LENA COMBI is a mixture of chelated micro-elements using ethylene diamine tri-acetic and citric acids. It is easily absorbed by the plant.

LENA COMBI treats and resists effectively the yellowish problems appear as a result of micronutrients deficiency.

LENA COMBI is rich with organic acids, amino acids and vitamins that activate the plant and increase its growth.

LENA COMBI contains special additions and distributing materials increase the plant ability to use the micronutrients.

LENA COMBI provides fresh leaves and increase plant resistance to frost and weather changes.

LENA COMBI can be absorbed by leaves in case of foliar application or by roots when added by soil.

LENA COMBI used for protection and treatment of nutrient deficiency. In case of protection, the minimum rate used while for treatment maximum rate is used.

For the protection of micronutrients deficiency it is recommended to use LENA COMBI in the vigor growth stages and after the fruiting stage.

The composition of the micronutrients is a distinguished one due to its content of all micronutrients in balanced ratio proper for plant growth. The micronutrient are chelated such away it achieve optimum benefit with the antagonistic effect among the elements. It is recommended in case of mix deficiency of micro nutrients.

When the deficiency appears on the plant, LENA COMBI should be used soon. Its usage should be used in case of deficiency repeat every week or two weeks according to the needs.

The disuse of the mono-micronutrients evolves the antagonism effect. When treating the deficiency symptoms, the addition of Fe may cause the Mn, Zn and Co deficiency. The treatment of Zn deficiency may evolve the deficiency of iron. So, it is proper to use balance formula of the micronutrients LENA COMBI to get the best results.

To avoid deficiency symptoms which affect production directly, specially the latent deficiency which affect the vegority of the plant and the production, it is recommended to use LENA COMBI regularly to avoid deficiency.

LENA COMBI can be use effectively through foliar application

LENA COMBI usage many times through the growing season saves the needs of the crop of the chelated micronutrients which moves simply from the leave to the internal and from cell to another with the juice, then to the rest of plant parts. So, the foliar application is considered the best method to add LENA COMBI due the following reasons:

–         The simple absorption and the move the LENA COMBI elements from the leaf surface to inside the plant.

–         The use of the added amounts completely which increase the fertilization efficiency.

–         The fast method to recover the deficiency of micronutrients through the high growing periods.

–         More efficient in providing the short seasonal crops such field crops and some vegetables.

–         Less cost as the LENA COMBI can be added as a part of the protection program. So, many sprays can be deleted for the micro-elements.

–         Foliar application of LENA COMBI solves the variation in soil fertility as it saves the crop needs of the micronutrients through the foliar application without solving the fertility problems inside the farm.

–         Foliar application of LENA COMBI helps in getting red of stabilizing the micronutrients in soil
