Introduction

Kenmaru Suedomi, Juan Jose Montoya, H Block Soil Testing Lab Experiments Observation of the soil area (Soil A and Soil B) 1. Some plants are seen nearby the soil 2. The soil is not wet but not dry 3. Most of plants are glass 4. Some organic matters can be seen (flowers and insects) 5. Greenish color 6. Some Brownish color 7. Plants are growing but not that much Soil Texture by feel (Soil A and Soil B) 1. When the soil remain in a ball and is squeezed, it forms a thin ribbon which breaks readily, barely sustaining its own weight 2. Not very smooth 3. Not very sandy 4. More like a clay 5. The soil has some sand but not a lot By following the paper ?Guide to Texture by feel?, it shows that Soil A is clay loam and Soil B is clay. ...read more.

% Clay = 11.25 / 43.16 * 100 = 26 % Silt = 12.90 / 43.16 * 100 = 30 % Sand = 19.01 / 43.16 * 100 = 44 By using textural triangle I could see that both soils are Clay Loam % of organic matter/humus content = Loss in mass after heating / mass of dry soil *100 Masses of organic matter and soil, Percentage of organic content (+/- 0.01g) Empty dry crucible Dry Soil and crucible Soil and crucible 1st heating Soil and crucible 2nd heating Soil and crucible 3rd heating Mass of Organic Matter Mass of dry soil Percent of organic matter in the soil % Soil A 13.30 23.66 23.01 21.54 20.16 3.50 10.30 34% Soil B 13.30 24.76 24.21 23.47 21.65 3.11 11.46 27% Sample Calculation: 1. Mass of organic matter = 23.66 ? 20.16 = 3.50 Mass of dry soil = 23.66 ? 13.30 = 10.30 % of organic matter in the soil = 3.50 / ...read more.

Conclusion

However, we were able to find the soil texture by calculating the percentage of each clay, silt, and sand soils. We used a textural triangle to find the soil texture so we could get the better data. When calculating organic matter and water of the Clay Loam soil, we could find some descriptions about this soil. As you can see the data Soil, 34% of the Soil A (Clay Loam) is water. This is quite high, means that this soil contains some water. Therefore, some plants could live in this Clay Loam soil. Also, we learned that plants and organic matters can live in Clay Loam because when you look at the pH and Nitrogen data you see that the pH was neutral and there were enough nitrogen for plants to grow. In conclusion, you can see if the soils are good for plants by looking at pH, Nitrogen, % of organic matter and water. In our case, we could find out that the Clay Loam is a soil that is good for plants and grasses. ...read more.
