Question

discuss the detailed protocol and materials required to determine the bulk density of Grass land​

Answer 1

Explanation:

${\large{\bf{\orange{Protocol \: for \: the \: Determination \: of \: Bulk \: Density \: of \: Soil}}}}$

The following procedure can be used to estimate the bulk density of soil :-

1. Identify three sample locations in the field representative of the overall field.

2. Collect soil samples from three depths using the sharp-edged cylindrical auger of 5 cm internal diameter. The auger should be driven carefully into the soil so that negligible compaction occurs. The length of soil column should at least be 10 cm.

3. Take the weight of the sample in the field.

4. Once the sample is weighed it will be oven dried at 105°C unless constant weight is achieved. It results in dry weight of the soil.

5. The bulk density is estimated by dividing the dry weight of the soil material (Wd) by the volume of soil (V) or inner volume of auger.

6. The data will be collected and entered in the format
