Organic biostimulants: an approach to their characterization and management within an integrated, sustainable and competitive agricultural strategy

November 2019
Bioestimulantes | Scientific articles | Terra-Sorb®

The following article shows the results of an exhaustive comparative study of both analytical characterization and agronomic efficacy of four biostimulant products based on amino acids from different sources of raw material (animal and plant origin) and methods of obtaining (chemical hydrolysis or enzymatic). Regarding the analytical characterization, the results show a greater degree of hydrolysis (greater amount of free amino acids) and a more complete and balanced amino acid profile of th...

Role of amino acid-based biostimulants to ameliorate crop damaging effect and increase efficiency of post-emergence herbicides in field crops.

Bioestimulantes | Posters | Terra-Sorb®

Post-emergence herbicides are commonly used to control weeds in field crops worldwide Depending on their crop selectivity, herbicides may cause crop adverse effects particularly under stress conditions, such as reduction of chlorophyll content, affection in photosynthesis performance and appearance of micronutrient deficiencies On the other hand, the application of amino acid based biostimulants have beneficial effects on crops reducing production losses caused by environmental stresses Howe...

Bioactive properties of biostimulants obtained by enzymatic hydrolysis

November 2017
Posters | Terra-Sorb®

Amino acid-based biostimulant is a commonly used category for those biostimulants that are obtained by hydrolysis of protein extracts. However, in addition to the content in L-Amino acids, they usually contain a complex matrix of several bioactive substances, including other organic-N compounds, mineral elements, carbohydrates, lipids, nucleotide derived metabolites and other compounds. This complex composition of bioactive components makes it difficult to ascribe a unique mode of action to ...

Photosynthetic Performance of the Imidazolinone Resistant Sunflower Exposed to Single and Combined Treatment by the Herbicide Imazamox and an Amino Acid Extract

October 2016
Scientific articles | Terra-Sorb®

The herbicide imazamox may provoke temporary yellowing and growth retardation in IMI-R sunflower hybrids, more often under stressful environmental conditions. Although, photosynthetic processes are not the primary sites of imazamox action, they might be influenced; therefore, more information about the photosynthetic performance of the herbicide-treated plants could be valuable for a further improvement of the Clearfield technology. Plant biostimulants have been shown to ameliorate damages c...
