Manterra Ltd has it's roots in  a long established Yorkshire family farming business.    We have always been a business which is interested in new products and techniques which can add value.  Beginning with the import to the UK of the  Duport liquid fertiliser injectors we have gradually added cost effective and innovative products to the range that we offer.  Most of the products we offer we use in our own farming business or the research work that we do in conjunction with Stockbridge Technology Centre at Cawood.
