. Many potting soils are sold with nutrients already mixed into the media, and additional fertilization is often not needed.
Table 2. Fertilizer Densities Used to Make Volume Calculations for Fertilizer Rates
Conversions are approximate. Fertilizers vary in density. Weigh one pint of your fertilizer to determine which density is closest to your product.
Determined from product specification sheets or Material Safety Data Sheets. Blends depend on what products are used to make grades .
To do your own volume calculation: Pints per unit area = ÷ product density. Convert to cups by multiplying by 2.

What Do The Numbers On The Bag Mean
All fertilizers have a chemical listing of N-P-K. Which means that a fertilizer listing of 28-7-14, for example, is 28% Nitrogen, 7% Phosphorous, and 14% Potassium. Some fertilizers contain trace elements, slow release nitrogen, and organic sources of nutrients.
P = Phosphorous . Phosphorous is the second number in the analysis. This nutrient is for root development and is especially important for young turf. The rapid growth associated with germination requires phosphorous, therefore it is essential in starter fertilizers. Less is required in established turf.
K = Potassium . Potassium, is associated with the plants ability to withstand stress. When supplied to the plant along with adequate amounts of Nitrogen, potassium thickens the cell wall. This makes the plant better able to withstand drought, insects, disease and cold.

Characteristics Of Nitrogen Fertilizers For Home LawnsNitrogen Type
|1. More uniform grass growth
2. Not likely to burn grass
3. Losses through soil or air less likely
| 1. May not work on cold soil
2. Most are expensive
3. May not see quick color change in grass
In addition, a variety of special lawn fertilizers may be found. Winterizer fertilizers are typically high in potassium, and although advertised for fall application can be applied in spring as well. Potassium is used all year by grasses, and is involved in heat and cold tolerance, disease resistance, and other stress tolerances. Weed and feed products contain a broadleaf weed killer for weeds such as dandelions others contain a preemergence herbicide to control crabgrass . Lawn starter products, typically high in phosphorus, are intended for newly seeded lawns and freshly laid sod.
There are a variety of organic sources of nitrogen, phosphorus and potassium available to the homeowner. As mentioned earlier most organic fertilizers are derived from plant or animal sources. Plant sources would include alafalfa and cottonseed meal and seaweed. Examples of animal sources would include bone meal and the manures from chickens, cows and horses. Yet another source comes directly from mother nature in the form of rock phosphate for a source of phosphorus and green sand for a source of potassium. Find and use products that are locally available whenever possible to keep the input costs down.

I Don’t Want To Burn My Grass With High Percent Nitrogren Fertilizer So Can I Just Use A 10
The high percentage of nitrogen by itself is not a problem, assuming the amount put down on the lawn is adjusted accordingly. The higher the percent nitrogen, the less product is needed on the lawn to supply the one pound per 1,000 square feet rate suggested. In addition, if the material is controlled-release, the risk of burning the lawn is low even though the percentage nitrogen in the product may be high.
Fast release nitrogen fertilizers, which may contain high levels of salt, can burn lawns
Balanced fertilizers, such as a 10-10-10, have a N:P:K ratio of 1:1:1. The reason these are not suggested for repeated use on lawns is the amount of phosphorus applied, when supplying the one pound of nitrogen per 1,000 square feet, becomes quite high. Excess phosphorus may lead to potential runoff problems and more weeds in the lawn. Also, many of the all-purpose balanced fertilizers have only fast-release nitrogen as the nitrogen component, so the risk of burn may be higher.

16-4-8 is considered a high nitrogen fertilizer which means it works well for most non-blooming green or leafy plants including vegetables, house plants, shrubs and even trees. It promotes green growth, as opposed to promoting flowers or fruits. In our 4 Step Garden Fertilizing Program we recommend 16-4-8 be used foliarly or through drip irrigation during the Growth Stage of your plants, up to the time they begin blossoming. For trees, use during the initial growth flush stage.
Tips For Fertilizing Grass
To keep your turf looking perfect, follow these useful tips when applying fertilizer:
- Never apply fertilizer by hand. Use a hand-held spreader for small patches, a drop spreader for small lawns, and a rotary spreader for medium to large lawns.
- Calibrate the spreader prior to using it!
- Clean up excess fertilizer from sidewalks, paths, and driveways after application. Blow or sweep it into the adjacent grass.
- To prevent fertilizer runoff, do not apply it before or after heavy rain.
- Fertilize your lawn at the correct time of year. If you have warm-season grass, apply fertilizer during summer when the lawn is actively growing. For cool-season grass, fertilize in the fall.
- Use a combination of organic fertilizer or lawn dressing, which contain slow-releasing forms of nitrogen, and chemical fertilizer, which contain quick-releasing nitrogen.

The lawn will look thicker next spring and compete well against weed seeds attempting to sprout and grow.
Another fertilizer and herbicide product is the fertilizer and crabgrass control products sold in spring. These contain fertilizer and a preemergence herbicide for crabgrass control. Once again, read and follow all label directions.
When To Apply Pasture Fertilizer
The better utilization of nutrients and fewer losses in form of leaching and volatilization for maximum output is completely dependent on the time of fertilizer application.
For pasture fields having cool-season grasses, the split application of fertilizers in late and early spring is a premium option to maximize the yields.
Make sure to never add N fertilizer during the mid-summer for cool-season grasses as it will be mostly consumed by weeds and grasses.
It does not mean from the above sentence that the summer application of N is never good for pastures. However, the N application is done for many grass pastures during the late summer for more growth.
