Comparison of the chemical changes in the rhizosphere of the nickel hyperaccumulator Alyssum murale with the non-accumulator Raphanus sativus
Changes in pH and redox potential were studied in the rhizosphere soil of a nickel hyperaccumulator plant ( Alyssum murale ) and of a crop plant,...

The Wageningen Rhizolab — a facility to study soil-root-shoot-atmosphere interactions in crops
A research facility is described for the integrated study of soil-root-shoot-atmosphere relationships in crops. The Wageningen Rhizolab has been in...

Above- and belowground response of Populus grandidentata to elevated atmospheric CO2 and soil N availability
Soil N availability may play an important role in regulating the long-term responses of plants to rising atmospheric CO 2 partial pressure. To further...

Impact of mycorrhizal colonisation on root architecture, root longevity and the formation of growth regulators
Until relatively recently, it was assumed that arbuscular mycorrhizal fungi (AMF) did not influence the morphology of the root system. (1983)...

Carbon Allocation to Root and Shoot Systems of Woody Plants
Carbon allocation to roots is of widespread and increasing interest due to a growing appreciation of the importance of root processes to whole-plant...

Control of Verticillium Dahliae by Catch Crops and Haulm Killing Techniques
Since non-hosts can induce germination of microsclerotia (MS) of V. dahliae, growing of non-hosts may reduce the inoculum potential in the soil. To...

Crop Reactions to Environmental Stress Factors
Agricultural productivity is strongly reduced by biotic and abiotic factors and much effort goes into breeding for stress tolerant varieties and into...

Modeling Root System Morphology in Rice
Although rice is one of the most important crops in the world, especially in Asia, and many agronomic studies have been done, information on...

A comparison of minirhizotron, core and monolith methods for quantifying barley (Hordeum vulgare L.) and fababean (Vicia faba L.) root distribution
Root research has been hampered by a lack of good methods and by the amount of time involved in making measurements. The use of the minirhizotron as...

A method for counting roots observed in minirhizotrons and their theoretical conversion to root length density
A method for counting root intersections with observation tubes (mini- or micro-rhizotrons) is proposed that allows a theoretical conversion of root...

Combined use of colorimetric and microelectrode methods for evaluating rhizosphere pH
Plant control of rhizosphere pH is important for nutrient mobilization and uptake, and also affects microbial activity and pathogens in the vicinity...

Alley crop**: past achievements and future directions
There is a need to develop viable farming systems for tropical uplands dominated by low-activity clay soils; such systems should ensure sustained...

A comparison between minirhizotron and monolith sampling methods for measuring root growth of maize (Zea mays L.)
Transparent plastic minirhizotron tubes have been used to evaluate spatial and temporal growth activities of plant root systems. Root number was...

Elevated atmospheric CO2 and feedback between carbon and nitrogen cycles
We tested a conceptual model describing the influence of elevated atmospheric CO 2 on plant production, soil microorganisms, and the cycling of C and...

Biomass and nutrient dynamics of dominant plant species from heathlands
Primary production, litter production, nutrient uptake and nutrient loss are important characteristics of the functioning of any ecosystem. They...

Wheat root biomass and nitrogen dynamics—effects of daily irrigation and fertilization
Root biomass, root nitrogen content, and root distribution down to 50 cm depth in winter wheat were determined by soil coring on five dates in four...

Implications of increased carbon dioxide levels for carbon input and turnover in soils
The complexity of the plant-soil system in its interaction with the changing climate is discussed. It is shown that processes at the level of organic...
