Phosphate Fertilizer Testing

Phosphate fertilizer is a unit fertilizer with phosphorus as its main nutrient. Rational application of phosphate fertilizer can improve crop stress resistance, increase crop yield and improve crop quality. Although phosphate fertilizer promotes agricultural production, it can also bring negative effects. For example, phosphate fertilizer in soil will enter rivers, lakes and groundwater along with farmland drainage and rainwater, resulting in water eutrophication and threatening aquatic animals and human health. Excessive phosphate fertilizer can also cause harm to crops and is not conducive to crop growth. Therefore, it is very important to understand the composition, element content and performance index of phosphate fertilizer for rational application of phosphate fertilizer, promoting the development of agricultural production and protecting ecological environment.

STEMart provides comprehensive phosphate fertilizer testing services to assess the utility and safety of phosphate fertilizer, guide the scientific use of phosphate fertilizer, and maintain the balance between agricultural development and ecological health.

Test Samples

• Water-soluble phosphate fertilizer: phosphoric acid, mono-ammonium phosphate, ordinary superphosphate, diammonium phosphate, heavy superphosphate, potassium dihydrogen phosphate, etc.
• Citrate-soluble phosphatic fertilizer: calcium metaphosphate, steel slag phosphate fertilizer, calcium magnesium phosphate fertilizer, precipitated calcium phosphate, etc.
• Insoluble phosphate fertilizer: bone meal, phosphate mineral powder, etc.
