Farming Systems Trial

“Manure management in the United States must move from a disposal-based model to a circular resource framework that integrates nutrient recovery, emission mitigation, precision application, supportive policy, and site-specific decision-making.”

“A model that simulates the processes of NH formation, speciation, aqueous-gas partitioning, and mass transfer was developed and incorporated in a whole farm simulation model (the Integrated Farm System Model).”

“The Palouse region of Washington and Idaho, USA. (approximately 60,000 people in a rural setting) is entirely dependent on groundwater from two basalt aquifers for potable water.”

“This review summarizes current understanding of high-latitude dust sources and provides a prospectus for future research.”

“We present a state-of-the-art distributed Wireless Sensor Network-based autonomous measurement system with real-time remote data transmission that gathers data of snow depth, air temperature, air relative humidity, soil moisture, soil temperature, and solar radiation in physiographically representative locations.”

“The creation of the National Integrated Drought Information System (NIDIS) Portal within the United States provided an opportunity to take the first steps toward building the informational foundation for a GDIS.”

“Phosphorus availability and leaching losses in annual and perennial cropping systems in an upper US Midwest landscape.”

“Long-term soil C and N gains aren’t just “more inputs.” Residue quality + crop-sequence diversity matter: low C:N organic residues and more temporally diverse rotations increased soil C/N retention.”

“The High-Resolution Rapid Refresh (HRRR) is a convection-allowing implementation of the Advanced Research version of the Weather Research and Forecasting Model with hourly data assimilation that covers the conterminous United States and Alaska and runs in real time at the NOAA/National Centers for Environmental Prediction.”

“In 13 years of the Rodale Farming Systems Trial, cutting tillage lowered gross revenues about 10-13% in conventional and low-input organic systems but also trimmed costs 5-6%, leaving net returns essentially unchanged (though with more year-to-year economic risk). The manure-based organic system with continuous living cover was least affected by reduced tillage and out-earned the conventional system even without organic price premiums.”

“We derive the first multiyear, monthly resolution N 2 O emissions from three of the four major eastern boundary upwelling systems using highfrequency coastal atmospheric measurements and an inverse method.”

“Reducing tillage affected long-term maize yields but did not compromise grain quality.”
