The document provides a lesson plan about organic fertilizers for students. The objectives are for students to understand organic fertilizers, their uses and value, and how to apply them properly based on NPK factors. Various types of organic fertilizers are discussed such as compost, manure, and seaweed. Students learn the advantages of organic fertilizers like improving soil structure and being more environmentally friendly. The lesson involves a video, discussion, and a hands-on laboratory activity where students make their own organic fertilizer and learn its importance over synthetic fertilizers for crop growth.
2. I. OBJECTIVES
At the end of the lesson, the students should
be able to:
I. Be able to define organic fertilizers.
II. Classify the uses and value of organic fertilizers.
III. Explain organic fertilizer, grade and ratio
according to the appropriate application
considering the NPK factor.
IV. Assess the direct and residual effects of organic
fertilizer on growth, yield and quality of plant.

4. Value Integration:
For them to become aware of the uses and
importance of using organic fertilizer. They will be able to
know the benefits of using organic fertilizer instead of
synthetic fertilizer.
Strategies:
Discussion about the topic and this will require the
students to have participations or recitations
The field/laboratory activity will be performed by group
with 4 members only. The students are required to
bring all the materials needed.

6. Teacher's Activity Student's Activity
A. Setting Standards
Differentiate between organic and
inorganic fertilizer
Explain the concepts, benefits and
uses of organic fertilizers
Give the types of organic fertilizer
B. Lesson Proper
Ok class our topic for today is all about
organic fertilizer. Let me give you first
the definition of it.
Yes ma'am/sir.
An organic fertilizer is a fertilizer that is
derived from organic sources, including
organic compost, cattle manures,
poultry droppings and domestic
sewage.
7. Now who can give another example of
organic fertilizer?
Seaweeds, animal manures and composts
How can we used seaweed as a fertilizer? By simply grinding or pulverizing dried
seaweed and sprinkling it around plants.
Give example of compost that we can
used as organic fertilizer, why?
Vegetable and fruit peels, like banana
peels. It is good for our plants because this
is a potassium-rich fertilizer.
8. Ok that's good. Now these are
some examples of organic
fertilizer:
•Alfala Meal
-best use as soil conditioner
prior to planting crops.
•Cottonseed Meal
-useful for conditioning gardens.
•Corn Gluten Meal
-soil stabilizer
•Rock Phosphate
-contain large amounts of
phosphate as well as other
essential nutrients.
9. •Cow Manure
-help to make an excellent compost
addition
•Chicken or Poultry Manure
-best use is after harvesting crops or
before you begin another gardening
cycle.
•Earthworm Castings
-it is considered a great addition to
flower and vegetable gardens.
•Greensand
-it is a high calcium fertilizer also
contains iron and potassium
•Compost
-should be added before or after
planting as a soil refresher in between
growing seasons for gardens that are
constantly in use.
10. Soybean Meal
-fairly useful as a long term soil
conditioner.
•Blood Meal
-best to apply before planting
anything to your garden
•Feather Meal
-use it prior to make planting in
order to give the soil a nutrient
boost.
•Bat Guano
-most effective when used as a
foliar spray or a compost tea, it
can be also applied between
crop plantings and as a soil
refresher.
11. •Fish Meal
-it is a fairly fast-acting
fertilizer, good for corn crops.
•Seaweed
-it is highly beneficial to grain
crops as well as those that
need high levels of potassium.
Now these are the advantages of organic
fertilizer.
•Organic fertilizers are natural, in that the
nutrients they possess are strictly
comprised of plant- or animal-based
materials. Either byproducts or end
products of natural processes. Cow
manure, decaying leaves, and food
compost are all forms of organic fertilizer.
12. •Organic fertilizers are an environmentally
sound investment in your soil and plant’s
future. They are created from the
byproducts or end products of naturally
occurring processes, which means they
come directly from nature itself. Even
though they take longer to work, and the
exact ratio of nutrients is indeterminable,
organic fertilizers provide a healthy food
source for your plants and protect your
little part of the environment
•Organic fertilizer release nutrients, as they
break down, improving the soil and its
ability to hold water and nutrients. Given
time, they make the soil and plants
healthier and hardier. Organic fertilizers
carry little risk of a toxic overdose of
chemicals, but they require a breakdown of
microorganisms to release nutrients,
limiting their seasonal effectiveness and
potentially increasing the amount of time
they take to feed your plants.
13. •Organic fertilizers improve garden soil
where they are used. They not only
assist with water retention, they also
make the soil lighter so that more air is
available to the plant roots. Organic
fertilizers don’t waste nutrients like
their chemical counterparts. Nor are
they likely to create a build-up of salts
that could dampen plant growth. These
types of fertilizers even tend to be less
likely to burn tender plant roots than
synthetic products.
Ok, now what is the importance
of organic fertilizer?
It improves soil structure because of the organic
matter present in organic fertilizer, as a result the
soil's ability to hold onto water and nutrients
increases.
Yeah that's good.
If you want healthier plants, a healthier you,
and a healthier environment, organic is your
best bet.
14. C. Enhancement Activities
Okay class, since I already
discussed to you the concept
about the organic fertilizer, I
will show you a short video
presentation on how organic
fertilizers were made out of
dried manures, and compost.
You should take down notes
the step by step process.
Is that clear with you, class?
After that, we will have our
field/laboratory activity which you
will group by 4 (your groupings will
be announce after you watch the
video)
Yes ma’am/sir.
15. D. Generalization
I know you’ve learn a lot from today’s
discussion especially in our
laboratory, who can summarize or
discuss the proper way of making an
organic fertilizer, specifically what
type of organic fertilizer that you
work?
Additionally, what is the importance
of using organic fertilizer to the crops
instead of using synthetic fertilizer?
(call 2 students to answer and
discuss)
(Very good)
(Students will raise their hand)
16. It is important to have
knowledge about the proper
way of making and using a
fertilizer in a specific crop.
Have a nice day class! You did a
good job today!
Thank you ma’am/sir.
17. E. Valuing
Students can already justify
the difference between
organic and synthetic
fertilizer. They show the
ability to make their own
organic fertilizer at their
home. And most especially,
they can initiates to use
organic fertilizer instead of
chemical fertilizers.
18. IV.
