Methods In 2013, ISU FARM conducted two trials in Pottawattamie County that investigated the effect of various tillage systems on soybean grain yield. In Trial 1, a fall vertical tillage system and a fall disking were compared with a no-till system. In Trial 2, a fall vertical tillage system was compared with no-till. Vertical tillage systems are marketed as systems that lightly till the soil w...

No-tillage cultivation offers significant advantages over con­ ventional tillage in terms of water, energy, and particularly soil conservation (Francis et al., 1987). However, continuous no-tillage farming on sandy Ultisols may lead to high bulk density that has a pronounced effect on soil strength due to traffic compaction and lack of plowing (NeSmith et al., 1987). This increase in soil stren...

Microbial diversity can be used to assess the impact of agricultural practices on the long-term sustainability of cropping systems. The aim of this study was to investigate changes in soil bacterial diversity as a result of the impact of different soil tillage and crop rotation systems in an oxisol of southern Brazil. Bacterial diversity was examined in the 010 cm layer in two field experiments...

An experiment with five different tillage systems and their influence on fuel consumption, labour requirement and yield of tested crops was carried out on Albic Luvisol in northwest Slavonia in the period of 1996.-2000. The compared tillage systems were: 1. conventional tillage system (CT), 2. reduced tillage system (RT), 3. conservation tillage system I (CP), 4. conservation tillage system II ...

This study addresses the tillage effect on the distribution of bacterial biomass and their community structure in a subtropical purple rice soil ecosystem. Similar distribution patterns of soil bacterial biomass within water-stable aggregates (WSA) were observed under different tillage managements. Although the distribution pattern of soil microbial biomass was not changed by tillage practice, ...

Your tillage system is important to the long-term sustainability of the farm enterprise. Matching a crop tillage system that is suited to your farm resources can provide both economic and environmental benefits. It is important to evaluate your land and determine what options would be appropriate. Several questions have arisen regarding new approaches or options in tillage systems compared to a...

High residue conservation tillage systems for cotton (Gossypium hirsutum L.) production have been proposed as having the potential to be both economically and environmentally sustainable, and research regarding till­ age systems has indicated that several advantages may exist for conservation tillage systems compared to con­ ventional tillage systems. However, adoption of new farming systems on...

Management systems influence soil quality over time. A randomized block design in 2 (tillage system) 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002–2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn–soybean, and corn–soybean–wheat–Cowpea systems. Ten soil cores were collected at 0–7.5, ...
