Question 5

Kerala's mid-highlands are characterized by specific soil types that support its prominent plantation economy. Which soil type, formed under conditions of high temperature and heavy rainfall, is known for its acidic nature, low inherent fertility (due to intense leaching), and suitability for crops like rubber, tea, and cashew after proper management?

Accepted Answer

B. Laterite soils — Laterite soils are predominantly found in the mid-highlands of Kerala, formed through intense leaching of silica and other bases under tropical conditions of high rainfall and temperature. This process leaves behind oxides of iron and aluminum, making the soil acidic and low in inherent fertility. Despite this, with proper management (liming, fertilization), these soils are well-suited for plantation crops like rubber, tea, and cashew. Alluvial soils are found in river valleys and coastal plains, black soils are rare in Kerala, and red sandy soils, while present, do not fit the description of

Question 7

Kerala's tropical monsoon climate, characterized by high temperatures and heavy rainfall, significantly contributes to the widespread formation of laterite soils, especially in the midlands and highlands. Considering the typical characteristics of laterite soils, which agricultural approach is most appropriate for sustainable cultivation in these regions?

Accepted Answer

B. Plantation agriculture involving crops like rubber, cashew, and various spices, often coupled with contour farming and organic matter enrichment. — Laterite soils, common in Kerala's midlands and highlands, are typically acidic, porous, and nutrient-poor due to heavy leaching. However, they are well-suited for plantation crops like rubber, cashew, and spices which can tolerate these conditions. Sustainable practices like contour farming prevent soil erosion, and enriching with organic matter improves fertility, making option B the most appropriate.

Answer

A. Intensive paddy cultivation requiring constant waterlogging and high nutrient input in large, flat fields.

Answer

C. Large-scale cultivation of annual food grains such as wheat and maize using conventional deep plowing methods.

Answer

D. Extensive horticulture of temperate fruits like apples and pears, which thrive in deep, fertile loamy soils.
