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 suchpractices as it is an environmental friendly and socially responsible technology based on soil rejuvenationand 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 wasconducted among small farmers of a rural community located in the state of Minas Gerais, Brazil. Themajor goal was to demonstrate that there is a harmless cheap and simple alternative to fertilizing degradedor impoverished soils, which allow farmers to sustain high productivity and to remain on their plots ofland. Results have confirmed the economic, environmental and productive feasibility and advantage of thestonemeal technique for corn, rise, manioc, sugar cane and horticultural species, when compared to the use ofchemical 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. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778408 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.78 |
