รุ่น HI3895 แบรนด์ HANNA

Description

HI3895 combination test kit for agriculture allows you to test pH, nitrogen, phosphorus and potassium which are all important for the quality of soil.
In agricultural applications, monitoring the quality of the soil is extremely important for the health and growth of crops. The pH level is an excellent guide as to which plants may thrive in a particular terrain, as well as indicating which conditioners and fertilisers to use.
Hanna's quick soil test provides growers with an economical way to quickly test pH as well as the three basic elements needed for a healthier plant: nitrogen (N), phosphorus (P) and potassium (K).
