The relative proportion of soil separates in a particular soil is called:

Correct option is B

Correct Answer: (B) Soil texture
Explanation:
→ Soil texture refers to the relative proportion of different soil particles—sand, silt, and clay—in a soil sample.
→ It determines the soil’s physical properties, such as water retention, aeration, permeability, and fertility.
→ Soil texture is a permanent characteristic of soil and does not change with tillage or management practices.
→ Different soil textures, such as sandy, loamy, and clayey soils, influence plant growth and suitability for agriculture.
Information Booster:
→ Soil texture is determined by proportions of sand, silt, and clay.
→ Affects water retention and drainage; sandy soils drain fast, clayey soils retain water.
→ Influences soil aeration, root penetration, and nutrient availability.
→ Loamy soils with balanced texture are ideal for agriculture.
→ Texture classification helps in soil management and crop selection.
→ Measured through soil particle analysis in laboratories.
→ Permanent property, unlike soil structure, which can change over time.
Additional Information (Other Options):
Option (A) Soil structure – Arrangement of soil particles into aggregates, affects aeration and permeability.
Option (C) Soil groups – Refers to classification of soils based on various characteristics.
Option (D) Soil aggregates – Clusters of soil particles bound together, part of soil structure.
