| ABSTRACT Soil tillage that maintains the productivity of sugarcane plantations, providing an area for the root development and without traffic on crop rows, has given rise to new technologies in rural areas. The purpose of this study was to evaluate the soil physical properties in two sugarcane plantations, one of which was prepared with deep tilling and the other with conventional tillage. The experiment was conducted in Lençóis Paulista, São Paulo State. Soil penetration resistance and relative density were analyzed. The cone index was lower in deep-tilled soil without traffic in all layers, than in deep-tilled soil with traffic and in conventional tillage. In both tillage treatments, the relative density values were acceptable in the 0.00-0.15 m soil... |

| The tillage and residue management during soil bed preparation need to be in appropriate manner for sustainable farming practice. The effects of tillage and residue management methods on corn cropping were studied on loamy soil in Bangrakum district, Phitsanulok Province, Thailand. The effects of five commonly used tillage methods: subsoiler tillage (ST), three methods of conventional tillage (CT1, CT2 and CT3), no-tillage (NT), as main factors and two corn residue management methods; burned (R1) and unburned (R2), as sub-factors were studied in a randomized strip plot configuration. Tillage treatment showed significant effect on physical and chemical soil properties, plant growth and development, grain yield, total aboveground biomass and most... |

| Rising fossil fuel prices are leading to an increasing awareness of energy efficiency in plant production. Tillage in particular can consume large amounts of fuel. For four tillage implements (reversible mouldboard plough, short disc harrow, universal-cultivator, subsoiler), this study quantifies the effect of different working depths on fuel consumption, wheel slip, field capacity and specific energy consumption. A four-wheel drive tractor (92 kW) was equipped with a data-acquisition system for engine speed, vehicle speed, wheel speed and fuel consumption. Fuel consumption was measured in the fuel system with an integrated high-precision flow-meter. The results show that the area-specific fuel consumption increased linearly with working depth for... |
