the probe about 1 cm.

 

Note that when using plug electrode must not touch the stone, do not use too much force,

otherwise easily damage electrodes clean the electrode after use.

 

Soil pH

Soil pH, also known as "soil reaction." It is the soil solution of the acid-base reaction.

Mainly depends on the concentration of hydrogen ions in the soil solution at pH values. pH of

the solution is equal to 7 neutral solution; pH of less than 7, the acid reaction; pH value greater

than 7 is alkaline reaction. Soil pH can generally be divided into the following levels:

pH of soil pH

<4.5 strong acidic

4.5-5.5 strongly acidic

5.5-6.5 Acid

6.5-7.5 neutral

7.5-8.5 Alkaline

8.5-9.5 strongly alkaline

> 9.5 strong alkaline

Soil pH on soil fertility and a great influence on plant growth, China\'s northwest, north many

soil pH value, pH value of small red soil. Therefore can be grown and adapted to soil pH and

plant crops. Such as acid red soil area planted hi tea, and strong alkali such as alfalfa. Soil pH

effects on nutrient availability is also great, such as neutral soil phosphorus availability large;

alkaline soil trace elements (manganese, copper, zinc, etc.) effectiveness is poor. In agricultural

production should be noted that the pH of the soil, and actively take measures to adjust.

 

Common crop optimum soil pH range is how much?

 

Soil pH on plant nutrient availability, soil structural and crop growth have a great relationship.

First, soil organic state by microbial nutrients to participate in activities in order to make it

into nutrients for plant uptake of available state, while the majority of microorganisms involved

in decomposition of organic matter in the near-neutral growth environment, so the effective soil

nutrient in general close to neutral reaction is the best. Secondly, structural soil pH also affects

the soil. Acidic soil, the hydrogen ion concentration, easy to colloids leaching out calcium

substitution, it is easy to acidic soil compaction. The substitution of the alkaline soil contains

large amounts of sodium ions and hydroxide ions, so that soil particles dispersed, dry compaction,

resulting in poor structural earth. In addition, soil pH and plant growth also has a very close

relationship. In nature, some plants on soil pH conditions demanding that they can only be in a

particular pH range grow, these plants from the soil pH can be indicative that, so called

indicator plants. Such as azalea only grow in acidic soils, known acidic soil indicator plants;

Kashiwagi is calcareous soil indicator plants, and salsa is an alkaline earth indicator plants.

Different cultivated plants have different optimum growth pH range (see table below),

knowing their respective optimal growth range, we can according to local conditions based on soil

pH, choose the right crops; or according to crop, adjust the soil pH to the proper range.
