The paper presents the results of comparative field studies tillage quality commercial and combined (for primary layer-by-layer tillage) plow bottoms in terms plowing parameters, particular, completeness crop residue incorporation density tilled soil layers. study are directed to a wider introduction technical means intoproduction that provide conditions for resource saving when performing with...

The analysis of soil cultivation technologies for sowing melon crops was carried out. design a combined tillage tool capable plowing, pre-sowing treatment and formation irrigation furrows in one pass substantiated. main is recommended to be done by front plow tools smooth plowing. Plow bodies two bottom plows should mounted along the symmetry axis implement according lister scheme, which allows...

Soil C change and CO2 emission due to different tillage systems need to be evaluated to encourage the adoption of conservation practices to sustain soil productivity and protect the environment. We hypothesize that soil C storage and CO2 emission respond to conservation tillage differently from conventional tillage because of their differential effects on soil properties. This study was conduct...

a one-way moldboard plow turns over soil in only one direction. problems created by this type of tillage in iran include compaction of boundary regions, decreased efficiency of irrigation and disruption of bed leveling, requiring the use of bed-leveling equipment every few years. to overcome these problems, the use of a two-way plow with two harrows which turns over the soil to both the left an...

The availability of renewable energy does not meet the demands of consumption. Hence, fossil fuels will continue to be an important energy source, and coal promises to cover the requirements for the coming decades. Because of its high energy content, deep lying bituminous coal and anthracite are important for energy generation. One trend in the future of coal mining is thin seam mining, because...

Snow and ice removal and clearing roadways after a winter storm account for major portion of roadway agencies located in snowy region’s maintenance budget. With the decreasing funds and increasing demand from the motoring public for mobility, roadway agencies are continuously looking for new innovative approaches for winter maintenance operations. One of the main focus of these approaches inclu...

An innovative task learning system called PLOW (Procedure Learning On the Web) lets end-users teach procedural tasks to automate their various web activities. Deep natural understanding and mixed-initiative interaction in PLOW makes the teaching process very natural and intuitive while producing efficient/workable procedures.

Abstract The process of smooth plowing with the turnover layers within its own furrow is characterized by high energy costs due to interaction plow body and in conditions blocked cutting. purpose research substantiate type second-rear frontal plow. proposed front for contains twin screw housings, first-row colliders, rear right- left-turning second-row colliders. Screw housings are equipped mir...
