About This Special Issue
Ever since the value of inorganic elements was identified as one of the levers of increasing crop production, fertilizer experiments have opened the way for more crop yields. As more production requires the removal of more nutrients from the soil, it will be necessary to consume more fertilizers in the future to continue production. On the other hand, increasing population and decreasing per capita agricultural land, has found its way in supplying shortage of fertilizers to feed Unbalanced use of fertilizers, in particular the excessive use of nitrogen and phosphate fertilizers in vegetable and safflower products, in addition to increasing the accumulation of NO3 and Cd in them decreased the concentration of vitamin C by 26%. On the other hand, studies have shown that the molar ratio of phytic acid to zinc (PA / Zn), which is an indicator of nutrient absorption in the digestive system of the body, is more than 50% in the traditional method of fertilization in wheat grain. Over use of phosphorus in the soils has resulted in their accumulation in the surface layer which reduces yield due to the high phosphorus ratio to zinc or phosphorus to iron, accumulation of boron, molybdenum and cadmium in plant tissue, plant phosphorus poisoning and reduction of seed protein and reduced marketability of agricultural products. Due to unscientific culture and consumption of fertilizers especially urea and ammonium phosphate, in addition to the economic damage caused environmental problems and pollution including: destruction of building and soil texture, enrichment of surface waters by drainage discharge from leaching of fertilizers nitrogen, phosphorus and potassium, nutrient escape into drainage, poor soil acidification performance, decrease in soil biological activity, loss of soil physical properties, lack of micronutrients in NPK fertilizers. The use of biological fertilizers as an alternative way to chemical fertilizers is currently being proposed to increase soil fertility in sustainable crop production. Biological fertilizers are useful soil organisms that are capable of rapidly decomposing plant residues to convert nutrients from unabsorbed form to soil remediation, soil amendment and more. Bacteria are among the soil microorganisms that are involved in the nutrient cycle of the soil and can improve plant growth and are known as growth promoting bacteria (PGPR). Therefore for development safe agriculture product using experiences other researchers in the world will open the new windows for crop producers.
