A Review of Secchi’s Contribution to Marine Optics and the Foundation of Secchi Disk Science

open access: yes, 2020
Angelo Secchi was an astrophysicist and a pioneer in the use of spectroscopy in that field and also contributed to meteorology and geodesy. His only contribution to oceanography was on the physics of the “Secchi disk,” a simple device that provides a ...

Modelling the Impact of Drained and Undrained Conditions on GHG Emissions in Croplands: A Case Study in Lincolnshire, UK

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Agricultural drainage plays a crucial role in land management and crop productivity but significantly impacts greenhouse gas (GHG) emissions. This study examines the effects of drained and undrained soil conditions on GHG emissions in croplands via a case study in Lincolnshire, United Kingdom.

Assessing environmental and management factors that drive soybean yield gaps in Brazil

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Brazil is the world's largest producer and exporter of soybeans (Glycine max L. Merr.). Assessing yield gaps (Yg) is essential for improving resource use efficiency and guiding farmers’ management strategies. The objective of this study was to estimate soybean yield potential (Yp), water‐limited yields (Yw), and Yg based on water and ...

Seasonal variability of nitrate concentrations below the root zone: A monthly predictive modeling approach

open access: yesJournal of Environmental Quality, EarlyView.
Abstract Nitrogen Leaching Estimation System version 5 (NLES5) is an empirical model extensively used for estimating annual nitrate leaching from the root zone. The model is based on leaching data obtained by multiplying the measured nitrate concentration below the root zone depth by the percolation calculated using a hydrological model, which together

An Innovative Approach to Effective, Impact‐Driven Partnering: An Educational Aid Case Study

open access: yesJournal of International Development, EarlyView.
ABSTRACT Cross‐sector collaborations are prevalent mechanisms for delivering international development aid. Effective collaboration efforts among partner organizations can drive aid and programme impacts. Nonetheless, many development aid scholars and practitioners highlight weak interpartner and contextual dynamics as predominant reasons for ...
