With reference to agricultural soils, consider the following statements: 1) A high content of organic matter in soil drastically reduces its water holding capacity. 2) Soil does not play any role in the sulphur cycle. 3) Irrigation over a period of time can contribute to the salinization of some agricultural lands. Which of the statements given above is/are correct?

Correct Answer: 3 only. ● Soil texture and organic matter are the key components that determine soil water holding capacity. Each 1 percent increase in soil organic matter helps soil hold 20,000 gallons more water per acre. ● Sulphur is one of three nutrients that are cycled between the soil, plant matter and the atmosphere. ● Salinization is a major problem associated with irrigation because deposits of salts build up in the soil and can reach levels that are harmful to crops
