Field experiments were conducted to study weed population shifts in long-term conservation tillage systems. The objectives of this study were to determine weed community abundance, diversity and composition on conventional tillage (CT), minimum tillage (MT), no-tillage with paraplow (ZT) and no-tillage (NT) systems, and to identify species that are associated with specific tillage systems. The ...

In Central Aragón (NE Spain), where strong and dry winds are frequent all year round, fallow lands are susceptible to wind erosion due to insufficient crop residues on the surface and loose, finely divided soils by multiple tillage operations. Effects of conventional tillage (CT — mouldboard ploughing followed by a compacting roller) and reduced tillage (RT — chisel ploughing) on soil surface p...

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...

Ridge and furrow fields are land-use-related surface structures that widespread in Europe represent a geomorphological key signature of the Anthropocene. Previous research has identified various reasons for intentional unintentional formation these structures, such as use mouldboard plough, soil improvement drainage. We used GIS-based quantitative erosion modelling according to Universal Soil L...

By using analytical correlations derived as a result of theoretical research, a computer algorithm has been worked out for simulating the functions of the plough body and the forces exerted by soil upon the operating parts, as well as its draft resistance. These correlations allow to determine the draft resistance of the plough depending on the parameters of its body, as well as to evaluate the...

Two jets from the Orion (M42) 'proplyds' – kinematics, morphologies and origins. ABSTRACT A spatially unresolved velocity feature, with an approaching radial velocity of ≈ 100 km s −1 with respect to the systemic radial velocity, in a position–velocity array of [O iii] 5007Å line profiles is identified as the kinematical counterpart of a jet from the proplyd LV 5 (158–323) in the core of the Or...

In arable cropping systems, reduced or conservation tillage practices are linked with improved soil quality, C retention and higher microbial biomass, but most long-term studies rarely focus on depths greater than 15 cm nor allow comparison of microbial community responses to agricultural practices. We investigated microbial community structure in a long-term field trial (12-years, Lincoln, New...

Soy is a multipurpose oilseed crop. It highly nutritious and improves soil fertility. Rainfed agriculture needs to improve crop cultivation technologies focuses on various methods of that contribute the formation an optimal agrophysical structure contributes consistently high soybean yield. Therefore, it expedient relevant study influence tillage density hardness in two phases development (begi...
