The pollutant factors leading to disease in plants are of varied toxic origin. They also include the root and fine root system and the organisms involved in the circulatory system. Location, climate and environmental stresses are factors that play a key role in determining whether a plant flourishes or not. Ailing, frail plants are susceptible to secondary infestation (e.g. harmful insects, fungi, viruses). Plants treated with WALDLEBEN overcome all these stresses. Their growth in height and thickness and their biotically normal leaf and needle formation testify to this.
WALDLEBEN acts on the soil and is taken up by the plant via the roots, saturated bark or sprayed branches and leaves.
Following a single treatment with WALDLEBEN, debilitated cultures can overcome their obstacles to growth with the onset of the following growth period.

The mode of action of WALDLEBEN has been studied and described by various scientific institutions. The individual studies and appraisals can be downloaded in full from expert opinions.
The following description of WALDLEBEN’s mode of action is a summary of the results of various studies and appraisals.
Heavy metal trapping effect
WALDLEBEN transfers bivalent cations, e.g. heavy metals such as cadmium, zinc, mercury and copper, into insoluble compounds (complexation). With iron(II) the amino acids contained in WALDLEBEN formed stable flocculations even in the presence of humic substances, and these contribute to activation through soil bacteria. Antioxidants guarantee normal nutrient transportation to the roots and in the shoot.
Growth that was previously stunted recommences due to detoxification of the root environment.
Soil activating effect
WALDLEBEN activates the microbial soil life even on an inanimate substrate. The increase in soil activity, i.e. CO2 production due to mineralisation of easily decomposable organic substances by microorganisms, is clearly measurable. Mycorrhiza fungi are stimulated in addition to actinomycetes.
Its inhibiting effect on honey fungus and laetiporus sulphureus is documented in the appraisals.
Phytosanitary effect
WALDLEBEN brings about rapid colonisation of the soil constituents by various microorganisms. A simultaneous rapid multiplication of pathogens is thus suppressed (biological plant protection).
Effect on root and shoot growth
WALDLEBEN promotes the growth of roots and shoots by stimulating the metabolism of the plant through enzymatic activity. This causes:
an increase in the formation of small nodules and greater root length.
an increase in the number, and to a lesser extent the length, of shoots due to the activation of dormant buds. Stronger outward growth takes place.
an increase in the size and chlorophyll content of the leaves.
retarded ageing in the autumn (leaf fall).
an increase in the power of resistance to location-related growth factors, such as temporary dehydration and nutrient shortages, for example.
Wound-healing effect in the case of bark damage
WALDLEBEN aids wound healing on injured trees by promoting colonisation of the wound surface by certain microorganisms, while protecting against the ingress of wood-destroying fungi. As a result, the wound base remains intact and callus formation (healing-over) is more vigorous than on untreated trees.
Time scale for effect
The action of WALDLEBEN should be viewed as a long-term process over a number of months. Short-term effects occur only in relation to the complexation of heavy metals.
Environmental harmlessness
WALDLEBEN is quickly mineralised in microbially active soil. The ammonium component is very strongly pronounced here, so that nitrate is discharged from the soil only in very small amounts. The development of nitrifying bacteria (nitrobacter) is restricted by antagonists.
WALDLEBEN is assessed as epidemiologically harmless.
At the maximum dosage of 1 litre of WALDLEBEN per m² of soil it has been verified as harmless for use in water protection areas, protection zone II.
