Potassium deficiency
- Name of the disease
Potassium deficiency
- The scientific name
Potassium deficiency
- Type of disease Family of disease
Type: non-vital
Disease family: Physiological diseases
- Symptoms of the disease
Symptoms of its deficiency: Potassium plays an important role in vital processes. It is necessary in the formation of proteins and carbohydrates and the reduction of nitrates in plants. It helps in converting carbohydrates into fats. It is an auxiliary factor of great importance in chemical processes within the plant. It activates some protein-producing enzymes and also helps in the metabolism of Protein. Potassium increases the effectiveness of enzymes involved in carbohydrate exchange and accumulation of sugars and starch, and encourages the transfer of carbohydrate materials from processing areas to storage sites.
The effect of increasing it: Excess of Potassium: Excess potassium causes poisoning to the plant, but it is a rare occurrence, and can only occur in the case of prolonged use of potassium or nitrogen fertilizers. The harms caused by excess potassium are as follows:
- High levels of potassium are not directly toxic, but the main effects appear to be a deficiency in other ions such as: calcium, magnesium, and iron.
- Potassium is alkaline; Therefore, high concentrations of more than 3% in leaves can have a harmful effect similar to alkali damage.
- Potassium can work with sodium or be a substitute for it, thus creating an imbalance in the sodium to calcium ratio.
- The causes of disease
Soil pH has a significant impact on the availability of potassium for plants. It is available in soils characterized by a pH of 6-7 or more, and symptoms of potassium deficiency appear frequently in light sandy lands. It is worth noting that most lands contain a large percentage of potassium, but in An insoluble form, and there is a definite relationship between the amount of dissolved potassium in the soil and the amount of clay in it, as clay-rich lands contain high amounts of dissolved potassium.
- Conditions suitable for the spread of the disease
It decreases relatively in pH from 5-6 and becomes severe in pH less than 5, light sandy lands.
- Photos of the disease at its beginning and after its spread, in high quality, at least 5 photos in high quality
- Losses of disease spread

- Control strategy
- Chemical fertilizer
- Organic fertilizer
- Fertilizer recommendations
Fertilizing with fertilizers rich in potassium, such as MKP (0-52-34) fertilizer, or fertilizers in which potassium is present in a high percentage, such as potassium thiosulfite.
- Anti-membership recommendations
Fermented organic fertilizer
