We developed a relatively simple installation device that minimized soil disturbance, especially suited for sensor installations at depths larger than about 70 cm (Fig. 1).

The spatial and temporal variation of soil water content in the root zone for the drip site is shown in Figure 2. The black and red arrows indicate the irrigation and rain events during the presented time period, respectively.

Members of the research teams are presenting their finding at regional, national and international conferences, professional meetings and grower group meetings. Below is a partial listing of these outreach activities in 2011 and 2012. Presentation may be downloaded (PDF) where indicated.

Nitrogen (N) is important for developing healthy, productive pecan (Carya illinoinensis K. Koch) trees. However, current applications of fertilizer generally follow a standard practice, without consideration of spatial, temporal and climatic variability.

The overall goal of this research project is to develop an integrated nutrient management practices for pistachio trees across different ranges of environments in California. The specific objectives of our work with long term and large scale pistachio project are discussed below.

Sampling & Analysis A five-year fertigation trial of nitrogen and potassium treatments is underway in almond orchard in Kern Co. The trial consists in 12 fertilization treatments under Micro-sprinklers (Fan Jet) and Drip irrigation.
