1. System-based Precision Agriculture for Sustainable Crop ProductionThe major challenge addressed is the systemic mismanagement of nitrogen (N) fertilizer in agricultural fields leading to problems such as leaching of nitrates into groundwater and emission of harmful greenhouse gases. Digital technologies are commercialized in agriculture (available from the early 1990s) but have failed with N fertilization. Despite agriculture is the least digitized sector (as highlighted at the last World Economic Forum) to make a reliable recommendation, researchers need to... D. Cammarano, S. Ata-ul-karim, M.

2. Use of a Chlorophyll Meter As a Decision-support Tool for Nitrogen Management in Coffee FieldsCoffee is a crop with high nitrogen (N) demand in Brazil; therefore, improving N use efficiency in coffee plantations can have significant environmental and economic impacts. Decisions regarding N application rates in coffee cultivation are often empirical or based on multiple factors, including expected yield and plant N status as determined by leaf N concentration. Traditionally, leaf N concentration is obtained through laboratory chemical analysis, a process that may take several days and limits... D. Almeida, M. Pereira, A. , V. Giroto, G. Portz |
