Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
Rangelands are commonly estimated to cover roughly what share of the earth's land?
C. 40 to 50 percent
Estimates vary with definition.
Most tropical grasses use which photosynthetic pathway, efficient in hot, sunny conditions?
C. C4
C4 grasses dominate tropical rangelands.
A site has 30% decreasers and 25% increasers, of which only 15% may be counted. Its condition score and class are:
D. 45%, fair
30 + 15 = 45, fair (26-50). 55 counts all increasers.
500 ha produce 800 kg/ha; proper use factor 0.4; a 180-day season at 12 kg/AU/day. Carrying capacity is about:
C. 74 AU
500 x 800 x 0.4 / (12 x 180) = 74. 185 ignores the use factor.
Usable forage of 120,000 kg with an AUM of 360 kg provides about:
B. 333 AUM
AUM = 120,000 / 360 = 333.
Keeping animals on the same area throughout the grazing season is:
D. Continuous grazing
Also called season-long grazing.
Using goats at specific times to reduce brush or weeds is:
B. Targeted grazing
Grazing as a vegetation tool.
Leaves of Ziziphus nummularia used as fodder in arid Rajasthan are called:
A. Pala
Ziziphus nummularia leaves are called pala.
Tannins in tree fodder, such as oak leaves, in high amounts:
A. Reduce intake and digestibility
Moderate tannins may protect protein.
A legume used to improve the quality of Indian range pastures is:
A. Stylosanthes hamata
Stylo fixes nitrogen.
