Experimental Tests BETTER ROOTS DEVELOPMENT AND PHOTOSYNTHETIC EFFICIENCY

Fluid extract of yeast containing brown seaweeds, with amino acids of plant origin (20%) and micronutrients. Allowed in organic agriculture. - increased roots development - better photosynthetic efficiency - superior yields Hydro Gold Veg is a totally water-soluble organic nitrogen fertilizer, based on amino acids of plant origin, containing brown seaweed (Sargassum, Laminaria). Thanks to its particular composition, with a high and well-balanced content of free amino acids that can be rapidly absorbed, it can enhance the production of proteins, enzymes, plant regulators and sugars.

Plant extracts: precious allies of plants When regularly applied, Hydro Gold Veg is apt to achieve increased roots volume, homogeneous plant development, yields’improvement in terms of quality and quantity, as well as longer shelf life. In case of stress conditions (frost, hail, weeding, root asphyxia), it helps quickening the plant’s vegetative regrowth

Hydro Gold Veg increases the chlorophyll content (SPAD value) compared to the untreated control. This improves the phytosanitary status of plants, which become stronger against physical stress caused by frost or hail damages. FIG 3 - Average width and height of plants in two compared treatments. Hydro Gold Veg increases the height and width of plants compared to the untreated control, confirming the previous results which report a higher percentage of vigour. The free amino acids which can be rapidly absorbed favour a higher production of enzymes, plant growth regulators (PGR), sugars, proteins,...

ROOTS FRESH WEIGHT 60 FIG 6 - Fresh weight of roots in two compared treatments. Hydro Gold Veg improves the root system, proven by augmentations in width, length, fresh weight and volume values, compared to the untreated control, also thanks to its content of brown seaweeds. A more expanded root system allows a better absorption of nutrients and, therefore, a higher plant resistance against biotic and abiotic stress.

ROOTS VOLUME INDEX Hydro Gold Veg, thanks to its content of brown seaweeds and amino acids, favours a major roots expansion, thus resulting in a better use of the NPK supplied. Plants with a more expanded root system are stronger against biotic and abiotic stress. FLOWERS NUMBER FIG 3 - Average number of flowers per plot in two compared treatments. Hydro Gold Veg favours a higher flowers number per experimental plot, thus increasing the final producti
