Ultrasol®ine K Plus* provides the optimal amount of iodine to the crop

Most agricultural top soils and irrigation water contain very low concentrations of iodine, and it is often not available for plant uptake**

During 2022, water samples were collected in and around South Africa and analysed for iodine content. Thirty one out of 42 samples collected contained less than 1 micromole iodine per liter (µmol/L) of water (<0,13 ppm), with no correlation between content and location. Seven out of the remaining 11 were less than 2 µmol/L and the remainder less than 2,6 µmol/L. All were less than the proven iodine optimum in nutrient solutions of between 5 and 10 µmol/L.

A deficiency of iodine in plants is predicted to cause yield losses, similar to deficiency of any other plant nutrient. These are conclusions based on recent scientific research (Kiferle et al., 2021) supported by SQM, a company with a long history in providing the world with iodine and fertilizers from the Atacama desert in Chile.

This research enabled the lnternational Fertilizer Association (IFA) to add iodine in the list of beneficial plant nutrients in 2021. More recently, the fourth edition of Marschner’s Mineral Nutrition of Plants (ed. Rengel et al., 2022) refers to iodine as a beneficial element for plant growth, which meets the new definition of a mineral plant nutrient (Brown et al., 2022).

For optimal crop production, iodine should be supplied to crops at the right dosage. Ultrasol®ine K Plus contains two macronutrients essential for plants, potassium and nitrate nitrogen, and in addition, iodine.

Since potassium and nitrate nitrogen are applied in well-defined proportions, Ultrasol®ine K Plus also guarantees the administration of an adequate dose of iodine in all crop stages.

This makes it easy for the farmers to ensure the right amount of iodine in the nutrient solution, and to prevent excess uptake of iodine in leaves or fruits, simply by replacing the normal Ultrasol K Plus (KNO3 crystalline) with Ultrasol®ine K Plus in nutrient solutions, enhancing yield, quality and return on investment benefits.

Plants need iodine lodine is needed for:

Forty eight genes in shoots and 531 genes in roots are uniquely regulated by iodine in the nutrient solution. At least 82 proteins in leaves and roots contain iodine.

• Timely flowering and fruit production;

• Photosynthesis and sugar production = increased biomass;

• Root growth, defense from stress and calcium signaling.
