How To Use Web Tools

The Nitrogen Fertilizer Management Tool for California Wheat estimates grain yield and protein responses to in-season applications of N fertilizer. The tool combines site-specific weather and soil data with user-supplied, field-specific measurements & management information to produce real-time estimates of crop responses to added N fertilizer.

The Soil Nitrate Quick Test Web-Tool simplifies the process of interpreting a soil nitrate value so that users only have to select their location and input test results to receive an estimated lab soil nitrate value and an N fertilizer equivalent.

The University of California Small Grain Seeding Rate Calculator is a tool that helps determine seeding rates depending on the planting conditions and the average seed weights of different small grain varieties.

The California Weather Web-Tool provides location- and time-specific weather information for sites in the state of California.
