Disadvantages of using Nano-particles as fertilizers in Iraq

Abstract

The agriculture around the world faced many difficulties and the important was to reduce inputs of chemical fertilizers and pesticides and increase the total yield specially with the continuous grow of populations numbers at the world expected to reach more than 9 billion by 2050. In other hand there are other problems which make the challenges bigger such as wars, biotic and abiotic stress, and diseases. The scientists tried to find solutions by using Nano-fertilization which consider a modern way to quickly grow up the yield and decrease use the chemicals. The use of nanotechnology may be destructive on human and the environment due to fast accumulation in the tissues of alive bodies which obligate the researchers to find the correct method and doses of Nano fertilizers for the different plants beside the attempt to use fertilizer environment friendly with high efficiency on growth and yield. Many products of nanotechnology were used in agriculture as fertilizers, pesticides, and water purification and while these products use expand, we need to make our steps fast to be careful of the advantages use which may appears in the future on human health and his environments. In Iraq there is many of challenges faced plant production such as wars, migrations, pollutions, and salinity so a lot of farmers found that Nano-fertilizers are a good technique to reduce their loss while there are many studies cautioned of bad use of nanomaterials which its dangerous is bigger than chemicals due its ability to permeability and accumulations.
