Without a soil test the consensus of most experts is very clear… a balanced NPK ratio of 4-1-2 is the best fertilizer for all lawns. Yes, you will hear arguments in many ways, but the experts (and our testing) has shown that this ratio is best overall ration for a regular maintenance fertilizer.
In most cases, a rate of one pound of nitrogen per 1,000 square feet is suggested for each fertilizer application to the lawn. If high percentage nitrogen fertilizers are used, then less actual fertilizer product is needed to supply that one pound compared to fertilizers with low percent nitrogen. Recommended ratios of N-P-K for lawn fertilizers include 3:1:2 or 4:1:2 → Link to Citation
Good maintenance type fertilizers should be in a 3-1-2 ratio of nitrogen (N) to phosphorus (P) to potassium (K). An example of a 3-1-2 ratio fertilizer would be a 15-5-10 or something relatively close to this. → Link to Citation
If you have not had a soil test, apply a fertilizer that is four to six parts nitrogen, one part phosphorus and two to four parts potassium. A 16-4-8 fertilizer analysis would fall within this range with a 4-1-2 ratio of these nutrients. → Link to Citation
Use a 3-1-2 or 4-1-2 ratio fertilizer if you elect not to conduct a soil test. A common example of a 3-1-2 ratio fertilizer is 15-5-10,while a good 4-1-2 ratio fertilizer is 16-4-8.These ratios generally supply what most lawns need, and they won’t dramatically increase the phosphorus levels if it’s unneeded → Link to Citation
