Almost all fertilisers have 3 numbers on their label, known as the NPK, which is why they are often called NPK fertilisers. This is referring to the ratio of the 3 active ingredients in the mix. N - The chemical symbol for nitrogen. Plants use nitrogen to create lush foliage and dense green growth. P - The chemical symbol for phosphate
To determine a fertilizer ratio for a soil test 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) listed on the report by the lowest nutrient weight (0.5 lb in this case). 1.5 รท 0.5 = 3. 0.5 รท 0.5 = 1.
This tells us that a 5-1-2 NPK ratio is good but it doesn't quite supply enough P and K over the long term to support healthy top growth without eventually depleting the soil's balance of P and K. By increasing the ratio to 8-2-5 this adds enough P and K relative to N to support healthy top growth while not slowly depleting the soil's
The best fertilizer for fig trees typically contains a good balance of macronutrients and micronutrients, with Nitrogen (N), Phosphorus (P), and Potassium (K). The NPK ratio for fig trees is typically 10-10-10 or 20-10-20, but a soil test can help determine the specific ratio needed for your fig tree.

The NPK numbers on fertilizer show the percentage of nutrients per pound of fertilizer, not the actual amount. N, P and K refer to nitrogen, phosphorus, and potassium. For example, if the N listed on the fertilizer package is 7 (meaning 7% nitrogen), such as with E.B. Stone's Fruit Tree fertilizer , then there is 0.07 pounds of actual
The best fertilizer for bermuda grass is one with plenty of nitrogen, some potassium and little to no phosphorus. This blend of nutrients, called the NPK ratio, will help your bermuda grass look its best. Most fertilizers come in liquid, water-soluble or granular form. Both liquid and water-soluble fertilizers are easy to apply.
