During the past two decades the presence of amino acid based biostimulants in the market has shown a steep growth. Many products have become available but, for many of them, a through analytical characterization of their composition has remained elusive.
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...
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...
In order to characterize the effect of the INICIUM® product, the aerial and underground development of pepper plants treated and untreated with the root application biostimulant was monitored. The results showed an incentive effect of growth in the post-transplant phase in plants treated with INICIUM®, which is visualized in an early growth of the root system. This effect seems to be associated with the production of thinner and longer roots that would provide a greater surface area of wat...
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 ...
