Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
Juglone, a classic allelochemical, is produced by:
A. Black walnut
Juglans nigra produces juglone.
Mimosine, which can inhibit plants and harm livestock, is found in:
A. Leucaena leucocephala
Leucaena contains mimosine.
Trees on farms cannot create which of these nutrients, only recycle them?
C. Phosphorus
Mineral nutrients like P are only redistributed.
Decomposition of litter in the field is usually measured with:
A. Litterbags
Mesh bags retrieved over time.
Cutting the main stem at 2 to 3 m and harvesting the regrowth repeatedly is:
D. Pollarding
Pollarding keeps regrowth above browsing height.
Removing branches for fodder without cutting the main stem is called:
A. Lopping
Common for Grewia, Celtis and khejri.
A tree-crop system gives 75% of sole crop yield and 50% of sole tree yield. The LER is:
A. 1.25
LER = 0.75 + 0.50 = 1.25; above 1 means a land-use advantage.
An agroforestry plot gives 2.4 t/ha of wheat (sole wheat 4.0 t/ha) and timber equal to 70% of a sole plantation. The LER is:
A. 1.30
2.4/4.0 = 0.60; 0.60 + 0.70 = 1.30.
The IPCC default carbon fraction of dry wood biomass is:
B. 0.47
0.47; 0.5 is also used.
Future agroforestry costs and benefits are converted to present values by:
C. Discounting
PV = C / (1 + r)^t brings future values to the present.
