RAW Humic and Fulvic Acid Biostimulants 10lb

$440.00

More than 60 trace elements have been identified in humic acid and seaweed extracts, along with the chelating agents that make them readily available to the plant. “Beneficial” trace elements found in humic acid/seaweed, though not essential for plant growth, have positive effects on plant growth and vigor, and help the plant attain its full genetic potential. For example, silicon is not an essential element, but it helps strengthen leaf cells against fungal attack and improves the permeability of root cells to water and minerals. The judicious use of humic and fulvic acids may contribute to the nutritional value of fruits and vegetables, both directly through the addition of beneficial trace elements, and indirectly by improving the plant’s ability to take up and utilize both essential and beneficial elements.

Product description

The most concentrated, water soluble humic acid product on the market today is RAW Humic Acid which contains 59% Humic Acids derived from Leonardite. In nature, humic acid has a buffering effect on the pH of soils. It can raise the pH of acid soils and lower the pH of alkaline soils. RAW Humic Acid is great for hydroponics applications, especially when added to RO filtered water. RAW Humic acid is a natural chelator and is a beneficial supplement to all feeding schedules. A 2 oz package of RAW Humic Acid makes up to 200 gallons, an 8 oz package makes up to 800 gallons and a 2 lb package makes up to 3200 gallons.

Abstract This study was carried out on Aggizi cv. olive seedlings grown at greenhouseof National Research Center, Dokki, Giza governorate, Egypt. The investigation aimed to study the effect of bio stimulant based on algae extract, humic acid and mineral fertilizer NPK on vegetative growth and Leaf mineral content of Aggizi olive seedlings planted in plasticbags at nursery stage. After planting Aggizi olive seedlings, the following three treatments wereapplied as follows, T1: algae extractwith 1%which added at a rate of 0.5 liter per bag every 15,T2:humic acid as Actosal ( Humic acid 20% + NPK 1:5:6 ) which added at a rate of 4 cm3 per bag every 15 T3:combination ofNPK (20% N: 20% P: 20% K) at 45 g\plant\year divided into 16 equal doses about one dose every 15 day as applied as soil applicationand algae extractwith 1% which added at a rate of 0.5 liter per bag every 15from March to October. At the end of the season,percentage of plant height increment, leaf number per plant, shoot number per plant, stem diameter,leaf dry weight %, root number, root length, NPK Leaf mineral content were determined and recorded. The obtained resultsrevealed that using mineral fertilizer with 45 gm NPK /plant / year combined with bio stimulant based on algae extract (1%)gave the best results concerning lateral shoot numbers, Stem diameter,Leaves number,root numbers nitrogen, phosphor and potassium percentage. Whereas, algae extractalone achieved the highest plant height increment % lateral shoot numbers, Stem diameter, Leaves number, root lengthvalues. Regarding the effect of Humic acid data revealed that, with using humic acid alone, a Leaves dry weight %of Aggizi olive seedlings improved respectively.

Description

The greatest value of humic and fulvic acids are their roles as chelators. Humic and fulvic acids have functional groups that act as claws, holding mineral ions strongly enough to keep them from reacting with each other and becoming unavailable to the plant, but weakly enough so that they can be released to the plant cells on demand. Humic acid transports the minerals to the outside of the cell membranes, and releases the minerals for uptake by the plant. The fulvic acid fraction consists of small organic molecules that easily penetrate cell membranes. Fulvic acid transports minerals through the cell membranes and releases them directly to the plant cells.

INFLUENCE OF HUMIC SUBSTANCES ON THE GROWTH
OF MARINE PHYTOPLANKTON: DINOFLAGELLATES

ABSTRACT
Humic substances, in small amounts, exert a stimulatory effect on marine dinoflagellates
that is reflected in increased yield, growth rate, and ‘“C uptake. Humic acid was found
to be more active than fulvic acid; in both cases the growth responses were dependent
on concentration. Of the various fractions isolated, the low molecular weight fractions of
humic acid produced the greatest growth response in unialgal cultures of dinoflagellates.
The positive effect of humic substances on phytoplankton growth is, for the most part,
independent of nutrient concentration and cannot be attributed entirely to chelation
processes. It appears that growth enhancement in the presence of humic substances is
linked with stimulation of algal cell metabolism. Because of their high concentrations in
coastal waters, humic substances may thus be regarded as an ecologically significant entity
influencing phytoplanktonic prod&ion.
