the Fertilizer Label
|All fertilizer labels have three bold numbers. The first digit is
The first number represents the quantity of nitrogen (N), while the second number represents the amount of phosphate.
(P2O5) and the third number is the amount of
potash (K2O). These three numbers represent the primary
nutrients ( nitrogen (N) – phosphorus (P)
– potassium (K)).This marking is a national standard known as the fertilizer grade.
A bag of 10-10-10 fertilizer includes 10% nitrogen, 10% phosphorus, and 10% potassium.
|Fertilizer grades are created by combining two or more nutrient sources.
They are termed “mixed fertilizers” because they combine several sources to make a mixture.
Blends contain particles of more than one color. Manufacturers create
different grades for the many types of plants.There are fertilizers available that include just one of each of the basic nutrients.
nutrients. Nitrogen sources include ammonium nitrate (33.5-0-0), urea nitrogen
(46-0-0), sodium nitrate (16-0-0) and liquid nitrogen (30-0-0). Phosphorus
is available in 0-46-0 form, and potash in 0-0-60 or 0-0-50 form.
|To calculate the pounds of nitrogen in a 50-lb bag of
10-10-10 fertilizer , multiply 50 by 0.10. Do the same for calculating
the amounts of phosphate and potash. A 50-pound bag of 10-10-10 has a
15 pounds of nutrients: 5 pounds of nitrogen, 5 pounds of phosphate, and 5 pounds of potassium.
potash. The remaining weight is filler, usually sand or granular limestone.Another example:

a Fertilizer Grade
|The easiest approach to choose a fertilizer grade is to consult with your soil tested . The soil
test report will recommend a fertilizer grade for your use. The document
also includes a management note with supplementation instructions

stripes. This was probably caused by spreading fertilizers the wrong way.
Fertilizers are used to ensure that the color and development of your plants are consistent.
It must be distributed equally. The most popular types of fertilizer spreaders are
the drop spreader and the cyclone spreader. In general, cyclone spreaders
deliver the finest outcomes. Make sure when you spread the fertilizer that

and the rest in the other way. Break up any clumps so that
the fertilizer won’t get clogged in the spreader.
Are higher fertilizer numbers better?
Nitrogen (N) is required for leaf development and is responsible for the greening of plants. Plants with nearly entirely leaves need a lot of nitrogen, therefore choose a fertilizer with a high first number. The higher the number, the more nitrogen is provided by the fertilizer.
Is 28 0 3 fertilizer good?
Weed Control & Fertilizer in Greenlawn 28-0-3 destroys over 250 weeds while also feeds your lawn. The 28-0-3 formula promotes rapid root growth and deeper roots to better retain water and protect from heat and drought.
What is the best ratio for plant fertilizer?
Gardeners often use the following fertilizer ratios:
- Rooting: 1-2-1.
- Flowering and fruiting: 1-1-2, 1-2-2, 2-1-2.
- All-purpose: 1-1-1.
- Leafy growth: 2-1-1, 3-1-1.
What does a 20 20 20 fertilizer mean?
It contains equal amounts of nitrogen (20%), phosphorous (20%) and potassium (20%) to provide a balanced formula for your vegetable plants. The nitrogen promotes vegetative development, while the phosphorus and potassium assist your plants develop a strong root system.
