Why conduct soil sampling for crops? The answer is simple and intuitive for most involved in agriculture. Regular soil sampling, testing, and associated guidance on fertilization and soil amendments help develop and maintain more productive and healthy
Deficit irrigation strategies with varying effectiveness can be employed in many cases to maximize production and profit. These strategies can include modifying irrigation schedules, concentrating irrigation to critical crop growth stages, reducing rates,...
It is important to consider the possible hydrologic impacts of irrigation optimization efforts to avoid implementing practices that have little appreciable effect relative to the desired outcome. Examples of desired outcomes include increasing supply reli...
A VFD can make sense in a variety of irrigation applications. Here are 6 of the major applications where one might consider a VFD (also see Henry and Stringham, 2013 and USDA-NRCS, 2010):
If you are connected to a municipal system, your water is probably categorized as “culinary or municipal water” and is used for everything from drinking and bathing to washing the car to watering tomatoes. However the Utah Division of Water Rights takes a...
Alfalfa is the most important crop in Utah, both in terms of acreage and revenue. Although often overlooked, one of the most critical decisions made in alfalfa production is determining which variety to plant. This report summarizes dry matter (DM) yields...
Enterprise budgets are the building blocks of a farm or ranch. They represent estimates of income and expenses for a specific period of time using a set of production practices and inputs for that enterprise. This research contains sample costs and return...

To protect your investment in agricultural pesticides, a boom sprayer should be calibrated at the start of the season and whenever application conditions change. Also, sprayer output should be periodically checked throughout the season to assure proper ap...
In Utah, there are typically three generations of corn earworm (CEW) each year. The first generation of adults either come from overwintering pupae (southern and central Utah) or migrate into northern Utah. The adult moth is tannish brown with a 1 1/2 inc...
Pesticides are substances that control unwanted organisms. A pesticide can be used to prevent, destroy, repel, or mitigate pests. Common pest organisms include insects, plants, fungi, bacteria, plant-parasitic nematodes, viruses, snails and slugs, and nui...
