Conventional and reduced tillage in Hungary — A review
Soil and Tillage Research, 1989Abstract Tillage systems commonly used in Hungary are in no way similar to the number of new soil-preserving shallow-tillage or direct-drilling systems now commonly used in other countries. The applicability of such new methods in Hungary is currently being tested.

A study was conducted on a tropical Alfisols on the Teaching and Research Farms of University of Ibadan in order to determine the effect of three tillage (no-tillage, minimum and conventional tillage) systems on infiltration of water in the soil. The experiment was a split-plot design with three replications.

Response of no‐tillage and conventional‐tillage cotton to starter fertilization on loess soils
Journal of Plant Nutrition, 1997Abstract Starter fertilizers have been utilized to improve cotton (Gossypium hirsutum L.) yields, but yield increases have differed with soil type, application method, application rates, and tillage. Starter fertilizer tests were conducted from 1991 through 1993 on a Gigger silt loam (Typic Fragiudalf) in Louisiana and on a Loring silt loam soil (Typic

Effects of Conventional Tillage and Conservation Tillage on Soil Organic Carbon
Advanced Materials Research, 2013For the last decades, because of increasing attention to global change, the carbon cycle in the terrestrial ecosystem has become a hotspot problem for every country. It has 1.6 Pg/a C to release into atmosphere because of the irrational land-use, quickening the step of global warming trend. But agricultural soil has the double-sword effects.

SOIL MICROARTHROPODS IN LONG-TERM NO-TILLAGE AND CONVENTIONAL TILLAGE CORN PRODUCTION
Canadian Journal of Soil Science, 1990Cultivation is known to reduce the number and diversity of microarthropod (Acarina and Collembola) populations from levels observed under natural forest or grassland vegetation. Under no-tillage crop production, the soil remains relatively undisturbed and plant litter decomposes at the soil surface, much like in natural soil ecosystems.

Allelochemicals in soil from no-tillage versus conventional-tillage wheat (Triticum aestivum) fields
Journal of Chemical Ecology, 1990Putative allelochemicals found in the soil of no-tillage and conventional-tillage wheat plots near Stillwater, Oklahoma, were obtained by a mild alkaline aqueous extraction procedure, bioassayed to determine their biological activity, purified, and analyzed with a capillary gas chromatography-mass spectrometry-data analysis system. The most significant

Nitrification and Denitrification in Conventional and No‐Tillage Soils
Soil Science Society of America Journal, 1985Abstract Nitrification and denitrification were studied over the course of a year in conventional and no‐tillage agroecosystems. Soils were sampled monthly at three depths (0–5 cm, 5–13 cm, 13–21 cm). Nitrification was quantified by measuring nitrite (NO − 2

Population Dynamics of Weeds in No-Tillage and Conventional Crop Systems
Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes, 2005Population dynamics of weeds in successive maize and bean crops were evaluated in two soil management systems (conventional and no-tillage), for two maize applications (grain and silage), and in four consecutive growing seasons. Every year, conventional tillage consisted in plowing and harrowing before sowing.

Effect of no‐tillage vs. conventional tillage on soil organic matter and nitrogen contents
Communications in Soil Science and Plant Analysis, 1987Abstract Four treatments (no‐tillage plus subsoiling, no‐tillage, conventional tillage plus subsoiling, and conventional tillage) were continuously in place for 6 yr and a second set of no‐tillage plus subsoiling and conventional plus subsoiling treatments were continuously in place for 3 yr to study the long‐term effects of conventional and no‐tillage

AbstractNo‐tillage (NT) and other conservation management practices designed to enhance plant residue accumulation can affect the herbicides fate in soil. This study was designed to evaluate adsorption, desorption, and degradation of chlorimuron {ethyl 2‐[[[[(4‐chloro‐6‐methoxy‐2‐pyrimidinyl)amino]carbonyl]amino] sulfonyl]benzoic acid} in soils ...
