Interactions among leguminous trees, crops and weeds in a no-till alley cropping system
Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...

متن کاملMaximum soil organic carbon storage in Midwest U.S. cropping systems when crops are optimally nitrogen-fertilized
Nitrogen fertilization is critical to optimize short-term crop yield, but its long-term effect on soil organic C (SOC) is uncertain. Here, we clarify the impact of N fertilization on SOC in typical maize-based (Zea mays L.) Midwest U.S. cropping systems by accounting for site-to-site variability in maize yield response to N fertilization. Within continuous maize and maize-soybean [Glycine max (...
متن کاملEffects of Land Use Change for Crops on Water and Carbon Budgets in the Midwest USA
Increasing demand for food and bioenergy has altered the global landscape dramatically in recent years. Land use and land cover change affects the environmental system in many ways through biophysical and biogeochemical mechanisms. In this study, we evaluate the impacts of land use and land cover change driven by recent crop expansion and conversion on the water budget, carbon exchange, and car...
متن کاملCompanion Crop Recommendations for Planting with Black Walnuts
The concept of planting trees in widely spaced rows and growing cash crops in the alleyways is a special form of agroforestry called alley cropping. To be successful, the companion crop’s physiological requirements (i.e., light, water and nutrients) must be accommodated by the tree. Black walnut’s (Juglans nigra L.) foliage and root system are unique and readily adapted to the growth of compani...
