Optisol

Optisol is a leading specialist in plant nutrition in Switzerland. For more than 40 years, we have been processing litter from Swiss poultry production into high-quality fertilizers in Saillon/VS. Our organic raw materials come exclusively from Switzerland. We recycle them naturally, ensuring a closed, sustainable nutrient cycle. And we help to increase agricultural yields in a long-term and ecologically responsible manner.

In addition to our own products, we also carry various third-party products in our range: whether solid or liquid, from standard products to biodegradable specialty products, we offer the optimal solution for every crop. Our products are mainly used in agriculture, wine, fruit, and vegetable cultivation and are also ideal for private use. We also produce your individually tailored fertilizer "à la carte." We are ISO 9001 certified for reliable, consistently high quality.
