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 and Explanation:
CE stands for Common Era which is a modern replacement for AD( Anno Domini).
Therefore, 2020 c.e is equal to 2020 A.D. (Anno Domini )
In the Chinese year(calendar) :
2020 c.e corresponds to 4717 Chinese Year
In the Islamic year :
2020 c.e corresponds to 1441 Islamic year
In the Jewish year:
2020 c.e corresponds to 5780 Jewish year
Answer:
the crust because all of the cores are inside the earth towards the middle but the crust is the very earth we walk
Explanation:
It is Egypt. The river Nile runs through the city and Tahrir square (a big museum full of Egyptian artefacts) is right in the centre of the city.
Answer:
The Nile is composed of two tributaries: the White Nile and the Blue Nile. The White Nile, which is the longer of the two, begins at Lake Victoria in Tanzania and flows north until it reaches Khartoum, Sudan, where it converges with the Blue Nile.
