About The Program
The California Almond Sustainability Program (CASP) documents the almond community's thoughtfulness and efforts to adopt cost-effective, environmentally and socially responsible practices. CASP achieves this through grower and handler assessment of current practices, and using aggregated results for communications, education and continuous improvement.

The CASP online system offers several interactive tools that are designed to streamline both crop input decision-making and regulatory reporting requirements. These tools include the Nitrogen calculator

The Nitrogen Calculator uses models developed by UC Davis plant scientist Dr. Patrick Brown and colleagues to predict how much nitrogen to apply and when to apply it to meet yield-based demand. To use this tool, growers enter their yield estimates pre- and post-bloom, and then add early-season tissue-sampling results. Using the nitrogen calculator can also satisfy all of the Nitrogen Management Plan reporting requirements of the Irrigated Lands Regulatory Program (ILRP).

for fertility plans and Mapping tool

The mapping tool allows users to draw boundaries of their fields and enter APNs (assessor's parcel numbers), and then drop pins to plot the locations of active or abandoned wells or observation wells, as well as discharge points and any other feature the grower wishes to record. Once the map is developed, users can create a map report that is required as Part D of the ILRP farm evaluation plan, and is also required to have on file for your Nitrogen Management Plan. These two tools are integrated so the information does not have to be entered twice.

For growers who have fields in multiple coalitions, which may have different reporting requirements, both the mapping tool and the nitrogen calculator allow the user to enter the name of the coalition and create separate reports for each coalition.

that also generates the Nitrogen Management Plan report required by the Irrigated Lands Regulatory Program (ILRP). In addition, the Irrigation calculator

The irrigation calculator is a popular tool for those who haven't invested in complex irrigation monitoring and reporting systems. It uses the latest UC research, and recommends the amount and timing of water to be applied to almond orchards based on evapotranspiration (ET).

Using active CIMIS stations, spatial CIMIS and historical climatic zones, the calculator can show both past and forecasted water demand for a whole season.

To use the calculator, growers enter information about their orchard, such as row and tree spacing, soil texture, root depth, etc., as well as some basic information about the irrigation setup for each field or block. Once entered, the calculator will update the weather information and calculate the run time for that system, as defined, that it would take to replace the water lost as calculated by ETc for that week.

generates irrigation run time schedules that advise the amount and timing of irrigations based on local ET and your individual orchard and irrigation system. All of these tools are available to you after you create an account and login.
