#1
Which of the following practices helps prevent soil erosion?
Planting cover crops
ExplanationPlanting cover crops provides ground cover, reducing soil erosion by wind and water.
#2
What is one benefit of incorporating compost into soil?
Improving soil structure
ExplanationCompost enhances soil structure by adding organic matter, improving water retention and nutrient availability.
#3
Which of the following is a characteristic of healthy soil?
High organic matter content
ExplanationHealthy soil contains a significant amount of organic matter, promoting fertility and biodiversity.
#4
Which of the following is a common cause of soil pollution?
Industrial waste dumping
ExplanationDumping industrial waste contaminates soil, causing pollution and harming ecosystems.
#5
Which of the following practices helps to reduce soil compaction?
Implementing no-till farming
ExplanationNo-till farming avoids plowing, reducing soil compaction and preserving soil structure.
#6
What is the primary function of soil organic matter?
Improving soil structure
ExplanationSoil organic matter enhances soil structure, promoting aeration, water retention, and nutrient availability.
#7
Which soil conservation technique involves creating a barrier to slow or redirect water flow?
Terracing
ExplanationTerracing creates steps on slopes to slow water flow, preventing soil erosion.
#8
What is the term for the ability of soil to hold and release nutrients for plant uptake?
Soil fertility
ExplanationSoil fertility is the capacity to provide essential nutrients for plant growth.
#9
Which soil organism is responsible for converting organic matter into nutrients that plants can use?
Bacteria and fungi
ExplanationBacteria and fungi play a crucial role in decomposing organic matter, releasing nutrients for plants.
#10
Which soil management practice involves planting a variety of crops together in the same field?
Polyculture
ExplanationPolyculture involves cultivating multiple crop species together, promoting biodiversity and reducing pests.
#11
Which soil conservation technique involves rotating crops on a regular basis?
Crop rotation
ExplanationCrop rotation helps break pest cycles, improves soil health, and enhances nutrient availability.
#12
Which soil amendment helps to increase soil pH and add essential nutrients like calcium and magnesium?
Gypsum
ExplanationGypsum is used to improve soil structure, increase pH, and supply essential nutrients.
#13
Which of the following factors can contribute to soil degradation?
Urbanization
ExplanationUrbanization leads to soil compaction, loss of organic matter, and reduced fertility.
#14
Which of the following is NOT a component of soil texture?
Humus
ExplanationHumus is organic matter; soil texture components include sand, silt, and clay.
#15
Which of the following soil organisms is responsible for improving soil structure by creating tunnels?
Earthworms
ExplanationEarthworms burrow, creating tunnels that enhance soil structure, aeration, and drainage.
