10 practice questions, worked

Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.

1 · Saline and alkaline soils · medium

Gypsum is added to sodic soils because it supplies:

  1. Nitrogen for growth
  2. Sodium to bind clay
  3. Potassium for roots
  4. Calcium for sodium
Answer and working

D. Calcium for sodium

Calcium displaces exchangeable sodium.

2 · Saline and alkaline soils · medium

The tree species most tolerant of highly sodic soils, though invasive, is:

  1. Tectona grandis
  2. Shorea robusta
  3. Prosopis juliflora
  4. Dalbergia latifolia
Answer and working

C. Prosopis juliflora

Widely planted on sodic land.

3 · Coastal sands and sand-dune fixation · medium

Brushwood fences for dune stabilisation are placed:

  1. Parallel to the wind direction
  2. Only on the dune crest
  3. Below the high tide mark
  4. Across the direction of the wind
Answer and working

D. Across the direction of the wind

They trap moving sand.

4 · Lateritic, rocky and dry sites · medium

A crescent-shaped water harvesting basin opening uphill is called a:

  1. Half-moon
  2. Gabion
  3. Check dam
  4. Auger hole
Answer and working

A. Half-moon

Half-moon basins open uphill to catch runoff.

5 · Ravines and gullies · medium

Check dams in gullies are spaced so that the top of one dam is level with:

  1. The top of the gully bank
  2. The bed of the main river
  3. Toe of the next dam
  4. The tableland surface
Answer and working

C. Toe of the next dam

Head-to-toe spacing stabilises the whole gully bed.

6 · Wetlands and waterlogged sites · medium

On waterlogged sites, seedlings are often planted:

  1. In deep pits below water
  2. On raised mounds or ridges
  3. In sealed plastic tubes
  4. Only in the rainy season peak
Answer and working

B. On raised mounds or ridges

Above the water table.

7 · Wetlands and waterlogged sites · medium

An aquatic invasive targeted in wetland restoration is:

  1. Water hyacinth
  2. Lotus
  3. Water lily
  4. Wild rice
Answer and working

A. Water hyacinth

Eichhornia crassipes.

8 · Invasive plant species and their control · easy

The beetle Zygogramma bicolorata is a biological control agent of:

  1. Lantana
  2. Parthenium
  3. Water hyacinth
  4. Prosopis
Answer and working

B. Parthenium

Mexican beetle released in India.

9 · Assisted natural regeneration and framework-species methods · easy

Assisted natural regeneration mainly works by:

  1. Planting only exotic species
  2. Clearing all vegetation
  3. Protecting regeneration
  4. Draining the site
Answer and working

C. Protecting regeneration

It accelerates succession.

10 · Assisted natural regeneration and framework-species methods · hard

Framework species are planted about 1.8 m apart in a square grid. Trees per hectare are about:

  1. 5,556
  2. 3,086
  3. 1,800
  4. 10,000
Answer and working

B. 3,086

10,000 / 1.8^2 = 3,086. 5,556 divides by 1.8 only once.
