Deciding on When to Irrigate Every crop has a threshold for how dry the root zone environment can get before yield and quality are compromised. Decreasing soil moisture past that threshold will inhibit plant transpiration, photosynthetic and metabolic processes, leading to decreased crop yield.

Nitrogen Management Among all essential plant nutrients, nitrogen (N) is the most unstable in the soil and also the most yield-limiting nutrient for berry and vegetable crops production in Ventura County.

Using the Soil Nitrate Quick Test (SNQT) for Guiding Nitrogen Fertilization The text below addresses the intricacies involved in using the SNQT to improve the efficiency of nitrogen fertilization practices. For specific details on how to use the quick test, click here or here.

CropManage is a free web-based irrigation and nitrogen management software created by the UC Cooperative Extension. The software uses multi-year local research data to estimate plant growth and therefore assess nitrogen uptake and water use.

Accounting for Nitrate in Irrigation Water With the increasing scrutiny and regulatory pressures to reduce nitrate leaching and nitrogen (N) fertilizer use, determining how much N is contributed from the irrigation water becomes important, especially in organic systems where the costs of N fertilize...

Choosing a Commercial Ag Laboratory Soil chemical analysis is the cornerstone of an effective nutrient management program.

Nitrogen Management Plan worksheet All Ventura County growers are now required by the Los Angeles Regional Water Quality Control Board to fill out the Nitrogen Management Plan (NMP) worksheet.
