Deficiency correctors are fertilizers designed to correct specific nutrient deficiencies in crops. Our range covers micronutrient fertilizer products, chelated micronutrients and secondary nutrients such as calcium and magnesium. At Quelagrow, we develop a complete range of correctors to ensure that every plant gets the essential nutrients it needs to grow strong and healthy. Our products are designed with warehouses, wholesalers and distributors in mind who are looking for effective, high quality solutions for their customers.
Deficiency correctors are products formulated to correct nutrient deficiencies in plants.
These deficiencies, whether of micronutrients such as iron, zinc or manganese, or of macronutrients, affect crop health and yield.
Deficiency correctors allow the nutritional balance of plants to be restored quickly and effectively, optimising growth and crop production.
The right nutrient deficiency treatment for plants starts with the symptoms: chlorosis on young leaves when available iron is short, blossom end rot, bitter pit or tip burn linked to calcium, or bleached, necrotic leaf tips when copper is lacking. A soil or tissue test confirms which nutrient is limiting and the most effective way to apply it.
Our multiple deficiency correctors are formulated to provide a combination of essential micronutrients that may be lacking in the soil or in the plant. This ensures balanced nutrition and prevents the occurrence of multiple deficiencies that can affect crop performance.
We offer formulated correctors for specific deficiencies such as iron, zinc, manganese, calcium, copper and molybdenum. Each of them is designed to treat a specific deficiency and provide quick results in the crop.
As a micronutrient fertilizer manufacturer with our own plant in Almería, Spain, we supply correctors in liquid and solid form to fit each application method. Liquids such as QUELAFERT® MICROS-L are easy to dose and do not clog fertigation filters. Soluble solids such as QUELAFERT® MICROS S or QUELAFERT® CINC-MANGANESO S carry more nutrient per kilo and work in fertigation, hydroponics or foliar sprays.
By correcting nutritional deficiencies efficiently, deficiency correctors significantly increase the yield and quality of agricultural production.
Our correctors act quickly, ensuring nutrient uptake by the plant and resolving deficiencies that, if left untreated, can have a severe impact on productivity.
Nutritional deficiencies affect the plant’s resistance to pests and diseases. Correcting these deficiencies contributes to the overall health of the crop, promoting greater resistance to external problems.
The use of deficiency correctors allows the effect of the base fertiliser to be optimised, ensuring that each nutrient is absorbed efficiently and in the right quantities.
We produce deficiency correctors in sufficient quantities to meet the demand of distributors and warehouses.
We offer customised packaging that facilitates the distribution and handling of the product by our customers.
Each type of deficiency corrector is designed to solve specific deficiencies, providing an effective and rapid response.
Our team will help you select the right corrector according to the type of crop and the needs of the agricultural area.
A multiple deficiency corrector contains several essential nutrients that may be lacking in the soil, making it ideal for correcting various deficiencies simultaneously. On the other hand, a specific corrector is formulated to treat a specific deficiency, such as iron or zinc, and is more suitable when a clear and specific deficiency is diagnosed.
Deficiency correctors should be applied as soon as signs of deficiency, such as chlorosis, reduced growth, or loss of leaf colour, are detected. Applying them in time will prevent a drop in crop productivity.
The appropriate dosage depends on the type of deficiency corrector, the crop and the severity of the deficiency. In general, it is advisable to follow the manufacturer’s instructions and to carry out a soil or plant analysis to determine the exact amount.
For citrus, correctors containing zinc, manganese and iron are usually effective, as these micronutrients are commonly deficient in this type of crop. Applying a suitable corrector ensures healthy production and quality fruit.
In a chelate, the nutrient is bound to a chelating agent (EDTA or EDDHA) that protects it from soil pH and keeps it available to the plant: our EDDHA iron chelate is stable between pH 3 and 11. In a complex, the nutrient is bound to organic molecules such as polycarboxylic acids or ethanolamine, which make it easier to absorb, as in QUELAFERT® CALCIO or QUELAFERT® BORO.
Yes. QUELAFERT® BORO, QUELAFERT® SorbCa, QUELAFERT® ECOCUAJE and QUELAFERT® CINC-MANGANESO L and S are certified by Sohiscert for organic farming under EU regulations. You can see the full range in our organic fertilizers section.
