in conventional tillage systems, uniform depth tillage is applied over the entire field; however, the depth of hardpan layer varies greatly within the field. site-specific tillage, which modifies physical properties of soil only where the tillage is needed for crop growth, could achieve significant savings in fuel consumption and drawbar power requirements. site-specific tillage can be implemen...

The cultivation of agricultural soils has until recently predominantly been achieved by inverting the soil using tools such as the plough. Soil tillage is one of the basic and important components of agricultural production technology. Various forms of tillage are practised throughout the world, ranging from the use of simple stick or jab to the sophisticated para-plough. The practices develope...

The alternative soil tillage technology plays an important role in the development of a sustainable agriculture. The use of traditional technology gives the farmers a positive expected income. With the use of an alternative soil tillage technology, the expected income considerably rises together with the income risk. Combinations of income and risk revealed that the use of traditional technolog...

Background: Soils contain the greatest terrestrial carbon (C) pool on the planet. Since approximately 12 % of soil C is held in cultivated soils, management of these agricultural areas has a huge potential to affect global carbon cycling; acting sometimes as a sink but also as a source. Tillage is one of the most important agricultural practices for soil management and has been traditionally un...

Tillage information is crucial for environmental modeling as it directly affects evapotranspiration, infiltration, runoff, carbon sequestration, and soil losses due to wind and water erosion from agricultural fields. However, collecting this information can be time consuming and costly. Remote sensing approaches are promising for rapid collection of tillage information on individual fields over...

Background: The loss of carbon (C) from agricultural soils has been, in part, attributed to tillage, a common prac‐ tice providing a number of benefits to farmers. The promotion of less intensive tillage practices and no tillage (NT) (the absence of mechanical soil disturbance) aims to mitigate negative impacts on soil quality and to preserve soil organic carbon (SOC). Several reviews and meta‐...

The adoption of conservation tillage technology since the 1970s has been one of the most remarkable changes in the production of crops on the Canadian Prairies. The decision whether to adopt conservation tillage technology or not requires the producer to go through a thorough decision making process. In Canada there has been little economic research on the question of what farm, regional, and e...

For centuries tillage has been used to prepare suitable seedbed to grow crops, and to control weeds and incorporate fertilizers, pesticides, manures and other amendments. In early years conversion of native ecosystems by tillage helped to unlock nutrients stored in soil organic matter, and thus `mine' naturally fertile soils to grow crops with minimum inputs for the growing population. However,...
