Monitoring corn nitrogen nutrition index from optical and synthetic aperture radar satellite data and soil available nitrogen
(Springer, 2023-08)Nitrogen (N) nutrition index (NNI) is a reliable indicator of plant N status for field crops, but its determination is both labor- and cost-intensive. The utilization of remote sensing approaches for monitoring N, mainly ... -
Respiration of barley seeds (Hordeum vulgare L.) under different storage conditions
(Elsevier, 2023-09-01)The changes in oxygen (O2) and carbon dioxide (CO2) concentrations were characterized during the hermetic storage of barley seeds (Hordeum vulgare L.) in glass jars at different temperatures (5, 15, 25, and 35 °C) and ... -
Monitoring Corn Nitrogen Concentration from Radar (C-SAR), Optical, and Sensor Satellite Data Fusion
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-02)Corn (Zea mays L.) nitrogen (N) management requires monitoring plant N concentration (Nc) with remote sensing tools to improve N use, increasing both profitability and sustainability. This work aims to predict the corn Nc ... -
