5-10-30 fertilizer, also known as starter and centipede formulation, is a traditional fertilizer mix used for generations in farming and landscape maintenance. This formulation adds a small amount of nitrogen, but is higher in phosphorus and potassium. Phosphorus and potassium are important in early spring to encourage healthy and more prolific root growth in warm-season grasses. 5-10-30 fertilizer is also the go-to formula for centipede lawns because it's low in nitrogen. Fertilize centipedegrass based on the feedback from a soil test – your centipede lawn may not need fertilizing at all and can be damaged, especially with too much nitrogen.
What does 5-10-30 fertilizer mean?
The numbers refer to the percentage of nitrogen (N), phosphorus (P), and potassium (K) in the fertilizer. The first number in the chemical formula tells you how many molecules of that material are in the compound. For example, “fifty” or “five.” This promotes leaf growth. Higher-numbered pounds per thousand square feet mean a higher concentration of phosphorus and/or potassium.
So what does this mean? This formula indicates that five percent of your plant's nutrients would come from nitrates, ten percent from phosphate rock minerals, and thirty percent from potash ore minerals. Nitrate fertilizers are formulated with ammonium ions as well as other forms such as calcium ammonite sulfate ion combinations depending on weather conditions specific to each location.
When to use 5-10-30 fertilizer?
5-10-30 fertilizer is generally used:
- As a starter fertilizer for trees and other woody plants to get them off to a good start in the spring before they leaf out
- To replace nutrients lost by leaching or as plant material is broken down, especially if you're planting on sandy soils where water drains quickly and does not allow fertilizer time to be absorbed into the soil profile

How to apply 5-10-30 fertilizer?
When applying 5-10-30 fertilizer, follow these steps:
-
Prepare the soil: Loosen the soil to a depth of at least 12 inches to allow the fertilizer to reach the root zone of the plants.
-
Calculate the appropriate amount: Divide the total area you want to fertilize by 1,000 and multiply by 5. This will give you the total pounds of fertilizer needed. For example, if you need to cover 10,000 square feet, you would need 50 pounds of fertilizer.
-
Broadcast the fertilizer: Scatter the fertilizer evenly across the area, making sure it is applied to the entire area.
-
Till the fertilizer into the soil:轻度 till the fertilizer into the soil to a depth of at least 4 inches to ensure that the nutrients are available to the roots of the plants.
-
Water in: Water the area well after broadcasting the fertilizer to ensure that the nutrients are absorbed.
