Sentences with phrase «deep tillage»

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.

Not exact matches

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.
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.
There is an extensive literature on the improvement in N fertilizer use efficiency achieved by deep banding in zero tillage systems, but no studies on N2O emissions.
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.
Thus in the zero tillage system the N was not deep banded.
