Evaluation of the performance of Terra-Sorb® granum in wheat under nitrogen limitation conditions: 3 years of experience

Field Experience | Terra-Sorb® | Extensive crops
The excessive use of nitrogen fertilizers in extensive crops has generated serious environmental problems, such as the contamination of aquifers and greenhouse gas emissions. This makes it necessary to implement alternative strategies, such as biofertilizers and biostimulants, that allow the reduction of synthetic nitrogen without compromising agricultural performance.
AIM:
In this context, the new Terra-Sorb® granum has been tested on Chambo wheat var. for a period of 3 consecutive years, with a focus on improving foliar nutrition through biostimulation, under conditions of reduction of 30 Fertilizing Units of Nitrogen (28UFN) in relation to regular fertilization in the area (58UFN) and comparing it with a commercial N2-fixing biofertilizer.
TREATMENT:
RESULTS:
Conclusion:
Over the three-year trial period, the application of Terra-Sorb® granum showed a significant increase in average yield compared to the control treatment (28 FFU) under the same nitrogen-limiting conditions. Furthermore, it outperformed the average yield of the fully fertilized control (58 FFU), achieving an average increase of +10.38%. This treatment also generated a Return on Investment (ROI) of 5.34, which represents significant profitability in cereal crops such as wheat.
