Tri-State Performance Objectives

The Certified Crop Adviser (CCA) Program is an educational program with two main goals: to certify individuals who have passed a minimum competency examination and to establish a mechanism of continuing education for those already certified.

Technical Service Provider Program (TSP)

Technical service providers (TSPs) offer services to agricultural producers such as farmers, ranchers, and private forest landowners on behalf of the Natural Resources Conservation Service (NRCS). TSPs help these producers plan, design, and implement conservation practices or develop conservation activity plans to improve agricultural operations.

American Society of Agronomy

The American Society of Agronomy (ASA) is a progressive international scientific and professional society that empowers scientists, educators, and practitioners in developing, disseminating, and applying agronomic solutions to feed and sustain the world.

Ohio Certified Crop Adviser of the Year Award

The Ohio Certified Crop Adviser of the Year award was designed to recognize individuals who are highly motivated, deliver exceptional customer service for farmer clients in nutrient management, soil and water management, integrated pest management and crop production and have contributed substantially to the exchange of ideas and the transfer of agronomic knowledge within the agricultural industry in Ohio.
