Noninversion tillage with tine- or disc-based cultivations prior to crop establishment is the most common way of reducing tillage for arable cropping systems with small grain cereals, oilseed rape, a...
The main objective of our study was to compare the contents and quality of humic substances in selected soil types under different tillage regimes (deep, reduced, minimum). Non destructive spectroscop...
Eight different soil tillage systems (TS) for winter wheat after soybean crop production were compared at the chernozem soil type in Croatian Baranya region in a 4-year period (2001/2002, 2002/2003, 2...

Reduced tillage systems are gaining popularity but weed control is often a limiting factor in the adoption of such systems. Cover crops have become a viable option for sustainable agriculture because ...
The effect of different tillage systems under organic management on soil quality indicators.
The experiment was conducted at the Research and Didactic Station of Poznań University of Natural Sciences (52o29' N; 16o49' E). The aim of the research was to evaluate the effect of tillage systems:...
The field experiment was conducted over 2002-2004 on the Experimental Farm at Zawady, on the soil made of light loamy sand to heavy loamy sand, representing a very good rye complex soil. The factors ...
Cassava is the most widely cultivated root crops among traditional farmers in the Midwestern Nigeria. Majority of the traditional farmers employ the zero tillage system. It is unclear if zero...
The experiment was conducted during the 2001-2003 cropping period to evaluate the effects of 3 tillage systems, conventional tillage (CT), and minimum tillage with rototiller (MTR) and disc (MTD), on...
Yield, N uptake, weeds and diseases of spring barley were examined under five mulching practices (white mustard, phacelia, oat-pea mixture, straw mulch, and no mulch), three tillage systems (conventio...
Cotton (Gosspium hirsutum L.) growth and yield following a white lupin (Lupinus albus L.) grain crop may be influenced by tillage system and rate of N fertilizer application. Field studies were conduc...
Cotton (Gossypium hirsutum L.) growers have adopted no-tillage systems with a cover crop in the Tennessee Valley under non-irrigated conditions, but a comparison of plant and soil parameters across ir...
Tillage-induced changes in pore-size distribution and aggregate stability of two soils were investigated for 7 con- secutive years from 1994 to 2000. The three tillage treatments were used: convention...
Field experiments were conducted on Orthic Luvisol derived from loamy sand in 1999-2002. The tillage systems applied were: conventional tillage (CT) including preplough (10 cm) + harrowing, mouldboard...
