What is the relationship between Potash fertilizer and crops? What are the symptoms of potassium deficiency in crops? What effect will too much potash fertilizer have on crops?
Benefit of Potash fertilizer
Potash fertilizer is one of the three elements of fertilizer, and it is a nutrient element that crops require more. Potassium is not a component of crops, potash:
- Can promote cell growth and division
- Promote the synthesis of protein and carbohydrates
- It is closely related to the assimilation of nitrogen, the life activity of protoplasm and photosynthesis.
- When potassium is sufficient, the stems and leaves of the plant grow robustly, and the ability to resist diseases and insects, lodging and drought is enhanced.
When crops lack potassium
- The photosynthetic intensity decreases, and the tips and edges of old leaves begin to turn yellow
- When it develops to the middle and base of the leaf, the edge of the leaf is browned, and finally withered and small spot-like dead tissues appear.
- When cereal crops are lacking in potassium, it often leads to excessive nitrogen fertilizer, which leads to greediness in the later stage.
- The lack of potassium in crops can also easily reduce the resistance to pests and other natural disasters.
Therefore, it is necessary to pay attention to the application of potash in production, especially for the planting of potato crops that mainly store carbohydrates.
The increasing effect of potash fertilizer on crops has been fully realized. Therefore, the amount of chemical potash is increasing and the supply exceeds demand. Therefore, we should try to expand the source of potash, such as using fire soil ash, plant ash, etc., to solve the current potash Insufficient fertilizer has increased crop yield and quality.
