ENProducts
OPTA's agricultural input lines are developed to nourish the soil before nourishing the plants, promoting a fertile, balanced, and biologically active environment. Products such as Bokashi, TerraPlant, biological fertilizers, algae-based solutions, BIOCHAR, and other highly efficient additives work synergistically to improve the rhizosphere microbiota—the region where roots interact intensely with the soil.
With bio-based technologies and sustainable solutions, our portfolio is designed to regenerate the soil, increase nutrient availability, and promote healthier plants, resulting in greater productivity and profitability in the field — today and in the future.
BOKASHI® ingredients are produced using carefully selected raw materials, combined in a balanced way to undergo a controlled fermentation process.
The BOKASHI® line consists of liquid organic fertilizer (FERT BOKASHI), granulated organic fertilizer (NUTRI and MASTER BOKASHI), and substrates made with organic materials (PLANT and GARDEN BOKASHI).
The TERRAPLANT line of fertilizers consists of high-quality organic inputs, derived from controlled fermentation of poultry litter from broiler chickens, and is registered with MAPA (Ministry of Agriculture, Livestock and Supply).
The MULTISOLO® base product is composed of more than 501 TP3T of organic matter, in addition to being an exceptional source of micro and macronutrients for various crops. This line consists of the following products: MULTISOLO® (granulated fertilizer), GRANUPLANT® (granulated fertilizer), and MINERPLANT® (organomineral fertilizer).
Regenerative Fertility for Soil and Plants
BIOCHAR is a highly efficient fertilizer developed to regenerate the soil, increase nutrient availability, and stimulate root development. Its biotechnological formulation improves the physical structure of the soil, enhances water retention, and promotes greater beneficial microbial activity. The result is a more vigorous, productive, and sustainable crop—a modern solution for producers seeking agronomic performance with environmental responsibility.
Advanced Nutrition and Physiological Stimulation
Produced from seaweed extracts, these fertilizers offer a complete package of natural biomolecules, plant hormones, amino acids, and minerals. Their action stimulates plant metabolism, promotes root development, improves tolerance to climatic stresses, and enhances productive response.
With strong sustainable appeal and excellent performance in different crops, algae-based fertilizers are strategic allies for more efficient, resilient agriculture with high agronomic value.
