Modeling Carbon Allocation below Ground
Belowground carbon expenditure has been difficult to measure, and even more so to predict. Root growth is influenced by both direct effects on plant metabolism and indirect effects of soil drying and interactions with soil organisms. In Concord grape, crop load may compete with root growth when soil moisture is not limiting. Root lifespan also is difficult to predict but some success can be ach...
متن کاملBelow-ground interactions in dryland agroforestry
This paper discusses the effects of intercropping and tree pruning on root distribution and soil water depletion in an alley cropping system with Acacia saligna and Sorghum bicolor in northern Kenya. Root distribution was determined by destructive sampling, and the soil water suction was measured with tensiometers and gypsum blocks, both up to 150 cm depth. The root systems of the intercropped ...
متن کاملAltered Precipitation Impacts on Above- and Below-Ground Grassland Invertebrates: Summer Drought Leads to Outbreaks in Spring
Climate change is predicted to result in altered precipitation patterns, which may reshape many grassland ecosystems. Rainfall is expected to change in a number of different ways, ranging from periods of prolonged drought to extreme precipitation events, yet there are few community wide studies to accurately simulate future changes. We aimed to test how above- and below-ground grassland inverte...
متن کاملEvaluation of ground reaction force in walking of below knee amputees based on sample entropy
Introduction: Abnormal pressure during daily activities, including walking, is known as a risk factor in knee joint degeneration in knee amputees. The aim of this research was to analyze ground reaction force (GRF) and sample entropy in below-the-knee amputees. Methods: This study was a descriptive-cross-sectional type, and 20 people with below-knee amputations of the right leg (TT group) and ...
