ชุดทดสอบดินสำหรับ PH และธาตุ NPK
รุ่น HI3896 แบรนด์ HANNA

Description

- the HI3896 Soil test, it is possible to measure pH and the most important elements for plant growth: nitrogen (N), phosphorus (P) and potassium (K).
- The chemical composition of soil includes pH and chemical elements. Soil analysis is necessary for better management of fertilisation and to know the residues of fertilisers in relation to the crop, tillage and the most suitable plant choice for soil composition. An analysis can highlight shortages and help the understanding of the causes of an abnormal growth.
- Testing the soil during each crop cycle and comparing the results with plant growth can be a useful experiment for subsequent cultivation.
