One of the most important aspects of organic farming is building
up the fertility of the soil. This can be done either by using synthetic or
organic types of fertilizers. For years, many farmers used only synthetic
fertilizers on their farm. The Synthetic types are manufactured products, while
organic fertilizers are obtained from animal
manure, plants or naturally occurring minerals.
Like our bodies, plants also need nutrients to function and
grow properly. The soil contains many of the essential nutrients needed by
plants. There are 16 nutrient elements needed by plants to grow and most soils
contain large reserves of 13 nutrients.
The constant use of the soil and constant erosion by wind and rain will
eventually deplete the nutrients.
The advantage of this form of fertilization is not only that
they contain unprocessed nutrients mentioned above but also organic matter and
humus which serves as soil conditioning.
As compared to the processed synthetic fertilizers, organic
fertilizers gives out the nutrients
slowly so that plant roots are less likely to be burnt due to high dose of
chemicals. Organic matter improves soil
structure, drainage, and retains the moisture and microbial life of the soil.
Sufficient amount of this can help ensure that nutrients are available to
plants on a steady basis and that the soil structure enhances the root to grow.
There are several types of organic fertilizers. The
Plant Based which are high in nitrogen and potassium, like Soybean Meals which
has 7% nitrogen, Corn Gluten with 10%
nitrogen that is quick to breakdown, Alfalfa Meal with a moderate 2% -3% Nitrogen and some
traces of minerals. Another type is the
Animal Based which is actually by-products of meat and dairy processing like
Blood Meals from the slaughtering industry which contain 14% nitrogen, Bone
Meal with 11% phosphorous and 22% calcium, Fish Meal with 10% nitrogen and Animal
Manure whose nutrient composition varies based on the animal and the method of
storage. Lastly, there is Composting
Method which is considered as the best organic fertilizer. They are made from
plant, animal, and mineral based materials.
It has a low but good balance of nutrients and high on organic matters
that help feed the soil’s microorganisms. The nicest thing about composting is
that no matter what material you start with, the end products will be fairly similar.
Indeed! The secret to growing nutritious fruits
and vegetables, abundant flowers, trees and shrubs is by creating a living soil
using organic fertilizers – Cheap, Effective and Eco-friendly.
