Evapotranspiration Controllers in a Humid Climate
The objective of this article is to present summary findings of multiple research studies concerning evapotranspiration (ET) controllers. Each study provided unique information concerning the performance and implementation techniques necessary to ensure successful integration with irrigation systems to optimize scheduling for water conservation. Based on these studies, ET controllers have the p...
متن کاملSimulation modeling of soil and plant nitrogen use in a potato cropping system in the humid and cool environment
With rising environmental concerns for current practices of fertilizer N management in the humid and cool areas, we simulated soil N dynamics and plant N use in the potato (Solanum tuberosum L.) cropping system using the software Stella. The objectives were to predict inseason N requirements by the potato crop, tuber yield, N uptake, N partitioning within root, leaf, stem and tuber, and N loss ...
متن کاملShort-term responses of soil physical properties to corn tillage-planting systems in a humid maritime climate
The fertile, but naturally poorly drained soils of the western Fraser Valley in British Columbia, Canada are located in an area subject to about 1200 mm of rainfall annually. These soils were under intensive conventional tillage practices for years, which contributed to their poor in®ltrability, low organic matter, and overall poor structure. Development of tillage practices that incorporate wi...
متن کاملSensitivity of Soil Respiration to Variability in Soil Moisture and Temperature in a Humid Tropical Forest
Precipitation and temperature are important drivers of soil respiration. The role of moisture and temperature are generally explored at seasonal or inter-annual timescales; however, significant variability also occurs on hourly to daily time-scales. We used small (1.54 m(2)), throughfall exclusion shelters to evaluate the role soil moisture and temperature as temporal controls on soil CO2 efflu...
متن کاملPlant-soil interactions in multistrata agroforestry in the humid tropics
Multistrata agroforestry systems with tree crops comprise a variety of land use systems ranging from plantations of coffee, cacao or tea with shade trees to highly diversified homegardens and multi-storey tree gardens. Research on plant-soil interactions has concentrated on the former. Tree crop-based land use systems are more efficient in maintaining soil fertility than annual cropping systems...
