QUALIDADE E QUANTIDADE


Pode dizer-se que agricultura orgânica é agricultura de qualidade. Ora,não é de qualidade,mas de quantidade,que mais de mil milhões de pessoas,que fome padecem, deste vário mundo, está à espera. Ora,também não é a qualidade que mais preocupa cerca de metade da população mundial que tem no arroz a base do seu sustento. O mesmo se aplica ao trigo,ao milho,à soja,e a outros bens da mesma família,indispensáveis á produção de alimento e de energia para uma grande parte das gentes que povoam a Terra. Sendo assim,a agricultura orgânica serve apenas a uma minoria que já está bem sevida.

A PROPÓSITO DA AGRICULTURA ORGÂNICA


Como alimentar o Mundo com a Agricultura Orgânica, ou que lugar tem a Agricultura Orgânica no Mundo,quando a população se está aproximando dos 7 mil milhões,quando uma boa parte dela tem o arroz como base do seu sustento,quando é elevada a presença de solos degradados,pobres em matéria orgânica e nutrientes essenciais,quando as necessidades em alimentos são satisfeitas,em parte considerável,com recurso a adubos químicos,quando é imperioso produzir barato,face à triste realidade da pobreza,da miséria mesmo?

BIOLOGIC AGRICULTURE AND FERTILISATION

Resumo

SANTOS, Joaquim Quelhas dos. Biologic agriculture and fertilisation. Rev. de Ciências Agrárias [online]. 2012, vol.35, n.1, pp. 49-58. ISSN 0871-018X.
Taking in account the present level of knowledge, it doesn’t seem to be correct to interdict the use of some production factors, namely mineral fertilizers, in the so called biologic agriculture. In fact, it is easy to prove that mineral fertilizers have a decisive contribution to increase the production without environmental damage in atmosphere, soils, waters and agricultural products. It is so, if mineral fertilizers are correctly used, which means how much, what kind, when and how to use them in order to satisfy the plant needs and characteristic of the local soil and climate conditions. In fact, it is perfectly acceptable that in terms of some aspects of sanitary quality, the so called biologic products can be more dangerous then same products obtained by traditional agriculture
