1. Soil fertility characterization and mapping for Adigudem plain, Northern EthiopiaAs Ethiopia’s agriculture has been influenced by variability and poor soil fertility management and information, thus this study was aimed to determine the physico-chemical properties of soils and build geo-referenced soil information systems so as to have precision agriculture for adigudem plain. An area of 229 km2 comprising different villages was delineated for the study. Soil sampling points were arranged in a grid form and georeferenced using a hand-held GPS. A total of 194 Soil samples... G. Berhe |
2. Changes in climatic factors lead to the change in cultural wedging of rice in the Ivorian pre-forest zoneClimate change in the pre-forest zone of Cote d'Ivoire has led to a mismatch between cropping periods and new seasons, challenging the sowing periods usually recommended for rainfed rice cultivation in this area. Our study aims to determine the optimal sowing period for two rainfed rice varieties cultivated in this pre-forest zone of the country. The agroclimatic analysis carried out over the period 1980-2017 allowed to determine the optimal dates for sowing rice,... C. Brou |
3. Precision fertilizer management for soil fertility improvement in Sub-Sahara AfricaAttainment of food security remains one of the biggest challenges facing sub Saharan Africa. The continent continues to experience low production as a result of the low and declining soil fertility and land degradation, which have been compounded by unfavorable climatic conditions. Since the 1960s, there have been effort to transform the agricultural sector through promotion of diverse approaches of soil nutrient management. Research has demonstrated the potential and importance of fertilizers... A. Bationo |
4. Optimizing Durum Wheat Nitrogen Nutrition Index (NNI) Prediction Through Sentinel-2 Vegetation Index IntegrationNitrogen is crucial for durum wheat growth and productivity, but excess or insufficient levels can harm both the environment and farmers' finances. Remote sensing offers rapid, cost-effective, and nondestructive ways to assess crop nutrition, with vegetation indices (VIs) indicating plant health. This study aims to enhance the accuracy of durum wheat nitrogen status prediction by investigating modified formulations of Nitrogen Nutrition Index (NNI) coupled with various vegetation indices (VIs),...
