Assertion :Amount of leaching is determined by climate, soil type, and the type and quantity of nutrients present in the soil in the soluble form Reason: The greater the leaching potential of a fertilizer product, greater care is necessary when the material is used on sandy soil as ground water contamination is more likely.
B is the correct option both assertion and reason are correct but reason is not correct for the assertion.
Amount of leaching is determined by climate, soil type, and the type and quantity of nutrients present in the soil in the soluble form
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
