Detailed Description

Urban environments are often not optimal for trees. Abiotic stress factors can have negative impacts on growth, health and quality of the plants. To guarantee a good start and further development, careful planting is of great importance. To avoid soil compaction and to provide a good pore volume, mineral substrates with poor biological and nutritional value are usually used. The soil enhancers Agrosil^® LR and Agrosil^® Algin reduce stress; improve root development, microbial soil activity and the cation exchange capacity. To support a good start growth as well as a long lasting development, slow-release fertilizers are well suited for tree fertilization. Floranid^{® Twin} Baumkraft and Floranid^{® Twin} Permanent are well proven in practice as they contain the highly effective ISODUR^® and CROTODUR^® nitrogen, whose coating reduces the risk of leaching, plus amounts of tree friendly potassium and magnesium. Floranid^{® Twin} Baumkraft is also coated with Bacillus subtilis, selection E4-CDX^® to promote root development, nutrient availability and drought and disease resistance. In combination with irrigation and the treegator technique, liquid applications with e.g. Baumkraft^® Fluid or Vitanica^® RZ are also common. To avoid run off situations on the dry city soils and to optimize the usage of the nutrients, it is recommended to ad Kick^® wetting agent concentrate.
