Abstract:
... Factors that affect wind erosion such as surface vegetative and other cover, soil properties and surface roughness usually change spatially and temporally at the field-scale to produce important field-scale variations in wind erosion. Accurate estimation of wind erosion when scaling up from fields to regions, while maintaining meaningful field-scale process details, remains a challenge. The object ...

Abstract:
... Biological control can contribute to the sustainability of crop/land management systems by reducing the inputs currently derived from non-renewable fossil energy sources. Biologically based technology will have to be developed and gradually integrated into management systems that will include some chemicals for a long time to come. A researchable paradigm is presented: using "weed-suppressive soil ...

Abstract:
... Winter oilseed rape (Brassica napus L.) is the dominant oilseed crop in northern Europe. Generally, it requires high amounts of nitrogen (N) but is characterized by low N-efficiency, which is defined as produced seed dry weight per unit of accumulated N-fertilizer. Consequently, there is a strong need to resume all the relevant information on N in relation to cropping of winter oilseed rape and en ...

... The mortality of cacao fruits caused by early fruit abortion or insect and pathogen attacks was investigated in differently managed agroforestry systems in Central Sulawesi, Indonesia. Nine agroforestry systems shaded by three different types of tree stands were selected, which represented a decrease in structural heterogeneity: forest remnants, diverse planted trees and one or two species of plan ...

Abstract:
... The ecology of maize (Zea mays L.) in Mexico, its center of domestication and diversity, has been researched for several decades. While the broad outlines of diversity and dynamics of native maize populations are known at the farm and national levels, these topics are less well known at the landscape level. Although environmental factors are the principal forces behind the overall diversity of the ...
