Micronutrients
Cr, Zn, Cu, Pb, Co, and As trace elements were stronger inhibitory effects on soil biological properties. The enrichment of these trace elements in agriculture soil samples conforms their higher input of trace element contaminated organic manures, synthetic fertilizer, and fungicides by the farmers
Some trace elements, including copper (Cu), zinc (Zn), manganese (Mn), iron (Fe), molybdenum (Mo), and boron (B) are essential to plant growth and are called micronutrients. Except for B, these elements are also heavy metals, and are toxic to plants at high concentrations.
Some trace elements of potential concern as soil contaminants are: arsenic (As), boron (B), cadmium (Cd), chromium (Cr), copper (Cu), fluorine (F), lead (Pb), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), selenium (Se), and zinc (Zn).
During the past century our knowledge of trace elements and their importance in crop and animal nutrition has grown steadily
The different types of trace elements
The main trace elements within organic fertilizers are: • Molybdenum (Mo); Plays a role in the functioning of various enzymes, growth and nitrogen balance of the plant and contributes to the production of various plant hormones. • Copper (Cu): Important for the formation of proteins, vitamins, carbohydrates and enzymes of the plant. Copper strengthens the cell walls of the plant and improves resistance. • Zinc (Zn): Optimes the development of leaf green, stalk elongation and plant veins. The plant will build up better resistance. • Iron (Fe): Plays a role in the production of leaf greenery, respiration of the plant and it contributes to the capture of nitrogen in the roots of the plant. • Boron (B) and manganese (Mn); Most known trace elements which we describe below. Manganese for photosynthesis and metabolism of the plant
Manganese plays a role in photosynthesis, in many enzymes and contributes to the plants’ metabolism and cell division. Manganese is a building material of, among other things, enzymes. Because of this the plant will becomes stable and strong.
With a deficiency manganese, the plant can become more susceptible to fungal diseases. A defect causes yellow spots between the veins in the leaf (because manganese is sensitive to acidity (pH). Furthermore a defect reduces the growth of roots and affects the leaf green. A deficient acidity can become toxic. In short, a shortage of manganese disrupts various processes that ultimately impair the development of the plant. Role of Boron
Boron plays a role during the production of cell extension in the roots and in cell division. Boron supports the production of enzymes. These enzymes organize cell division and this contributes to a good development of young shoots. Boron also contributes to the construction of the vessels and the transport system for water and minerals in the plant.
On the other hand, a lack of boron can be caused by a poor soil structure, a surplus of nitrogen and / or potassium in the soil or a too low pH value. Micro and Macro nutrients
In organic fertilizers you will find relatively less micro nutrients compared to macro nutrients, like N-P-K and calcium and magnesium. But both are important for different processes and together they all contribute to a healthy soil and higher yield of the crops. Nutrients in organic fertilizers
Organic fertilizers keep the soil healthy, the soil life alive and contribute to a sustainable world. We AK Industry import this product from DOW CROP UK. We are the recognized Reseller in Pakistan.
