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.
Just as you "step" outside of our Earths ozone layer everything there it will kill you if not for the special suits! Radiation, space vaccum, pressure, temperature, etc is not human species friendly! That's why we need The ozone layer, without which we would not survive more than a few days on this planet!
Answer:
sun is bigger than earth is 13.9 cm
Explanation:
given data
radius of sun = 700,000 km
radius of earth = 6500 km
to find out
how big is the sun
solution
we know here
scale 1 to 10 billion is
scale = 
so here
we know that scaled diameter = actual diameter × scale .................1
so for earth
scaled diameter of earth = 2 × 6500 ×
scaled diameter of earth = 1.3 × 
and
scaled diameter of sun = 2 × 700,000 ×
scaled diameter of sun = 1.4 × 
so
sun is bigger than earth is 1.4 × - 1.3 ×
sun is bigger than earth is 0.000139 = 13.9 cm
Answer:
mark brainliest
Explanation:
Most fossil fuels, such as oil, natural gas, and coal are considered nonrenewable resources, as their use is not sustainable because their formation takes billions of years.
