Organic-mineral fertiliser meets all the basic nutritional needs of plants, supplements the soil with organic matter and stimulates its microbiological activity. Farmers have long known that only healthy soil can produce a healthy and abundant harvest. Organic matter is derived from sapropel (natural lake sediments). Balanced fertiliser can be used for fertilising nitrogen-intensive and green leafy vegetables. The fertiliser can be used for cucumbers, bulb vegetables, herbs, lettuce, etc.
