Potential use of a new nitrogen trading tool to assess nitrogen management practices to protect groundwater quality

Potential use of cover crops for soil and water conservation, nutrient management, and climate change adaptation across the tropics

“…They end up increasing the N use efficiencies of these irrigated systems (Delgado, 1998(Delgado, , 2001Delgado et al, 1999Delgado et al, , 2001aDelgado et al, ,b, 2007a. Spatial variability in leaching, residual soil nitrate and N uptake was reported by Delgado (1998Delgado ( , 2001, who reported that these cover crops are an excellent tool to manage spatial and temporal variability of these irrigated systems, protecting groundwater quality (Delgado, 1998(Delgado, , 2001Delgado et al, 2020). The use of cover crops and rotations of deep-rooted crops with shallower-rooted vegetable crops in south-central Colorado contributed to protection of groundwater quality with an estimated mining (extraction) of 11.1 metric tons of NO 3 -N from groundwater since 2001, and an estimated increase in yields and higher N use efficiencies worth over $109 million (Delgado et al, 2020).…”

Conceptual Design of a Comprehensive Farm Nitrogen Management System

“…Rapidly developing sensing technology and data processing techniques have opened up new opportunities for realizing the knowledge-based control, regulation, and optimization of agricultural production processes [1][2][3]. Digital agriculture includes the innovation and application of digital nitrogen (N) management [4][5][6][7][8][9][10]. Recently, various digital tools have been developed for N management in agricultural production.…”
