Fertilization and Sustainability
The search for more efficient and sustainable fertilizers remains a key challenge for the agricultural industry. One technological strategy invovles combining nitrogen sources with nitrification inhibitors, offering added value when derived from natural origins. Another challenge for the sector is the development of new fertilizers with efficient micronutrients that are effective for crops while remaining environmentally stable, preventing losses through leaching or rapid degradation. In the case of nanofertilizers, their high nanopartical surface area may represent a greater potential for their phytoavailability. However, it is important to rule out their potential phytotoxicity. On the other hand, integrated studies of agricultural systems that consider soil tillage managament, the selection of species and cultivars in crop rotations, and the inclusion of cover crops- serve as powerful tools for achieving more economically and environmentally efficient agircultural systems.
CEIGRAM provides various avenues for collaboration with companies, researchers and stakeholders from the sector to support the transition to a more productive and sustainable agriculture.
