  • SHORT PRESENTATION
  • A modern and sustainable agriculture involves the use in appreciable quantities of fertilization products to be applied in various forms (liquid, solid, radicular, foliar). It is well-known that from this delivered quantities, only a small part is absorbed by plants in an useful way, significant quantities of fertilizers being washed in unusable areas or degraded by environmental factors, before being absorbed by plants, these having a limited capacity of rapid intake of mineral nutrients. On the other hand, use of exaggerated quantities of mineral fertilizers leads inevitably to the appearance in culture plants of significant quantities of chemical products derived from these fertilizers (nitrates, nitrosamines etc), that can be found inherently in the foods, affecting the health of population, so having an extremely powerful impact over environment.

    Taking into account the necessity of reducing the impact of use of chemical fertilizers over the alimental quality of vegetal production, the Project proposes modern formulations obtained through particulate methods of encapsulation of fertilizers, with slow release of active substances, in order to be entirely metabolized by plants and minimize the risk of soil and environment contamination with metabolic by-products (nitrozamines and nitrozoderivates). Therefore, it is estimated a significant diminution of the quantities of fertilizers necessary to be applied per surface unit and avoidance of appearance of byproducts in culture plants, as effects of overdoses.

OBJECTIVES

The specific objectives of project are elaboration, testing and homologation of minimum two original compositions of chemical ecological fertilizers, with controlled-release activity, prepared by encapsulation of the fertilizing raw-materials into polymeric microcapsules, by interfacial policondensation. Two innovative technologies will be developed to be transferred to SME’s pilot scale for manufacture of slow-released fertilizer compositions. The experimental techniques of application and appropriate doses of fertilizers will be optimized in order to improve their bioavailability in plant tissues and to reduce the influence of the perturbing environmental agents.

Another objective of the project is to strengthen cooperation among research institutions and SMEs from different EU countries, interconnection of research structures (team and equipment) to achieve competitive research structures at European level in specific research areas.


MAIN STAGES OF PROJECT
  • Foundation of R&D strategy and experimental model elaboration for microencapsulated fertilizers production
  • Validation of the lab-scale experimental model to optimize formulations and technologies, design projection of the pilot plant for manufacture of microencapsulated fertilizers
  • Demonstration the functionality of original technical solutions in the experimental pilot plant
  • Identification and transfer of the innovative technical solutions for the manufacture of original slow-release microencapsulated fertilizers to the SME
  • Information, dissemination of the Project results and publicity regarding the Project

ESTIMATED RESULTS

1. Economical impact of the project
The development of new types of microencapsulated fertilizers with controlled release, obtained with reduced consumption of raw materials and energy will generate a favorable economic impact concretized in the economic growth of the units with profile of production of mineral fertilizers, starting with the SME partner. The position on the market of these units will be improved, occupying a top position on the market of slow-release fertilizers. The dissemination of results will lead to the identification of new potential beneficiaries. This will lead to the improvement of the performances and competitivity of SMEs, concretized by the growth of rate of turnover and profit, development of the technological capacities. The experience accumulated in the Project will stimulate them to continue the activity by implementation of innovative technologies and development of new portfolio of products for industrial platforms.

2. Social impact of the project
Having great chances of implementation on industrial level of production, the innovative technologies will generate the need of new workplaces. Participation in the Project of research teams from units with production profile able to implement the results, will lead to the growing of their own capacity for research and development, also to consolidate the international cooperation between innovative SMEs. The final products of the project are destined to the production of ecologic crops free from toxic compounds resulted from known mineral fertilizers used in conventional agricultural practices. The positive social impact is obviously better conditions of work and life, because the consequence implies at least the diminution of professional sickness risk for the manufacturers and farmers and in life quality improvement for the consumers.

  3. Environment impact The application of the project results will have a positive impact over the environment, such as an important diminution of risks of accumulation in the agro-products of now-inherent wastes from the chemical fertilization process, the original formulations of slow-release fertilizers having lower doses of use comparative to the classic ones and the best intake by the plants.
