Problems of mechanization - SS1 Agriculture Past Questions and Answers - page 2
The lack of technical expertise in operating and maintaining machinery is a challenge primarily faced by:
Large-scale farmers
Small-scale farmers
Organic farmers
) Hydroponic farmers
Which of the following is NOT a form of environmental pollution associated with mechanized agriculture?
Air pollution
Soil pollution
Noise pollution
Light pollution
Mechanization can lead to economic limitations for farmers primarily due to:
Reduced labor requirements
Increased crop yields
High maintenance costs
Improved soil health
Soil compaction caused by heavy machinery can reduce:
Crop yields
Environmental pollution
Soil fertility
Timeliness of operations
What is one potential consequence of soil compaction caused by heavy machinery in mechanized agriculture?
Soil compaction can reduce aeration, water infiltration, and root penetration, which can harm crop yields and long-term soil health.
How does mechanization contribute to environmental pollution in agriculture?
Mechanization can lead to environmental pollution through the emissions of pollutants from diesel-powered machinery and the use of chemical fertilizers and pesticides, which can contaminate soil and water.
What economic challenges can farmers face when considering mechanization in agriculture?
Farmers may encounter economic limitations, including the significant upfront cost of machinery, ongoing expenses for maintenance and fuel, which can be particularly burdensome for small-scale or resource-limited farmers.
Why is technical knowledge and expertise important for farmers when using agricultural machinery?
Technical knowledge is crucial for the safe and effective operation, maintenance, and repair of agricultural machinery. Without the necessary skills, farmers may struggle to adopt mechanized farming practices.
What are some challenges faced by small-scale farmers regarding the adoption of mechanization?
Small land holdings can pose a significant challenge for small-scale farmers when adopting mechanization, as many types of farm machinery are designed for larger-scale operations and may not be suitable for small, irregular plots.
How does soil compaction affect the productivity of agricultural land?
Soil compaction reduces the pore space in the soil, hindering the movement of air, water, and nutrients. This restriction can result in reduced productivity by impeding root growth and plant access to essential resources.
