| Irrigation practices that are profligate in their use of water have come under closer scrutiny by water managers and the public. Trickle irrigation has the propensity to increase water use efficiency only if the system is designed to meet the soil and plant conditions. Information on moisture distribution patterns under point source trickle emitters is a pre-requisite for the design and operation of trickle irrigation systems. This will ensure precise placement of water and fertilizer in the active root zone. For many practical situations, detailed information on matric potential or water content distribution within the wetted volume is not necessary and prediction of the boundaries and shape of the wetted soil volume suffice. Simple models are more... |
