Soil and Soil Formation - JSS2 Agricultural science Past Questions and Answers - page 1
What is the primary focus of the week on soil and soil formation?
Introduction to agricultural tools
Overview of animal husbandry practices
Understanding soil science, properties of soil, soil formation, and soil classification
Ignoring the importance of sustainable practices in agriculture
Why is an introduction to soil science crucial in agriculture?
To neglect the importance of soil in crop production
To understand the properties and characteristics of soil for informed agricultural practices
To discourage the use of soil classification systems
To avoid considering the impact of technology on soil formation
What factors contribute to soil formation processes?
Only human activities
Parent material, climate, topography, organisms, and time
Exclusively geological processes
Ignoring the role of living organisms in soil formation
How do soil properties impact agricultural productivity?
They have no influence on crop growth
Soil properties influence nutrient availability, water retention, and root development
Soil properties only affect animal husbandry
They discourage sustainable farming practices
What is the primary purpose of soil classification in agriculture?
To limit the understanding of soil diversity
To discourage sustainable farming practices
To facilitate communication about soils and guide land use decisions
To neglect the importance of soil in crop production
Which factor is not typically considered in soil classification?
Soil texture
Parent material
Crop yield
Organic matter content
How does climate contribute to soil formation?
It has no impact on soil characteristics
Through temperature and precipitation affecting weathering processes
Climate only influences animal husbandry practices
By discouraging sustainable farming practices
What is the significance of parent material in soil formation?
It does not play a role in soil characteristics
Parent material provides the basis for soil development, influencing mineral content
Parent material only affects the topography of soil
It discourages sustainable farming practices
Which of the following is a crucial aspect of soil that influences plant growth?
Colour of the soil
Soil classification
Soil temperature
Soil classification only
How do living organisms contribute to soil formation?
They have no impact on soil characteristics
Through their activities, such as decomposition and organic matter accumulation
Living organisms only affect animal husbandry practices
They discourage sustainable farming practices
