What Rosier does

Rosier S.A. is a Belgian mineral fertilizer manufacturer founded in 1880 in Frasnes, Belgium. The company produces complex granular, liquid, and water-soluble fertilizers for agricultural and horticultural customers, serving markets in over 110 countries through direct B2B sales and long-term strategic partnerships. Its product portfolio comprises four primary lines—ROSAFERT (complex granules for basal/top dressing applications), ROSALIQ (liquid fertilizers for foliar and fertigation), ROSALEAF/SOL (water-soluble products for drip irrigation and foliar use, including a premium Rosaleaf range), and ROSATECH (precision liquid fertilizers for soil and greenhouse substrates)—alongside specialized micronutrient products such as MANGANESEFLOW 44. Technical differentiators include even-granule nutrient distribution, low salt-index formulations for foliar absorption, and color-coded water-soluble products for ease of use.

Rosier operates two manufacturing facilities—in Moustier, Belgium (its founding headquarters and superphosphate production site) and Sas van Gent, Netherlands (acquired in 2006 as Zuid Chemie)—and in August 2025 opened a new strategic terminal at the Port of Antwerp-Bruges with storage capacity exceeding 70,000 tons. The company is privately held: Borealis AG controlled it from 2013, and Turkey's Yildirim Group acquired it in January 2023, making Rosier part of its global fertilizer division alongside sister companies including Croatia's Petrokemija d.d. (54.5% stake, 1.35 million tons annual capacity) and affiliated port operator YILPORT.

Rosier monetizes through direct sales of customized fertilizer formulations, with pricing determined per engagement rather than via public lists. The company is ISO 9001, ISO 14001, and ISO 45001 certified, GDPR-compliant, and led by Chairman/CEO Willy Raymaekers alongside Yildirim-appointed board members. Reported headcount is in the 101–250 range, and product distribution extends to agricultural and horticultural operations across over 110 countries.

Formulas adjusted to crop and soil needs with high available nitrogen content and accurate spreading due to even granular size and density.
• ROSALIQ Liquid fertilizers in solution or suspension form for foliar applications and fertigation, designed to address plant disorders and provide supplementary nutrition across all crop types. Features high formulation standards to avoid sedimentation and effective absorption due to low salt index.
• ROSALEAF/SOL Water-soluble fertilizers designed for drip irrigation and foliar applications, available in two ranges: Rosasol (standard powder formulation) and Rosaleaf (premium range optimized for leaf application). Features adapted formulations for all crops and growth stages, time-saving ready-to-use products, and color-coded identification.
• ROSATECH Precision tank-mix liquid fertilizers for soil or greenhouse substrate applications, offering tailored single-element or compound NPK+TE fertilizers with low salt index for optimal compatibility with foliar or fertigation methods.
