The increase in the amount of cultivation use per hectare causes a rapid exhaustion of soil nutrients. Fertilising simply replenishes the macronutrients (nitrogen, phosphorus and potassium), nevertheless, all crops require a series of elements which are only present in small quantities in the soil - micronutrients such as iron, manganesium, zinc. If a plant is lacking micronutrients, or these are not found in a nutrient availability form e.g. having formed non soluble precipitates, then the normal development of the plant will be altered. In fruit trees, the lack of iron causes the leaves and buds to turn yellow (chlorosity) whilst copper deficiency leads to leaf rot and reduces the quality of the fruit. In the case of maize, the lack of copper provokes the desiccation of leaf tips and the lack of zinc causes a drop in bud growth. To prevent and correct these deficiencies, S.A. DABEER offers a full range of micronutrient chelates:
-KELANTREN, DABIRON, and DABEERSEN iron chelate range.
-DABQUELAN zinc, manganesium, copper and cobalt chelate range.
-DABQUEL magnesium and calcium chelate range.
-DABQUEL-MIX micronutrient’s mixture range.
DABEERSEN products are also used to stabilise water-soluble herbicides and to prevent the formation of compounds between the herbicide and the metallic ions found in water.
