Author: Gabriel de Oliveira, Nathaniel A.Brunsell, Timothy E.Crews, Lee R.DeHaan, GiuliaVico
Publication: Plant Science

Abstract: Perennial crops have been proposed as a more sustainable alternative to annual crops, because they have extended growing seasons, continuous ground cover, reduced nutrient leakage, and sequester more carbon…

Publication: Agronomy

Abstract: It has been hypothesized that the genetic control of forage traits, especially biomass, for grass plants growing as spaced-plants versus swards is different. Likewise, the genetic control of compatibility…

Publication: Renewable Agriculture and Food Systems

Abstract: Arbuscular mycorrhizal fungi (AMF) can increase plant nutrient uptake and chemical defense production, both of which can improve plants’ ability to resist insect herbivory. Cover crops—non-commercial species planted in…

Publication: Agriculture, Ecosystems, and Environment

Abstract: Global expansion of high-input annual grain crops and associated nitrogen (N) fertilizer use can have negative consequences for the environment and human health. Nitrate nitrogen (NO3-N) leaching from fertilized…

Publication: Global Sustainability

Non-technical summary: Modern agriculture is associated with numerous environmental predicaments, such as land degradation, water pollution, and greenhouse gas emission. Socio-economically, it is characterized by a treadmill of technological change, increased…
