Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The traditional tillage implement, the Maresha plow, and the tillage systems that require repeated and cross plowing have caused poor rainfall partitioning, land degradation and hence low water productivity in Ethiopia. Conservation tillag...

Fatty acid methyl esters (FAMEs) were used to `®ngerprint' soil microbial communities that evolved during 25 years of wheat-fallow cropping following native mixed prairie sod at Sidney, Nebraska, USA. Total ester-linked FAMEs (EL-FAMEs) and phospholipid-linked FAMEs (PL-FAMEs) were compared for their ability to discriminate between plots remaining in sod and those cropped to wheat or left fallo...

The primary goal of Serious Games is not only for fun but also lesson. In learning the first stage soil tillage which using mouldboard plow, a proper understanding needed so that process will follow needs plant growth. use serious games as study instrument under concept digital game-based (DGBL). problem players when playing less motivated to play because game system and scenario are challengin...

The paper proposes a new method for multistage plowing that implies loosening bottom soil and subsoil horizon simultaneously, followed by overturning the without cutting, which improves quality of cultivation, softens plow sole reduces energy costs. Experimental studies confirmed theoretical relationship determining resistance, both certain working bodies section, whole plow. proposed provides ...

The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

In cold climates, snowmelt runoff often exceeds rainfall runoff during the year. Conservation tillage practices may be effective in reducing runoff during the cropping season but not during the snowmelt period. A plot study was conducted on a cropped hillslope to assess how tillage practices affect snowmelt runoff and the associated losses of sediment, phosphorus (P), and chemical oxygen demand...

This work aims to substantiate the effectiveness of use an active working body on a front plow. The necessity using bodies is justified, and plow with passive proposed. efficiency installing analyzed. forces acting combined frontal are considered. analysis influence stability movement traction resistance carried out. results experimental studies presented. increases degree soil crumbling by 8,5...
