Experimental tests WITH HIGH % OF HUMIC ACIDS

Humic 16 PRODOTTO AD AZIONE SPECIFICA ESTRATTI UMICI DA LEONARDITE PRODUCT WITH SPECIFIC ACTION HUMIC EXTRACTS FROM LEONARDITE PRODUIT AVEC ACTION SPECIFIQUE EXTRAITS HUMIOUES DE LEONARDITE PRODUCTO DE ACCION ESPECiFICA EXTRACTOS HUMICOS DE LEONARDITA It is a biostimulant based on humic extracts from leonardite, containing a high concentration of fast-acting humic acids. Such elements are essential for the soil because they’re able to enhance the Cation-exchange capacity (CEC), thus improving both the availability of nutrients and the efficiency of fertilization. - better roots development -...

Overcoming water and saline stress and improving soil texture Hydro Humic 16 helps plants to overcome water and saline stress, thus increasing yields, too. Humic and fulvic acids improve soil texture by positively influencing both drainage and water retention, besides enhancing the Cation-exchange capacity (CEC) and the absorption of nutrients. Therefore, plants can grow in an optimal way during all the phenological phases of their agricultural cycle.

Experimental results Lettuce in greenhouse MATERIALS AND METHODS Species Lactuga sativa var. Romana Experimental design Factorial at fully randomized blocks Test duration 62 days Temperature 4–31 °C Relative humidity 30-95% Substratum 93,3% sandy / 3,2% clay / 3,5% loamy Method of administration Fertigation Compared treatments 2 biostimulant treatments Control (1) and Hydro Humic 16 (4) 20 l/ha 3 salinity levels ( S1 S2 S3 = 0,48 dS/cm, 3 dS/cm, 5 dS/cm) 3 water stress levels ( I1 I2 I3 = no stress / medium stress / high stress) Number of applications 2: 15/10/2020 (pre-transplanting) and 5/11/2020...

VEGETATIVE PART IMG 1 - Vegetative development of lettuce plants in two compared treatments. FRESH WEIGHT OF ROOTS 30 23,31 29,48 g FIG 2 - Average fresh weight of roots per plant, after 62 days from transplanting, in two compared treatments. Fulvic and humic acids in Hydro Humic 16 enhance a bigger production of roots primordia and hair, compared with Control. Therefore, its biostimulant activity develops a stronger roots system, able to explore a wider portion of the rhizosphere. FIG 3 - Average dry matter of roots per plant, after 62 days from transplanting, in two compared treatments. Hydro...

ROOTS VOLUME INDEX ROOTS WIDTH FIG 4 - Roots volume index, after 62 days from transplanting, in two compared treatments. FIG 5 - Roots width, after 62 days from transplanting, in two compared treatments. The application of Hydro Humic 16 results in higher values of roots volume and width, compared with the Control. More vigorous roots give plants a stronger resistance against biotic and abiotic stresses. VIGOUR WITH STRESS ROOTS WITH STRESS FIG 6 - Average vigour, after 27 days from transplanting, in two compared treatments, under saline and water stress conditions. CONTROL HYDRO HUMIC 16 S3...

DRY MATTER WITH STRESS FIG 7 - Average dry matter, after 62 days from transplanting, in two compared treatments under saline and water stress conditions Hydro Humic 16 increases the production of dry matter, even under saline and water stress conditions, thus resulting in bigger yields.

HEINZ 1538 Experimental design Fully randomized blocks Test duration 14 weeks: 13/05/2019 (transplanting) – 23/08/2019 (end of trial) Temperature According to the climate trend in the countryside of Trinitapoli (Italy) Relative humidity According to the climate trend in the countryside of Trinitapoli (Italy) Light Typical of the trial period Substratum Sandy and loamy soil Method of administration Fertigation Compared treatments Number of applications Control and Hydro Humic 16 (20 l/ha) 3...

FIG 2 - Average NDVI (Normalized Difference Vegetation Index) per plant, in two compared treatments Hydro Humic 16 increases both vigour and photosynthetic efficiency of plants, thus improving their phytosanitary status, making them stronger against biotic and abiotic stresses. YIELDS FIG 3 - Average yields per plant, in two compared treatments. The use of Hydro Humic 16 increases the average yields per plant. That's because the humic and fulvic acids inside it allow a bigger accumulation of reserve substances.

FRUITS FRESH WEIGHT 70 0 59,7 65,5 g FIG 4 - Average fruits fresh weight per plant, in two compared treatments. FIG 5 - Average fruits size per plant, in two compared treatments. The application of Hydro Humic 16 allows to obtain bigger yields, with fruits showing a higher fresh weight as well as a wider diameter, compared with the untreated control. 09

ROOTS FRESH WEIGHT 60 70 FIG 6 - Average roots fresh weight per plant, after 69 days from transplanting, in two compared treatments Humic and fulvic acids contained in Hydro Humic 16 favour a greater development of radical hair. Therefore, a wider roots system, with a remarkable fresh weight, will be able to absorb the nutrients in a more efficient way.
