1989年，罗德岛州的水务专业人员开发了一个家庭草坪灌溉计划，该计划采用了农业土壤水分模型，用于家庭草坪。该项目只强调补充浇水，其关键是“水因素”，它是根据两种土壤质地上草坪的日常模拟模型开发的。该项目于1990年进行了试点测试，并在1991年的生长季在全州范围内运行。模拟模型依靠一个气象站获取水分数据。对降雨量的分析表明，家庭草坪的计算机灌溉计划需要明确的空间数据。生根深度和土壤成分等因素的可变性引起了对建议准确性的额外担忧。得出的结论是，东北部基于农场的计算机化灌溉调度程序不容易适应大面积的家庭草坪水管理。 相反，重点应该放在将洒水器校准率与土壤类型联系起来。郊区也应该鼓励低维护的绿化。包括17个参考文献、表格和图表。

In 1989, water professionals in Rhode Island developed a program for home lawn irrigation scheduling that adapted an agricultural soil moisture model for use on home lawns. The key to the program, which emphasized supplemental watering only, was a "water factor" that was developed from daily simulation models for lawns on two soil textures. The program was pilot-tested in 1990 and ran statewide in the 1991 growing season. The simulation model relied on a single weather station for moisture data. Analysis of rainfall amounts suggested that computerized irrigation scheduling for home lawns requires spatially explicit data. Variability in factors such as rooting depth and soil composition caused additional concern about the accuracy of the recommendations. It was concluded the computerized farm-based irrigation scheduling programs for the Northeast cannot be easily adapted to home lawn water management over a broad area. Instead, emphasis should be placed on linking sprinkler calibration rates to soil types. Low-maintenance landscaping also should be encouraged in suburban areas.
