It ’s time to demystify how to calculate fertilizer rate . After all , it ’s just unsubdivided math . You ’ve hail to the veracious office . In the mail service below , I ’ll interrupt down everything you ask to make love about how to calculate plant food rates .

A soil test will secernate you the ratio of potassium , phosphorus , and N in your soil . These are the most crucial macronutrients in your grease and are essential for healthy plants . The N - P - K ratio on your fertilizer promotion refers to the proportion of these macronutrients present in the fertilizer . So to know how much to add , you necessitate to know how much is already there .

Now it ’s time to break out the calculating machine and do some math . You ’re seem for that magic proportion on the traveling bag of fertilizer . It is get it on as the N - P - K proportion , and it constitute the percentage of each major nutrient present per bag of fertilizer .
To determine the actual amount of any picky nutrient in the bag , multiply the bag ’s weight with the ratio of that special food in denary form .
For case , let ’s say the N - atomic number 15 - K proportion is 15 - 16 - 17 for a 25 lb bag of fertiliser . The 15 in that proportion refer to the per centum of nitrogen in that fertilizer . So the bag of fertilizer in this object lesson is 15 percent nitrogen . You want to make love how many pound sterling of atomic number 7 are present in the bag . 25 x 0.15 = 3.75 . There are 3.75 pounds of N in that 25 lb bag . you could use the same rule to account the other nutrients as well .
Step Four: Determine How Much Fertilizer Is Needed

It is where the information you find in Step Two come into play . To determine how many pounds of plant food you need to hit your hope amount of one specific food , you ’re going to need your computer again .
Divide the percentage of that nutrient ( in decimal shape ) into the desire phone number of Syrian pound for that particular nutrient .
For instance , let ’s say you need 2 lbs of N for a particular software . You ’re still using the 15 - 16 - 17 plant food from the example above . So , 2 x 0.15 = 13.33 lbs of fertilizer to reach 2 pound . of nitrogen in a special region .
Further Considerations
The urge fertiliser rate for any render works usually refer to the annual prerequisite of nutrients for that particular works .

Find what works best for you and your climate .
