The urea transporter DUR3 is differentially regulated by abiotic and biotic stresses in coffee plants. Author(s): PEREIRA, L. F. P. The high costs of N fertilizers in the coffee production emphasizes the need to optimize fertilization practices and improve nitrogen use efficiency. Urea is widespread in nature, characterizing itsel... ... Repository: BDPA Publication year: 2021
Enhanced-efficiency fertilizers in nitrous oxide emissions from urea applied to sugarcane. Author(s): ANDRADE, C. A. de Abstract: The environmental benefits of producing biofuels from sugarcane have been questioned due to greenhouse gas emissions during the biomass production stage, especially nitrous oxide (N2O) assoc... ...
