Description
It is a composition of trace elements with high rates. It can be taken quickly and easily by plants. It can be applied through the leaf and drip system in all vegetative
development periods. It is a special mixture fertilizer that meets the micronutrient needs of plants during the development, fruit formation and harvest periods, and
even after harvest.
It dissolves quickly in water and since it is completely EDTA chelated, it is quickly taken up by the plant and eliminates the deficiencies caused by microelements. During
the development phase of the plants, KEYSOL FOURTONER contains; Failure to eliminate zinc, manganese, iron and boron microelement deficiencies can lead to irreparable yield and quality losses.
Effects of the trace elements it contains on plant development:
IRON : It provides the energy transfer necessary for growth and chlorophyll synthesis, and is absolutely necessary for the transformation of chlorophyll.
ZINC : It triggers protein synthesis. It takes part in the transportation of carbohydrates and sugar. It is necessary for hormonal activities and auxin is the structural
element of the plant growth hormone. In its deficiency, vegetative development is prevented and the plant’s water intake slows down.
MANGANESE : It helps the formation of chlorophyll in the plant. It acts as a catalyst in enzymatic and physiological events in the plant. The plant organ most sensitive to
manganese deficiency is the chloroplast. In manganese deficiency, chloroplast formation is disrupted and cells shrink. Conversion into amino acids within the plant
stops. The sugar level of tissues and fruits remains low. Accordingly, the fruits do not taste sweet and remain small.
BORON : Cytokinin is effective in the synthesis of plant growth hormone, the formation of new cells and increasing the permeability of the cell membrane. It takes part
in the transport of calcium. It is necessary for seed formation, fruit set, pollen health and fertilization.
It supports flower and pollen formation by positively affecting the reactions that form flower physiology in plants. It has effects such as healthy flower formation, strong
flower stalk, high pollen amount, increased pollination, and quick awakening from stress conditions.
+ It facilitates the uptake of other macro elements in the soil.
+ Zinc, manganese and boron are important in flower formation in the shoot, fruit set, fruit growth and prevent fruit shedding.
+ By taking part in many enzyme structures in plants, it supports the plant to produce quality fruits as a result of photosynthesis.
+ It prevents the formation of chlorosis in plants.
+ Prevents stunted growth in plants.
