soil infiltration rate: Insert a coffee can with the ends cut off into the soil and pour in
approximately 1 inch of water. Note how long it takes to infiltrate the surface.
irrigation rate: Place a can on an area that is being irrigated and note the amount of water in the can after 15 minutes. This tells you how much water you are applying.
amount of precipitation: Leave a can in your yard to measure weekly amounts of
precipitation. To avoid runoff, precipitation or irrigation should not exceed soil infiltration.
lawn’s water needs: Healthy, actively growing turfgrass requires about 1 inch of water a week (by rain and/or irrigation).
best time to water: Water in the early morning to reduce evaporation and so plants dry by
mid-morning. Prolonged leaf wetness can lead to disease.
