Dear Colleagues,

Fertilizers improve plant growth by improving soil efficiency and changes in water retention and climate. Fertilizers usually contain substances in different proportions. Fertilizers are classified in several ways. They can be classified based on having only one nutrient. Combined fertilizers contain two or more different nutrients. Fertilizers are sometimes classified according to their nature (organic or inorganic). Organic fertilizers usually are plants (recycled) or taken from animals. Inorganic fertilizers are commonly referred to as chemical fertilizers because they require several chemical processes. Manufacturing Fertilizers in an industrial scale-up and in the framework of a project demands a certain pathway to be recognized in the implementation stage. Extracting nutrients and main materials from waste materials, waste residuals, and exploiting the raw materials or a combination of the alternatives sound economic viability in the manufacturing of fertilizers. But the question about; which one is efficient is uncertain concerning massive resources of raw materials in nature.

Thus, we are interested in the collective mentioned subjects in the framework of decision theory and green products sovereignty and competition, their internal strengthening processes, their operational strategies, their procedures about the biological products, and how technologies are generated and implemented.

For this, it is important to collect the experiences of manufacturing and cultivating different Fertilizers and Biological Products that have been implemented and considered their impacts and new achievements.

Research articles and reviews in this area of study are welcome. We look forward to receiving your contributions.
