MODULE 1 & 2
Let’s Evaluate!
1. Among the different methods of assessing soil fertility, which is best to use when
your crop is not yet grown in the field? Justify your choice.
Let’s Check for Understanding
1. List down the 16 essential elements together with their functions, symptoms of
deficiencies and toxicity.
2. Discuss briefly how would a deficiency symptom of a mobile nutrient be
manifested in plants.
3. You were hired as a researcher to conduct field fertilizer trial to test the validity
of a software which can predict fertilizer needs of a specific area. How will you
go about doing this particular research? Considering that the software needs an
input of soil fertility data, do you consider soil variablity a problem in this
research?
4. In a field fertilizer experiment, when do you expect response of applied
fertilizers? Why?
5. What is “hidden hunger” in plants? How can you overcome this problem?
Let’s Reflect
1. In plant analysis, plant parts and stage of crop growth are important
considerations in sampling. Why? Can’t you just use any part of the plant to be
analyzed at any stage of growth? Explain.

Activity 2: I. Application. Solve the following problems showing your step-by-step
solution. Always indicate the unit use in your solution. Box your final answers.
1. You have a 50 kg bag of granular fertilizer with a label that reads 15-10-10. The
grade is 15-10-10, which is the percentage by weight of N, P as P2O5, and 10% by
weight K2O. Calculate the amount (in kg) of N, P2O5 and K2O is in the bag. (10pts)
2. A farmer have the following fertilizers to used: complete (15-15-15), ammophos
(16-20-0) and ammosul (21-0-0). He asked you how much of these fertilizers he has to
apply to his 2 hectares rice field. The certain area calls for a recommendation of 120-60-
60 kg N-P2O5-K2O/ha

______________________________________________________________________________________________________________
MODULE 1 & 2
a. Compute the amount of each fertilizer material needed to meet the recommendation
(in kg). 10pts
b. What is the approximate ratio of fertilizer elements? 2pts
c. How much will the farmer spend for all the fertilizers to be applied in his 2 hectares
rice field if:
1 bag ammophos= P1,200.00
1 bag ammosul = P1,500.00
1 bag complete = P1,250.00
1 bag = 50kg
Let’s Evaluate!
1. Describe the specific influence of microorganisms to nutrient availability; hence, on
plant growth and development.
2. What is contact exchange?
Let’s Check for Understanding
1. Discuss fully how chemical, physical and biological properties of soils interact with
each other thus, influencing nutrient availability.
2. What is ion exchange? What is its importance to agriculture?
3. What is cation exchange? Cite specific examples for the occurrence of cation
exchange in soils. Describe the importance of this process in soils.
4. What is the % base saturation of a soil with the exchange sites occupied by
5. Ca, Na, H, and Mg in the amount of 10, 2, 5 and 8 me / 100 gm, respectively. The
cation exchange capacity of the soil is 25 me/100 gm.
6. Cite instances whereby anion exchange process is important.
7. Enumerate and describe the ways by which ions move from the soil to the plant
roots.
Let’s Reflect
1. In what way does application or placement of fertilizers affect the movement of ions
from soil to roots? Cite examples.
2. What is complementary ion effect? How does this process influence availability of
nutrients to plants?
3. Differentiate passive from active ion transports.
