This publication provides information you will need for measuring soil water: types of soil-water measuring devices, how to select the right measuring device and how to prepare and install these devices.
This publication presents basic information on factors (veil, water and plant relationships) to be considered in developing an effective irrigation schedule.
This publication explains how you can make the most efficient use of water and energy by applying the right amount of water to cropland at the right time.
This publication provides a step-by-step description of how to use the gravimetric method to calibrate soil-water measuring equipment.
Under the Tar-Pam Rules, the Basin Oversight Committee (BOC) is tasked with submitting agricultural information on a yearly basis. Unfortunately, some of this information, such as fertilizer rates, is based on best professional judgment; there are no fertilizer-use statistics that are reliable. In addition, best management practices (BMPs) are only captured if they are cost shared. To obtain a better estimate of agricultural practices, this one-time statistically valid area sampling frame was applied to agricultural fields in the Tar-Pamlico River Basin in order to collect an agricultural baseline of cropping systems, soil types and currently used best management practices. In summary, when all the data are combined, it appears that producers in the Tar-Pamlico River Basin are minimizing environmental impact of nutrient and soil losses from agricultural fields. Best management practices are being used, including buffers, water control structures, cover crops, and conservation tillage. Nutrient inputs generally are below recommended levels. The only area where we believe producers could improve management is by following soil test reports and reducing phosphorus fertilization.
This publication discusses irrigation decisions that affect water and energy efficiencies.
