Our History

OGT was founded in 2004 here in Kilcar by Mr Declan Gallagher, Declan built 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 gained broad experience in crop nutrition, which offer clients to improve their crops and their business.

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.
