About Us

A Collaborative Approach

At Ochs Consulting LLC, we have a collaborative approach to crop consulting and an understanding that a “one size fits all” solution does not work in upstate New York Agriculture. Our team of professional consultants will work with you to get the right seed and right agronomic solutions for your operation.

We offer a full range of crop consulting services out of our office and warehouse in Trumansburg, NY.
