Sentences with phrase «conventional tillage»

Lafond and Derksen (1995) monitored rooting zone soil temperature from spring to fall for conventional tillage (CT) and zero - tillage (ZT).
Among these are shifting from conventional tillage to minimum - till and no - till, the more extensive use of cover crops, the return of all livestock and poultry manure to the land, expansion of irrigated area, a return to more mixed crop - livestock farming, and the forestation of marginal farmlands.
Some of these benefits led to reductions in the emission of the greenhouse gas (GHG) carbon dioxide (less fuel and machinery used than in conventional tillage systems).
However, N2O emissions from deep placement of N were obtained after other rainfall events, all indicating that deep placement reduced N2O emissions from zero till to levels as low as from N fertilizer incorporated in the surface layer in conventional tillage.
Studies should compare crops grown in a zero tillage system with a conventional tillage system, with nitrogen fertilizer banded on the cereals.
This review would include determining how these nitrous oxide emissions from zero tillage systems compared with those from conventional tillage, and identifing gaps in knowledge requiring further experiments and studies.
When spring thaw emissions were combined with growing season emissions, the conventional tillage system actually had higher total nitrous oxide emissions than the zero till system.We suggest that this type of experiment (full year emission measurements) be repeated with deep banding of N fertilizer, which would be expected to further reduce emissions from zero till systems.
2010 Research highlights Our meta - analysis based on data from 69 paired - experiments indicated that: ▶ Cultivation with conventional tillage (CT) and no - tillage (NT) resulted in comparable soil C loss comparing with adjacent natural soils.
According to Fernández, the best place for strip till is in fields with a lot of crop residue and conditions that tend to be cool and wet in the spring and where farmers prefer not to do conventional tillage.
Growing corn continuously under conventional tillage and with high inputs of water and fertilizer may seem outmoded, but this management system is «not uncommon,» as demand for corn grain and crop residues grow, Blanco says.

Not exact matches

Microbial community response to transition from conventional to conservation tillage in cotton fields.
The industry claims that this farming system requires less skills and knowledge than the conventional farming system because farmers do not have to select among a range of herbicide active ingredients, carefully time their herbicide application and apply other non-chemical control practices such as plowing, deep tillage or manual weeding.
In the paper, he reported that they (University of Alberta and Alberta Agriculture, Food and Rural Development) had compared the two tillage systems (zero till and conventional till) and had included spring thaw emissions as well as growing season emissions.
Microbial community response to transition from conventional to conservation tillage in cotton fields.
When the emissions from the two time periods were added up, the zero till had slightly lower total emissions than conventional till.However, the N fertilizer was surface applied in both tillage systems and incorporated in the conventional till system.
These studies did not compare deep banding with broadcasting fertilizer, or compare zero tillage with conventional tillage.Emissions of N2O were proportional to the amount of N fertilizer applied.
Unlike organic agriculture, conventional farming uses mechanized tillage, synthetic fertilizers and biocides — all practices that can damage the environment.
