Resumo: | During the second half of the 20th century, the introduction of new chemical agriculture technologies brought about a revolution in food production, but this has also cause deep deterioration in our relationships with the natural environment. In developing tropical countries, record yields were accompanied by rural exodus, widespread deforestation and loss of topsoil. The stonemeal research described herein is an alternative to such practices as it is an environmental friendly and socially responsible technology based on soil rejuvenation and conservation by means of the addition of natural rock powders that are rich in phosphorous, calcium, magnesium, potassium and micronutrients. The research adopted an inter-disciplinary approach and was conducted among small farmers of a rural community located in the state of Minas Gerais, Brazil. The major goal was to demonstrate that there is a harmless cheap and simple alternative to fertilizing degraded or impoverished soils, which allow farmers to sustain high productivity and to remain on their plots of land. Results have confirmed the economic, environmental and productive feasibility and advantage of the stonemeal technique for corn, rise, manioc, sugar cane and horticultural species, when compared to the use of chemical fertilizers. The fertilization of the soil with rocks, allows the understanding of the natural processes, which maintain production levels while building a sustainable fertile soil. |

Nos países tropicais, especialmente aqueles em desenvolvimento, os recordes de safras foram acompanhados de êxodo rural, devastação e erosão dos solos. A pesquisa sobre o uso da técnica de Rochagemaqui descrita pretende ser uma alternativa tecnológicaambientalmente correta e socialmente responsável para os problemas mencionados. A técnica de Rochagem está baseada no rejuvenescimento e conservação de solos por meio da adição de pós de determinados tipos de rochas enriquecidas em fósforo, cálcio, magnésio, potássio e micronutrientes. A pesquisa foi desenvolvida segundo os pressupostos interdisciplinares e foi conduzida em meio aos agricultores familiares de um assentamento rural localizado no Estado de Minas Gerais, Brasil. Os principais resultados demonstraram que essa tecnologia é uma alternativa de baixo custo e extremamente simples para fertilizar ou recuperar solos degradados, que pode conduzir a sustentabilidade e, também, produções compatíveis de forma que os agricultores possam permanecer em seus lotes. Os resultados da pesquisa mostram que o uso da Rochagem apresenta vantagens econômicas, ambientais e produtivas significativas, em culturas de milho, arroz, mandioca, cana-de-açúcar, e hortifrutigranjeiros em comparação à adubação convencional. A fertilização da terra pela própria terra segue os ensinamentos da natureza (processos naturais), mantendo os níveis de produção comsustentabilidade e preservação dos solos.Em processamentoAcademia Brasileira de Ciências2017-12-07T04:44:02Z2017-12-07T04:44:02Z2006info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfAn.
