Resumo: | Strategies to intensify livestock production in the Cerrado must consider improving the quality of the soil and the forage offered to animals. In addition, sustainability in meat and milk production is an international demand that will have a crucial impact on the continuity of rural properties. In this sense, integrated production systems, especially crop-livestock-forest integration and the use of technologies are highlighted. The objectives of the present work were to evaluate the soil quality and the current evapotranspiration in integrated in the recovery of degraded pastures. The experiment was implemented in Rio Verde - Goiás in November 2017, in a Red Latosol with a very clayey texture soil and composed of seven treatments, and from the third onwards there was soil tilling and fertilization in new forage and, from the fourth, production between eucalyptus rows: Degraded Pasture - 1.36 AU ha-1 with 507 days of grazing; Fertilized Pasture - 1.68 AU ha-1 with 507 days of grazing (fertilization in established pasture); Conventional - 2.05 AU ha-1 with 355 days of grazing; Lavoura-Floresta integration (production of vegetables and fruit); Livestock-Forest integration - 2.68 AU ha-1 with 507 days of grazing (immediate), Crop-Livestock-Forest hay integration - 4.15 AU ha-1 with 157 days of grazing after hay cutting and Crop-Livestock integration -Silage forest - 3.26 AU ha-1 with 157 days of grazing after cutting the consortium with forage sorghum. The forage planted was BRS RB331 Ipyporã, forage sorghum BRS655 and eucalyptus the clone AEC-2111. The lines were implanted with a simple line, 22 meters between lines and 2 meters between plants. After four months of planting, an evaluation of the chemical, physical and microbiological quality of the soil was carried out, in addition to the evaluation of evapotranspiration and biomass by remote sensing. The parameters soil density, total porosity, macropores, S index and soil aeration capacity did not differ statistically. Degraded pastures showed higher microporosity than other treatments. The indices indicate greater water retention in the pasture degraded by the greater amount of micropores due to the compaction processes. All treatments were below the critical S limit of 0.045, whose values below indicate soil structure degradation. Higher population density of fungi and bacteria was observed, as well as mycorrhizal fungi spores in treatment soils without soil disturbance. The results referring to soil fertility were responsive only in treatments where liming was performed. The remote sensing data were accurate in determining the current biomass and evapotranspiration in the treatments. At 24 months were determined of experiment, were determined the water infiltration speed curves and the respective basic infiltration speed values, the soil resistance to penetration, the current evapotranspiration of the cultures and the measurement of the chemical attributes in the treatments in response to the management of soil fertility. In the cultivation systems in which the soil was prepared, the basic infiltration speed tended to be higher, with emphasis on the livestock-forest integration system with eucalyptus cultivation intercropped with brachiaria for grazing and the planting of the brachiaria done with conventional tillage. The lesser resistance of the soil to the penetration was provided by the diversity of species in the silviagricultural systems. In the livestock-forest integration treatment, the highest mean ETa was observed (1.33 mm day-1) and, in the degraded pasture treatment, the lowest mean ETa (0.96 mm day-1) was observed. The integrated systems were adapted to the region's seasonality, suffering water stress in the dry season and with space-time heterogeneity in the wet season. There was an increase in organic matter, pH, potassium and base saturation and a decrease in aluminum saturation in conditions of non-revolving soil and replacement of nutrients through liming and fertilization. There was no effect of the forest component on soil attributes in relation to areas without eucalyptus in the period of 2 years. The fertilized treatments provided an increase in the stocking rate, showing viability in its implantation due to the nutrient cycling provided by the animals and plants. |

