“…The use of controlled release devices is increasing in the horticultural sector. In this way, products to release water [ 1 ], fertilizers [ 2 ] or pesticides [ 3 ] can be found in the market, improving their efficiency in crops. Generally, these devices are made using polymeric coatings that contain the substance to be released.…”

The union of nanoscience (nanofertilization) with controlled release bioplastic systems could be a key factor for the improvement of fertilization in horticulture, avoiding excessive contamination and reducing the price of the products found in the current market. In this context, the objective of this work was to incorporate ZnO nanoparticles in soy protein-based bioplastic processed using injection moulding. Thus, the concentration of ZnO nanoparticles (0 wt%, 1.0 wt%, 2.0 wt%, 4.5 wt%) and mould temperature (70 °C, 90 °C and 110 °C) were evaluated through a mechanical (flexural and tensile properties), morphological (microstructure and nanoparticle distribution) and functional (water uptake capacity, micronutrient release and biodegradability) characterization. The results indicate that these parameters play an important role in the final characteristics of the bioplastics, being able to modify them. Ultimately, this study increases the versatility and functionality of the use of bioplastics and nanofertilization in horticulture, helping to prevent the greatest environmental impact caused.

It is estimated that up to 50% of conventional fertilizers are lost once applied to agricultural soils (i.e., due to leaching and/or evaporation) or remain in the matrix due to poor nutrient use efficiency (NUE) by the crops. Controlled-release fertilizers (CRFs) might overcome both issues, and the use of extracted biobased polymers (or biodegradable materials) from organic waste (e.g., food losses or agrowaste) as coating agents is an ecological alternative aligned within the concept of a circular economy. This review is divided into two main sections: (i) sustainable CRF production (i.e., organic residues, value-added polymers used as capping agents, encapsulation methods) and (ii) a description of the nutrient release mechanism (i.e., a brief overview of nutrient release models applied to CRFs, and to the biodegradation process). The information provided in this manuscript will be relevant to guide future research in the field with the aim of promoting a sustainable approach in the use of fertilizers as well as other agrochemicals in agriculture.

The nutrient release from conventional chemical fertilizers to the soil are lost continuously through leaching, runoff, volatilisation, denitrification etc and also most of the time they do not satisfy the plant requirements without the continuous application. These issues have caused economic loss as well as environmental pollution due to hazardous emissions and water eutrophication. Controlled release of nutrients through the application of slow/controlled release fertilizers and nanofertilizers are possible solutions, which provides their nutrients according to the requirement of crops. Release of nutrients from controlled release fertilizers are delayed by means of coating the soluble fertilizer core with porous semipermeable membrane. A variety of coating materials are developed for the preparation of controlled release fertilizers. The longevity of controlled release fertilizers (CRFs) depends upon the thickness of coating, temperature and moisture content. Nano technology is an emerging field, which also produce nanofertilizers based on CRFs are used for the increment of active fertilizer material in the field, as they present large surface area for the release of required nutrients to the plant in a controlled manner. Controlled release of nutrients has profound influence on soil properties and yield parameters of crops. The use of controlled release fertilizers (CRFs) starts to evolve as a promising direction offering an excellent means to improve management of nutrient application and by this reducing significantly environmental threats while maintaining high crop yields of good quality. Controlled release fertilizers allow the release of nutrients to be better matched with the life cycle of the plant.
