Rutgers Univ.: Huma Pro® Stimulates Root Growth

Huma Pro® Stimulates Rhizophagy Cycle of Microbes to Increase Root Growth, Rutgers Univ.

Conducted by: James White, PhD, Rutgers University

Huma Gro® Products: Huma Pro®

OBJECTIVE

The purpose of this research project was to evaluate how humic acids stimulate microbial activity and initiation of the rhizophagy cycle (in which plants cultivate microbes on their roots and then absorb them to extract their nutrients). Huma Gro® Huma Pro®, a liquid 6% humic acid product, was used as the humic acid biostimulant source.

MATERIALS AND METHODS

Huma Pro®, a 6% liquid humic acid, was incorporated into agarose at concentrations of 0%, 0.01%, and 0.10% humic acids. Seeds of tall fescure, annual bluegrass (Poa annua), and beefsteak tomato were surface disinfected in 3% NaOCl for 30 minutes to reduce microbial load on seedlings. Seeds were germinated and grown for 6 days on agarose (a polysaccharide derived from seaweed) with and without the Huma Gro® product.

CONCLUSIONS

Huma Pro® promotes seedling development in the seedlings tested. Root length in seedlings treated with Huma Pro® increased 73% (tomato) to almost 300% (tall fescue), roots growing downward increased 7 percentage points (tomato) to almost 75 percentage points (bluegrass), and shoot length increased 80% for tall fescue. Huma Pro® acts to stimulate the root microbiome and shows evidence of stimulating the rhizophagy cycle. Stimulation of the rhizophagy cycle in plants should result in increased nutrient absorption in plants.

Humic Acid Biostimulant Research by BHN Humic R&D Lab Scientists Published in Int’l Agronomic Journal

In its May 2021 issue, Frontiers in Plant Science published a research article by BHN Humic R&D Lab scientists Dr. Hiarhi Monda, Ryan Fountain, and Dr. Richard T. Lamar in collaboration with Dr. Amy McKenna of the National High Magnetic Field Laboratory, Ion Cyclotron Resonance Facility, Tallahassee, Fla.

The research, titled “Bioactivity of Humic Acids Extracted from Shale Ore: Molecular Characterization and Structure-Activity Relationship With Tomato Plant Yield Under Nutritional Stress,” revealed an unprecedented level of molecular characterization made possible by means of ultra-high resolution ion cyclotron mass spectrometry, providing a more comprehensive understanding of individual components of humic substances involved in enhancing plant productivity.

A detailed characterization of chemical composition becomes critical as new government regulations of biostimulant products will require the elucidation of the mode of action in order to supply farmers with effective product claims based on science.

The objective of this study was to investigate in detail the chemical features of humic acids (HAs) extracted from sedimentary ore with the aim of exploring the potential relationship of chemical functions with biostimulant activity and to evaluate the extent to which the priming effect of HAs on tomato plants under nutritional stress was reflected on the yield gains. 

The results of this study proved the biostimulant efficacy of humic acid application that improved nutrient use efficiency and at the same time alleviated the nutritional stress condition. All tomato plants treated with humic acids showed faster adaptation to stress conditions, particularly when nutrient deficiency occurred. Plant growth and tomato yield increased when provided with humic acids under low nutritional doses, and tomato fruit quality was improved under all humic acid treatments.

The increased antioxidants production under humic application has been correlated to the presence of specific molecules in the humic extract. These molecules, such as quinones and flavonoids, can act as both antioxidants and pro-oxidants that can trigger the plant defensive system, ultimately leading to a fast and effective response to nutrient deficiency with a consequent enhancement of plant morphology and productivity.

Among the study’s conclusions are that plant pre-conditioning with humic substances might represent an important determinant in the adaptive plant defense response and an effective strategy to improve nutrients management and plant yield.

Liquid Sili-Max® Improves Wheat Yield at Much Higher Efficiency Than Conventional Dry Silicon Fertilizers

Research by Brenda Tubana, PhD, Louisiana State University

The objective of this study was to compare, for use in Louisiana wheat production, the efficacy of a liquid silicon (Si) fertilizer (Huma Gro® Sili-Max®) with a commonly used dry Si source (steel slag) and another Si source (wollastonite) often used in research as a suspension. Silica deposition is an important barrier for foliar fungal diseases.

The wheat field study was conducted at Louisiana Ag-Center Research Stations. Silicon (Si) treatments were replicated four times and arranged in a randomized block design. There were 2 Huma Gro® Sili-Max® (10% Si) treatments (as a foliar band, and as foliar broadcast sprayed evenly over the entire plot). Each treatment was applied twice within 2 weeks at the onset of internode elongation (Feekes growth stage 5). The dry silicon sources (wollastonite [23% Si] and steel slag [11% Si]) were applied and incorporated into the soil prior to planting. Wheat leaf samples were collected one week after the application of silicon solution sources and evaluated for silica bodies (phytolith) deposition and percentage using scanning electron microscopy and energy dispersive x-ray analysis.

Sili-Max® foliar band and Sili-Max® foliar broadcast increased grain yield by 10 and 7 bu/ac, respectively, in reference to the control plot (Fig. 1). It is important to note that the total silicon applied using Sili-Max® solution was substantially lower (0.064 to 0.128 lb Si/ac) than the dry wollastonite and steel slag silicon sources (250 lb Si/ac). The state average wheat yield was low that year due to a mild winter that affected the wheat vernalization. Sili-Max® foliar band had the numerically highest straw yield at 7,941 lb/ac.

