SIP rates should be viewed as the maximum
amount of water your lawn would need. Your lawn may need significantly
less water than the SIP rate calls for. This is based on your particular
conditions like type of soil, age of turf, shade and sun areas, percentage
of yard that is planted in shrubs and other perennials. Use the SIP
watering advice as a guide and experiment with the minimum amount
of water your personal landscape needs.
In
simple terms, determining the amount of water your lawn needs starts
by approximating water loss using factors like daily temperatures,
humidity, wind, solar radiation and rain. This is known as potential
evapo-transpiration (PET). A weather station in San Antonio records
the daily PET rate and this information is sent to Texas A&M each
day. They calculate the daily SIP rate and send it to us.
