At KIOSHI STONE SA, we are pioneers in implementing industrial nanotechnology processes for agriculture. With extensive experience in R&D, we continuously create innovative tools that support high-yield farming with minimal logistics and an almost imperceptible carbon footprint (CO2-eq), compared to other farming technologies.
Our products significantly improve soil health (biota); their immediate interaction and synergistic effect with ecosystems result in high yields across all types of crops (both extensive and intensive). By increasing biological activity, we promote the healthy development of plants.
At KIOSHI STONE, we continuously evaluate the benefits of using nanometric-sized minerals, leveraging their high reactivity and low energy requirements in crucial biological processes like soil reactions and photosynthesis. By participating in these processes at natural scales (size, light, energy, and time), our products act as biocatalysts, enhancing these complex reactions and promoting sustainable agricultural development.

Greenhouse + Research
R&D is the heart of KIOSHI STONE. Our multidisciplinary team focuses on nanotechnology, particularly on minerals and biological sources. Equipped with state-of-the-art laboratories, we develop agricultural tools to enhance soil health, nutrition, and plant protection.
Our development areas focus on nanotechnology, particularly on minerals and biological sources. We are equipped with state-of-the-art laboratories that allow us to tackle a wide range of applications.
These applications primarily focus on developing tools for agricultural production, with products aimed at improving soil health, plant nutrition, and protection. Over the past year, we have begun research in collaboration with specialized groups in Galicia (Spain) and Mar del Plata, studying the application of nanoparticles as a nutritional supplement in mussel production.
Another area is biological, where we have jointly developed a patent with CONICET for the production of amino acids, polypeptides, and growth promoters using microorganisms. This technology offers a platform for applications that will lead to high-value products for the industry.
Finally, in our crop area, we have state-of-the-art laboratories and greenhouses where we can simulate different productive environments. This area focuses on developing species for hydroponic production and multiplying a wide variety of plants, both ornamental and for intensive production.
Additionally, we have collaboration agreements for research with national and international institutions across Argentina, the LATAM region, and recent studies in the U.S.

Production + Factory
Kioshi Stone operates three production plants: two dedicated to the liquid product line "Mist" and a third focused on microgranulates.
Our production processes are ISO 9000 certified and include modern equipment for nanoparticle emulsions and nano-encapsulation processes.
The microgranulate plant features unique German granulation technology, the only one of its kind in the country. All three plants are fully automated, ensuring optimal quality and production capacity.

Technical Field
In these fields, we conduct a wide range of tests to evaluate the performance of our fertilizers under different soil, climate, and crop conditions. We have carefully prepared land plots, divided into sections, for comparative studies to ensure precise results.
Our technical talks play a key role in spreading knowledge and education in the agricultural sector. Through these sessions, we share specialized insights, research, and innovative practices with farmers, industry professionals, and others interested in sustainable agriculture and food production.
What We've Achieved
With our MIST and BIOME fertilizers, we not only significantly increase crop yields but also enhance soil structure by regulating pH levels, improving nutrient availability, and promoting organic matter conservation. This is achieved with a notable reduction in the traditionally used doses, thanks to the superior catalytic activity and diffusion of nanoparticles.
An additional benefit lies in the reduced logistics needed for both transportation and application. For example, MIST can be applied even when crops are in an advanced vegetative state, unlike traditional liming systems, which require significant machinery, cause soil compaction, and must be done before planting. MIST, on the other hand, can be sprayed or combined with phytosanitary products using easily accessible rural equipment, streamlining operations.
For our BIOME line, even lower doses are required compared to traditional microgranules, offering important logistical advantages. Furthermore, this method does not cause phytotoxicity, making it an eco-friendly choice. BIOME can be applied directly to the sowing line, maximizing its efficiency and making its use more convenient for farmers. This innovative approach enhances both environmental sustainability and agricultural productivity.
