3rd. A study of the ecology of the sources of growth
3.1 Properties of the water resource growth paddle him. (Table 1)
- water temperature. Ranged from 24.0 to 24.5 degrees Celsius, average for the year 24.1 degree Celsius air temperature Ranged from 24.6 to 28.0 degrees Celsius, average at 26.1 degrees Celsius
- the contrast is between 8,100-49,500 lux averages around 25,650 lux
- turbidity of the water. Ranged from 3.57 to 21.23 ftu average in the year 80 ftu
- the pH. Ranged from 6.32 to 6.95 on average in the year 6.59
- the amount of dissolved oxygen. Ranged from 5.4 to 7.4 mg / L, the average at 6.5 mg / l
.- The volume of free carbon dioxide in water Ranged from 4.0-7.0 mg / l average in the year
5.25 mg / l
- alkalinity is between 24-52 mg / L, the average at 36.5. mg / l
- hardness is between 22-51 mg / lThe average at 33.75 mg / l
- ammonia - nitrogen. Ranged 0.0280 to 0.0437 mg / l, the average at 0.0380 mg / l
- nitrite - nitrogen. Ranged 0.0029 to 0.0064 mg / l, the average at 0.0049 mg / l
.- Nitrate - nitrogen. Ranged 0.0235 to 0.0478 mg / l, the average at 0.0384 mg / l
- orthophosphate ranged. 0.0134 to 0.0334 mg / l, the average at 0.0241 mg / l
3.Two properties of the soil in growing source of his paddle. (Appendix Table 2)
- pH is alkaline. Ranged from 6.05 to 6.58 on average in the past year, 6.26
.- By comparing the composition of soil organic matter, organic matter percent, the ratio is between 0.44 to 1.37 percent and averaging 0.84 percent for the year
- Phosphorus is helpful. Ranged from 5.49 to 23.43 mg / kgThe average at 13.31 mg / kg
- potassium ranged from 31.0 to 149.46 mg / kg, the average at 93.09 mg / kg
- ratio of soil particles. Found the soil is a sandy soil (sandy loam) and
clay and sandy (sandy clay loam)
