Information about the cooperation with Agroplanta!

For several years, German open field cultivation has been leaning towards regenerative and sustainable agriculture. The company Agroplanta has developed a new soil adjuvant called Trillus® which, through an interplay of two carefully selected, patented microorganisms (Pseudomonas fluorescens and Trichoderma harzianum), is intended to improve nutrient efficiency and yield in conventional and organic cultivation. After the first promising test results in Colijnsplaat in the Netherlands, the official market launch is now taking place, reports Friedrich Boecker (right), distribution manager of the company.
