Smart controllers (commonly referred to as ET controllers, weather-based irrigation controllers, smart sprinkler controllers, and water smart irrigation controllers) are a new generation of irrigation controllers that utilize prevailing weather conditions, current and historic evapotranspiration, so...

Understanding Soil Water Holding Characteristicsz Pdf version The table below shows the plant-available water held by different textured soils when they are fully wet. Plant-available water is the amount of water stored in the soil that plants can take up.

Polyphagous Shot hole Borer Beetle. Photo by Gevork Arakelian Polyphagous Shot Hole Borer (Euwallacea sp.) is a recently detected beetle that can cause a Fusarium dieback on avocado and other host plants. The disease is caused by a new, yet unnamed Fusarium sp.

SLIDE (Simplified Landscape Irrigation Demand Estimation) is the most accurate and scientific method currently available for estimating the water demand of established landscapes.

In a landscape or other planted area, water from the soil moves to the atmosphere due to evaporation from the soil surface and transpiration from plants. This process is defined as evapotranspiration, or ET, which is a combination of the words evaporation and transpiration.

Research-based landscape plant factors (PF) and turfgrass crop coefficients (Kc) have been established (Table 1) and can be used to adjust reference evapotranspiration (ETo) data and estimate the water requirement of a plant type wherever it is grown.

Lawns and other turfgrass plantings closely match the standard conditions used for estimating plant water use with reference evapotranspiration (ETo) data, so true turfgrass Kcs have been scientifically determined.

Starting in 2015, landscape plants and the water they use began to experience unrelenting attack as California continues struggling with drought conditions and limited water supplies.

In the summer of 2003, the Municipal Water District of Orange County (MWDOC) received a grant to provide funding assistance for the installation of 1,700 smart irrigation controllers in residential and commercial sites in Orange County, CA.

Established landscape trees and other woody plants, in general, have effective drought resistance mechanisms and require only modest amounts of water to perform acceptably in landscapes, but the perception is they need greater amounts of water to perform well so they are usually over watered.
