Winter barley performance under different cropping and tillage systems in semiarid Aragon (NE Spain)

Soil management effects on aggregate dynamics in semiarid Aragon (NE Spain).

During decades, in semiarid rainfed Aragon, intensive soil tillage and low crop residue input have led to the loss of soil structure and soil degradation. Conservation tillage and cropping intensification can improve soil structure in these areas. The objective of this study was to determine the influence of three different tillage systems (traditional tillage, reduced tillage and no-tillage) u...

Root growth, soil water content and yield of barley under different tillage systems on two soils in semiarid conditions

Cropping systems, tillage and fertilization strategies for durum wheat performance and soil properties

Many sustainable agronomical practices can be adopted to contain environmental risks of crop production and, at the same time, sustain yield and quality. In this framework, the aim of this research was to study the effects of continuous cropping (CC) and crop rotation, tillage and fertilization strategies on durum wheat (Triticum durum Desf.) production. The responses of soil properties we...

Microbial Community Composition as Affected by Dryland Cropping Systems and Tillage in a Semiarid Sandy Soil

This study evaluated microbial communities of soil (0–10 cm) as affected by dryland cropping systems under different tillage practices after 5 years. The soil type was an Olton sandy loam with an average of 16.4% clay, 67.6% sand and 0.65 g kg of organic matter (OM). The cropping systems evaluated were grain sorghum (Sorghum bicolor L.)— cotton (Gossypium hirsutum) (Srg-Ct), cotton-winter rye (...

The characteristics of overland ̄ow under varied tillage and cropping systems in Sichuan Basin, China

Data from runoff plots operated over a ®ve year period show that signi®cantly less overland ̄ow is generated with a seasonal no-till ridge system than with contour tillage or straight tillage systems. Seasonal no-till ridge is the optimum system for increasing the availability of water for rainfed agriculture on the dryland soils in the hilly area of Sichuan Province, China. # 2000 Published by...
