Previous issue date: 2012 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES) / Funda??o de Amparo ? Pesquisa do estado de Minas Gerais (FAPEMIG) / O objetivo do trabalho foi avaliar o efeito do uso de composto org?nico de ind?stria de fia??o e tecelagem sobre a qualidade do substrato e crescimento de esp?cies arb?reas do cerrado em uma cascalheira no munic?pio de Diamantina, MG. A disserta??o foi estruturada em quatro cap?tulos. O primeiro refere-se ? revis?o bibliogr?fica visando o entendimento dos conceitos que foram abordados no estudo. No segundo capitulo, a influ?ncia do composto no substrato foi avaliada por meio das altera??es nos atributos qu?micos (pH, mat?ria org?nica (MO), soma de bases (SB), CTC, satura??o por bases (V), f?sforo (P), pot?ssio (K), c?lcio (Ca2+), magn?sio (Mg2+), acidez troc?vel (Al3+), acidez potencial (H + Al) e satura??o por alum?nio (m)) e f?sicos (resist?ncia mec?nica a penetra??o (Rp) e granulometria) do substrato. Foi avaliada tamb?m a atividade microbiana: carbono da biomassa microbiana (CBM) respira??o microbiana (C-CO2) e quociente metab?lico (qCO2) ap?s aplica??o de cinco tratamentos: sem aplica??o de composto org?nico e diferentes concentra??es 0,0; 4,5; 9,0; 18,0 e 36,0 g dm-3 por cova. O delineamento foi sistem?tico tipo ?leque? sendo os tratamentos dispostos em tr?s blocos casualizados. A adi??o do composto proporcionou o aumento nos valores de pH, MO, SB, CTC, V e nutrientes (P, K, Ca2+ e Mg2+) e promoveu a redu??o de Al3+, H + Al e m. O substrato minerado apresentou valores elevados de Rp indicando a compacta??o na ?rea degradada pela extra??o de cascalho, mesmo ap?s a aplica??o do composto. A adi??o de doses crescentes do composto promoveu o aumento significativo de CBM e C-CO2 ao substrato minerado. O maior valor de qCO2 indicou efici?ncia da biomassa microbiana com a incorpora??o das menores doses do composto ao substrato quando comparado ao controle. O terceiro cap?tulo refere-se ao estudo do crescimento das esp?cies nativas Kielmeyera lathrophyton Saddi (Pau santo), Plathymenia reticulata Benth (Vinh?tico), Dalbergia miscolobium Benth (Jacarand? do cerrado) e Bowdichia virgilioides Kunth (Sucupira-preta) plantadas em delineamento sistem?tico tipo ?leque? submetidas a cinco tratamentos: sem aplica??o de composto org?nico e diferentes doses de composto 0,0; 4,5; 9,0; 18,0 e 36,0 g dm-3 por cova dispostos em tr?s blocos casualizados. Ap?s 12 meses, verificou-se que n?o houve diferen?a significativa entre os tratamentos para sobreviv?ncia e incremento em altura, di?metro e cobertura de copa para cada esp?cie. Ainda, de forma preliminar foi poss?vel determinar que a adi??o de 4,5 g dm-3 de composto na cova proporcionou maiores valores de incremento em altura, di?metro e cobertura de copa para Plathymenia reticulata e Bowdichia virgilioides. No quarto cap?tulo, foi realizado o plantio em linha de Chamaecrista debilis submetida a quatro tratamentos, 0,0; 30,0; 60,0 e 120,0 g dm-3 de composto como adubo por cova, dispostos em tr?s blocos casualizados. Os resultados indicaram que n?o houve diferen?a significativa entre as doses de composto aplicado para incremento em altura, di?metro e cobertura de copa. O maior valor de incremento em altura e cobertura de copa ocorreu sem a adi??o de composto de res?duo org?nico de ind?stria de fia??o e tecelagem e para di?metro com a aplica??o de 60,0 g dm-3, no entanto, ? necess?ria a realiza??o de avalia??es futuras. A taxa de sobreviv?ncia apresentou decr?scimo significativo com a aplica??o das maiores dosagens de composto org?nico. A esp?cie Chamaecrista debilis apresentou caracter?sticas importantes para recupera??o de ?rea degradada, como r?pido crescimento e produ??o de biomassa. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Ci?ncia Florestal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2012. / ABSTRACT The objective of the work was to evaluate the effect of the use of composed of organic residue spinning industry and weaving on the quality of the substratum and growth of arboreal species of the thicket in a gravol-pit in the municipality of Diamantina, MG. The dissertation was structured in four chapters. Being the first, regarding the bibliographical revision seeking the understanding of the concepts and theoretical questions of what was borded in the study. In the second I chapter, the influence of the compound in the substratum was evaluated through the alterations in the chemical attributes (pH, organic matter (MO), sum of bases (SB), CTC, saturation for bases (V), match (P), potassium (K), calcium (Ca2+), magnesium (Mg2+), exchangeable acidity (Al3+), potential acidity (H + Al) and saturation for aluminum (m)) and physical (mechanical resistance the penetration (Rp) and texture) of the substratum. As well as in the microbial activity of the same: carbon of the microbial biomass (CBM) microbial breathing (C-CO2) and metabolic quotient (qCO2) after application of five treatments: without application of organic composition and different concentrations 0; 4,5; 9,0; 18,0 and 36,0 g dm-3 for hole. The delineation was systematic type "fan" being the treatments disposed in three blocks unexpected. The addition of the compound stimulated the increase in the pH values, MO, SB, CTC, V and nutritious (P, K, Ca2+ and Mg2+) and it promoted the reduction of Al3+, H + Al and m. The mined substratum presented high values of Rp indicating the compactation in the area degraded by the gravel extraction, even after the application of the composed. The addition of growing doses of the compound promoted the significant increase of CBM and C-CO2 to the mined substratum. The largest qCO2 value indicated efficiency of the microbial biomass with the incorporation of the smallest dosages of the compound to the substratum when compared to the control. The third chapter, refers to the study of the growth of the native species Kielmeyera lathrophyton Saddi (sacred Wood), Plathymenia reticulata Benth (Vinh?tico), Dalbergia miscolobium Benth (Jacaranda of the Thicket) and Bowdichia virgilioides Kunth (Sucupira-black) planted in delineation systematic type " fan " submitted to five treatments: without application of organic composition and different doses of compound 0,0; 4,5; 9,0; 18,0 and 36,0 g dm-3 for hole disposed in three blocks unexpected. After 12 months, it was verified that there was not significant difference among the treatments for survival and increment in height, diameter and top covering for each species. Still, in a preliminary way it was possible to determine that the addition of 45 g dm-3 of compound of organic residue of textile industry in the hole stimulated larger increment values in height, diameter and top covering for Plathymenia reticulata and Bowdichia virgilioides. In the fourth chapter, the planting was made in line of Chamaecrista debilis submitted to four treatments, 0,0; 30,0; 60,0 and 120,0 g dm-3 compound dm-3 as fertilizer for hole, disposed in three blocks inexpected. The results indicated that there was not significant difference among compound applied for increment in height and diameter. The largest increment value in height and diameter happened without the addition and with the application of 60,0 g dm-3 of compound of organic residue of textile industry, however it is necessary the accomplishment of future evaluations. The survival rate presented significant decrease with the application of the largest doses of organic compund. The species Chamaecrista debilis presented important characteristics for recovery of degraded area, as fast growth and biomass production.
