In calcareous soils with high pH, orange trees often struggle to absorb potassium due to the blockages caused by excess carbonates and calcium. Potazufre^® acts by unblocking nutrients and gently acidifying the root environment, improving potassium uptake and fertilization efficiency.

Orange trees require a balanced nutrition to produce high-quality fruits with optimal color, size, and flavor. However, in many citrus-growing areas, calcareous soils with high pH make it difficult for plants to assimilate potassium and other essential nutrients.

Excess carbonates and calcium saturation block available elements, reduce root activity, and limit fertilization efficiency. Therefore, it is essential to use potassium sources that are soluble, stable, and capable of improving nutrient availability under these conditions.

Potazufre^®:

Potazufre^® is an effective alternative to overcome soil blockages that hinder potassium absorption. It is specifically designed for fertigation use and combines fully soluble potassium with sulfur in a reduced form.

Potazufre^® is able to unlock nutrients and gently acidify the root environment. In calcareous soils, this action enhances potassium uptake, maintains soil ionic balance, and stimulates microbial activity, resulting in more uniform fruits with better color and higher sugar content.

It is recommended to apply Potazufre^® during the fruit sizing and ripening stages, when potassium demand is at its highest. The recommended rates range from 20 to 40 L/ha per week, depending on crop load and irrigation water conductivity.

These recommendations are indicative and should be adjusted according to specialized technical criteria. For optimal management, it is advisable to consult an agronomic advisor or contact our technical department.

Effective potassium fertilization in orange trees grown in calcareous soils with Potazufre^®.

Potazufre^® provides a practical and efficient solution for potassium nutrition in orange trees grown in calcareous soils. Its unblocking effect and high potassium availability help maintain plant balance, improve fruit quality, and optimize irrigation efficiency, ensuring effective fertilization even in difficult soils.

To maximize the efficiency of the fertilization program, it is essential to perform soil and leaf tissue analyses, adjusting doses according to crop requirements. Proper irrigation management ensures optimal nutrient uptake. In addition, foliar applications should be carried out during the coolest hours of the day to enhance effectiveness and reduce evaporation losses.
