Fe deficiency is marked by pale green and yellow color of the youngest leaves, while the veins remain darker green (intercostal chlorosis). Sometimes the youngest leaves contain no chlorophyll at all and are white in color then.
Iron deficiency Iron deficiency mainly occurs in calcareous soils and in other soils with a high pH-value due to the low availability of Fe. In specific clay soils Fe becomes fixated and deficiency is the consequence.
Potatoes: Apply 2-5 kg/ha through the watering system. Repeat as required to correct/prevent iron deficiency – up to rates of 40 kg/ha. Use enough water to wet the top 10 cm of the soil. Use clean water immediately afterwards to wash the iron chelate from the foliage.Read more about YaraTera REXOLIN Q40
