Technical Information: AminoQuelant-K low pH in potatoes, key during peak tuber filling in Southeast Buenos Aires

This stage defines caliber, uniformity, dry matter and industrial suitability, variables directly linked to the efficiency in the mobilization of photoassimilates towards the tuber.

Potatoes are among the crops that extract the most potassium per ton produced. During the period from tuberization to full tuber fill, the physiological demand increases markedly. Potassium is involved in osmotic regulation, enzyme activation, carbohydrate synthesis and transport, and starch accumulation. When this nutrient is not efficiently available during this stage, the crop may exhibit the following symptoms:

• Smaller commercial caliber
• Unevenness in filling
• Decrease in dry matter
• Loss of industrial quality

In this context,  AminoQuelant-K low pH , a fertilizer developed by  Brometan SRL , offers a unique technological solution. Its formulation combines:

• 27% w/v soluble element potassium
• 6.6% w/v of free L-α-amino acids obtained by enzymatic hydrolysis
• 1.33% w/v of organic nitrogen

Potassium is organically complexed with biologically active free amino acids, which promotes rapid absorption and efficient internal translocation to storage organs. This amino acid-potassium complex facilitates movement via the phloem, optimizing the flow of photoassimilates to the tuber during periods of peak physiological demand.

A key technical aspect is its neutral pH, which prevents the alkalization of the application solution —a common problem with many potassium sources—and ensures high compatibility with common pesticides and fertilizers. This characteristic is especially strategic in southeastern Buenos Aires province, where pest and disease management programs are intensive and combined applications are frequent.

According to Agricultural Engineer Carlos Tajan, Head of Potato Cultivation for Argentina and Uruguay, “the correct provision of potassium with AminoQuelant-K low pH in filling stages allows optimization of the movement of photoassimilates towards the tuber, improving size, uniformity and commercial quality, especially under the productive conditions of southeastern Buenos Aires, where the yield potential is high and the industrial demand is high.”

For his part, Agricultural Engineer Ignacio Álvarez, Brometan’s Development Technician in the region, noted that "in plots where we incorporated AminoQuelant’s efficient potassium into the nutritional scheme, we observed greater efficiency in the internal mobilization of potassium and better uniformity in filling."

From southeastern Argentina, the technical team highlights that the product can be applied both via foliar spray and fertigation, with indicative doses of 1 to 2 L/ha according to the crop’s requirements, easily integrating into nutritional and health programs.

In a growing season where tuber filling determines the final outcome, strategic potassium management is not just a complementary practice: it is an agronomic decision that makes a difference in yield, quality, and profitability.
