RESEARCH

Since 1990, FREP has funded research on many of California’s important and environmentally sensitive cropping systems. This database aims to make the wealth of information contained in FREP research projects available, understandable, and convenient for growers to implement. See the Crop Fertilization Guidelines for tips on how to improve nutrient management, based on information gleaned from research.
