Soil micro-food webs play an essential role in maintaining or improving the stability of agricultural soils, and they can be influenced by tillage. However, little is known with respect to soil microbial faunal communities their relationships shaped long-term tillage practices. The goal this study was investigate impact 38 years no-tillage (NT), subsoil (ST), moldboard plow (MP), rotary ridge (...

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...

one of the main strategy for controlling salt-affected soils is to implement proper tillage method. a field experiments was conducted to determine the effect of different tillage methods on salt distribution and wheat yield in saline-sodic soil. the experiment was laid out according to randomized complete block design with three replications. treatments were studied in the experiment including ...

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...

Clear Lake is on Iowa's list of impaired water bodies because of high P concentration. This study assessed soil-test phosphorus (STP), management practices, and P loads from its agricultural watershed. Management practice histories and STP for eight basins were surveyed in 1999. Soil samples (15-cm depth) were analyzed for STP with agronomic [Bray P1 (BP), Olsen (OP), Mehlich 3 (M3P) and enviro...

the objective of this study was to determine the quicker response of subsoil or surface soil to minimum tillage (mt) and conventional tillage (ct) and biofertilizers (bacillus coagulans, b), phosphorus fertilization (p) and integrated p and b (pb) under the wheat (triticum aestivum l vr. sardari) growing season. the experimental design was split plot laid out in randomized complete block design...
