Particle-size distribution (PSD) is a key parameter affecting soil dynamic attributes and cutting forces of tillage tools in the discrete element model accordance with our preliminary simulations. To accurately determine PSD, significance mechanism for effect PSD under different nominal radii were investigated using method (DEM) validated laboratory soil-bin results. Soil disturbance characteri...

Citrus companies have sought and developed alternative systems of tillage or implanting orchards so as not to significantly alter the physical chemical attributes soil and, consequently, root development plants. Therefore, aim this study was identify that most influence volume orange crop in different systems. The experiment carried out region Avaré, state São Paulo, Brazil, Utissol Oxisol. For...

this study describes the design, construction and calibration of an adjustable three-point hitch dynamometer. the dynamometer frame design was based on an inverted u-shaped frame that was mounted between the tractor links and implement. the dynamometer frame design allows for use in both category i and ii three-point hitch systems because of its flexibility in a lower point hitch spread and mas...

The applied methods of fertilizing cotton in Uzbekistan have a number significant disadvantages. They do not provide available nutrients to the plant's root system. With distribution fertilizers zone development layers required ratio, coefficient their use and yield increases. (Purpose study) To substantiate design parameters subsoiler's pipeline for three-tier fertilization. (Materials methods...

At present, the role of agricultural practices on dynamic GHGs is being investigated worldwide. In this study, effects soil tillage (conventional vs. conservation techniques) and fertilization sources (inorganic organic) CO2 emissions in durum wheat (Triticum Desf.)–potato (Solanum tuberosum L.) rotation Mediterranean area were evaluated. This study aimed to understand changes carbon content un...
