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.
The correct answer to this open question is the following.
The simple ways you can do or contribute in order to lessen the effect or to fight the natural calamities are the following.
First, Filipino people have to know that mother Earth is a conscious being, like. us. The earth has inner processes to renew itself or to clean itself that have happened since the Earth exists: these are hurricanes, typhoons, tornados, earthquakes, deluges, rains, volcanic explosions, and climate changes.
People have to be aware of this and be prepared. The best form is to have a plan. A prevention plan and an action plan. They have to invest in infrastructure to control and diminish the consequences of natural phenomena. The government has to develop the educational and informative to let people know what to do in the case of these events. Their rescue programs and services have to be well prepared with the proper equipment to act swiftly.
Answer:
- It is also called orographic rainfall
- It consists of two sides of a mountain each having its name
- The side with the rainfall is called windward side and the side without rainfall is called lee ward side
The reason why there is rain on only one side is because when clouds move from one side of the mountain to the other side, the cloud is very heavy, so it showers off on the side of the mountain which it is on (windward side) and very less water is left to shower off on the other side (leeward side)
If my answer helped, kindly mark me as the brainliest!!
Thank You!!
Answer:
False
Explanation:
The correct answer is:
Maps that show population density are Thematic maps.
Thematic map is basically used to represent particular themes for particular geographical area. For example, population variation, temperature variation or population density, average annual income, rainfall distribution etc. Thematic map is also called special purpose and this can be quantitative or qualitative.
Physical maps is option is not true because physical maps are used to depict topography or natural landscapes or geographical features of an area such as mountains, deserts, bodies of water etc.
