Effects of compaction and cover crops on soil least limiting water range and air permeability

Crop rotations that include tap-rooted species of cover crops may help alleviate the deleterious effects of soil compaction on plant growth by modifying soil physical properties. We studied the effects of compaction and cover crops on the least limiting water range (LLWR) and air permeability in the surface layers of a loamy (Exp. 1) and a sandy soil (Exp. 2). There were three compaction treatm...

Predicting Water Permeability of the Soil Based on Open Data

Water permeability is a key concept when estimating load bearing capacity, mobility and infrastructure potential of a terrain. Northern sub-arctic areas have rather similar dominant soil types and thus prediction methods successful at Northern Finland may generalize to other arctic areas. In this paper we have predicted water permeability using publicly available natural resource data with regr...

VARIATION IN SOil WATER AND SOil AIR CONTENTS ASSOCIATED WITH A VEGETATION - SOil SEQUENCE IN

SU.M~IARY: This paper describes part of a study of vegetation/soil system dynamics in which d~e re]ationships were demonstrated bctween structuraJ chang<' of the forest, with"associated changes in composition, and changes in otganic matter and soil physical properties, particularly the quantities cf water and air in non-capillarypores. Becausc of these rcsults an a.nalysis,\','as made of the qu...

an investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation

the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...
