DANCING BUTTERFLY PEA WEEK 2 REPORT

    Our soil textural triangle

The deposition of soil into three layers

Calculation for the soil textural triangle

      
          

The result showed the soil is loamy soil

                               

Our lab report

         We weight the dried soil that we dried outside of laboratory for a one week. The weight was reduced from 500grams to 402.29 grams so about 97.71 grams weighed is loss. Then we weighed about 20 grams of soil to conduct macronutrient analysis which are Phosphate (PO₄^3-), Sulphate (SO₄^2-) and Nitrate (NO₃-). We add about 50ml of distilled water together with the soil sample and mix the solution for 20 minutes by using magnetic stirrer. We left the mixture for 10 minutes. Then we filter the mixture by using 0.45 µm membrane filter paper using vacuum pump. Then we Store in HDPE bottles for macronutrient analysis using the HACH kit.

     Here are the result of macronutrient analysis       

   

     Reading of Phosphate (PO₄^3-) (490 P React. PV)

1st reading	3.92 mg/L
2nd reading	3.92 mg/l
3rd reading	3.90 mg/L
Average reading	3.91 mg/L

     Reading of Sulfate (SO₄^2-) (680 Sulfate)

1st reading	42 mg/L
2nd reading	42 mg/L
3rd reading	42 mg/L
Average reading	42 mg/L

 Reading of Nitrate (NO₃-) (355 N Nitrate HR PP)

1st reading	7.20 mg/L
2nd reading	7.20 mg/L
3rd reading	7.30 mg/L
Average reading	7.23 mg/L
