In conversation with Dr J\u00fcrgen Kutscheidt<\/strong><\/h2>\n

Trees are currently in full leaf everywhere. Temperatures are pleasant and the sun is showing its best side. Road salt is probably the last thing on your mind right now. Yet it is precisely during this period that de-icing salt can cause significant stress for trees. The salt spread on roads and pavements in winter remains in the soil and continues to have an effect for months. And the consequences? They often only become visible in summer. Trees struggle to absorb water, causing leaves to remain smaller, develop brown edges, discolour and eventually dry out. <\/strong> As a result, many trees appear weakened and show reduced growth.<\/strong><\/p>\n

Strengthening trees in challenging conditions <\/strong><\/h2>\n

Dr J\u00fcrgen Kutscheidt <\/a>is a German researcher and consultant specialising in mycorrhiza and soil improvement. Since the 1980s, he has been studying and applying mycorrhizal fungi to strengthen trees in difficult growing conditions. Through his work in arboriculture, he focuses on maintaining and improving tree vitality, with mycorrhiza playing a key role. From this expertise, we asked him several questions about how mycorrhiza can help trees affected by salt stress caused by de-icing salt. <\/p>\n

Mycorrhiza for a stronger root system<\/strong><\/h2>\n

Mycorrhiza are beneficial soil fungi that live in symbiosis with tree roots. They extend the reach of roots, allowing trees to absorb water and nutrients more efficiently. This is particularly valuable under salt stress. Trees gain better access to what they need and can recover more effectively from adverse conditions. Dr Kutscheidt explains: \u201cIn principle, exposure to de-icing salt leads to the displacement of nutrients such as potassium, calcium and magnesium. These are then leached out, potentially causing nutrient deficiencies. In addition, the osmotic potential of the soil solution increases, making water uptake by the roots more difficult. The tree experiences drought stress and nutrient deficiency. This is where mycorrhiza come into play, supplying additional water and nutrients to the plant. We currently often use mycorrhiza inoculants suitable for high pH levels, as salt exposure can increase soil pH. In some cases, we combine this with specific mycorrhiza that better suit particular tree species, such as oak.\u201d <\/p>\n\t
