The difference sulphur and L-α-amino acids makes in soyabeans

Sulphur (S) is a vital macronutrient ranking just after NPK. It plays a key role for protein synthesis, chlorophyll production, and photosynthesis, contributing to the production of starchers, sugars, oils, fats and vitamins. Additionally, Sulphur is essential for enzyme activation and formation of root nodules in legumes. The combination of Sulphur with micronutrients and L-α-amino acids makes the nutrients more bioavailable contributing to a stress relief, and to higher yields. Recent fie...

Enhanced Production by Terra-Sorb® Symbiotic Biostimulant in Two Model Species Under Nitrogen Stress

The increasing soil pollution has accelerated the implementation of new agricultural regulations that significantly limit the use of synthetic nitrogen (N) fertilizers. Consequently, plants are likely to experience nutrient stress, leading to decreased productivity and potential threats to food security. To address these critical challenges, microbial-based biostimulant (BS) products, which utilize metabolites from microorganisms, offer a sustainable and eco-friendly solution to mitigate pla...

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...
