A conscious agriculture: Organic Farming

A conscious agriculture: Organic Farming
17/01/2015 Margarida Moreira

Organic farming is a conscious agriculture and is trying to correct the errors of traditional agriculture of the 20th century, which devastated vegetation shrub, abuse of fertilizers and pesticides and the use of heavy machinery.

It does not mean that return to the past through organic farming, because never turn back. -Vincent Gerbe

Organic farming rejects the agrochemical practices and departs techniques that alter the food. Traditional farming submits the food to toxic products (people also end up eating it!): Substances to change the color of fruits and vegetables, and excessive radiation treatments (and often unnecessary).

In Organic farming gives a priority to the natural balance and sustainability, because “organic” indicates “that which relates to life.” -Vincent Gerbe

A major concern of organic farming is organic fertilization through compounds (humus: decomposition of plant debris and animals by action of soil organisms) and green manures (seedlings / planted in order to promote soil Fertility) rich in Nitrogen, which are incorporated in soil.

In the industrial agriculture, farmers do not care (a lot) about the soil as a whole, focusing mainly on the three fundamental elements: Nitrogen (N), Phosphorus (P) and Potassium (K) circulating in excess by plants, causing toxic nitrites with carcinogenic effects (facts posted by Voison brothers).

Such industrial interventions put (and placed) a risk to human health and biodiversity: comprehensive soil erosion, deforestation, loss of fauna and flora, forcing the rapid growth of the crops that contributes to a lower resistance to pests and diseases and, as a cycle, involves the use of chemicals in an attempt to revive agricultural production.

To obtain a natural equilibrium, the procedure is still to crop rotation, thus allowing the fallow (temporary resting of the ground). Professor Manuel Ângelo Rodrigues, Polytechnic Institute of Bragança, Portugal explains that the soil is like a pot with nutrients and whenever you make a production, this consumes nutrients from the soil, to “return to the pot” is necessary to fertilize the soil (in depth).

Humanity, soil and plants work as a whole, so a natural agriculture trigger a healthier life cycle.

No one can call himself a “environmentalist”, if […] not strive to use food in organic farming. -Vincent Gerbe
