Question

20 mark for review which of the following would be most helpful to determine the soil texture of a sample? a a ph meter and conductivity meter b a soil core kit and a seismograph c a density gradient tube and a soil triangle d a quadrat and a transect line

Explanation:

A density - gradient tube can separate soil particles by size, and a soil triangle is used to classify soil texture based on the percentages of sand, silt, and clay. A pH meter and conductivity meter measure soil pH and conductivity respectively, not texture. A soil core kit is for sampling soil, and a seismograph measures seismic activity. A quadrat and transect line are for ecological sampling, not soil texture determination.

Answer:

C. A density gradient tube and a soil triangle
