FRONTLINE SERVICES

1. SOIL ANALYSIS

Soil analysis or soil testing is a tool to diagnose fertility status of soil. It determines the amount of essential nutrients in the soil, and if deficient, allows the recommendation of the right kind of fertilizer or other soil ameliorant at the right amount and timing of application.

3. SPECIAL ASSAY TEST (FOR FERTILIZER& PLANT TISSUE)

Fertilizer analysis (inorganic or organic) is done to determine if the guaranteed analysis printed on the product label is accurate or true. For new organic products, the test determine the nutrient content of the product and whether it passes the standard nutrient requirement set by FPA for organic fertilizer materials.

Assay of plant tissue is done to determine nutrient absorption capacity of crops under given set of soil and other environmental conditions. Tis is mostly done for research purposes.
