Potassium monophosphate is a modern, highly effective fertiliser widely used in horticulture and gardening. Its chemical formula is KH₂PO₄. Thanks to its potassium and phosphorus content, this product provides plants with the necessary elements to strengthen the root system, improve shoot maturation and prepare for winter.
Composition of potassium monophosphate
| Substance | Content per 100 g |
|---|---|
| Potassium oxide (K₂O) | 34 g |
| Phosphorus (P₂O₅) | 52 g |
| Other impurities | up to 1 g |
In what form is it sold?
Potassium monophosphate is produced in the form of a crystalline powder or small granules that dissolve well in water. Thanks to this property, it is quickly absorbed by plants.
The effect of potassium monophosphate as an autumn fertiliser
In autumn, plants especially need potassium and phosphorus. Potassium strengthens tissues and increases frost resistance, while phosphorus helps roots to better accumulate energy and develop. Applying potassium monophosphate under trees and shrubs in autumn ensures:
- improved winter hardiness of crops;
- strengthening immunity against diseases;
- abundant flowering and fruiting the following year;
- active development of the root system.
How to prepare a working solution
| Crop | Solution concentration | Application rate |
|---|---|---|
| Shrubs (currants, gooseberries, raspberries) | 10 g per 10 l of water | 5 l per bush |
| Fruit trees (apple, pear, plum) | 15 g per 10 l of water | 20-30 litres per tree |
| Grapes | 10-15 g per 10 litres of water | 10-15 litres per bush |
Foliar feeding
Potassium monophosphate is often used for foliar treatment. For this purpose, a weaker solution is prepared: 2-3 g per 10 litres of water. Such feeding stimulates photosynthesis, strengthens immunity and helps plants accumulate nutrients before wintering.
Autumn application of potassium monophosphate is an important agricultural technique that helps trees and shrubs better prepare for winter conditions. Proper use of this fertiliser ensures healthy plant development and a rich harvest in the following season.