Além disso, a sustentabilidade na produção de carne e leite é uma demanda internacional e que terá impacto crucial na continuidade das propriedades rurais. Nesse sentido, os sistemas integrados de produção, especialmente a integração lavoura-pecuária-floresta e o uso de tecnologias ganham destaque. Os objetivos do presente trabalho foram avaliar a qualidade do solo e a evapotranspiração atual em integrados na recuperação de pastagens degradadas. O experimento foi implantado em Rio Verde – Goiás em novembro de 2017, em um Latossolo Vermelho com solo de textura muito argilosa e composto por sete tratamentos, sendo que do terceiro em diante houve revolvimento do solo e adubação em nova forrageira e, a partir do quarto, produção entre renques de eucalipto: Pasto Degradado - 1,36 UA ha-1 com 507 dias de pastejo; Pasto Adubado - 1,68 UA ha-1 com 507 dias de pastejo (adubação no pasto estabelecido); Convencional - 2,05 UA ha-1 com 355 dias de pastejo; integração Lavoura- Floresta (produção de olerícolas e frutíferas); integração Pecuária-Floresta - 2,68 UA ha-1 com 507 dias de pastejo (imediato), integração Lavoura-Pecuária-Floresta feno - 4,15 UA ha- 1 com 157 dias de pastejo após corte do feno e integração Lavoura-Pecuária-Floresta silagem - 3,26 UA ha-1 com 157 dias de pastejo após corte do consórcio com sorgo forrageiro. A forrageira implantada foi o BRS RB331 Ipyporã, o sorgo forrageiro o BRS655 e o eucalipto o clone AEC-2111. Os renques foram implantados com linha simples, 22 metros entre linhas e 2 metros entre plantas. Realizou-se, aos quatro meses de plantio, avaliação da qualidade química, física e microbiológica do solo, além da avalição da evapotranspiração e biomassa por sensoriamento remoto. Os parâmetros densidade do solo, porosidade total, macroporos, índice S e capacidade de aeração do solo não diferiram estatisticamente. As pastagens degradadas apresentaram maior microporosidade em relação aos demais tratamentos. Os índices indicam maior retenção de água na pastagem degradada pela maior quantidade de microporos devido aos processos de compactação. Todos os tratamentos estavam abaixo do limite crítico de S de 0,045, cujos valores abaixo indicam degradação da estrutura do solo. Observou-se maior densidade populacional de fungos e bactérias, além de esporos de fungos micorrízicos em solos dos tratamentos sem revolvimento do solo. Os resultados referentes à fertilidade do solo foram responsivos apenas nos tratamentos onde a calagem foi realizada. Os dados de sensoriamento remoto foram precisos na determinação da biomassa atual e da evapotranspiração nos tratamentos. Aos 24 meses de experimento, foram determinados as curvas de velocidade de infiltração de água e os respectivos valores de velocidade de infiltração básica, a resistência do solo à penetração, a evapotranspiração atual das culturas a mensuração dos atributos químicos nos tratamentos em resposta ao manejo de fertilidade dos solos. Nos sistemas de cultivo em que houve preparo do solo, a velocidade de infiltração básica tendeu a ser maior, com destaque para o sistema de integração pecuária-floresta com cultivo de eucalipto consorciado com braquiária para pastejo e o plantio da braquiária feito com preparo convencional do solo. A menor resistência do solo à penetração foi proporcionada pela diversidade de espécies nos sistemas silviagrícolas. No tratamento integração pecuária-floresta observou-se a maior média de ETa (1,33 mm dia-1) e, no tratamento pastagem degrada, a menor média de ETa (0,96 mm dia-1). Os sistemas integrados se adequaram à sazonalidade da região, sofrendo estresse hídrico na época seca e com heterogeneidade espaço-temporal na época úmida. Observou-se aumento da matéria orgânica, pH, potássio e saturação por bases e diminuição da saturação por alumínio em condições de não revolvimento do solo e reposição dos nutrientes através da calagem e adubação. Não houve efeito do componente florestal nos atributos químicos do solo em relação às áreas sem eucalipto no período de 2 anos. Os tratamentos adubados proporcionaram aumento da taxa de lotação animal, demonstrando viabilidade em sua implantação graças a ciclagem de nutrientes proporcionada pelos animais e plantas.Submitted by Franciele Moreira (francielemoreyra@gmail.com) on 2020-10-27T20:48:42Z No. of bitstreams: 2 license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5) Tese - Leonnardo Cruvinel Furquim - 2020.pdf: 4074688 bytes, checksum: 5f169b5f8aefd57228f7fcf3bc55082a (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2020-10-28T11:11:42Z (GMT) No. of bitstreams: 2 license_rdf: 805 bytes, checksum: 4460e5956bc1d1639be9ae6146a50347 (MD5) Tese - Leonnardo Cruvinel Furquim - 2020.pdf: 4074688 bytes, checksum: 5f169b5f8aefd57228f7fcf3bc55082a (MD5)Made available in DSpace on 2020-10-28T11:11:43Z (GMT).

