to the harvested parts or to the
harvest in a more refined state.

4. These are examples of crops

5. 2. Cultural Requirements of crops
 Cultural methods are agriculture practices
used to enhance crop and prevent weed, pest
or disease problems without the use of
chemical substances.
 Examples include the selection of
appropriate varieties and planting sites;
proper timing and density of plantings
and irrigation.

7. A. Applying fertilizer
Fertilizer is any organic or inorganic
material that is added to soil to supply
nutrients essential to the growth of
plants.

8. Two kinds of fertilizer
1. Organic fertilizer – derived from
vegetable and animal waste and
decomposed plants and animal remains.
Example: decomposed animal manure,
green manure, worm castings.

9. 2. Inorganic Fertilizer – man-made
fertilizer. Example: Urea, Ammonium
Sulfate

10. Determination of fertilizer needs:
The amount and kind of fertilizer to
be added to the soil depends
primarily upon:
The nutrient requirement of the
crop, and
How much nutrient the soil can
apply.

11. Methods of fertilizer application:
1. Basal method – the fertilizer is applied
first before or during planting.

12. 2. Side-dressing or Top-dressing the
fertilizer is applied to a crop that is
already growing in the field.

13. 3. Spraying or Foliar – starter solution
fertilizer may be sprayed on seedlings,
poured on the seedbed then into the
transplant hole at transplanting time to
assure good seedling vigor and rapid
growth of new transplants.

14. Major elements needed by plants:
 Nitrogen – for healthy growth of leaves and
flowers
 Phosphorous – for good root and stem
development
 Potassium – for better leaves, stems, flowers.
It also produces bigger and heavier fruits.
Fertilizers especially inorganic should be applied
in the right amount and at the proper time or
else they will defeat the purpose.
