How does crop rotation contribute to improving soil fertility and.
Question
- A. Reduces soil erosion
- B. Increases soil biodiversity
- C. Improves soil fertility and pest management
- D. All of the above
View Answer
Correct Answer ( C )
Crop rotation involves planting different crops in a sequence on the same land , which significantly improves soil fertility by diversifying nutrient uptake – for example – nitrogen in the soil, benefiting subsequent crops . Rotating crops also breaks pest and disease cycles – reducing the need for chemical pesticides – a well-planned rotation minimizes nutrient depletion and pest build-up in the soil . Crop rotation can increase soil structure , improve water infiltration and reduce weed pressure
Explain the different types of agricultural tillage practices and their.
Question
- A. Plowing, harrowing, and subsoiling
- B. No-till, conservation tillage, and reduced tillage
- C. All of the above
- D. Only plowing and harrowing
View Answer
Correct Answer ( C )
Agricultural tillage involves manipulating soil structure for planting . Conventional tillage, such as plowing and disking, involves significant soil disturbance initially, improving aeration and water infiltration , but can lead to soil erosion, reduced organic matter , and compaction over time . Conservation tillage methods, like no-till farming, minimize soil disturbance, preserving soil structure, organic matter and beneficial soil organisms . Reduced tillage , a compromise, involves less intensive plowing or disk
What are the common methods used for soil testing to.
Question
- A. Visual inspection and smell test
- B. Using a metal detector to sense nutrient levels
- C. Laboratory analysis and field test kits
- D. Comparing soil color to a chart
View Answer
Correct Answer ( C )
The soil testing is crucial to determining nutrient levels and guiding fertilizer application . Common methods include laboratory analysis, where soil samples are analyzed for various nutrients (N, P, K, etc. ) using chemical or spectroscopic techniques . Field testing methods, while less precise, offer quick estimates using soil test kits that measure pH and some key nutrients . The choice of method depends on the resources available, the level of accuracy needed and the scale of the operation . Accurate soil testing informs precise fertilizer
