Which is a incorrect match in the following
A. Soil bulk density : Hydrometer
B. Particle size analysis of soil : Pycnometer
C. Soil moisture retention : Permeameter
D. Soil moisture estimation : Potometer
Answer: Option D
Solution(By Examveda Team)
A hydrometer method is used to determine the particle size distribution of fine-grained soils passing 75 µ sieve. The hydrometer measures the specific gravity of the soil suspension at the center of its bulb. It also measures soil bulk density.A pycnometer is a small glass bottle of known volume for determining the relative density of liquids and solids by weighing. It helps in Particle analysis of soil.
A permeameter is a tool to measure soil moisture retention, saturated permeability, or K-factor of the soil samples.
A potometer is designed to measure water uptake in a leafy shoot. It cannot estimate soil moisture.
