Soil Science Reviewer for the Agriculturist Licensure Examination

Soil Science underpins Crop Science and is examined in its own right. Items move quickly between physical, chemical and biological properties, so a candidate who has learned them as separate lists tends to struggle.

What Soil Science covers on the board exam

  • Soil physical properties: texture, structure, bulk density, porosity and water movement.
  • Soil chemistry: cation exchange capacity, pH, buffering and nutrient availability.
  • Soil fertility, fertiliser materials, rates and placement.
  • Soil genesis, classification and survey.
  • Soil conservation, degradation and management of problem soils.

Study note. Texture drives water, water drives aeration, and aeration drives nutrient availability. Reason down that chain and most items unlock.

Sample Mixed Questions (Supplemental Reviewer) questions with answers and explanations

Board-style items taken from the Soil Science bank. Every answer is explained, which is the part that makes a review question worth doing twice.

  1. Which description best defines soil in modern soil science?

    • A. A mixture of fertilizer nutrients and decomposed plant residues spread over the land surface each season
    • B. Any unconsolidated material lying above bedrock, regardless of biological activity or of the processes that produced it
    • C. A dynamic natural body of mineral and organic constituents, water, air, and organisms that develops at Earth’s surface and supports multiple functions correct
    • D. A loose layer composed only of weathered mineral particles, with no water, air, or living organisms present

    Why: Soil is a dynamic natural body formed through interacting physical, chemical, and biological processes; it is more than weathered rock alone.

  2. What is a pedon?

    • A. The smallest three-dimensional body of soil that can represent the nature and arrangement of its horizons correct
    • B. A group of similar soil series occurring within a province
    • C. The mineral portion of a surface horizon
    • D. The vertical face exposed in a soil pit

    Why: A pedon is the basic three-dimensional sampling/classification unit used to represent a soil.

  3. What does the term polypedon denote?

    • A. A single horizon having both eluvial and illuvial properties
    • B. A contiguous group of similar pedons that constitutes a soil individual in the landscape correct
    • C. A soil profile that contains more than one parent material
    • D. A laboratory composite made from multiple soil samples

    Why: A polypedon is an assemblage of contiguous, similar pedons and is treated as a soil individual.

  4. Which branch of soil science emphasizes soil genesis, morphology, and classification as a natural body?

    • A. Petrology
    • B. Edaphology
    • C. Pedology correct
    • D. Agronomy

    Why: Pedology studies soils as natural bodies, including their formation, morphology, and classification.

What does this Soil Science reviewer cost?

You can answer 40 questions across AgLE Online Review for free. After that, a one-time ₱49 payment unlocks every available subject and future reviewer updates. No Google account or recurring subscription is required.

How many Soil Science questions are there?

The built-in Soil Science bank holds 600 distinct questions across 5 topics, with approved additions published live. Every item is a separate question — the count is not padded with reworded copies of the same one.

Can I practise Soil Science by topic?

Yes. Opening Soil Science in the reviewer shows its topics first, and a session can be run on a single topic or across all of them. You can also choose Practice Mode for instant explanations or Exam Mode for timed board conditions.

Are these actual AgLE board questions?

No, and no reviewer that claims otherwise should be trusted. These are board-style practice items written and curated to match the coverage and difficulty of the Agriculturist Licensure Examination. Consult the current PRC Table of Specifications for the official scope.