description |
Strategies to intensify livestock production in the Cerrado must consider improving the quality of the soil and the forage offered to animals. In addition, sustainability in meat and milk production is an international demand that will have a crucial impact on the continuity of rural properties. In this sense, integrated production systems, especially crop-livestock-forest integration and the use of technologies are highlighted. The objectives of the present work were to evaluate the soil quality and the current evapotranspiration in integrated in the recovery of degraded pastures. The experiment was implemented in Rio Verde - Goiás in November 2017, in a Red Latosol with a very clayey texture soil and composed of seven treatments, and from the third onwards there was soil tilling and fertilization in new forage and, from the fourth, production between eucalyptus rows: Degraded Pasture - 1.36 AU ha-1 with 507 days of grazing; Fertilized Pasture - 1.68 AU ha-1 with 507 days of grazing (fertilization in established pasture); Conventional - 2.05 AU ha-1 with 355 days of grazing; Lavoura-Floresta integration (production of vegetables and fruit); Livestock-Forest integration - 2.68 AU ha-1 with 507 days of grazing (immediate), Crop-Livestock-Forest hay integration - 4.15 AU ha-1 with 157 days of grazing after hay cutting and Crop-Livestock integration -Silage forest - 3.26 AU ha-1 with 157 days of grazing after cutting the consortium with forage sorghum. The forage planted was BRS RB331 Ipyporã, forage sorghum BRS655 and eucalyptus the clone AEC-2111. The lines were implanted with a simple line, 22 meters between lines and 2 meters between plants. After four months of planting, an evaluation of the chemical, physical and microbiological quality of the soil was carried out, in addition to the evaluation of evapotranspiration and biomass by remote sensing. The parameters soil density, total porosity, macropores, S index and soil aeration capacity did not differ statistically. Degraded pastures showed higher microporosity than other treatments. The indices indicate greater water retention in the pasture degraded by the greater amount of micropores due to the compaction processes. All treatments were below the critical S limit of 0.045, whose values below indicate soil structure degradation. Higher population density of fungi and bacteria was observed, as well as mycorrhizal fungi spores in treatment soils without soil disturbance. The results referring to soil fertility were responsive only in treatments where liming was performed. The remote sensing data were accurate in determining the current biomass and evapotranspiration in the treatments. At 24 months were determined of experiment, were determined the water infiltration speed curves and the respective basic infiltration speed values, the soil resistance to penetration, the current evapotranspiration of the cultures and the measurement of the chemical attributes in the treatments in response to the management of soil fertility. In the cultivation systems in which the soil was prepared, the basic infiltration speed tended to be higher, with emphasis on the livestock-forest integration system with eucalyptus cultivation intercropped with brachiaria for grazing and the planting of the brachiaria done with conventional tillage. The lesser resistance of the soil to the penetration was provided by the diversity of species in the silviagricultural systems. In the livestock-forest integration treatment, the highest mean ETa was observed (1.33 mm day-1) and, in the degraded pasture treatment, the lowest mean ETa (0.96 mm day-1) was observed. The integrated systems were adapted to the region's seasonality, suffering water stress in the dry season and with space-time heterogeneity in the wet season. There was an increase in organic matter, pH, potassium and base saturation and a decrease in aluminum saturation in conditions of non-revolving soil and replacement of nutrients through liming and fertilization. There was no effect of the forest component on soil attributes in relation to areas without eucalyptus in the period of 2 years. The fertilized treatments provided an increase in the stocking rate, showing viability in its implantation due to the nutrient cycling provided by the animals and plants. |
