Draft measurement of five tyne duck foot plough in clay soil

Draft and drawbar power equirement of moldboard plow in a clay loam soil

Simulation of the Impact of the Soil Friction on the Draft Resistance of the Plough Body

By using analytical correlations derived as a result of theoretical research, a computer algorithm has been worked out for simulating the functions of the plough body and the forces exerted by soil upon the operating parts, as well as its draft resistance. These correlations allow to determine the draft resistance of the plough depending on the parameters of its body, as well as to evaluate the...

Draft Force Inputs for Primary and Secondary Tillage Implements in a Clay Loam Soil

Tillage is the base operation in agriculture and its energy represents a considerable portion of the energy utilized in crop production. To measure the implement force requirements, are used dynamometers that are pull or three-point hitch types. In this research, an 82 kW research tractor equipped with an instrumentation system was used to determine the draft force inputs for four common tillag...

Quality evaluation of processed clay soil samples

INTRODUCTION This study assessed the microbial quality of clay samples sold on two of the major Ghanaian markets. METHODS The study was a cross-sectional assessing the evaluation of processed clay and effects it has on the nutrition of the consumers in the political capital town of Ghana. The items for the examination was processed clay soil samples. RESULTS Staphylococcus spp and fecal col...

Physicochemical Properties of Soil from Five Villages in Botswana with Respect to Soil Degradation

field study was conducted at five villages of Botswana namely, Tsabong, Tshane, Mathathane, Motlhabaneng and Tsetsejwe during the periods of June to August 1999 and June to August 2000. The objective of the study was to assess and compare the soil physicochemical properties of soils at the five villages and to study the effect of cultivation on some soil physical properties. Parameters measured...
