Flaxleaf fleabane is a difficult-to-control weed in dryland minimum tillage farming systems in the northeast grains region of Australia. Experiments were conducted between 2003 and 2005 to identify effective control strategies on flaxleaf fleabane in wheat and sorghum. A preplant application of chlorsulfuron at 15 g ai/ha in wheat controlled flaxleaf fleabane $ 90%. The efficacy of early postem...

Since the 70´s, Pampa Arenosa Subregion has experienced a rise in its water regime, allowing greater area for dryland farming. Given farming intensification, assessing lands on basis of rainfall variations is fundamental strategic tool planning. The objective this work to highlight importance different climate scenarios when determining Productivity Index Subregion, Argentina. study was located...

Straw and animal manure are major organic waste materials from agricultural ecosystems. Different kinds of combined with straw (AM-S) may have varying effects on the decomposition, nutrient release, structural changes maize straw. Using Humic Cambisols soil as experimental area, decomposition characteristics under co-application were studied following nylon net bag landfill method. The experime...

An understanding of the dynamics of soil organic carbon (SOC) as affected by farming practices is imperative for maintaining soil productivity and mitigating global warming. The objectives of this study were to investigate the effects of long-term fertilization on SOC and SOC fractions for the whole soil profile (0-100 cm) in northwest China. The study was initiated in 1979 in Gansu, China and ...
