Soil pH:Soil pH also known as "soil reaction." It is an acid-base reaction of the soil solution. Primarily depends on the concentration of hydrogen ions in the soil solution, expressed as pH.solution of pH = 7 neutral solution; pH of less than 7, the reaction is acidic; pH greater than 7 is alkaline. Soil pH can generally be divided into the following stages:The pH soil pH<4.5 strong acid4.5-5.5 strongly acidic5.5-6.5 Acid6.5-7.5 neutral7.5-8.5 Alkaline8.5-9.5 strongly alkaline> 9.5 strong alkalinespecification:Conditions: 100% brand newProject Type: Soil TesterColor: As shownBody dimensions: about 11 × 6 × 3 cm / 4.3 × 2.4 × 1.2 inchProbe length: about 16cm / 6.3 Yingcunpacking list:1 × soil tester1 × Manualnote:1. Due to manual measurement, allow 1-2cm error. thank you for understanding.2. inconsistent display calibration, color of the items displayed picture may differ slightly from the actual objects. Please refer to the actual subject.Instructions:1. Measurement PH value of the soil, the probe into the soil as deep as possible, approximately at 1 cm above the probe.2. Do not touch the rock when inserting the electrode. Do not use too much force, it will be very easy to hurt electrode. Please clean the electrode after use.
