A better awareness of soil and crop condition variability within fields brought the notion, in the early 1980s that variable management within fields by zones rather than whole fields would increase profitability by doing the right thing at the right place in the right way. At the same time, the microcomputer became available and made possible the acquisition, processing, and use of spatial field data as well as the development of a new kind of farm machinery with computerized controllers and sensors. Precision agriculture (PA) has been considered for most common cropping systems and some specialty crops, worldwide. It is particularly well adapted to high value crops such as many horticultural crops. PA is still in infancy and its adoption varies greatly but precision agriculture is the agricultural system of the future. It offers a variety of potential benefits in profitability, productivity, sustainability, crop quality, food safety, environmental protection, on-farm quality of life, and rural economic development.

The Festival of Color is the annual plant and landscape open house sponsored by the Univ. of Nebraska's Horticulture Dept. The festival is the culmination of many water-centered activities that have preceded the festival throughout the year. Last year's September event drew over 10,000 people to the UNL Agricultural Research and Development Center near Mead, Neb. The festival was created to increase the urban public's awareness and motivation regarding the best landscape management practices for developing environmentally compatible landscapes and reducing urban runoff of water and pesticides. The Festival of Color is an event for all ages. By including the activities for the entire family, the festival draws a large spectrum of the urban population. The festival has grown steadily from 850 visitors in 1993 to 10,000 in 1998. The festival will continue to include demonstrations and talks on selection, installation, and management of turf; irrigation equipment and management methods; pesticide selection and pest management alternatives; fertility management alternatives; low input landscaping with native and adapted species; composting; and more. At the Sixth Annual Festival of Color: 1) 42% of new attendees learned how to implement water conserving landscape techniques (66% of the previous attendees implemented water conserving landscape practices), 2) 30% of new attendees learned how to irrigate more efficiently (63% of previous attendees used water more efficiently), and 3) 29% of new attendees learned how to fertilize more efficiently (actual positive behavior change was higher than the proposed change reported by first time attendees), 4) 98% of new attendees learned how to choose plants based on site/location “Right Plant, Right Place” (86% of previous attendees have improved their plant selection skills by putting the right plant in the right place).

This computer program, delivered-on a CD-ROM disc, develops a list of tree species and cultivars suited for a specific planting site. It requires little previous computer experience or tree knowledge to operate. Using multiple choice questions, the program automatically brings the user through above ground and below ground site analysis. This includes all the considerations known to influence proper species section for a planting site. Using C++ programming and the NASA-developed expert system shell called CUPS, a list of facts is generated as the user answers the questions. At the press of a button, the program finds trees that match the attributes the expert system placed on the facts list. The list can be further modified by choosing among ornamental and other tree attributes that might be of interest to the user. The tree list can be printed in several seconds. A typical run through the expert system takes 2 to 4 minutes to answer about 20 to 25 questions. The program contains data on 681 trees, more than 1,800 color photographs, and a 4-page fact sheet including 3 line drawings for each tree totaling more than 2,000 pages. The program can also be used as a reference by paging through the tree records to find information about specific trees. Each tree record lists on the computer monitor a large variety of data for the tree, allows you to view text about the tree, displays a line drawing of the entire tree, and displays up to seven photographs of each tree. The program will be distributed nationwide as a tool to help landscape architects, horticulturists and others select the right tree for the right place.
