Test paper is the simplest method to determine pH value of soil directly(7 gallon nursery pots wholesale). The pH value of soil refers to the pH value of soil solution. If pH is greater than 7, it is alkaline; if pH is equal to 7, it is neutral; if pH is less than 7, it is acidic. Soil organic matter is composed of inorganic particles of different sizes(72 cell propagation trays wholesale), easy to cultivate, mainly including minerals, Platycladus orientalis, soil particles and silica formed by long-term weathering of rocks.


(cheap plastic nursery trays wholesale direct brazil)During the determination, a small amount of culture soil is put into a clean glass cup(gallon pot), diluted and stirred with cold boiled water according to the ratio of soil to water 1:1. After precipitation, the litmus test paper is put into 1 minute and then taken out. The color of the test paper after discoloration is compared with the standard sample plate(128 cell seed trays wholesale). The soil with unsuitable acidity and alkalinity can be adjusted accordingly.
