Fertilizer Testing Lab in India
A fertilizer's value comes down to what's actually in the bag — the nitrogen, phosphorus, and potassium levels, the moisture content, the micronutrients, and whatever impurities came along with the raw materials. SGM National Laboratory tests fertilizer products for manufacturers, distributors, exporters, agricultural businesses, and research organizations across India, from our facility in Udaipur, Rajasthan. If you need to confirm what a fertilizer formulation actually contains before it's sold, shipped, or applied, we can help.
Why Fertilizer Testing Matters
The nutrient balance in a fertilizer directly affects crop performance and soil health — get it wrong and the effects show up in a field, not just on a lab report. Testing gives manufacturers and buyers an objective answer to what’s in a batch, supporting quality control, formulation development, and specification compliance for chemical, organic, NPK, and micronutrient fertilizers alike.
Our Fertilizer Testing Process
Fertilizer Testing Parameters

| Moisture Content | Affects storage stability and product quality |
| pH | Acidity or alkalinity of the sample |
| Electrical Conductivity | Soluble salt and ionic content |
| Organic Matter | Quality indicator for organic and compost-based fertilizers |
| Micronutrients | Zinc, iron, manganese, copper, boron, and other specified elements |
| Particle Size | Distribution in granular or powdered fertilizers |
| Bulk Density | Mass per unit volume, relevant to physical quality |
| Solubility | How well the fertilizer dissolves in water under specified conditions |
| Chloride / Sulphur | Tested when required by product specification |
| Heavy Metals / Contaminants | Checked against product requirements when specified |
