Location: Ipswich River Park, North Reading, MA
Details: One of four fields in a municipal athletic complex directly next to the river was redeveloped to reduce irrigation, fertilizer, and pesticide needs. Techniques included:
The remaining three fields received only the latter two treatments. The field immediately adjacent to the zeolite field - which had identical solar orientation, drainage, turf, and original soil profile – was used as a “control” in a study designed to evaluate the effectiveness of the zeolite.
In-kind cooperation: Town of North Reading
Irrigation controller supply, installation, and maintenance: AquaSave LLC, Ipswich, MA
Monitoring and Analysis: DCR and Tufts University with oversight from a Technical Advisory Committee
$15,000 for 20 tons of Zeolite
The town monitored irrigation demand and turf health of the zeolite field and the control field.
Weather settings on the irrigation controller were progressively adjusted for the zeolite and control fields, individually, until the most conservative watering regime that would still maintain healthy turf was identified for each field. Using these respective settings and a five-year period of detailed weather records, it was possible to simulate the number of irrigation cycles that would be triggered for each field over the five-year period and thus compare long-term irrigation demands of the two fields.
The addition of zeolite, a moisture- and nutrient-retaining additive, to the soil of an athletic field resulted in healthy turf with lower irrigation needs than the control field.
Average water savings, based on the model simulation described above, amounted to 38,400 gallons per acre per year, or a 37% reduction in water use.
