Selected inputs for your crops

Natsource offers fertilizers, biostimulants and soil improvers tailored to meet the specific needs of your crops. Natsource inputs provide the right balance of essential plant nutrients, promote healthy growth, stimulate plants and maximize yields.

Biostimulants are substances that improve abiotic stress resistance and crop health, and promote root growth and flower and fruit development. Soil conditioners are added to the soil to improve its physical properties, such as fertility, structure and water retention capacity. Fertilizers provide nitrogen, phosphorus and potassium, with an NPK adapted to the crop's stage of development. They also correct micro-nutrient deficiencies.
