Generating soil salinity, soil moisture, soil pH from satellite imagery and its analysis

Information Processing in Agriculture, 2020
In an agricultural field, the water content and salt content are defined as soil moisture and soil salinity and have to be estimated precisely. The changing of these two factors can be assessed using remote sensing technology. This study was conducted by

African Twist of Circular Economy: Insights, Policies and Recommendations

Business Strategy and the Environment, EarlyView.
ABSTRACT While the circular economy (CE) has gained traction, this paper argues that mainstream CE approaches risk being misaligned in the African context. Drawing on a mixed‐methods synthesis of empirical studies, policy documents and cross‐country examples, the study shows that Africa's CE transition is fragmented and uneven, leaving the continent at

Genetic switch to lower nitrogen fertilizer dependency and enhance maize yield

iMetaOmics, EarlyView.
Transcription factor NCR1 regulates nitrate transporter NRT2.3 and controls root‐to‐shoot nitrogen transport. A superior NCR1 haplotype, lost in modern maize breeding, boosts this process. This discovery enables breeding and biotechnology to develop high‐yielding maize varieties that require less nitrogen fertilizer, reducing agricultural costs and ...

Multiobjective Simulation–Optimization of Crop Allocation and Water Resources in Canal Command Areas Using Genetic Algorithms

Irrigation and Drainage, EarlyView.
ABSTRACT This study develops an integrated simulation–optimization framework for sustainable crop allocation and water resource management in the Bargarh Canal Command (BCC), eastern India. Efficient irrigation allocation remains a critical challenge due to competing demands, groundwater–surface water interactions and environmental constraints ...
