Test: |touched |the |soil |to |feel |the |different |textures
2. |Shifting |Method: |put |the |soil |through |multiple |layers |that |got |finer |as |the |layers |went |down
|
3. |Hydrometer: |placed |in |a |glass |column |to |measure |the |density |used |to |calculate |sand, |silt, |
clay
Name |a |physical, |chemical |and |biological |property |of |soil |we |will |study |in |this |course |- |
CORRECT |ANSWER✔✔-1. |Physical: |texture, |density
2. |Chemical: |pH, |CEC, |nutrients
3. |Biological: |earthworms, |microbial |biomass
