The importance of nutrition
- Soil fertility is key to achieving global food security or sustainable agriculture.
- One of the most important tools for soil fertility is the use of fertilizers.
- The use of effective fertilizers and nutrition will lead to maximum production per unit area.
- Due to the continued harvesting and use of plant resources in the soil, it is important to pay attention to nutrition and the use of essential fertilizers.
Nutrients required by the plant that are used as fertilizer:
- Elements of primary consumption (macronutrients): nitrogen (N), phosphorus (P) and potassium (K)
- Secondary high-consumption elements: magnesium (Mg), calcium (Ca) and sulfur (S)
- Low-consumption or micronutrients (iron): iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), bar (B) and molybdenum (Mo)
The effect of soil conditions and reasons for lack of nutrients
- Alkaline soils with high acidity (pH) have led to the plant not having access to various elements.
- Many of the fertilizers used and nutrients in the soil are stabilized and virtually out of reach of the plant.
- Imbalance of elements, deficiency of micronutrients, carbonate and bicarbonate waters, low organic matter and high amounts of free calcium carbonate have caused a decrease and deficiency of nutrients.
- Clay soils restrict the movement of food, and sandy soils prevent food retention.
- Soils with low organic matter are deficient in phosphorus and molybdenum, and soils with high organic matter are deficient in manganese, copper and zinc.
Compatibility of Sepehr Parmis technology products with the soil conditions of the country
- Due to the acidity and low pH of the fertilizers produced, maximum absorption of elements in the soil is provided.
- Failure to stabilize the elements and the ability to absorb faster, more complete and higher nutrients in different parts of the plant.
- High percentage of purity and balance of elements in products improves efficiency and effectiveness.
The mobility of nutrients
- Elements N, P, K and Mg have motility in the plant and move from the old leaves to the younger and higher leaves. Because of this, the symptoms of deficiency of these elements first appear in the lower leaves.
- Ca, Fe, Mo, B, Cu, Mn, Zn elements do not have the ability to move in the plant, and therefore the symptoms of deficiency of these elements first appear in the upper and younger leaves.
Diagnosis of deficiency symptoms
- Identification and detection of deficiency symptoms is done by analyzing the soil, leaves and appearance of leaves and fruits. In different parts of the country, there is a severe shortage of some common elements, which helps to better identify the symptoms. Due to the lack of balance between the elements and the effects of the elements on each other, it is possible that several elements are missing at the same time and cause different and severe symptoms in plants.
- Deficiency symptoms can vary depending on the type of plant. However, due to the appearance of symptoms in the old (lower) or young (upper) leaves, there will be clear signs of the elements.
Interactions of elements on each other
- Elements that help absorb each other have a synergistic or stimulating effect, meaning that in the presence of one or more elements in the soil, the amount of absorption of the element or other elements increases.
- Elements that reduce the absorption of each other have a reducing or inhibitory effect. Inhibitory effects are negative, meaning that too much of one element in the soil may make it difficult to absorb another element.
- Examples of elements that have a synergistic effect:
- Phosphorus, magnesium and nitrogen on top of each other
- Manganese, potassium and iron overlap
- Examples of elements that have a deterrent effect:
- Phosphorus and iron elements on top of each other
- Phosphorus and zinc on each other
- Nitrogen and to each other
- High levels of calcium have a deterrent effect on phosphorus, zinc, magnesium, iron, manganese and potassium.
- High levels of nitrogen have a deterrent effect on potassium, copper.
Balance of nutrients
- Due to the synergistic and inhibitory effects of the elements, the balance and balance of nutrients must be considered depending on the type of plant and soil conditions. Therefore, excessive consumption of one element should be avoided because the more one element is used, the more the balance of the other elements will be damaged.
- The use of single-element fertilizers alone is valuable when done under expert supervision and with detailed analysis information, but in general it is recommended to use single-element fertilizers with combined fertilizers that include balanced ratios between macro and micro elements. To take.
Advantages of balanced formulation of Sepehr Parmis technology products
- Effective formulation with observance of synergistic elements for higher absorption of single-element fertilizers
- Observing a balanced and complete ratio of elements in the combined fertilizers produced (powdered fertilizer and liquid super micro-complete)
- Variety in the production of multiple compound fertilizers that allow the use of as a supplement along with the use of single-element fertilizers, chemical and organic fertilizers to increase the effectiveness and efficiency of common fertilizers.
