1. Sensitivity analysis of the AquaCrop model for wheat crop in Campos Gerais region, Paraná
ABSTRACT The use of crop modeling can be useful to understand the interactions between the soil-plant-atmosphere system. The objective of this study was to evaluate sensitivity analysis of the AquaCrop model parameters for wheat crop in the Campos Gerais Region. The varietie tested was TBIO Sinuelo in Castro, Ponta Grossa and Itaberá cities. The analyzed pa

2. Effect of biochar, chicken litter and NPK on soil fertility, growth and nutrition of sweet orange Pêra-Rio in with Antropic Soil (Terra Mulata) in the Amazonas / Efeito do uso de biocarvão, cama de frango e NPK na fertilidade do solo, no crescimento e na nutrição da laranjeira "Pêra-Rio" em Latossolo Amarelo com a Antrópico (Terra Mulata) no Amazonas
The Amazonian soil presents mostly low natural fertility, however, patches of dark colored soil have been discovered, and are characterized by intense high fertility called Anthropogenic Dark Earths. Adjacent to these soils, Terra Mulata calls attention to the less dark coloration, lower fertility and higher extensions. The orange Pêra-Rio is an important c

4. Retorno ao solo de nutrientes de serrapilheira de Eucalyptus cloeziana no cerrado do Distrito Federal.
RESUMO: O objetivo deste trabalho foi comparar procedências de Eucalyptus cloeziana quanto à queda de serrapilheira e aos nutrientes potencialmente retornáveis ao solo por essa via no Cerrado, em Planaltina-DF. O experimento foi implantado em um Latossolo Vermelho, argiloso, distrófico a uma altitude de 1000 m. As procedências avaliadas foram: 11008 de

6. Seleção de áreas aptas a disposição de lodo de estações de tratamento de esgoto com fins agrícolas / Selection of areas suitable for the disposal of sludge stations sewage treatment for agriculture
Overcrowding in urban centers has spawned many impacts on the environment, highlighting the waste generated by their activities. To properly allocate these wastes, technologies are developed such as those involved in sewage treatment. However, this form of treatment also generates waste, which must be treated and disposed of properly. The sludge is a byprodu

7. Desempenho de plantas de cobertura no controle da erosão hídrica no Sul de Minas Gerais / Performance of cover crops to control erosion in the South of Minas Gerais
The erosion initiates with the impact of the raindrop on the soil surface, causing the transport of sediment, nutrients and organic matter. To reduce this erosion, the use of conservation practices, such as proper management and planting of cover crops that reduce these losses, is essential. The objective of this study was to evaluate the potential of plant

8. Nitrogênio e enxofre para gramínea forrageira: atributos do solo e aspectos metabólicos, nutricionais e produtivos da planta / Nitrogen and sulphur for graminaceous forage plants: soil attributes and metabolic, nutritional and productive aspects of plants
The nitrogen and sulphur availability in soil might influence plant growth, affecting the vegetal production. The objectives of this work were: a) to assess fertilization with nitrogen and sulphur rates on yield of Brachiaria brizantha cv. Marandu (Marandu palisadegrass) under establishment in a soil supporting degrading pasture of Brachiaria decumbens (Sign

9. REQUERIMENTOS NUTRICIONAIS DE MUDAS DE FAVELA, PEQUI, MAROLO E BARBATIMÃO / The nutritional requirements of seedlings of Favela, Pequi, Marolo and BarbatimÃo
The establishment of fruit and medicinal species of native cerrado may soften the negative environmental aspect arising from deforestation, and improve their utilization which today is restricted to local populations. However, depends on a better understanding of the nutritional requirements of these species. Aiming to assess the nutritional aspects and effe

11. Efeito da aplicaÃÃo de efluente do tratamento secundÃrio de Ãgua residuÃria da suinocultura na meso e macrofauna de solo cultivado com minimilho
Swine livestock is a common economic practice in the South of the country, including West of ParanÃ, generating a large amount of waste with high-polluting power. These are usually thrown on the ground as fertilizer, increasing soil fertility, leading to greater productivity of crops, although they may bring risks to the environment when improperly managed,

12. Estudo de uma metodologia para estimar a quantidade de carbono em amostras de solo utilizando espectroscopia de emissão óptica com plasma induzido por laser (LIBS) / Study of a methodology to estimate the carbon content in soil samples by laser induced breakdown spectroscopy (LIBS)
Soils are an important component in the biogeochemical cycle of carbon, storing about four times more carbon that biomass plants and nearly three times more than the atmosphere. Moreover, the carbon content is directly related on the capacity of water retention, fertility, among others properties. Thus, soil carbon quantification in field conditions is an im
