Real-world environmental problems are typically vast, urgent, and complex. Confronted with such problems, we are often tempted to act fast by pulling together little bits and pieces from different fields and simply adding these to pre-existing models and frameworks. Seldom, though, do we pause long enough to look whether and for how long those larger structures we build can support reliable [...]

Protecting fish and farms: incentivising adoption of modern fish-protection screens for water pumps and gravity-fed diversions in Australia

Tom Sutherland Rayner, John Conallin, Craig A. Boys, et al.

Published: 2023-02-17
Subjects: Agriculture

Modern fish-protection screens offer significant potential benefits for Australia. The Commonwealth and New South Wales (NSW) governments have invested over $30m to incentivise early adoption by water users. However, successful adoption requires an understanding of the motivations and abilities of water users, and strategies to overcome key barriers to adoption. Four practices have been used in [...]

Solar irradiance distribution under vertically mounted agrivoltaic systems – Model development, validation, and applications for microclimate assessment

Pietro Elia Campana, Jonathan Staaf Scragg, Silvia Ma Lu, et al.

Published: 2022-11-21
Subjects: Agriculture, Power and Energy

ccurate assessment of the Photosynthetically Active Radiation (PAR) and Global Horizontal Irradiance (GHI) at the crop level is paramount for accurately assessing the energy balances and the crop yield under agrivoltaic systems. The shadings produced by the photovoltaic modules and structures of the agrivoltaic systems cause a non-homogeneous distribution of PAR and GHI at the crop level. It is [...]

FIELD LEVEL VARIATION INFLUENCED OUTCOMES MORE THAN N-FERTILISER, FYM, COVER CROPS OR THEIR LEGACY EFFECTS FOLLOWING CONVERSION TO A NO-TILL ARABLE SYSTEM

Subjects: Agriculture, Biogeochemistry, Earth Sciences, Environmental Chemistry, Other Earth Sciences, Other Environmental Sciences, Soil Science

Crop establishment in no-till arable systems benefits from favourable soil conditions. Combined with the incorporation of crop residues and manures, no-till can influence soil organic carbon (SOC) and organic matter (SOM) dynamics, crop productivity and nutrient cycling. These processes are shaped by spatial and temporal factors and associated microbial processes. There is a lack of diachronic [...]

The study focused on measuring the impact of the INTA-Chinandega rice variety on the rate of production increase in 40 farms in the North Pacific region of Nicaragua. Data from INTA Pacific North was used and covered the 7 production cycles. The DEA approach was used as a non-parametric programming method to calculate the Malmquist productivity indices. The results showed that the INTA Chinandega [...]

Majority of 21st century global irrigation expansion has been in water stressed regions

Piyush Mehta, Stefan Siebert, Matti Kummu, et al.

Published: 2022-08-09
Subjects: Agriculture, Spatial Science, Sustainability

The expansion of irrigated agriculture has increased global crop production but resulted in widespread stress to freshwater resources. Ensuring that increases in irrigated production only occur in places where water is relatively abundant is a key objective of sustainable agriculture, and knowledge of how irrigated land has evolved is important for measuring progress towards water sustainability. [...]

Field’s Spatial Variation Influenced Outcomes more so than N-fertiliser, FYM, Cover Crops or Their Legacy Effects Following Conversion to a No-till Arable System

Subjects: Agricultural Science, Agriculture, Agronomy and Crop Sciences Life Sciences, Environmental Indicators and Impact Assessment, Soil Science, Sustainability

No-till in agricultural arable systems is a practice that offers benefits to soil health. Combined with methods such as the incorporation of crop residues and manures, no-till can influence the dynamics of soil organic carbon (SOC) and organic matter (SOM), crop productivity and nutrient status. These turnovers are shaped by spatial and temporal factors and associated microbial mineralisation [...]

Glyphosate retention dynamics at organo-mineral interfaces: Formation of multiple hydrogen-bonds and inner-sphere configurations at pectin-goethite interfaces

Behrooz Azimzadeh, Carmen Enid Martínez

Published: 2022-07-23
Subjects: Agriculture, Analytical Chemistry, Biogeochemistry, Environmental Chemistry, Environmental Sciences, Organic Chemistry, Physical Chemistry, Soil Science

The retention of glyphosate is strongly governed by adsorption and desorption processes at environmental interfaces. In particular, glyphosate can react with organo-mineral associations (OMAs) in soils, sediments, and aquatic environments. Here, we use in-situ time-resolved attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy to provide a mechanistic understanding of [...]

Agricultural practices have created tens of millions of small artificial water bodies (“farm dams” or “agricultural ponds”) to provide water for domestic livestock worldwide. Among freshwater ecosystems, farm dams have some of the highest greenhouse gas (GHG) emissions per m2 due to fertilizer and manure run-off boosting methane production – an extremely potent GHG. However, management strategies [...]
