2; germination percentage of seeds is 90; purity percentage of seeds is 90; test weight of rice seed is 25 g; damaged
seedlings during uprooting from the nursery is 20% of the uprooted seedlings.
If the volume of soil solids is denoted as Vs and the volume of soil pores as Vf, which of the relationships between void ratio
(e) and porosity (f) is correct
Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : The medium-textured soils are often more susceptible to soil erosion
Reason (R) : Silt and very fine sand content in soil increases the erodibility of soil
In light of the above statements, choose the correct answer from the options given below.
Which type of crust is found in sodic soils?
If, bulk density (pb) and particle density (ps) of a soil are 1.5 Mg mand 2.5 Mg m®, respectively, then porosity (%) will be
Match List-I with List-II:
Choose the correct answer from the options given below:
Given below are two statements
Statement (I) : Uniformity coefficient in soil refers to the ratio of dgo to dro,
Statement (II) : A well graded loamy soil shall has lower uniformity coefficient than sand
In light of the above statements, choose the most appropriate answer from the options given below.
Assumptions and Limitations of Stokes’ Law
(A) . Particles must be spherical, smooth and rigid. But, soil colloidal particles are plateshaped and fall slower than spherical
particles of the same mass.
(B) . Size of particles must be large compared to the size of molecules of the liquid, so
that the medium can be considered homogeneous, i.e. no Brownian movement occurs.
(C) . Fall must be unhindered. Particles falling very near the wall of the vessel (0.1 mm.
distance) are slowed down in their descent. Many fast falling particles may drag finer
particles down along with them (concentration up to 3% solids)
(D) . Particles must be of uniform density and the suspension must be still without any
turbulence
Choose the correct answer from the options given below:
Match List-I with List-II:
Choose the correct answer from the options given below:
If the volume fractions of water content, mineral and organic constituents in a soil are 0.25, 0.50 and 0.25, what will be the
volumetric heat capacity of soil in cal/em? ?
