Changes in pore size distribution and aggregate stability of two soils under long term tillage systems
tillage systems bulk density pore size distribution aggregate stability
2008/11/26
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...
Changes in soil organic matter, bulk density and tensile strength of aggregatesafter percolation in soils after conservation and conventional tillage
percolation process carbon distribution aggregates strength
2008/11/26
The type of tillage in arable soils affects porosity of the soil and in consequence the hydraulic conductivity. The accessibility and mobility of organic carbon in arable soils can differ depending on...
Effects of tillage methods and depth on fuel consumption and profitability of late season okra productions
Abelmuscus esculentus fuel consumption okra profitability tillage method and depth
2008/11/26
The disc plough and disc harrow were used singly and in combination to produce seedbeds of depths 10, 15, 20, and 25 cm for late season okra (Abelmuscus esculentus) production. During the seedbed prep...

Soil mechanics has of late, taken on a new significance as a field worthy of expended research and application. The basic problem encountered in this field is the determi- nation of certain basic par...
Effect of different tillage systems and straw management on some physical properties of soil and on the yield of winter rye in monoculture
conventional tillage reduced tillage straw management soil winter rye

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...
Effect of tillage tool geometry on soil structural stiffness
tool geometry soil stiffness and behaviour
2008/11/19
The concept of structural stiffness signifies the level of resistance a body of agricultural soil develops so as to withstand any form of further deformation from subsequent external loading.In order ...
Effects of grass cover and tillage on temperature of soil in sloping vineyard**
soil temperature sloping vineyard tillage grass cover
2008/11/19
The effect of two management practices: grass cover (G) and traditional tillage (T) on the annual temperature variations of silt-loamy soil in inter-rows of sloping vineyard (Piedmont, Italy) was stud...
Maize response to different straw management and tillage systems under cereal crop rotation
straw management tillage systems maize yield cereal rotation
2008/11/14
The aim of this study was to determine the effect of various straw management and tillage systems on the emergence, grain yield and cob characteristics of maize (Zea mays L.) under different cereal ro...
Soil physical properties under winter wheat grown with different tillage systems at selected locations
soil water content soil bulk density soil stability in water readily-dispersible clay (RDC)
2008/11/11
The aim of this research was to determine in 2006 and 2007 the effects of different tillage systems on the soil physical properties: bulk density, water content and stability. Analyses of physical pro...
Tillage system effects on stability and sorptivity of soil aggregates
tillage soil aggregates stability sorptivity
2008/11/11
Stability and sorptivity of soil aggregates play
an important role in numerous soil processes and functions. They
are largely influenced by tillage methods. We have compared the
effects of long-ter...
