Checkerboard Barriers Attenuate Soil Particle Loss and Promote Nutrient Contents of Soil

Effect of Slope Gradient and Soil Physical Properties on Soil Loss in Furrows of Rainfed Farms

This study was conducted to investigate the effect of slope gradient and soil physical properties (grain size distribution, bulk density, aggregate stability and permeability) on water erosion in the furrows of rainfed farms under fallow conditions. The furrows with 6 m length were installed in five rainfed farms with 6.1, 10.6, 14.8, 20.7 and 27.1% slope steepness at three replications. Resul...

Simulating the interaction between plant roots, soil water and nutrient flows, and barriers and objects in soil using ROOTMAP

Plant productivity is directly affected by the capacity of the root system to forage for soil resources. An enhanced understanding of root-soil interactions provides the potential to improve crop performance in specific soil environments. Interactions between roots and soil are, however, complex. The root-soil environment is heterogeneous and difficult to visualise and measure, root architectur...

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...

Soil Acidification and Liming Interactions with Nutrient

Global Soil Nutrient Depletion and Yield Reduction

Nutrient depletion in soils adversely affects soil quality and reduces crop yield and consequently poses a potential threat to global food security and agricultural sustainability. With an emphasis on human-induced nutrient depletion, this paper described the causality among soil nutrient depletion, soil quality, crop production, socio-economic variables, and environmental condition. Then, glob...
