Welcome to J.K. Senior & Sons

We are crop consultants to the farmer. As independent agronomists, based in Yorkshire, we advise on seed, fertiliser and sprays. Please visit our Services page for more details.

Our large established Buying Group offers members exceptionally competitive rates for crop protection products. Because we are truly independent, our aim is the same as the grower, which is to provide peace of mind that we will only advise on the products that are required, at exceptionally competitive rates, as we do not sell or take commission on the products we recommend.

We hope that you find our pages useful and informative. We would welcome the opportunity to discuss your crop protection and consultancy requirements with you. Please contact us for further details.

Services We offer the full complement of agronomic services and associated advice.

Buying Group Group purchasing power enables us to secure competitive prices, which are passed directly to our members. Savings of up to 20% can be achieved.
