Surely everyone knows this kind of thing, right? As long as there are crops at home, fertilizer will be used. Did you know that fertilizer has three elements? What effect do these three elements have on crops? What would happen if these three elements of crops were omitted? Let’s take a look with the editor below.

What are the three elements of fertilizer

1. Nitrogen fertilizer: It is the main component of protein and chlorophyll in crops. When nitrogen is sufficient, the branches and leaves are lush and dense, photosynthesis is strong, the production of organic matter is much, the body is strong, the tiller is fast, the ears and grains are full, and the yield is high. When there is a lack of nitrogen, crop plants are short and weak, yellow leaf color grows slowly, and yield is low. When nitrogen is too much, it will cause crops to grow wildly, easy to be green and late, easy to lodging, and weaken resistance to drought, cold, and pests.

2. Phosphate fertilizer: Phosphorus is contained in seeds and is the main component of plant cell nucleus. Phosphorus can promote plant germination, root growth, branching, fruiting and maturity. When crops are deficient in phosphorus, the stems and leaves of plants are often purple, reddish brown or abnormal gray-green, with late flowering and small fruit.

3. Potash fertilizer: Potassium can increase the intensity of photosynthesis. Normalize metabolism, enhance cold resistance, promote stalk health, and enhance lodging resistance and disease resistance. When potassium is deficient, the plants are thin, with few branches and tillers, and the leaves become dry and fall off from the old leaves, and the yield is not high.

What does it do

Nitrogen has a significant effect on promoting plant growth and health

Potassium can enhance the ability of plants to tolerate various adverse conditions, such as drought, low temperature, salt content, pest damage, lodging, etc.

Phosphorus can promote the formation and growth of early root systems, improve the ability of plants to adapt to external environmental conditions, and help plants to withstand the severe cold in winter

What happens to missing crops

Nitrogen deficiency: The plant is light green, the old leaves at the base turn yellow, and brown when dry. The stem is short and thin, with few branches or tillers, and premature aging occurs. If the fruit tree is deficient in nitrogen, there will be phenomena such as small fruit, few fruit, and hard skin.

Phosphorus deficiency: Plants are dark green, often red or purple, dark green when dry. The stem is short and thin, the base leaves turn yellow, the flowering period is delayed, and the seeds are small and not full.

Potassium deficiency: The old leaves are first yellowed along the edge of the leaf, and the edge of the leaf becomes burning when it is severe.
