High-consumption elements include nitrogen (N), phosphorus (P), pistachio shell potassium (K), calcium (Ca), magnesium (mg) and sulfur (S), and trace elements include iron (Fa), manganese (respectively). Mn), chlorine (Cl), bar (B), ms (Cu), zinc (Zn), nickel (Ni), molybdenum (Mo). The elements carbon (C), hydrogen (H) and oxygen (O) are also high consumption elements because their initial supply and absorption is mostly done through air, except for the initial division.
In some classifications, the elements sodium (Na), cobalt (Co), and silicon (Si) are considered to be rarely necessary elements (elements that are present in small amounts necessary for the growth of some plants) and very small amounts of elements such as iodine. (I), fluorine (F), bromine (Br), aluminum (Al) and selenium (Se) are considered to stimulate plant growth, but say that although they have no role in plant nutrition, but for the health of plant consumers (humans and Animals need to be present in adequate amounts in plants.
Nutrients are usually absorbed by water-soluble ions or by diffusion from the soil to the surface of the roots and are absorbed. With enough food, other symptoms may limit the growth of the tree and cause symptoms to be confused with the symptoms of malnutrition. These factors include:
Soil dryness or lack of moisture in it
Wounding of tree trunks with mechanical devices
Application of herbicides
Accumulation of some foods under certain conditions
To identify deficiencies in pistachio trees, all conditions must be considered together. Therefore, deficiencies can be identified only by the appearance of signs that the other needs of the tree are fully met.
