MODELING SOIL WATER REDISTRIBUTION UNDER SURFACE DRIP IRRIGATION [PDF]
Engenharia Agrícola, 2019 The main objective of this study was to develop a numerical model to simulate water distribution, and the shape of the wetted soil volume, resulting from a point source irrigation at the ground surface (dripper), given soil hydraulic properties and ...

WATER REQUIREMENTS FOR IRRIGATED SUGARCANE UNDER TRICKLE IRRIGATION [PDF]
Misr Journal of Agricultural Engineering, 2008 Effect of irrigation water requirements and row spacing of surface and subsurface trickle irrigated sugarcane on soil moisture distribution, sugarcane yield, sugar percentage and water use efficiency were studied. There are three different lateral distance between plants (L) used in the experiment; 0.75 m, 1.00 m and 1.25 m under four irrigation ...

Backpressure effects on the flow-pressure relation of driplines [PDF]
Engenharia Agrícola, 2016 For drip irrigation design and management, it is necessary to know the relation between flow and pressure acting on emitters. In the case of subsurface drip irrigation, the backpressure phenomenon may change the hydraulic characteristics of emitters ...

Evaluation of irrigation and pruning on the phenology and yield of Theobroma cacao L.
Agronomía Mesoamericana, 2019 Introduction. It is believed that only 0.5 % of the area planted worldwide with cocoa is irrigated. Water availability influences the rate of expansion of the tree canopy and thus light interception.

Trickle irrigation systems affect spatial distribution of roots of banana crop
Revista Brasileira de Engenharia Agrícola e AmbientalTrickle irrigation has been largely used for banana in Brazil, mainly due to the increase in water and fertilizer use efficiency. These irrigation systems have different options concerning number, type and flow rate of emitters as well as for hydraulics,

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is managed after sinus surgery with topical corticosteroids. Given limited distribution of nasal steroid sprays, patients have the option of either steroid nasal irrigation (SNI) or exhalation delivery system with fluticasone (EDS‐FLU).
