Tractor fuel requirements of two tillage systems and zero-tillage
New Zealand Journal of Experimental Agriculture, 1977Abstract The relative amounts of fuel used in 3 seedbed preparation and crop establishment systems were measured over a spring-summer-autumn period on 2 trial sites. The 3 tillage systems studied were: (i) Traditional cultivation based on mouldboard ploughing, rolling, disc and tine harrowing, and “levelling”, (ii) Rotary cultivating, rolling, and ...

Nitrogen Transformations under Zero and Shallow Tillage
Soil Science Society of America Journal, 1984Abstract A field study was conducted with the objective of determining if differences occur in soil N transformations between zero and conventional tillage systems. Tillage comparisons of 2, 4, 12, and 16 yr duration were studied at four locations on Chernozemic soils in Western Canada.

Dry Bean Production in Zero and Conventional Tillage
Agronomy Journal, 2007Adoption of zero tillage production practices for dry bean (Phaseolus vulgaris L.) has lagged behind that of many other crops. A field experiment was conducted at two locations on the Canadian prairies to determine the response of dry bean planted into various crop stubbles in conventional and zero tillage.

Evaluation of Different Herbicides in Zero Tillage Maize
Madras Agricultural Journal, 2012A field experiment was conducted at Agricultural Research Station, Kampasagar, Andhra Pradesh during rabi 2008-09 to evaluate different herbicides in zero tillage maize after kharif rice. The experiment was laid out in a randomized block design with nine treatments (atrazine as pre emergence @ 1.25 kg a.i.ha -1 , atrazine as post emergence @ 1kg a.i.ha

Applied Soil Ecology, 2010
Abstract Soil microorganisms mediate many important biological processes for sustainable agriculture. The effect of a polymer-coated controlled-release urea (CRU, ESN®) on soil microbial communities was studied at six sites across western Canada from 2004 to 2006. Fertilizer treatments were CRU, urea and an unfertilized control.

Zero Tillage in Switzerland: The Bernese Incentive Program
2003Farmland is increasingly being stressed with high axle loads and very intense soil tillage techniques. The structure of the soil is thereby becoming more and more unstable — causing lots of soil degradation problems — whereas, above all, its load capacity has to be markedly in-creased.

The effects of tillage and zero-tillage systems on soil aggregates in a silt loam
Journal of Agricultural Engineering Research, 1977Abstract Three seedbed preparation systems were compared over the 1973–1974 spring-summer season on a pseudogleyed “Tokomaru” silt loam, on two adjacent experimental sites. Experiment 1 was tilled and left fallow over the winter of 1973, while experiment 2 was left in pasture over the winter.

Decomposition of crop residues under conventional and zero tillage
Canadian Journal of Soil Science, 2004Field experiments were conducted to determine decomposition patterns of red clover (Trifolium pratense), field pea (Pisum sativum), canola (Brassica rapa) and wheat (Triticum aestivum) residues under zero and conventional tillage. Crop residue amounts produced in 2 trial years ranged from 1.6 t ha-1 for monoculture wheat to 6.05 t ha-1 for peas, and ...

Chemical weed control options for zero-tillage spring barley
Canadian Journal of Plant Science, 1996The need for yearly applications of non-selective and postemergence herbicides was evaluated in zero-tillage barley cropping systems in eastern Québec. The effects of six glyphosate treatments, fall-applied, at several rates and frequencies, and four postemergence herbicide treatments, on weed populations and crop yields, were measured over 2 yr in a ...
