Water used for turfgrass/landscape irrigation represents a significant portion of the total water used in Florida. This area of water use is increasing with population growth, which is projected to rise from 17 million to 20 million by 2015. If current water use trends continue, many areas will experience severe water shortages. Smart Water Application Technology (SWAT™) consists of irrigation controllers that establish or modify irrigation scheduling based on soil/weather variables. This paper summarizes the research carried out in Florida, regarding the use of ET controllers, soil moisture sensor controllers and rain sensors on turfgrass/landscape irrigation; and evaluates their effectiveness for irrigation water conservation. Testing locations range from plot scale on turfgrass and landscape material to cooperating home sites. Results have shown that controllers can cut irrigation as much as 90% during rainy periods and 41% during dry periods while maintaining turfgrass quality. Preliminary results in the residential arena show that soil moisture sensors and rain sensors could also save a significant amount of irrigation water when implemented (up to 50%). None of the SWAT™ controllers tested have shown a reduction in turfgrass/landscape quality when correctly set/implemented.

Summary The rumen contents were collected from fifty-one female Grant's gazelles and eighteen males, sampling of the females taking place at an average of four per month during a 1-year period. The rumen samples were analysed for their browse to graze ratio, as shown by the dicotyledon to monocotyledon ratio, the primary objective being to determine whether the degree of pregnancy with its inferred changing nutritional demands, influenced this ratio. Other factors investigated were rainfall as related to grass availability, age of the individuals and sex. The results suggested the species to be primarily a browser, taking an average of 65.8% browse and 34.3% graze. The most significant factor affecting browse to graze intake appeared to be rainfall as related to grassland flushes. No other significant influences were detected. Resume On a recolte les contenus du rumen de cinquante et une femelles et dix-huit mâles de gazelle de Grant, et I'echantillonnage des femelles eut lieu en moyenne yuatre fois par mois durant une periode d'un an. Les echantillons furent analyses pour etablir le rapport dicotyledones/monocotyledones de leur regime; l'objectif de base etant de determiner si le stade de gestation, qui entraine un changement des besoins alimentaires, influence ce rapport. Les autres facteurs examines furent les pluies, qui regissent la presence des graminees, 1'âge des individus et le sexe. Les resultats suggerent que l'espeke est d'abord un brouteur de feuilles, mangeant une moyenne de 65.8% de feuilles et 34.3% d'herbe. Le facteur le plus significatif regissant la consommation de feuilles ou d'herbe semble etre les chutes de pluie donc la pousse des pâturages. Aucune autre influence significative ne fut detectee.
