    This document describes an experiment on soil acidity and adjusting pH. The experiment involves applying different amendments like vinegar and antacid tablets to soil samples in plastic cups to change the pH. Seedlings are then planted to observe their growth under different pH conditions. The results will show which amendments are most effective at adjusting soil pH to support optimal plant growth. Regular soil testing and monitoring pH is important for determining nutrient needs and selecting appropriate amendments.

    Exercise No. 8
    Soil Acidity and Adjusting Soil pH

    INTRODUCTION
    Soil acidity and pH are crucial for plant health and productivity, as they affect
    nutrient availability, microbial activity, and overall plant growth. A low pH indicates higher
    acidity, while a high pH indicates alkalinity. Soil acidity affects the solubility of essential
    minerals, making certain nutrients less available to plants. High soil acidity can lead to
    toxic elements like aluminum and manganese, harming plant roots and hindering growth.
    To maintain optimal growing conditions, soil pH can be adjusted using lime application,
    elemental sulfur, or organic matter amendment.
    Regular soil testing and monitoring are essential for determining current pH and
    monitoring adjustments. Understanding soil acidity helps in selecting appropriate
    amendments and managing nutrient deficiencies or toxicities effectively.

    METHODOLOGY
    In 2 kg of garden soil that has been screened or cleansed to remove large pebbles
    or plant debris. Then 12 pieces of 3.5 oz. plastic salad cups. Antacid (Kremil-S):12 pieces;
    crushed or powdered, (corn or munggo): 36 pieces of seeds. Vinegar (100 mL); Marking
    pen (or masking tape, a ruler, and a ball pen) Plastic syringe (10 mL).

    Table 1: The amendments used under different treatments.


    Treatment Amendment
    T0 None (control)
    T1 10 mL vinegar
    T2 10 mL vinegar + 1tablet kremil-S
    T3 10 mL vinegar + 2 tablets kremil-S
    T4 1 tablet kremil-S
    RESULT AND DISCUSSION
    You’ll need 12 plastic cups, garden soil, a got hot nail, a knife, or a drill, vinegar,
    and antacid tablets (kremil-S) to complete this experiment. First, use a hot nail, knife, or
    drill to make a few holes in the cups’ bases. Then, gently fill each of the 12 cups with
    garden soil until they are about completely filled, and mark each cup with a number (T0R1,
    T0R2, ect.). Continue these two cups with label “T0” aside to use as controls. In order to
    make the other cups, go through the treatment guide one at a time. Put the amendment,
    using the above table as a reference, after transferring the soil from the cup into a clean
    area. Before using, crush the antacid pills and carefully mix or stir the soil with the
    amendment for at least a minute before putting it back in the plastic cup. After putting the
    soil back, use a syringe to inject 10 mL of water into the T0, T4, and T4 containers. Verify
    that the soil in each cup is just moist enough, and add additional water if required to keep
    the moisture level in each cup roughly the same. Set the cups aside in a sunny location,
    but keep them covered to prevent damage. Place the cups in a random order, and make
    sure they are all properly labeled. Plant three seeds in each cup after the cups have
    existed for five days, planting them deep enough to covered by soil. During the first
    germination, notice the cups each day, take photos on a daily basis, and check the soil’s
    moisture regularly. Five days following the first germination, if a number of seedlings have
    appeared in a cup, trim to one plant per cup. The height of the plant should be measured
    from the base to top of the plant, or from the root to the tip of the longest leaf, depending
    on which is longer, within ten days following the initial germination.

    CONCLUSION
    It is essential to comprehend soil acidity and adjusting soil pH in order to produce
    healthy plants, maximize nutrient availability, and avoid imbalances that affect growth. The
    possibility of achieving effective plant development and productivity will increase if you
    know about soil pH and use the proper practices, even if you are a farmer, gardener, or
    horticulture enthusiast.
