Sustane is so much more than a product line. Sustane is about producing only the best – the highest quality possible organic and natural based fertilizers. Sustane is about healthy growth through healthy soils. Sustane is a natural, biological recycling process made from renewable, agricultural resources that in the end optimizes new plant growth with the least possible inputs, the most savings in labor, time and money and the most favorable impact on the environment. Safe, slow, uniform, predictable release of nutrients when the plant requires. Organic based, long-lasting soil and plant fertility – that’s Sustane. Passion.