The accumulated silica bodies (phytolith) were 0.69% and 0.60% with Sili-Max® foliar broadcast and Sili-Max® foliar band treatments, respectively while the control had 0.53%.

Conclusions
Huma Gro® Sili-Max® applied as foliar band at a rate 3,900 times less than the dry silicon sources contributed to higher grain yield and straw yield, while the application of Sili-Max® as a foliar broadcast at a rate 1,900 times less than the dry silicon sources led to high Si deposition in wheat leaves.

SUPER PHOS® and SUPER NITRO® Improve Spring Wheat Grain Yield and Quality

Research by Olga Walsh, PhD, University of Idaho

The objectives of this study were (1) to compare the Micro Carbon Technology®-based phosphorus (P) product Super Phos® (SP) with traditional phosphorus (P) fertilizers ammonium polyphosphate (APP), and diammonium phosphate (DAP); and (2) to compare the Micro Carbon Technology®-based nitrogen (N) product Super Nitro® (SN) with the traditional nitrogen fertilizer, UAN.

Huma Gro® Super Nitro® followed by 30 lb P2O5 per acre of Super Phos® (Treatment #3) contributed to the highest grain test weights, biomass, and yield.

This study also indicates that Super Phos® is less corrosive and less likely to cause damage to the seeds as a dribble and suggests that Super Phos® could be applied with the seed at a higher rate compared with other P sources.

Sili-Max® limita la absorción de arsénico en el arroz

Informe de investigación

Realizado por: Lic. Luisella Celi, Universidad de Torino, Italia

El arroz (Oryza sativa) es el alimento básico para más de la mitad de la población mundial, y alimenta a unos 3.500 millones de personas. Sin embargo, en comparación con otros cultivos, el arroz acumula mayores cantidades de arsénico (As) dado que se cultiva en campos anegados bajo condiciones anaeróbicas. El arsénico es un elemento tóxico y carcinógeno.

Por lo tanto, disminuir los niveles de As en el grano de arroz, en especial las formas inorgánicas más tóxicas (As [III] y As [V]), es uno de los principales objetivos de productores y legisladores. La Comisión Europea acaba de establecer un límite de contenido de As en el arroz comercial de 200 µg kg-1 para el arroz blanco y de 100 µg kg-1 para el arroz para bebés. Por consiguiente, es fundamental establecer prácticas agronómicas adecuadas para reducir la acumulación de As en el arroz.

Una práctica prometedora es la aplicación de fuentes de silicio (Si), ya que el Si compite con la absorción de As a nivel radicular. Hay muy pocas fuentes eficaces de silicio en el mercado que limitan la absorción de As por parte de las plantas. Por lo tanto, es necesario identificar fertilizantes eficaces que son seguros para el medio ambiente y la calidad del alimento.

En este estudio, Huma Gro® Sili-Max® demostró su capacidad de aportar a las plantas de arroz Si disponible y, al mismo tiempo, disminuir el contenido de As inorgánico del grano mucho más que las otras fuentes de Si sometidas a prueba. Sili-Max® demostró ser una fuente de SI prometedora no solo por suministrar Si, sino también por limitar la absorción de As inorgánico, uno de los elementos más tóxicos de los productos de arroz, por parte de la planta.

Sili-Max® Limits Arsenic Uptake in Rice

Research Report

Research Conducted by: Luisella Celi, PhD, University of Torino, Italy

Rice (Oryza sativa) is the staple food for more than half the world’s population, feeding about 3.5 billion people. Compared with other crops, however, rice accumulates higher amounts of arsenic (As) due to its cultivation in flooded fields under anaerobic conditions. Arsenic is a toxic and carcinogenic element.

Decreasing As levels in the rice grain, particularly the more toxic inorganic forms (As [III] and As [V]) is, therefore, one of the main objectives of rice producers and policymakers. The European Commission has recently set a limit of As content in commercial rice to 200 µg kg-1 for white rice and to 100 µg kg-1 for baby food rice. Hence, it is essential to establish appropriate agronomic practices for reducing As accumulation in rice.

A promising practice is the application of silicon (Si) sources, since Si competes with As uptake at the root level. There are only a few efficient silicon sources in the market that limit As uptake by plants. Therefore, it is necessary to identify efficient fertilizers that are safe for the environment and food quality.

In this study, Huma Gro® Sili-Max® demonstrated its ability to supply rice plants with available Si while decreasing inorganic As content in the grain more significantly than the other tested Si sources. Sili-Max® proved to be a promising Si source not only for supplying Si but also for limiting plant uptake of inorganic As, one of the most toxic elements in rice products.

Promax® Efficacy in Controlling Strawberry Pathogens

Plant Sciences, Inc., conducted an independent study to test the efficacy of Promax® for inhibiting mycelial growth of 8 fungal strawberry pathogens through in vitro bio-assay. The following 8 fungi and fungal-like pathogens were tested:

Botrytis cinera
Colletotrichum acutatum
Cylindrocarpon destructans
Fusarium oxysporum f. sp. fragariae
Macrophomina phaseolina
Phytophthora ramorum
Rhizoctonia solani
Verticillium dahlia

After 1 week of incubation, all 8 pathogens tested were completely inhibited from mycelial growth in media amended with 2% Promax® (see photos, pages 2 and 3). After 2 weeks, 7 of the 8 pathogens were still 100% inhibited. Verticillium dahlia began to grow a little after 2 weeks; the mean percentage inhibition of V. dahliae was 94% after 2 weeks (Figure 1).
