Answer:
The total number of cubes required is the product of the dimensions in cube-lengths: 3×4×2 = 24 cubes
Answer:
B. Alert the body to the presence of insects
Recommended rates of potash for grazed grass are 60kg/ha and 30kg/ha of K2O for soil index 0 and 1 respectively. For soils with higher soil fertility levels no potash required.
Very large quantities of potash are removed in grass silage which must be replaced to maintain soil fertility and yield potential. The following is guide to typical potash offtakes from multi-cut silage systems.Low soil magnesium levels will affect grass yield as well as mineral balance in the animal. Apply 50-100 kg/ha MgO every three to four years at Mg index 0. Yield response is less certain at index 1 but magnesium application is justified in terms of insurance for grass yield and mineral balance for the animal, to maintain a soil magnesium index of 2.
Where lime is required and Mg levels are 0 and 1, use magnesian limestone as the most cost effective magnesium source. Where pH is satisfactory, specific magnesium fertilisers (see table below) should be used for soil improvement. Use water soluble forms of magnesium where rapid plant uptake is required.
Answer:
A process known as subduction
Explanation:
A batholith has an irregular shape with side walls that incline steeply against the host rock. Most batholiths intrude across mountain folds and are elongated along the dominant axis of the range; faulting and contact metamorphism of the enveloping rock near the batholith is also observed.
