Pre- and probiotic biostimulants for improving Nutrient Use Efficiency

The inefficient application of synthetic nitrogen (N) fertilizers has led to significant environmental pollution. Biostimulants offer a promising approach to mitigate issues related to N fertilization. This study aims to evaluate the impact of two biostimulants—a prebiotic and a probiotic—in compensating for deficient N fertilization. Specifically, we examined Terramin® Pro, based on L-α-amino acids and other biomolecules, and Terra Sorb® Symbiotic, combining L-α-amino acids and ...

Biostimulants: a tool to improve the aromatic composition of grapes

The compounds from the groups of terpenes, C13 norisoprenoids and benzene compounds are the main responsible for the aroma of the grapes, generally contributing floral and fruity notes to them. The foliar application in the vineyard of biostimulants is a proposed tool to increase the quality of the grapes.

Thus, in this work, a foliar application has been carried out on Tempranillo Blanco vines to increase its volatile composition, since, despite being a new variety with high oenolog...

Effect of L-amino acid-based biostimulants on nitrogen use efficiency (NUE) in lettuce plants

BACKGROUND: Biostimulants are increasingly integrated into production systems with the goal of modifying physiological processes in plants to optimize productivity. Specifically, L-α-amino acid-based biostimulants enhance plant productivity through improved photosynthesis and increased assimilation of essential nutrients such as nitrogen (N). This element is a major component of fertilizers, which usually are applied in excess. Thus, the inefficient use of N fertilizers has generated a seri...

A case study from Bioiberica: developing quality biostimulant products

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.

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

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...
