This report investigates the costs and benefits associated with the conversion from semi-enclosed seep irrigation to either automated seep or automated sub-drip irrigation for potato production in Northeast Florida. These costs and benefits are estimated at the level of the individual grower and for the public at large. The analytical tools in the report include financial budgeting and regressi...

Drip irrigation is presently widely recognized as the most efficient system that can be used in woody perennial crops. However, uncertainties exist on more appropriate agronomic design to employ. Here, we summarized research carried out for three seasons two young crops (persimmon and lemon) southeastern Spain. Several designs were compared by maintaining a similar amount of water application b...

Aerated irrigation (AI) has emerged as a method to mitigate rhizosphere hypoxia caused by wetting front with sub-surface drip (SDI). Increasing oxygen in processing tomato’s root zone is beneficial the improvement of gas environment, crop growth, yield and quality. The relationship between aerated quantity not clear. A total eight treatments, including four levels (4950 m3 hm−2 (W1), 4750 (W2),...

abstract- a detailed understanding of crop rooting systems will facilitate water use reduction, optimized nutrient uptake and irrigation scheduling more efficiently. a field experiment was conducted during 2005-2006 to investigate sugar beet rooting depth growth, irrigated with three irrigation methods (subsurface drip, surface drip and furrow) and two water qualities (recycled wastewater: ec= ...

The expansion of irrigated almond orchards in arid and semi-arid areas with scarce water available raises key issues related to the sustainability resources. A 3-year field experiment was conducted on a commercial young orchard located southeast Spain study effect two drip irrigation systems (surface, DI subsurface, SDI) crop growth their physiological responses under fully-irrigated conditions...

this research was designed to evaluate and compare the applicability of two different types of irrigation including traditionally (surface irrigation) and simple sub-surface drip irrigation (using pricked-pipe covered with plastic cloth). two plots containing 39 pistachio trees with 720 m2 area were selected in rafsanjan, iran. both plots were irrigated using exactly the same quantity and quali...

Rural areas represent approximately 95% of the 14000 km(2) Alabama Black Belt, an area of widespread Vertisols dominated by clayey, smectitic, shrink-swell soils. These soils are unsuitable for conventional onsite wastewater treatment systems (OWTS) which are nevertheless widely used in this region. In order to provide an alternative wastewater dosing system, an experimental field moisture cont...

where is the membrane time constant, is the membrane space constant, and V is the membrane potential. This equation describes the propagation of electricity along a core conductor, as some of the current escapes through a nonperfect insulator to an infinite external conductor. This cable equation was successfully adapted from the underwater telegraph to axons (4) and later to dendrites (9–12) a...
