introduction main part of energy consumption in agricultural mechanization is tillage operations therefore optimization of energy consumption in tillage operation is very important. a management method for system to optimize in agriculture is simple additive weighting (saw) methodology that this method can operate according to criteria of the systems. this method states that, which system has b...

Only 34% of all German farms apply reduced tillage (RT), while approximately 1% of the arable land is under no-tillage (NT). Statistics for organic farming are not available, but the percentages are probably even lower. The development of German organic RT and NT has been strongly driven by pioneer farmers for 40 years, and supported by field trials since the 1990s. The main motive for conversi...

this study carried out to evaluate the effect of different tillage systems on rapeseed yield (hayola 401) planted in corn residues. this experiment was done in moghan region with clay soils during 2009-2012. different seedbed preparation methods include mt: moldboard + disk tillage (conventional tillage was included), sct: stem crusher + chisel + disk tandem harrow, stt: stem crusher + double-d...

The cereal leafminer, Syringopais temperatella Led. (Lep., Scythrididae) is considered one of the most serious insect pests that infests wheat in field, and causes economic damages to crop Jordan. However, little attention has been paid susceptibility common cultivars no combined use tillage regime insecticides against S. temperatella. Concomitan tly, this study aimed at investigating commonly ...

Abstract Chisel plows with a chisel as working body, loosen the soil without mixing layers. The analysis of conducted research concludes that most widespread is cylindrical surface body - constant radius curvature. It theoretically established at curvature bit up to 0.1 m, on will move chaotically, while does not affect percentage wrapped plant debris. As increases, force inertia decreases, the...

A field study was conducted to assess the effects of soil tillage practices and straw management on soil CO2, and yield-scaled CO2 emissions in a rain-fed summer corn field on the Loess Plateau. Tillage treatments consisted of sub-soiling tillage (CP), no tillage (NT) and moldboard plow tillage (CT). Wheat straw was removed from half of the CP, NT and CT plots after harvest, allowing us to test...

During the last decade in Mexico, profitability of basic grain crops has decreased considerably due to low productivity caused by unfavorable soil and climatic conditions, which are aggravated climate change. In addition, variability international economic environment rise fertilizer fuel prices factors that seriously affect production these food products. this context, it is important generate...

Recent studies of SOC storage and turnover have employed 13C natural abundance ( 13C) as an in situ Soil organic carbon (SOC) is sensitive to management of tillage, marker of relic and recent SOC pools. Mass concentraresidue (stover) harvest, and N fertilization in corn (Zea mays L.), tions of SOC and the 13C signature are sufficient to but little is known about associated root biomass includin...

The ability of tillage implements to maintain surface residue coverage is largely dependent on the implement’s main active component. Two categories of tillage implements were compared to determine their ability to maintain grain sorghum (non–fragile) surface residue coverage when operating at two different tillage depths for fall and spring tillage. Chisel–type implements were found to bury su...

Traditional tillage represents a serious threat to the stability of soil ecosystems. Understanding response mechanisms microbial community assembly different practices is major topic ecological research. Here, we investigated bacterial structures and in bulk rhizosphere soils soybeans grown under traditional (moldboard plow, MP) two conservation practices, namely, no-tillage (NT) ridge (RT), us...
