Nowadays, using the technology and computers for decision making in a particular field is one of the subjects which in the level of making decisions and industrial managements has been very much noticed. Especially, the decision which on the base of current specific condition is required, such as making decisions in the selection of suitable primary tillage equipment for given conditions of a f...

One of the major goals of the Sustainable Agriculture Farming initiatives at UC Davis is to provide information about the feasibility of adopting conservation tillage and cover cropping at the farm level. The project includes two tillage schemes: standard tillage (ST) and conservation tillage (CT), and three farming methods: conventional, organic, and winter legume cover crop. All three product...

Conservation tillage and even no tillage as a practice is not new. However, there appears to exist evidence that in some cases no-tillage is successfully incorporated into a new concept of truly sustainable agriculture, gaining popularity as “conservation agriculture” all over the world. Conservation Agriculture is, besides no-tillage and direct planting, based on very old concepts such as gree...

Soil carbon (C) losses and soil translocation from tillage operations have been identified as causes of soil degradation and soil erosion. The objective of this work was to quantify the variability in tillage-induced carbon dioxide (CO2) loss by moldboard (MP) and chisel (CP) plowing across an eroded landscape and relate the C loss to soil properties. The study site was a 4 ha wheat (Triticum a...

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...

of Research Findings Alternative tillage and cropping systems are sought for reducing dust emissions and improving air quality in the Pacific Northwest dryland cropping region. The purpose of this study was to modifiy the conventional rodweeder that would facilitate the armouring of the soil surface with straw and large aggregates otherwise buried below the soil surface. Several modifications w...
