What is NPK and what does it do for plants?
The NPK value indicates how much nitrogen, phosphorus and potassium there is in your substrate or fertiliser. These three essential macronutrients are needed by all plants. Knowing the NPK value of your soil and fertiliser helps you give the right amount of nutrients to your plants.
Are NPK fertilizers harmless?
When fertilizer plants produce NPK compound fertilizer, they will mix the raw materials according to the proportion calculated scientifically, so NPK compound fertilizer will not produce any auxiliary components harmful to soil and plants during fertilization.
What does NPK stand for on a fertilizer label?

How do you interpret NPK ratio?
Prominently featured, the N-P-K-ratio is the percentage the product contains by volume of nitrogen (chemical symbol N), phosphorus (P), and potassium (K). A 16-16-16 fertilizer, for example, contains 16% nitrogen, 16% phosphorus, and 16% potassium.
Why is NPK important to plants?
The P in NPK is phosphorus Phosphorus stimulates root growth, helps plants set buds and flowers, and produce seeds. It also helps plants use other nutrients more efficiently, and helps turn energy from the sun into usable energy for your plants.
How is NPK calculated?
To calculate the pounds of nitrogen in a bag of fertilizer, multiply the weight of the bag by the percent nitrogen (this is the first number in the N-P-K designation on the front of the bag). This will tell you the pounds of nitrogen in the bag.

What does NPK stand for in fertilizer?
NPK stands for “nitrogen, phosphorus, and potassium” — the three nutrients that make up NPK fertilizers, and it’s one of the first things you’ll notice on fertilizer packets. While the fertilizer’s description may not specifically state “NPK,” you will find a string of three numbers separated by dashes. These figures represent the nitrogen, phosphorus, and potassium content of that fertilizer, respectively.
What to know before choosing NPK fertilizer?
Before choosing an NPK fertilizer, be sure that you know what kind of flora you have and what are its feeding requirements. Once you have figured things out, simply check for the appropriate NPK plant fertilizer that meets your needs — the numbers will be plainly marked on the package. Since the application of different types of fertilizers differs, always read the package before getting started.

What does soil testing tell you?
So if your soil is low in potassium, for example, your soil testing results will indicate that you need to add a fertilizer which is high in potassium.
What fertilizer do you use for lawns?
One of the main crops home owners grow is lawn grass and we all know that grass requires nitrogen to grow well. Lawn fertilizer is probably the most common fertilizer home owners use. For these reasons nitrogen is the most important nutrient for your plants, and the nutrient for which you need a soil test.
Why do we do soil tests?
Soil Testing – Why do it? The most common reason for soil testing is to measure the availability of plant nutrients in the soil. Soil tests can also measure things like pH, pollutants both organic and metallic, and humus levels, but the main reason for most soil tests for gardeners is to provide information about the level of nutrients .
What do you do when you take care of your soil?
If you are taking care of your soil you will be adding organic material to it. You will be mulching with organic material, and adding compost to the soil. Dead plant parts will be returned to the soil either directly or as compost, to feed future plants. You will be building up the humus level in your soil.
Does nitrogen change when you take a soil sample?
By the time you collect the soil sample, take it to the lab, and they analyze it, the level of nitrogen in the soil has changed so much that any reported value is meaningless. Remember, nitrogen is always being converted to other forms, especially a gas, and these changes take place quite quickly.
Can you use Epsom salts without soil test?
The same advice goes for home concoctions, and common products like bone meal and Epsom salts. Don’t use them without a soil test. Lawn fertilizer is a bit of an exception. Grass does need higher levels of nitrogen to grow well, and unless it is growing well, it tends to be weedy.
What is the NPK ratio?
The NPK ratio is listed on packaging to show a product’s contents by volume of nitrogen (chemical symbol N), phosphorus (P), and potassium (K). Products are designed to have higher or lower volumes, depending upon their specific use. Example: For plants with lots of foliage, they would want a higher Nitrogen volume. Flowering bulbs do well with a higher dose of Phosphorus, and fruit producing plants need more Potassium. Listing the NPK ratio on our bags helps to better accommodate your growing needs.
What does K mean in plants?
K = Potassium: For plant’s overall health and vigor. Adequate levels of Potassium ensure the overall health and longevity of plants. Plants will show they are Potassium deficient with browning/darkened edges (almost look burnt) on their leaves and will often produce very few blooms/fruit. There is no level at which K becomes toxic to plants, but excessive K can block the absorption of the other two nutrients. Similar to Phosphorous, Potassium does not move readily through the soil. Again, to do the most good, it should be applied near the plant roots.
