Resumo: | The mine bauxite Barro Alto is the first ore economically viable bauxite in the central- west region of Brazil and has peculiar characteristics. After mining, the chemical, physical and biological soil characteristics are unsuitable for replanting, making it difficult to environmental recovery. The aim of this study was to evaluate the use of green manure in organic and mineral fertilizer and their influence on the physical and chemical attributes of the area to be reclaimed and implementation of an agroforestry system. This work was developed in degraded area located at Barro Alto, Goias The study area has 5000 m2 and is in the process of recovery since February 2012. Two cycles of planting green manure the first in March 2012 were performed, and the second. In December 2012 the treatments were: 1- pigeonpea; 2- jack bean; 3- sunn hemp; 4- velvet bean; 5- milhet intercropping with faba bean; 6 - millet intercropped with beans pork; 7 - milhet intercropped with sunn hemp; 8- milhet intercropped with velvet bean and three nutrient sources: 1- fertilization with phosphate Arad; 2- the cattle manure; 3- mineral fertilizer controlled release fertilizers. Phytotechnical the characteristics of green manures (height, chlorophyll content, biomass production and nutrient accumulation ) , chemical properties (pH, macronutrients and soil organic matter) and physical soil (bulk density, macro and micropores, volume total pore, gravimetric moisture and penetration resistance ). An agroforestry system using three species, apeiba (pioneer), the baru (middle) and pequi (climaceaes) was implemented in February 2013. The results showed that 17.1% of the biomass originated in pearl millet indicating legumes are the main factors of increase in that variable. The use of mineral source (NPK) significantly increased the biomass of green manure, nutrient accumulation and plant height in relation to the Arad phosphate and manure. With the introduction of green manuring, the content of exchangeable soil Al, H + Al and Al saturation (m%) reduced by 55%, 18.46% and 37.47% in relation to beginning of recovery, respectively. The use of green manure increased the soil organic matter, base saturation and potassium in 156%, 41.71% and 52.41% in relation to beginning of recovery, respectively. The macro and microporosity, in addition to resistance to penetration, improved after 18 months of implementation of the recovery, demonstrating that cropping practices adopted for recovery of degraded in the study area is being active. After 270 days of planting of tree species cover crops and sources used did not influence the height and diameter. The apeiba excelled at increase in height and diameter than the baru and pequi. |

Após a lavra, as características químicas, físicas e biológicas do solo são inadequadas para a revegetação, o que dificulta a recuperação ambiental. Este trabalho teve como objetivo avaliar as alterações em atributos do solo durante a recuperação inicial de área de mineração de bauxita com utilização de adubos verdes, manejada com diferentes adubações e introdução de sistema agroflorestal. A área de estudo possui 5 mil m2 e está em processo de recuperação desde fevereiro de 2012. Foram realizados dois ciclos de plantio de adubo verde, o primeiro em março de 2012 e o segundo em dezembro de 2012. Os tratamentos foram: 1 - feijão guandu; 2 - feijão-de-porco; 3 - crotalária juncea; 4 - mucuna preta; 5 - milheto consorciado com feijão guandu; 6 - milheto consorciado com feijão-de-porco; 7 - milheto consorciado com crotalária; 8 - milheto consorciado com mucuna. E as três fontes de adubação foram: 1- adubação com fosfato de Arad; 2 - adubação com esterco bovino; 3 - adubação com fertilizante mineral de liberação controlada. Foram analisadas as características fitotécnicas dos adubos verdes (altura, teor de clorofila, produção de fitomassa e acúmulo de nutrientes), atributos químicos (pH, macronutrientes e matéria orgânica do solo) e físicos do solo (densidade do solo, macro e microporos, volume total de poros, umidade gravimétrica e resistência à penetração). Foi implementado em fevereiro de 2013 um sistema agroflorestal com utilização de três espécies, a apeiba (Apeiba tibourbou Aubl.) (pioneira), o baru (Dipteryx ala) (secundária) e o pequi (Caryocar brasiliense Cambess) (climáceaes). Os resultados obtidos demonstraram que 17,1% da fitomassa tiveram origem no