Soybean weed community composition and richness between 1995 and 2003 in the Rolling Pampas (Argentina)

Woody Plant Invasions in Pampa Grasslands: A Biogeographical and Community Assembly Perspective

“…At present, trees are virtually everywhere, and invasive species threaten to become problematic weeds too. By the end of the twentieth century, all fi elds had been converted into zero-tillage cropping, which involves growing glyphosate-resistant soybean transgenic cultivars (De la Fuente et al 2006 ) . This shift to no-till agriculture increased the likelihood of tree invasion, which was previously prevented by annual disturbance from tillage practices.…”

Ökológiai és agrotechnikai tényezők hatása a szántóföldi gyomtársulások faj- és jellegösszetételére = Effects of environmental and management factors on species and trait composition in arable weed communities

“…Egyes fajok a magas termékenységi mutatókkal és a kukorica előveteménnyel, míg mások a búza előveteménnyel asszociálódtak. Fuente et al (2006) szerint a talajművelési rendszer és a szójafajták voltak azok a fő agronó-miai tényezők, amelyek befolyásolták a gyomfajok előfordulását.…”

Determinants of agricultural land values in Argentina

“…The negative impacts of the "modelo sojero" are now widely documented (Carreño et al, 2012;de la Fuente et al, 2006;Gavier-Pizarro et al, 2012;Leguizamón, 2013). They include land concentration far beyond what is considered a desired structure, increase in short-term contracts for land, a net loss of employment due to lower needs and the requirement of higher skills that many rural workers do not have.…”

“…Contract farming in Argentina thus remains a highly contested model. Attention has recently been paid in the literature to the value of the biophysical attributes of land, suggesting that land values may vary with potential environmental contamination (Boisvert et al, 1997), soil exhaustion and degradation (Sills and Caviglia-Harris, 2009), and the cropping history of the plot (de la Fuente et al, 2006). Another strand of literature emphasizes the implications of land tenure on fertilization, adoption of conservation practices, and longterm land improvements (Abdulai et al, 2011;Myyrä et al, 2007;Soule et al, 2000).…”
