The influence of two biostimulants on leaf gas exchanges and leaf characteristics of English oak (Quercus robur L.) was evaluated in a urban environment over two growing seasons. Trunk diameter and shoot growth were also monitored. Treatments included 1) control (no biostimulants); 2) Root Grow WP, a commercial hydrosoluble powder made of a mix of humic acids, marine algae, Yucca extracts, vitamins, amino acids, and nitrogen-fixing bacteria; and 3) Mycobacter DP, a commercial granular mix of… 

Effect of controlled inoculation with specific mycorrhizal fungi from the urban environment on growth and physiology of containerized shade tree species growing under different water regimes

The overall data suggest that inoculated plants were better able to maintain physiological activity during water stress in comparison to non-inoculated plants.

Effects of an Animal-Derived Biostimulant on the Growth and Physiological Parameters of Potted Snapdragon (Antirrhinum majus L.)

To assess the effect a new animal-derived biostimulant on the growth, root morphology, nitrogen content, leaf gas exchange of greenhouse potted snapdragon, three treatments were compared: (a) three

Humectants as Post-Plant Soil Amendments: Effects on the Wilting Cycle of Drought-Stressed, Container-Grown Tree Seedlings

To test the potential effectiveness of humectant-containing compounds for improving soil moisture availability in the rhizosphere of newly transplanted trees, one-year-old Jiffy Plug™ and bare-root

Effect of Humisol on Survival and Growth of Nursery Grafted Walnut ( Juglans regia L.) Plants

Soil application of Humisol led to better performance of nursery grafted plants, compared to foliar application, and nursery plants receiving 1.5 ml Humisol per year through both soil and foliarApplication exhibited the best performance in the parameters analysed.


Results show use of biostimulants can improve root and shoot vigour following transplanting, however, selection of an appropriate biostIMulant is critical as effects on growth and vitality can vary widely between tree species possibly as a result of the differing active ingredient used in the formulated product.

Biostimulants Promote Plant Development, Crop Productivity, and Fruit Quality of Protected Strawberries

Berries such as strawberries are recognized as a significant constituent of healthy human diets owing to their bioactive secondary metabolites. To improve crop sustainability, yield and berry

Evaluation of Borage Extracts As Potential Biostimulant Using a Phenomic, Agronomic, Physiological, and Biochemical Approach

Borage extracts appear to indeed exert biostimulant effects on lettuce; future work will be required to further investigate on their efficacy in different conditions and/or species.

The use of biological liquid fertilizers against oak decline associated with Phytophthora spp.

Worldwide, multiple ecosystems are currently affected by global change because of important anthropogenic disturbances which have quickly increased levels of abiotic (e.g. climate) and biotic stress

The use of biological liquid fertilizers against oak decline associated with Phytophthora spp.

Investigation of the effect of soil improvement through soil biological fertilizers on oak defense against tree decline symptoms associated with Phytophthora for two ontogenetic stages of oak trees found fertilized plants were more attractive to herbivores, probably as a result of the greater content in deficient minerals, increasing their palatability.

Humectants as Post-plant Soil Amendments: Effects on Growth and Physiological Activity of Drought-stressed, Container-grown Tree Seedlings

One-year-old seedlings of red maple (Acer rubrum L.) and yellow poplar (Liriodendron tulipifera L.) were treated with Hydretain ES™(HydES) or EcoSential™(EcoS) applied as a soil drench. A progressive
