When to use high potassium 12-6-40 fertilizer?
Used during stages when the plant needs high potassium, such as after setting, fruit enlargement, fattening, and improving fruit quality before harvest. Therefore, it is more suitable for the fruiting stages, not the initial establishment or root strengthening stages, which usually require higher phosphorus.
It can be incorporated into foliar fertilization programs or fertigation depending on the appropriate method for the crop, taking into account the plant type, growth stage, soil condition, and irrigation system.
Benefits of potassium in increasing fruit size and quality
Potassium is one of the most important elements during the fruiting stage; it supports sugar transfer within the plant, helps improve fruit filling, firmness, color, and marketability quality. Therefore, high-potassium formulations like Sangeral Flex 12-6-40 are suitable for crops that need clear support during the fattening stage.
How to use Sangeral Flex 12-6-40
Use according to the package instructions or the recommendation of an agricultural specialist.
- Protected cultivation: approximately 0.5 to 1 kg per 500 m² with irrigation water.
- Fruit-bearing stage: approximately 1 to 2 kg per 500 m² with irrigation water.
- Drip irrigation: approximately 7 to 10 kg per hectare depending on crop condition.
- Foliar spray: approximately 2 to 3 kg per 1000 liters of water.
- Vegetables and fruits: approximately 5 to 6 kg per hectare depending on growth stage.
Preferably used early morning or evening to reduce heat stress and improve absorption.
Difference between Sangeral Flex 12-6-40 and high-phosphorus fertilizers
Sangeral Flex 12-6-40 focuses on potassium, making it suitable for fattening and improving fruit size and quality. High-phosphorus fertilizers like 10-52-10 or 15-30-15 are usually more appropriate for root strengthening and early flowering. Choosing the right fertilizer depends on the plant’s stage, not just the product name.
Precautions for using high-potassium fertilizer
- Do not use high doses without knowing the plant’s actual needs.
- In saline or poorly drained soils, adjust irrigation and drainage before increasing fertilization.
- Avoid random mixing with pesticides or other fertilizers before compatibility testing.
- Do not use as a complete substitute for a balanced fertilization program that includes other elements.
- Store in a dry, cool place away from moisture and direct sunlight.
