Fertilizer Numbers – Question: Recently You write that people One can mix two fertilizers, and “every active ingredient in one of the fertilizer combinations is also an inactive ingredient in the other.” This means that if you mix two bottles of nitrogen together, one bottle won’t. Work or not?
And you still say: “In your case The same amount of 32-10-20 added to 15-30-15 becomes the final fertilizer at 23.5-20-17.5” I have seen other examples. of the mix And for the most part, the results/ratio will be less than what you started with. So I wonder if it makes sense to mix fertilizers?
Fertilizer Numbers
Answer: To answer your first question. All active ingredients are active when mixing fertilizers. But the percentage did not increase as many people thought. Some people want to mix the two fertilizers together for a top-notch fertilizer. But it didn’t work like that.

To answer your second question Fertilizer ratios should be averaged together according to the amount of use of each fertilizer. If each type of fertilizer is used the same The final ratio will be split in half. If each type of fertilizer is used in different quantities. It is much more difficult to determine the final ratio.
In fertilizers there are active substances that help in growing plants. Each nutrient is packaged by weight percentage. The three macronutrients are usually listed in the same order of N (nitrogen), P (phosphorus), and K (potassium). A 100 pound fertilizer is labeled 10-15-20. There will be 10 pounds of nitrogen, 15 pounds of phosphorus, and 20 pounds of potassium. 10 + 15 + 20 is 45 pounds of the active ingredient. That leaves 55 pounds of inactive ingredients.
Inactive ingredients added to fertilizers are products that prevent the fertilizer from drying out or making it easier to use. Some inactive ingredients are coatings that allow the fertilizer to be released gradually. Some inactive ingredients are weeds or other chemicals. Useful but not manure, sand, sawdust, clean or sterile soil, peat moss, sphagnum moss, corncobs and other products. It is a common inactive ingredient. Inactive ingredients can affect soil structure or its ability to retain moisture.
If we have 2 packets of fertilizer left and want to combine them. What will be the final composition of fertilizer? For example, start with two bags that are both 10 pounds, one is 10-15-20 and the other is 20-20-20. The first bag contains 1 pound of nitrogen, 1.5 pounds of phosphorus, and 2 pounds of potassium. The second bag contains nitrogen, phosphorus and 2 pounds of potassium each, so if you add the active ingredient You get 3 pounds of nitrogen, 3.5 pounds of phosphorus, and 4 pounds of potassium.
The Basics Of Fertilizer
There are 3 pounds of nitrogen for a total of 20 pounds. So 3 divided by 20 is 15%. 20 pounds contain 3.5 pounds of phosphorus, so 3.5 divided by 20 equals 17.5%. Potassium has 4 pounds in 20 pounds, so 4 divided by 20 is 20%. The new fertilizer is 15-17.5-20 is not the 30-35-40 that some people expect.
Some people want to mix fertilizers to get a better fertilizer. They thought that if they could combine three packs of 20-20-20, they would get 60-60-60 extra fertilizer. They wanted to increase the percentage of all active ingredients. But forget to add all the inactive ingredients.
Sometimes it makes sense to mix the fertilizer when you have several bags of partial top. But only if the inactive ingredients allow the fertilizer to be mixed and used properly. Calculating the percentage of active ingredients becomes a much bigger math problem when you don’t mix the same amount of fertilizer. For example, the final percentage of active ingredient when you add the remaining 7 pounds of 20-10-10 to fertilizer 10. -15-10 25 lb bag Email me if you want to know the answer.

And you might be wondering what those numbers mean. The number represents the weight percentage of N-P-K, or nitrogen, phosphorus and potassium (potassium), which are essential nutrients for plant growth. Instead of seeing it as the “food” of the plant, see it as the ingredient the plant uses, along with sunlight, to produce the food (sugar) the plant needs to survive. Let’s talk about those ingredients in a little more detail.

Carbon, oxygen and hydrogen can be obtained by plants from air and water (CO2 and H2O), but nitrogen in the air is tightly bound to N2 molecules and plants cannot access it. Phosphorus (P) and potassium (K) are the minerals that are commonly found. in the soil These six elements are considered to be the primary nutrients plants need for growth. Calcium (Ca), magnesium (Mg) and sulfur (S) are the secondary macronutrients and may be deficient in some soil nutrients. Secondary nutrients include iron. (Fe), zinc (Zn), molybdenum (Mb), manganese (Mn), boron (well), copper (Cu), cobalt (Co), and chlorine (Cl). Most of these are found in soils in suitable growing sites. But it can be added if soil testing indicates a defect.
What does each of these NPK nutrients do to plants? Nitrogen promotes the growth of shoots and leaves. and necessary for plants It is temporary in the ground and must be added at least annually as the plants grow. Phosphorus is important for root and fruit growth. but it remains in the soil. So when added it must be good. This is a nutrient that promotes the flowering of algae in the Chesapeake Bay. So you rarely see this nutrient in products like lawn fertilizers. Potassium promotes stem tolerance and cold hardiness and is temporary in the soil. So we have to keep it at all times. A N/K ratio of about 1 should be suitable for most medium-sized plants.
To understand how you can improve your soil and provide the necessary ingredients for your plants, you need to try. You can guess what is in your soil by observing the growth of your plants. But the test will tell you for sure. Your county expansion representative can help you learn more. The test results will tell you what is currently in your soil. and give advice on improvements for good plant growth Recommendations are listed in pounds per 100 or 1000 square feet of nutrients. The test will tell you the pH (a measure of acidity), but we’ll cover this in a separate blog.
The recommended pound of nutrients is where the numbers on the bag come from. In our original example, 10-10-10 tells you that there is 10% N-P-K in the bag by weight. The 40-pound bag contains 4 pounds of nitrogen, phosphorus, and potassium, or 0.4 pounds of fertilizer per pound. The remainder of the bag is an inert filler. This is important because too much nutrients too close to the roots of the plant can burn the roots. Some organic fertilizers are less potent, such as Espoma’s Plant-Tone 5-3-3 Organic Fertilizer, so they can be added to the garden in large quantities.
What Do The Numbers On Fertilizer Bags Mean?
Water is important for fertilizing and is related to plants. The nutrients in the fertilizer bag are in the form of nitrates, nitrites, phosphates and potassium. which dissociate into charged ions in water These ions are then absorbed by the roots, 98% of the plant’s nutrient needs are absorbed in the water absorbed by the roots. Roots exposed to dry particles of fertilizer can be damaged. Applying chemical fertilizers one to two weeks before planting seeds or plants will allow the fertilizer to mix into the soil and fall into the solution. I’ve had good luck with Plant-Tone when planting because it’s not too strong. But after planting, it still gives good water.
