Soil pH – Gramophone

How to know the pH of soil and its benefits in crops

Soil testing can detect not only the soil pH but also the electrical conductivity, organic carbon, major nutrients, and micronutrients.
The normal, acidic or alkaline nature of soil can be ascertained from soil pH value. Soil pH decreasing or increasing affects the growth of plants.
After finding out Soil pH, suitable crop varieties are recommended in problem-prone areas which can tolerate acidification and alkalinity.
Nutrients are most commonly received by plants between values 6.5 to 7.5 Soil pH. That is, the plant gives good yield with total growth. On the other hand, the value is less than 6.5 pH, the land is acidic and If the value exceeds 7.5 pH, the land is called alkaline.
Adding lime for acidic land and gypsum for alkaline land is generally recommended.

pH value of soil

It shows the reaction of soil, whether the soil is normal, acidic, or alkaline in nature. Decreasing or increasing soil pH affects the growth of plants.
Suitable varieties of crops are recommended in problematic areas. Which has the ability to tolerate acidification and alkalinity?
Nutrients are most commonly received by plants between values 6.5 to 7.5. soil pH. When the value is less than 6.5 the land is acidic and if it is more than 7.5 the land is alkaline.
Recommendation to add lime for acidic land and gypsum for alkaline soil.

Electrical conductivity

Soil electrical conductivity (EC) is an indirect measurement that has a very deep correlation with the physical and chemical properties of soil. Soil electrical conductivity is an indication of the availability of nutrients in the soil.
The greater concentration of salts in the soil leaves a detrimental effect on the absorption of nutrients.
Very low electrical conductivity levels indicate low available nutrients, and very high EC levels indicate nutrient excess. Those with low EC are often found in sandy soils with low organic matter levels, while high EC levels are found in high organic soil content (more clay).
Soil texture, salinity, and moisture are the soil properties that most affect EC levels.

To increase the production by 50%, we should take three important measures in the soil

After harvesting the previous crop, the crop residues should not be destroyed by fire.
After harvesting, cultivate the farm twice, so that the crop residues dissolve and provide nutrients to the plants.
Apply FYM @ 10 t/acre OR Vermicompost 2.5 t /acre + SSP @100 kg apply at the time of ploughing in the field.
Apply (1 kg of micronutrients + PSB 2 kg + KMB 2 kg + NFB 2 kg + ZnSB 4 kg + Trichoderma 2 kg) per acre on sowing time.

2. To improve the physical condition of the soil –

If the farmer having an adequate amount of water plough the field after harvesting and mix speedkampost @ 4kg/acre, after mixing provide one irrigation.
In 15-20 days, crop residues with the help of Speed kampost disintegrate well and improve soil structure.
3. For the pH balance of soil –
To control the soil pH, slow-release nutrients should be used.
Fertilizers should be used in a balanced amount of more Acid and Base content.
The soil pH rage maintains between 6.0 to 7.0 for good production of crops.
For the improvement of acidic soil, the amount of calcium carbonate should be applied according to the soil test report.
For the improvement of alkaline soil, gypsum should be applied according to the soil test report.
