FROM Mineral Fertilization to Biofertilization (II):
Life in the soil: The Key of its Fertility
As commented on previous post, since middle of 19th Century the chemical síntesis of fertilizers opened the door for a new chemical agriculture. This model was favoured by the explosive development of the New Chemical Industry.
The aim was to end with the dependence of agriculture on livestock (contribution of fertilizers of animal origin) since these were limited and the growth of the world population demanded greater production and greater contributions..
Nowadays we know that Soil Fertility is based on the balance between its organic and mineral compounds.
This Balance is mantained by the microorganisms present in soil, in short: Life of the Soild is the Key of its Fertility.
Soil is a natural storage of nutrients, the key of this warehouse belongs to the microorganisms living on it
By eliminating the microorganisms responsible for soil fertility, the balance is broken.
A lifeless soil is totally dependent on the constant supply of nutrients in directly assimilable mineral forms.
The mineral forms provided in excess are quickly leached, evaporated or blocked in forms that cannot be assimilated by the plant, which are retained in the soil, increasing the problem
⇑ % Mineral Salts → Soil extreme mineralization → ⇓ Soil microbiology
In conclusion, a lifeless soil loses its natural ability to feed plants.
Soil Fertility requieres a Balanced supply:
MINERAL FERTILIZERS + ORGANIC FERTILIZERS
Mordern Agriculture seeks to recover the lost balance by the contribution of organic fertilizers and BIOFERTILIZERS based on beneficial MICROORGANISMS such as