milheto, indicando serem as leguminosas os principais fatores de incremento nessa variável. A utilização da fonte mineral (NPK) aumentou significativamente a fitomassa da adubação verde, acúmulo de nutrientes e altura das plantas em relação ao fosfato de Arad e ao esterco bovino. Com a introdução da adubação verde, o teor de Al trocável do solo, H+Al e da saturação por Al (m %) reduziram em 55%, 18,46% e 37,47% em relação ao início da recuperação, respectivamente. A utilização dos adubos verdes aumentou o teor de matéria orgânica, saturação de bases e potássio em 156%, 41,71% e 52,41% em relação ao início da recuperação, respectivamente. A macro e a microporosidade, além da resistência à penetração, melhoraram após 18 meses de implantação da recuperação, demonstrando que o manejo adotado para recuperação da área degradada no estudo está sendo atuante. Após 270 dias de plantio das espécies arbóreas, as plantas de cobertura e as fontes utilizadas não influenciaram a altura e o diâmetro. A apeiba se destacou no incremento de altura e diâmetro em relação ao baru e pequi.Submitted by Erika Demachki (erikademachki@gmail.com) on 2015-10-15T21:20:28Z No. of bitstreams: 2 Tese - Átila Reis da Silva - 2014.pdf: 2830062 bytes, checksum: 7da9def57c8e3eade6e13f2ed1ebb3f8 (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Approved for entry into archive by Erika Demachki (erikademachki@gmail.com) on 2015-10-15T21:21:41Z (GMT) No. of bitstreams: 2 Tese - Átila Reis da Silva - 2014.pdf: 2830062 bytes, checksum: 7da9def57c8e3eade6e13f2ed1ebb3f8 (MD5) license_rdf: 23148 bytes, checksum: 9da0b6dfac957114c6a7714714b86306 (MD5)Made available in DSpace on 2015-10-15T21:21:42Z (GMT).

description |
The mine bauxite Barro Alto is the first ore economically viable bauxite in the central- west region of Brazil and has peculiar characteristics. After mining, the chemical, physical and biological soil characteristics are unsuitable for replanting, making it difficult to environmental recovery. The aim of this study was to evaluate the use of green manure in organic and mineral fertilizer and their influence on the physical and chemical attributes of the area to be reclaimed and implementation of an agroforestry system. This work was developed in degraded area located at Barro Alto, Goias The study area has 5000 m2 and is in the process of recovery since February 2012. Two cycles of planting green manure the first in March 2012 were performed, and the second. In December 2012 the treatments were: 1- pigeonpea; 2- jack bean; 3- sunn hemp; 4- velvet bean; 5- milhet intercropping with faba bean; 6 - millet intercropped with beans pork; 7 - milhet intercropped with sunn hemp; 8- milhet intercropped with velvet bean and three nutrient sources: 1- fertilization with phosphate Arad; 2- the cattle manure; 3- mineral fertilizer controlled release fertilizers. Phytotechnical the characteristics of green manures (height, chlorophyll content, biomass production and nutrient accumulation ) , chemical properties (pH, macronutrients and soil organic matter) and physical soil (bulk density, macro and micropores, volume total pore, gravimetric moisture and penetration resistance ). An agroforestry system using three species, apeiba (pioneer), the baru (middle) and pequi (climaceaes) was implemented in February 2013. The results showed that 17.1% of the biomass originated in pearl millet indicating legumes are the main factors of increase in that variable. The use of mineral source (NPK) significantly increased the biomass of green manure, nutrient accumulation and plant height in relation to the Arad phosphate and manure. With the introduction of green manuring, the content of exchangeable soil Al, H + Al and Al saturation (m%) reduced by 55%, 18.46% and 37.47% in relation to beginning of recovery, respectively. The use of green manure increased the soil organic matter, base saturation and potassium in 156%, 41.71% and 52.41% in relation to beginning of recovery, respectively. The macro and microporosity, in addition to resistance to penetration, improved after 18 months of implementation of the recovery, demonstrating that cropping practices adopted for recovery of degraded in the study area is being active. After 270 days of planting of tree species cover crops and sources used did not influence the height and diameter. The apeiba excelled at increase in height and diameter than the baru and pequi. |
