Chemical fertilizers are the indispensible inputs of contemporary agricultural production. Fertilizer dressing has an essential role in yielding high quality product in large quantities. It has been observed by researches that application of fertilizer by optimum kind and amount would help productivity increase by 50 per cent in many areas even the other conditions are kept without any improvements.

There are seventeen elements which are essential for growing plants. The first ten of them are indispensible, and deficiency of these elements would cause extensive loss of productivity and quality. Carbon, hydrogen and oxigen, three of these essentials, have been obtained from water and atmosphere. In case of inadequacy of other elements, which are Nitrogen (N), potassium (K), calcium (Ca), magnesium (Mg), phosphorus (P), sulphur (S), ferrum (Fe), zinc (Zn), cuprum (Cu), manganese (Mn), boron (B), molybdenum (Mo), chlor (Cl), natrium (Na), the soil should be supplied with them by way of fertilizing.
Nitrogen, phosphorus and potassium, which are the basic nutrients for plant grow, are manufactured in Turkey, and imported from other producing countries as well. These main fertilising agents are provided in chrystal, prill and granular forms, and supply well-balanced nutrition to the plants by their availability, sprinkle conveniency and various compositions.
The soil tends to become poorer in many regions due to intensive cultivation and agricultural productivity lessens by time. BAGFAS manufactures and imports quality fertilizers needed for the plant growing.
To achieve a high-quality and affluent crop it is best to have the soil analysed, to specify the proper type and amount of fertilizer and to apply the fertilizer at the right time. The process is to be completed by the right decision of type, amount and timing of top dressing in accordance with the results of leaf analysis.
