What should be ideal NPK ratio in fertilizers?What should be ideal NPK ratio in fertilizers?

The various products labeled “general-purpose fertilizers” contain either equal amounts of each major nutrient (N-P-K ratio 12-12-12, for example) or a slightly higher percentage of nitrogen than of phosphorus and potassium (such as a 12-8-6 product).Click to see full answer. Also know, what is the best NPK ratio for vegetables?Studies have found that the ideal ratio of those nutrients for flowering plants is 3-1-2. (That’s 3% Nitrogen, 1% phosphorus & 2% potassium.) So look for that ratio on the label of packaged fertilizers; anything close to a 3-1-2, a 6-2-4 or a 9-3-6 should be ideal.Additionally, what is the best fertilizer for root growth? N-P-K Fertilizer For example, a 3-20-20 fertilizer that contains 3 percent nitrogen, 20 percent phosphorus and 20 percent potassium encourages roots to grow strong and healthy. Keep the nitrogen content low, as it promotes leggy green growth at the expense of rooting, flowering and fruiting. Accordingly, what is the best ratio for lawn fertilizer? Recommended ratios of N-P-K for lawn fertilizers include 3:1:2 or 4:1:2. Another important factor in choosing nitrogen fertilizers is what kind of nitrogen is actually in the product. Nitrogen fertilizer may consist of fast-release or controlled-release nitrogen.What is the NPK ratio?Definition as written by paulgrow: This term refers to the ratio of nitrogen (N), phosphorus (P), and potassium (K) in fertilizers. It is always expressed as N-P-K. For example, a fertilizer labeled as 24-6-6 has 24% nitrogen, 6% phosphorus, and 6% potassium.
