The first of the three most prominent numbers on any bag of fertilizer is the percent of nitrogen in that product. A 100 pound bag of 10-10-10 contains 10 pounds of nitrogen (as well as 10 percent phosphoric acid and 10 percent soluble potash)..
In respect to this, how do you calculate nitrogen in a fertilizer bag?
To find the amount of nitrogen in a bag of fertilizer, you must calculate the pounds of nitrogen per 1,000 sq. ft. To calculate the pounds of nitrogen in a bag of fertilizer, multiply the weight of the bag by the percent nitrogen (this is the first number in the N-P-K designation on the front of the bag).
Subsequently, question is, what is in a bag of fertilizer? The Three Main Nutrients That Are in the Bag A fertilizer has three numbers printed on the package that state the percentage (by weight) of the three main plant nutrients—nitrogen (N), phosphorous (P), and potassium (K). For example, you might see a bag labeled 4-7-6.
Accordingly, how much does a bag of fertilizer cover?
50 lb ÷ 3.8 lb = 13.2. Now multiply 13.2 by 1000 sq ft: 13.2 x 1000 sq ft = 13,200 sq ft. Thus, a 50-lb bag of 26-5-10 covers 13,200 sq ft at a rate of 1.0 lb nitrogen per 1000 sq ft.
What kind of fertilizer is high in nitrogen?
Organic fertilizers that are high in nitrogen include urea, which is derived from urine, feathers, dried blood and blood meal. Feathers contain 15 percent nitrogen; dried blood contains 12 percent nitrogen; and blood meal contains 12.5 percent nitrogen.
