33. clay may call for a switch to longer irrigation run times done on a less frequent basis Short irrigation runs have a tendency to deposit more salt in the root zone with possible adverse impacts on plant health and growth Clay soil is more susceptible to this phenomenon than better draining soils Heavier watering done less frequently helps to leach the accumulating salts out of the root zone This is particularly important in regions of the state that do not experience sufficient precipitation during the rainy season Rainfall can have the same effect as longer watering periods if the storms are heavy enough Periods of drought can exacerbate the build up of salts but can be addressed with a modified irrigation schedule NUTRIENTS Recycled water may also contain higher nutrient levels such as nitrogen phosphorous and potassium that are essential components for plant growth Some treatment processes may reduce the levels of these chemicals although they are not totally removed Fertilizer Value While nutrient levels vary among treatment plants there are usually sufficient levels of nitrogen phosphorous and potassium in the recycled water to provide at least a small measure of fertilizer value to the landscaping each and every time irrigation takes place Based on nutrient levels in the recycled water being supplied a Site Supervisor can readily calculate the number of pounds of each constituent being delivered He or she
