NPK compound fertilizer has played an important role in crop planting, but do you know the function of NPK numbers in fertilizer? As a fertilizer supplier, I'd like to introduce it to you.
Nitrogen (N): Nitrogen is needed for leaf growth and it is a nutrient that gives leaves their green color and makes leaves producing oxygen. Plants that are almost all leaves need a lot of nitrogen, so look for a fertilizer with a high first number The higher the number, the more nitrogen the fertilizer provides. This is why most lawn fertilizers are high in nitrogen. Nitrogen deficiency can be identified by yellowing of the leaves and slowing or stopping of growth. Excess nitrogen is recognized by extremely fast growth, resulting in long, weak branches and dark green leaves.
Phosphorus (P): It can promote root development, increase flowering and fruit production. Phosphorus is used more heavily during blooming and seed set. It is released in soil through decomposing organic matter. Phosphorus deficiency is identified by dark green leaves and purple stems.
Potassium (K): Potassium is also known as potash, helps the plant fight off diseases and keeps it vigorous, enabling it to withstand extreme temperatures and ward off disease. It is important for general health of plants. It also stimulates root growth and The development of the trunk. When plants are lacking in potassium, they may have stunted leaves and fruits and are particularly sensitive to drought. Because most soils already contain potassium, the third number in the fertilizer ratio is often the smallest.

The three numbers listed on the fertilizer container refer to the percentage (by weight) of the three main nutrients required for the healthy growth of the plant. They are always arranged in the same order: nitrogen-phosphorus-potassium (NPK).
If the soil test shows that the content of all three nutrients is approximately equal, choose a general-purpose fertilizer with an NPK ratio of 1:1:1. These fertilizers contain balanced nutrients and are suitable for flowers, vegetables, shrubs, trees and lawns.
If you know your soil is lacking in a particular nutrient, look for the number corresponding to this nutrient to be considerably higher than the other two.
Before planting, you may wish to work some fertilizer deep in your soil in order to promote strong root growth.
Additionally, early on in a plant's life, it needs a lot of nitrogen in order to grow large – so look for the first number corresponding to nitrogen to be higher .
Later, when it’s time for your plants to flower, you can revert back to the ratio at the beginning to help this phase of growth.
Organic fertilizers come from sources such as manure, blood meal, cottonseed meal, feather meal, crab meal, etc. Organic fertilizers work in concert with soil microbes that break fertilizers down for plant uptake. Organic fertilizers are beneficial in encouraging healthy soil biology rich in microbial activity.
Synthetic fertilizers are lab-made and derived from compounds like ammonium nitrate, ammonium phosphate, super phosphate, and potassium sulfate.
Synthetic fertilizers are great for promoting growth, but have little effect on improving the long-term health, texture, or long-term fertility of the soil
They expedite plant growth and can contribute to bloom rate in flowering plants. However, they are high in salts and can be detrimental to populations of beneficial microorganisms and also leach into water sources. Applying too much synthetic fertilizer can “burn” foliage and damage your plants.
