Potash and magnesium are examples of?
Katen [24]
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.

3) When the temperature of a blackbody increases from 900 K to 2300 K, by what factor does the total power of the electromagneti
LekaFEV [45]

Answer:

The electromagnetic radiation per-unit- area increase by 42.65 times.

Explanation:

The radiation per-unit- area (P) is directly proportional to the fourth power of the temperature. Thus,

P ∝ T⁴

For, when the temperature is raised from T₀ to T₁ , the radiation per-unit- area is related to as:

\frac {P_1}{P_0}=\frac {T_1^4}{T_0^4}

T₀ =  900 K

T₁ = 2300 K

\frac {P_1}{P_0}=\frac {2300^4}{900^4}

So,

<u>P₁ = 42.65 P₀</u>

<u>The electromagnetic radiation per-unit- area increase by 42.65 times.</u>
