Critical levels and sufficiency ranges for leaf nutrient diagnosis by two metho...
Souza, Henrique Antunes de; Vieira, Paulo Fernando de Melo Jorge; Rozane, Danilo Eduardo; Sagrilo, Edvaldo; Leite, Luiz Fernando CarvalhoEstablishing sufficiency ranges and critical levels of nutrients are important for a correct evaluation of plant nutrition through leaf diagnosis. This study aimed to propose critical levels and sufficiency ranges of macro and micronutrients based on leaf diagnosis of soybean plants. The database used was generated from 86 samples of the third trifoliate leaf without petiole, collected during the flowering stag...
Soil fertility and nutritional status of elephant grass fertilized with organic...
Pereira, Graziella de Andrade Carvalho; Primo, Anacláudia Alves; Meneses, Abner José Girão; Araújo, Maria Diana Melo deThe application of organic composts derived from animal husbandry or agro-industry is a promising option to improve nutrient cycling and supply of soils and, consequently, forage production. The objective of this study was to evaluate the soil chemical properties and the nutritional state of elephant grass in response to rates of organic fertilizer composted from the waste of small ruminant production and slaug...
Soil biological attributes in monoculture and integrated systems in the Cerrado...
Cunha, João Rodrigues da; Freitas, Rita de Cassia Alves de; Souza, Djalma Junior de Almeida Taveres; Gualberto, Adriano Veniciús SantanaThe implementation of integrated agricultural production systems is considered a promising strategy for sustainable agricultural intensification in Brazil. This study aimed to evaluate the effects of different monoculture and integrated production systems on the microbiological attributes and organic carbon of soil from the Cerrado region in Piauí, Brazil. Soil samples were collected from the 0.0-0.10-m layer i...
Spatial variability of carbon and nitrogen stocks in integrated management syst...
Vogado, Renato Falconeres; Souza, Henrique Antunes de; Matias, Sammy Sidney Rocha; Gualberto, Adriano Veniciús Santana; Cunha, João Rodrigues daThe conversion of the native Cerrado into agricultural systems promotes a reduction in the input of organic residues on the soil, which can compromise the contents of soil organic carbon. The spatial distribution of carbon and nitrogen stocks in the soil is normally influenced by environmental and anthropogenic factors. This research aimed to map and evaluate the spatial variability of carbon and nitrogen stock...

Quantificação de nutrientes nos frutos de goiabeiras adubadas com subproduto da...
Souza, Henrique Antunes de; Amorim, Daniel Angelucci de; Rozane, Danilo Eduardo; Natale, WilliamAs informações sobre a exportação de nutrientes do solo são importantes, pois, podem auxiliar programas de adubação e reposição de fertilizantes. Considerando que os trabalhos que avaliam os efeitos promovidos pela aplicação de subprodutos e resíduos são escassos, principalmente em culturas perenes, este trabalho teve por objetivo avaliar a saída de nutrientes do solo para os frutos de goiabeiras adubadas com o...
TRÂNSITO DE MÁQUINAS E RESISTÊNCIA DO SOLO À PENETRAÇÃO EM POMAR DE GOIABEIRAS
Souza, Wilson José Oliveira de; Rozane, Danilo Eduardo; Souza, Henrique Antunes de; Natale, William; Santos, Paulo André Fernandes dosO estudo foi conduzido em pomares comerciais de goiabeiras ‘Paluma’ e ‘Pedro Sato’, irrigados, que foram mapeados com GPS de navegação Garmin (Cx60). Houve a demarcação de 65 pontos de amostragem, demarcados em grade amostral de 21 x 21 m, sendo avaliadas a umidade gravimétrica e a resistência do solo à penetração (RSP), com auxilio de um penetrômetro automatizado, haste com cone tipo 3 com ângulo de 45º (RSP m...
