Katen [24]3 years ago

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.

Plate tectonics and evolution, which are held with a high degree of confidence because of rigorous testing and verification, are
forsale [732]

Answer:

<em>The correct option is theories. </em>

Explanation:

A scientific theory is a detailed explanation of natural researches which are supported through evidence. Scientific theories can be changed if other evidence are made which support another theory. Hence, scientific theories can change. The concepts of plate tectonics and evolution change overtime whenever new pieces of evidence are discovered. Hence, they are scientific theories.

Other options such as hypotheses are not correct because a hypothesis is just a tentative statement which can either be proved to be correct or wrong. Observations are not made on evidences hence the option observations is also not correct.

Rank the following foods from lowest (1) to highest (4) glycemic index. carrots baked potatokidney beans white rice lowest highe
svetlana [45]

Answer:

Explanation:

  To rank these foods in the amount of sugars, I will first explain the index I will use, which is called the glycemic index. This index is based on the classification of carbohydrate-rich foods according to how they affect blood glucose levels, popularly known as blood sugar.

  The higher the glycemic index, the easier the food is digested and absorbed in the gut, increasing the glycemia. Thus, the foods were divided into 3 categories:

Low IG: 55 or less

Average IG: 56 - 69

High IG: 70 or more

 Based on this, the lowest to highest glycemic level food ranks as follows: beans, liver, carrots, white rice and baked potatoes.

What is the best description of the paths of S waves and P waves?
Anastaziya [24]

Answer:

S waves travel through solids or very dense, glassy liquids. P waves travel through solids, liquids, and gasses.

Explanation:

S-waves and P-waves are both body waves that moves through a substance. They are different from surface waves that moves on the surface. These surface waves are love and Rayleigh waves.

 The body P-waves and S-waves are often differentiated by the materials they propagate through. P-waves are primary waves and they pass through any earth materials. They can be propagated through solids, liquids and gases. This is because they are longitudinal waves.

S-waves are shear waves and they cannot pass through liquids and gases. These materials do no shear.
