Question

(B) For the production of paddy the pH level of soil should be between 5 to 8, why?​

Answer 1

Explanation:

Fertile riverine alluvial soil is best for rice cultivation. Although pH of rice soil become neutral, it should be 5 - 8. Because, if soil is more acidic or more alkaline, it will need more time to become neutral. ... Furthermore, flat lands are better for rice farming to allow balanced water distribution.

Answer 2

For the production of paddy, the pH level of soil should be between 5 to 8, because for the following reasons.

• A well-maintained soil pH will maintain the soil resources and will maximize crop and pasture production.
• A pH between 5 to 8 will be a suitable condition for the soil as it avoids production losses.
• Soil pH regulates plant nutrient availability by controlling the chemical forms of the different nutrients and also influences their chemical reactions.
• Soil nutrients leach out when the pH of soil exceeds the suitable condition.
• pH below 5 becomes toxic to plant growth.
