Spain is one of the countries with the highest greenhouse gas (GHG) emissions within the EU-27. Consequently, mitigation strategies need to be reported and quantified to accomplish the goals and requirements of the Kyoto Protocol. In this study, a first estimation of the carbon (C) mitigation potential of tillage reduction in Mediterranean rainfed Spain is presented. Results from eight studies ...

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...

Hairy vetch (Vicia sativa L.) succeeded by corn (Zea mays L.)or grain sorghum (Sorghumbicolor L. Moench) were seeded insplit plots randomized within whole plots of no-tillage versus conventional tillage over four growing seasons (1980-83). The vetch-corn cropping system increased the density of Meloidogyne incognita 2.9 X more than the vetch-grain sorghum cropping system. I n contrast, the vetc...

abstract in order to assess the environmental impact of agricultural activity, the long-term sustainability should be considered. in order to achieve solutions to reduce energy consumption and carbon emissions in the production of rainfed sunflower, this assessment was conducted in the north east of iran. four production methods, i.e. conventional tillage (ct), tow reduced tillages (rt1and rt2)...

The effects of tillage methods and residual management on yield and yield components of rapeseed (Brassica napus L. CV. Hyola308) were evaluated after rice harvest. The experiment was carried out during 2004-2005 cropping season in a factorical arrangement of treatments at Rice Research Institute of Iran (RRII) in Rasht, in a Complete Randomized Block Design with three replications. Treatments ...

Appropriate tillage plays an important role in mitigating the emissions of greenhouse gases (GHG) in regions with higher crop yields, but the emission situations of some reduced tillage systems such as subsoiling, harrow tillage and rotary tillage are not comprehensively studied. The objective of this study was to evaluate the emission characteristics of GHG (CH4 and N2O) under four reduced til...

Crop production process utilizes input energy and produces some biomass energy as output.  During this process, greenhouse gases (GHGs) are also emitted which can make environmental risks. In this study, input and output energies, energy indices, and GHG emissions arising from inputs were estimated for wheat-cotton rotation under different tillage practices in Fars province. The study was condu...
