Assessment of Southern California environment from ERTS-1

ERTS-1 imagery is a useful source of data for evaluation of earth resources in Southern California. The improving quality of ERTS-1 imagery, and our increasing ability to enhance the imagery has resulted in studies of a variety of phenomena in several Southern California environments. These investigations have produced several significant results of varying detail. They include the detection and identification of macro-scale tectonic and vegetational patterns, as well as detailed analysis of urban and agricultural processes. The sequential nature of ERTS-1 imagery has allowed these studies to monitor significant changes in the environment. In addiation, some preliminary work has begun directed toward assessing the impact of expanding recreation, agriculture and urbanization into the fragile desert environment. Refinement of enhancement and mapping techniques and more intensive analysis of ERTS-1 imagery should lead to a greater capability to extract detailed information for more precise evaluations and more accurate monitoring of earth resources in Southern California

Land use in the northern Coachella Valley

Satellite imagery has proved to have great utility for monitoring land use change and as a data source for regional planning. In California, open space desert resources are under severe pressure to serve as a source for recreational gratification to individuals living in the heavily populated southern coastal plain. Concern for these sensitive arid environments has been expressed by both federal and state agencies. The northern half of the Coachella Valley has historically served as a focal point for weekend recreational activity and second homes. Since demand in this area has remained high, land use change from rural to urban residential has been occurring continuously since 1968. This area of rapid change is an ideal site to illustrate the utility of satellite imagery as a data source for planning information, and has served as the areal focus of this investigation

Summary of 1972 seasonal results Decide superphosphate rates on pastures

A total of 53 pasture trials were topdressed. Of these, 37 trials were quantitatively assessed at different times during the growing season. Of the 15 wheat trials sown, only four trials gave useful results because of multiple drilling techniques used on most trials. Until the trial results have undergone comprehensive statistical analysis, no conclusions can be drawn. about the levels of response or optimum rates of superphosphate application at individual sites. However, because of the very short growing season in 1972 responses were generally poor. It appears that nil superphosphate application would have been optimum for animal production in the 1972 season at most sites. The following tables of results are attached: I. Location of Trials. II. Site Characteristics. III. Management and Assessment. IV. Yield data and Analysis of Variance - Pasture Trials.
