What are the 3 numbers for starter fertilizer?
The three numbers on a fertilizer label indicate the percentages of nitrogen, phosphorus, and potassium (in that order) in the formulation.
What is the composition of starter fertilizer?
Starter fertilizers come in compositions of primary nutrients nitrogen, phosphorus, and potassium (or potash), making up a product’s NPK. The numbers in the NPK statement represent percentages of nutrients. For example, a fertilizer with an NPK ratio of 10-18-10 has 10% nitrogen, 18% phosphorus, and 10% potassium.
What is different about starter fertilizer?
Depending on the brand, starter fertilizer usually contains 20% or more potassium than regular fertilizers. The extra potassium helps create a rich soil environment that will sustain the seedlings for about a month. Most starter fertilizers will contain quick-release nitrogen as well.

What kind of fertilizer should I use as a starter?
Any high-quality, complete fertilizer that contains at least nitrogen and phosphorus will work as a starter fertilizer. Generally, it should contain a high phosphate (P2O5) ratio (e. g., 1-2-1, 1-3-1, 1-4-2, or 1-5-0) and the phosphate in starter fertilizers should be highly water soluble.
What’s the ratio of phosphorous to nitrogen in starter fertilizer?
Starter fertilizers usually contain 20 percent or more of phosphorous, according to David M. Kopec of the University of Arizona Extension. Regular fertilizers have a nitrogen-potassium-phosphorous ratio of 1-2-1. The numbers refer to the percentage of each substance that the fertilizer contains.
How to calculate a fertilizer ratio for a garden?
To determine a fertilizer ratio for a recommendation of 1.5 lb of nitrogen, 0.5 lb of phosphate, and 0.5 lb of potash, divide the weight of each of the three nutrients (1.5 lb, 0.5 lb, 0.5 lb) by the nutrient with the lowest weight (0.5 lb).
Do you have to use the same ratio of N and P in fertilizer?
It doesn’t matter since they have the same ratio. If you need to add equal amounts of N, P and K, either one works just as well. However, you will have to use twice as much of the 5-5-5 to provide the same level of nutrients as the 10-10-10.
