This category includes products which are used to improve crop nutrition by nourishing the soil with the required elements and biological activity. This will contribute to a healthy and balanced plant growth in terms of:

• Preventing microelement deficiencies
• Improving soil structure
• Stimulating vegetative plant growth
• Enhancing root growth

Within this group there are two types of products. On one hand, the ones which fulfil the EU Regulation 2092/91 for Organic Agriculture and in addition have been approved by an independent certification body (see the respective logo). On the other hand, the products that in spite of being totally natural and innocuous cannot be included under the same regulation.

All these products can be identified in green colour, which is also present on the label. In relation to their mode of action these products can be divided in 3 subcategories: Soil improvers, plant stimulants and nutrient deficiency amendments.
