Overview:
The results of our test show that the potting soil is on par with the ARHS soil in
every way besides humus. However, when the soil was moist, it appeared that the potting mix soil
contained more humus, thereby making me conclude that there was an error. Also, Our group (the
one responsible for Potassium) used the wrong test tube to measure the potassium levels in the
ARHS soil. However, the potassium levels in the ARHS soil are, without a doubt, still lower than the
potting soil's.
Soil quality analysis:
In terms of agriculture, the potting soil is of equal and oftentimes greater quality and fertility
than the ARHS soil in most areas besides phosphorus, where it has higher than optimal
levels. First, phosphorus levels in the ARHS soil are slightly less ideal than the potting soil's. For
example, phosphorus levels in the ARHS soil and potting soil are 37.5 ppm and 25 ppm respectably.
At first it may see that the ARHS soil has higher phosphorus levels than the potting soil, and indeed
it does, however the method in which we measure soil differs fo...
Possible errors include leaving in the test strips for too long, draining too much water into the aquatic chamber (overfilling/watering), and inverting the tubes for a shorter amount of time than required. Although there are many possible human errors that could be committed in this lab, it is important to note that the tools used for water testing could be expired and could therefore not work as well at detecting the proper levels for dissolved oxygen, pH, and nitrate.
Thanks to an amazing discovery the Americans started to do fertilizes with crushed bones. Justus von Liebig refined the technique finding that adding sulphuric acid to the crushed bones the fertilizers was working better. When phosphate rock was not discovered, most probably, crushed bones were used to acidulate to produce SSP in the mid 1840s.An interesting account of the discoveries and development of phosphate industry has been provided by Hall (7) exactly a century ago. Historically, there were four main players in the development of phosphate fertilizers. They were Liebig of Germany, Lawes and Henslow of U.K. and Murray of Ireland
The differences seen in the soil may be due to addition of carbon/ nitrogen which can change and alter the C:N ratio. The greater C:N ratio the more extracellular polymers are released which help hold the aggregates together and better its stability. The lower the C:N ratio the worse the aggregate stability and the faster the aggregate will crumble away as can be seen in both a slaking test and the alfalfa treatment.
This type of peanut requires a light-colored, light texture, good drainage, and moderately low amounts of organic matter from the soil that it is to be planted in. Soil, such as this, is preferred because of its loose and friable qualities; which permits a better penetration of roots and pegs, better filtration of rainfall, and easier harvesting. The organic matter within the soil should be maintained at a level of one to two percent percent to improve its water-holding capacity and supply pant nutrients. In addition, this type of peanut grows better in slightly acidic soils with a pH level of 6.0 to 6.5. The spanish peanut also responds well to residual soil fertility, which is soil from previous crops in rotation.
The study is to determine which of the soil compaction method is most effective way in terms of which method can compact the soil particles closer by referring to the difference of the sand volume in the mould before and after the compaction test done.
Phosphorus stimulates root growth, helps the plant set buds and flowers, improves vitality and increases seed size. It does this by helping transfer energy from one part of the plant to another. To absorb phosphorus, most plants require a soil pH of 6.5 to 6.8. Organic matter and the activity of soil organisms also increase the availability of phosphorus.
This project is important because different types of soil change the growth of plants, so with doing this experiment I could find which type is best. In the past, I have struggled to find a good soil where my plants grow fast. Finding which type of soil is best could help farmers and normal adults/students, including me, to grow their plants faster. This is important because growing plants faster can mean getting food faster.
value of the water has any effect on how much water each type of soil

Healthy soil is important because people use it in their everyday lives, it affects us in everything that we do. For example: soil makes up the outermost layer of our plant, soil supports organisms that are essential for a healthy environment, healthy soils are essential for a sustainable environment, our landscape is sustained by soil, we use soil to flourish our food and it helps to keep our drinking water clean, and soil plays a vital role in maintaining the balance of gases in the air that we breathe, trees grow in it, which produce oxygen, and soil is formed from rocks and decaying animals, so the dead animals don’t go to waste. Healthy soil contains 45 percent minerals, 25 percent water, 25 percent oxygen, and 5 percent organic matter. This percentage helps with the soil in the process of keeping plants healthy for organisms to stay zoetic. In the soil there are scads of life dwelling among the soil.
In the last few years farmers and nursery men are much concerned about the potting media as it play an important role in plant production. There is a continuing interest by using various agricultural by-products as an organic nutrient source for plants due to increasing awareness of environment-related issues, as well as the need to dispose off and use rising amounts of waste (Grigatti, 2008).
Saline soil is also vulnerable to erosion due to the death of vegetation that held the soil together. Soil that is eroded can ‘pollute’ water too.
You can buy the good soil online or at a store. But the disadvantages are the pets, because many kinds of

Our reality today, is confronting a colossal issue, the issue of soil disintegration. Not just is it an intense issue, it has likewise turned out to be generally spread that it requests our quick activity. Soil disintegration is created and influenced by a few variables; notwithstanding, it can be minimized by a few simple activities which one can actualize day by day.
