Also, it is an important source of Flavonoids, known as antioxidants, which remove free radicals that damage tissue cells within the body. Bio-fertilizers are products containing multiple genera of microorganisms in large numbers and beneficial to both plants and soil in an integrated manner. In addition bio-fertilizers have proved that increase the nutrient content inside plants, whether in leaves or fruits,which is reflected in the quantity and quality of fruits and also balance the ratio between plant nutrients in the soil.
