  1. More waec Agric Questions and Answers

    IDENTIFY SPECIMENS A&B
    A=> Organic manure

    B=> Inorganic manure

    IMPORTANCE OF A&B

    1. They promote the activities of Micro organisms in the soil.

    2. They add more humus to the soil, thus increase the nutrient for plant growth.

    3. They improve soil structure by binding loose particles together.

    4. Help to conserve soil water.

    5. Help in acration of the soil.

  2. DIFFERENCE BETWEEN ORGANIC MANURE & INORGANIC MANURE
    ORGANIC MANURE

    1. It makes up of organic materials.

    2. It contains Microbs.

    3. It has low nutrient density.

    4. High residual value due to a long time taken to decay.

    5.may serve as soil mulch.

    6. It stabilizes soil temperature.

    7. It releases nutrients after microbial decomposeition.

  3. thanks for this answers and questions, i've been searching for this for quite some times now.
    Thanks admin, i so much love your blog.

    (Get the diagram to show the experiment)
    The diagram is label as
    *Crucible
    *Dry soil sample.
    *Wire guaze
    *Flame
    *Tripod stand.
    *Bunsen Burner

  5. QUESTIONS
    A=> Give an appropriate title to the above experiment set up.
    B. Name the parts Labelled A-F
    C. Discribe the experiment set up in the diagram above.

    ANSWERS
    A. The title is to determine organic matter content in the soil
    . Material required: soil sample containing organic Matter, crucible, bunsen burner, tripod stand, Wire guaza, string rod, weighing Balance and desicator
    Result and calculation.
    maps of empty crucible =20g
    weight of Empty crucible =20g
    weight of crucible + fresh soil = 30g
    weight of fresh soil only=(30-20)g =10g
    weight of crucible + dry soil = 28g
    weight of dried soil only =(28-20)g=8g weight of crucible + burnt soil=27.4g
    Weight of burnt soil only=(27.4-20)g =7.4g
    Weight of humus removed = Weight of dried soil-mass of burntsoil=(8.0-74g)=0.6g
    percentage of humus in the soil sample = weight of humus*100/weight of dried soil = 0.6/8*100/01.=0.6*125=75%
