Question
Due to heavy rain and floods, soil from the streets is collected as sediments in agricultural land.Which of the following scenarios is more likely to occur?a.Increase pestsb.Decrease crop productionc.Decrease pestsd.Increase crop production
Solution
The most likely scenario to occur when soil from the streets is collected as sediments in agricultural land due to heavy rain and floods is b. Decrease crop production.
Here's why:
-
Introduction of foreign soil: The soil from the streets is likely to be polluted with various substances like oil, garbage, and other urban waste. When this soil is introduced to agricultural land, it can contaminate the existing soil.
-
Soil composition and structure: The composition and structure of the soil are crucial for crop growth. The introduction of foreign soil can disrupt the balance of nutrients in the agricultural soil, affecting its fertility.
-
Waterlogging: Heavy rain and floods can lead to waterlogging in the agricultural land. Waterlogged soil can lead to root rot and other diseases, which can decrease crop production.
-
Displacement of topsoil: The topsoil, which is rich in nutrients, can be displaced by the heavy rain and floods. This can lead to a decrease in soil fertility, affecting crop production.
Therefore, while pests may also be affected, the most direct and significant impact would be a decrease in crop production.
