As Kenya battles challenges in soil degradation and micronutrient deficiency, Zinc Sulphate has emerged as a vital input in revitalizing farmlands and boosting crop yields. At the heart of this transformation is a trusted supply chain — and Vinipul Chemicals is proud to support it.
This blog explores how our export-grade Zinc Sulphate is improving agricultural output across Kenya’s maize belts, tea plantations, horticulture zones, and smallholder networks.
What Is Zinc Sulphate and Why It’s Essential in Agriculture?
Zinc Sulphate (ZnSO₄) is a water-soluble inorganic compound used as a zinc fertilizer. It contains zinc (Zn) in a plant-available form and is used to correct zinc deficiency in soil and crops.
🔍 Voice Answer: Zinc Sulphate improves crop root development, boosts chlorophyll production, enhances flowering, and prevents stunted growth — especially in zinc-deficient soils.
Why Zinc Deficiency Is Common in Kenyan Soils
Kenya’s agriculture relies heavily on rain-fed farming, continuous cropping, and acidic soils in several regions. These factors lead to:
- Depletion of micronutrients like zinc
- Reduced crop uptake due to soil pH
- Low fertilizer use intensity in smallholder farming
The result: Widespread zinc deficiency in maize, beans, rice, and horticulture, leading to poor germination, small leaves, delayed flowering, and low yields.
Impact of Zinc Sulphate on Kenyan Crop Performance
Field trials and agricultural extension programs in Kenya have shown Zinc Sulphate application:
- Increases maize yield by 10–30%
- Improves disease resistance in beans and vegetables
- Enhances quality and size of tomatoes, onions, and bananas
- Supports better nutrient use efficiency in blended fertilizers
Zinc Sulphate is now a key recommendation in Kenya’s Integrated Soil Fertility Management (ISFM) programs.
How Vinipul Chemicals Supports Zinc Sulphate Supply to Kenya
Vinipul Chemicals ensures that Kenyan farmers — whether large-scale agribusinesses or smallholder cooperatives — receive high-quality, agriculture-grade Zinc Sulphate that’s ready for field use and compliant with Kenya’s import norms.
Our Zinc Sulphate is:
- 98%+ pure with 21–33% zinc content (based on mono or heptahydrate grade)
- 100% water-soluble, ideal for foliar spray and soil application
- Packaged in UV-stabilized, moisture-resistant bags for humid or semi-arid storage
- Supplied with COA, MSDS, Phytosanitary Certificate, and SGS (on request)
We ship bulk orders via sea to Mombasa Port, supporting Kenya’s growing agri-sector across counties like Nakuru, Eldoret, Kiambu, Meru, and Kisumu.

H8: Case Study: Helping a Kenyan Maize Cooperative Improve Yields
A farming cooperative in Uasin Gishu County faced stunted maize growth and poor flowering. Soil tests revealed a significant zinc deficiency.
Vinipul supplied Zinc Sulphate Monohydrate 33% within 3 weeks to Mombasa Port with full compliance.
Results after one harvest:
- Germination improved by 12%
- Maize ear length increased by 20%
- Net profit per acre rose by 18%
- Cooperative signed a recurring 50-ton seasonal contract
Zinc Sulphate vs Other Zinc Sources – Why It Works Best in Kenya
