In general, copper deficiency is not very common due to the presence of copper in many medicines. However, deficiencies can be seen in lands newly opened to agriculture, especially if the organic matter content is high. This is because organic matter absorbs copper very strongly. is the binding. Sometimes high levels of other microelements also cause copper deficiency.

   Copper is necessary for the formation of chlorophyll. It is a catalyst for respiration, regulates carbon dioxide intake, and for these reasons, it is a very effective element in photosynthesis. When the content of copper in the plant body drops below normal, generative development in plants is more affected. Deformation in flowers, discoloration, lack of flowers, no flowers at all. Failure to form or flowering may be observed. There is a decrease in the formation of amino acids and enzymes.

   Copper deficiency, like other microelements, first occurs in young people. It is seen on the leaves. Çübecause&uum; copper is not mobile within the plant.

   Copper's Functions in Plants

· It is necessary for the formation of chlorophyll. It regulates carbon dioxide uptake and is effective in photosynthesis. · It is found in the structure of many enzymes. It is important for protein production.

· It is a catalyst for respiration. · It helps balance the water movement in the plant.

· It takes part in the formation of the cell wall.

· It is necessary for normal flower formation and seed production.

Copper Deficiency Symptoms

· Youngç Yellowing of the leaves, sometimes whitening or gray-green appearance, and in advanced cases, drying.

· Yellowing at the tips of the shoots, in advanced cases, drying or backward death.

· Bushiness, dwarfing, decrease in heading in plants.

· Flower deterioration, discoloration, lack of flowers, flower dropouts or no flowers at all. not to occur.

· Cracking in fruits, premature ripening and falling of fruits.

· Root formation decreases. Root development is prevented.

Conditions That Reduce Copper Uptake

· Alkaline, calcareous, high pH soils.

· Soils with high organic matter content that are newly opened to agriculture.

· Low copper amount in the soil.

· Proportional excess of other trace elements. Especially iron (Fe), zinc (Zn), manganese (Mn), molybdenum (Mo).

· Cold and rainy weather conditions.

· High application of nitrogen or phosphorus.
