Oklahoma Cooperative Extension Service Fact Sheets provide research-based information on a wide variety of topics including agriculture.

Ag Land Lease is an initiative between Oklahoma State University, Plant and Soil Science faculty and Agricultural Economics faculty, to bridge the gap between land owners and lessees.

The huge quantities of manure generated by animal feeding operations (AFO's) can be an economical source of plant nutrients and a valuable soil amendment to Improve Soil Quality and Maintain Soil pH.

This program is dedicated to the development of new bioenergy crops and their production systems and train Scientific Corps in Bioenergy Crop Production that will strengthen the efforts at Oklahoma State University.

Oklahoma is currently ranked second in the U.S. in canola acreage. Winter canola has proven to be a great option for crop rotation with winter wheat in the region.

Major responsibilities of the Cotton Team are to develop and conduct extension and applied research programs to inform Oklahoma producers as to best management practices for cotton production.

There are more than 8 million acres of introduced forages in Oklahoma that can be harvested either by grazing animals or as a source of stored forage. Due to the differences in soil types, precipitation amounts, and temperature gradients in Oklahoma, many forage species are managed for pasture and hay.

Land judging provides a unique opportunity for 4-H and FFA students to learn about land productivity, and conservation management. The home site evaluation contest teaches students about how soil properties and landscape position can impact a sites suitability for home construction.

These benefits of no-till are well documented and we hope the information available through this website will help you in managing your no-till cropping system or adopting no-till into your current cropping system.

This site is constructed to contain producer friendly information about nutrient management, fertilizer use, and precision fertilizer application.

Nitrogen use efficiency and/or fertilizer recovery in crop production systems can be computed using a wide range of methods.

The OSU Hand Planter is designed for developing countries. It will plant multiple crops and also apply fertilizer on a plant-by-plant basis.

There is no perfect or right crop rotation, but to use crop rotation can help improve the flexibility, intensity, and diversity of your production system.

This site provides links to different extension programs related to those modules and CCA certification, requesting CEUs for meetings electronically, online CEU calendar, and exam study resources.

The soil is a key foundation and unparalleled recycler and purifier across a catena that includes forest, range land, agricultural, urban and suburban and wetland ecosystems. Soil processes in these ecosystems allow the soil to perform functions that may be related to production, ecological regulation, biological habitat and engineering.

Each year the Oklahoma Cooperative Extension Service conducts performance trials in Oklahoma. These trials provide producers, extension educators, industry representatives, and researchers with information on hybrids marketed in Oklahoma.

Our research integrates principles and methods from soil chemistry, plant/microbial ecology, and mineralogy.

Here you can learn about our research and teaching activities and access information related to the discipline of soil physics.

The Soil, Water and Forage Analytical Laboratory (SWFAL) was established by the Oklahoma Cooperative Extension Service to provide soil testing, plant, animal waste and water analyzes for the State of Oklahoma and anyone who needs agricultural testing services.

This site is to provide current information regarding extension and research activities in weed management for all of Oklahoma’s crop production systems, resources for weed identification, and contact information for the weed science personnel at OSU.

This site is designed to serve as a resource for anyone interested in small grains production in the Southern Great Plains.

This team is committed to strengthening the Oklahoma wheat industry by enhancing its genetic resources, a mission that could not be accomplished without contributions from other state, federal, and private researchers.
