Our History

OGT was founded in 2004 here in Donegal along the North Atlantic coast of Ireland, our close proximity to the clean pristene waters of the North Atlantic have allowed the growth of a highly successful business with a customer base world wide with preferential access to the Ascophyllum nodosum seaweed and with an exclusive extraction method, Gentle Extraction, that preserves the biostimulating compounds that are naturally present in fresh seaweed.

In 2014 OGT was acquired by Tradecorp – an international company with expertise in micronutrients and speciality fertilisers. Founded in 1985 in Spain, Tradecorp has extensive experience in crop nutrition and using OGTs portfolio of specialist products allows clients to improve their crops and their business, while protecting the environment and the health of the food chain.

Tradecorp is owned by Rovensa, formerly known as Sapec Agro Business, an international player in the agricultural industry, with a long history, experience and knowledge in the sector.
In September 2019, Sapec was renamed Rovensa, with the aim of creating a prestigious international brand in the agricultural industry. The group is now organized into three main business units: crop protection, crop nutrition and biocontrol. With offices, factories, research centres and laboratories in Brazil, France, Spain, Portugal and Ireland, Rovensa continuously develops a broad portfolio of innovative solutions for plant health & care.
