This brochure goes over calibration guidelines for backpack or knapsack sprayers.
Proper application of pesticides and fertilizers is possible only with a sprayer or spreader that is accurately calibrated. When equipment is not correctly calibrated, it is easy to apply too much or too little of a chemical, which may result in the lack of pest control, damage to turf, wasted money, and/or contaminated environment. This publication explains how to calibrate boom sprayers and granular spreaders used on turfgrass.
Selecting the right tool for a job is essential. When that tool is as important and expensive as a farm implement, the same holds true—you want to buy farm equipment that does what you want; is strong, durable, and reliable; and is generally the best value for your money.
This publication offers information and guidance on how to clean and recondition tractors that have been submerged in floodwaters.
This publication explains the weight-area method, one of the two methods in which solid or semi-solid applicators can be calibrated. Proper calibration is required by law.
This publication explains the load-area method, one of the two methods in which semi-solid animal waste applicators can be calibrated. Proper calibration is required by law.
This publication covers cleaning and calibrating chemical application equipment, such as dusters, spreaders and sprayers.
This publication describes hose drag systems and their operation as used to apply animal waste and wastewater in North Carolina.
This publication, chapter 15 of the 2025 Cotton Information handbook, provides information on sprayer calibration for applying chemicals in cotton production.
The home water treatment industry has expanded tremendously in recent years. New products are constantly being introduced which claim to solve a variety of water quality problems. Consumers often make costly decisions about water treatment equipment without being well-informed. Many people simply do not know what questions to ask to ensure wise investments. This fact sheet offers the 12 questions consumers should ask of water treatment manufacturers or distributors.
For calibration to be successful, several items need to be taken care of before going to the field. Calibration will not be worthwhile if the equipment is not properly prepared. Calibration should be performed using water only. Follow the steps outlined below to prepare spraying equipment for calibration.
This publication offers general information and guidance on how to recondition farm equipment that has been submerged in floodwaters.
This publication describes the major systems used in farm equipment and outlines basic maintenance procedures that equipment operators can use to enhance performance and efficiency.
Expanding organic grain markets have increased interest in mechanical weed control. Learn how the rotary hoe can be used to control weeds in large-seeded grain crops such as corn and soybeans.
This publication contains step-by-step guidelines for field calibration of hard hose and cable tow irrigation systems. Proper calibration is required by law.
This publication for tobacco growers describes steps that can be taken to avoid or minimize tobacco curing losses due to an electrical outage.
This training program is designed to provide operators of animal waste management systems with the basic understanding needed to operate and maintain these systems in an efficient and environmentally sound manner. This manual is not intended to provide all of the technical details for the complete design of a waste management system or an approved animal waste management plan.
Hose-drag-type equipment has gained popularity in recent years for land application of wastewater in North Carolina. It offers several advantages over traditional irrigation systems including odor reduction, nitrogen conservation, and a relatively high flow rate that cuts the application time. This publication explains calibration procedures for the “low-profile-type” discharge system and a “boom-type” system.
