The paper studies the direction turnover layers along slope and placement of working bodies on a plow for plowing fields. diagrams layout are given. It is proved that intermittent grooves ridges, according to agro technical requirements, it necessary rotate downhill. was found when installing cut-out spherical disk behind front cases, groove formed above under it. subsequent layer wrapped in an...

The pick is the working part of coal plow, cutting performance very important for efficient production mine. In order to analyze dynamic characteristics plow during process, a test platform was built. force and vibration head were obtained through test, relationship between speed depth analyzed. study influence different alloy shapes on pick, two kinds designed: with chip bit conical bit. finit...

ated with soil type, vadose zone flow and transport processes are also affected by such external factors as tillage Vadose zone flow and transport processes are known to be strongly practices. For example, Petersen et al. (1999, 2001) affected by both soil structure and soil texture. We conducted a field experiment to explore the impact of heterogeneity in soil structure showed that surface til...

performance optimization of chisel tine was proposed by using a chisel plow with adjustable rake angle. effective treatments consisted of soil moisture at 0.5, 0.7 and 0.9 of plastic limit (pl), three rake angle of 30, 40 and 50 degree and speeds of to 3, 5 and 7 km h-1. the measured parameters included draft, soil disturbance area, soil upheaving area, clod mean weight diameter (mwd), specific...

In cold weather cities, snowstorms can have a significant disruptive effect on both mobility and safety, and consequently the faster that streets can be cleared the better. Yet in most cities, plans for snowplowing are developed using simple allocation schemes that while easy to implement can also be quite inefficient. In this paper we consider the problem of optimizing the routes of a fleet of...

The purpose of the study was to substantiate technology and parameters “paraplau” type soil dredger for a two-tier plow. basic principles methods classical mechanics, mathematical analysis statistics were used in this study. Sub-tillage loosening most compacted layers fields from under cotton must be carried out strip way along line middle irrigation furrows between rows. It is established that...

the purpose of this research was to study and predict fuel consumption rate of tractor due to different aspect ratios of chisel plow blade and to determine a general relationship equation between aspect ratio ( ) and fuel consumption rate.  an itm-399 (81 kw) tractor and a mounted-type chisel plow with 9 shanks were used. the 5 and 10 cm width chisel blades were used. the experiments were condu...

Movement and persistence of 1,2-dibrotno-3-chloropropane (DBCP) in a Coastal Plain soil containing a sandy plow-pan were enhanced in each of 2 years by subsoiling, increased depth of application, and increased rate of application. DBCP was extracted from the soil with hexane and analyzed by gas chromatography. Subsoiling at a 35-cm depth gave the greatest increase in lateral movement and downwa...

 Study Design: Split-plot.
 Place Duration Study: Maize Research Centre, ARI, Rajendranagar between November 2021 April 2022.
 Methodology: A field experiment was conducted at Rajendranagar, Hyderabad, Ranga Reddy (District) during 2021...

The possible impact of Rotylenchulus reniformis below plow depth was evaluated by measuring the vertical distribution of R. reniformis and soil texture in 20 symptomatic fields on 17 farms across six states. The mean nematode population density per field, 0 to 122 cm deep, ranged from 0.4 to 63 nematodes/g soil, and in 15 fields more than half of the R. reniformis present were below 30.5 cm, wh...
