Usually yes. If the agronomist has an available employment-based route through the company's ordinary sponsorship, the Gold Card's nonrefundable fee and gift may be unnecessary. Compare the routes on requirements and timing using current official terms before committing money.
Sequence the comparison before the payment
The Gold Card framework, as described on the official page, ultimately routes a successful applicant through an employment-based immigrant category. A Kent employer that can sponsor its agronomist through that or another category directly may find that the Gold Card adds a large gift without changing the category's own requirements or visa availability. The sensible order is to have the employee's eligibility assessed first—education, experience, admissibility and the visa bulletin position for his country—and only then to decide whether the gift buys something the ordinary route does not.
If the company proceeds, it should time the processing fee to the point at which it has current official terms in hand, and the gift to the stage the program specifies after successful vetting. Terms may change between the decision and the payment; re-read the official page on the day the money moves, and note that a temporary status such as TN or L-1 for the interim period is a separate question with its own requirements.
