The best soil pH for Main Crops:

Orange, tangerine 5.0-7.0
1, if the soil is too dry or measurement points excessive fat parts, can not be measured when the soil pH, must first splash at the measurement point position, wait 28 minutes and then measured.
2, before using the measuring device must first polishing cloth, the metal parts of the absorption plate completely wipe clean to prevent influence the measured value. If not using the new metal plate surface with a protective oil, must first into the soil several times, mill net reservoir protection before use.
3, when the pH measurement point directly into the soil test, a metal plate surface must be completely buried, is the correct value obtained for about 10 minutes. Soil density, moisture and excessive fat parts may affect the measured values, it must be measured in several different positions, in order to average.
4, measured at 10 minutes after the pH is stable, then press the white button on the side, and humidity appear immediately.
