Numerical Simulation of Water Distribution with Uptake Root in Drip Irrigation using Different Soil Hydraulic Models

Journal of Engineering, 2021
Surface drip irrigation is one of the most conservative irrigation techniques that help control providing water directly on the soil through the emitters. It can supply fertilizer and providing water directly to plant roots by drippers.

Backpressure effects on emitters flow rate in subsurface drip irrigation

Revista Brasileira de Engenharia de Biossistemas, 2022
Subsurface drip irrigation success depends on surpassing the backpressure obstacle, a phenomenon which occurs when the water application intensity exceeds the infiltration rate of soil, which reduces the emitter flow rate.

Evaluation of mobile trickle irrigation and sub-surface nanotechnology trickle irrigation by irrigating bean (cv. Veto)

IOP Conference Series: Earth and Environmental Science, 2021
Abstract Water resources are suffering from scarcity and deterioration their quality due to environmental dilution. Trickle irrigation is the best efficiency systems because it focuses on the root space only, omitting surface runoff and minimizing deep percolation losses.

Management of Microsprinkler Systems for Florida Citrus

EDIS, 2004
Irrigation is an essential part of the Florida citrus production system. In one study, irrigation increased yield by 39 to 64% over the non-irrigated controls. Microsprinkler irrigation systems have become the standard for Florida citrus. Microsprinkler
