de Oliveira, Ivanildo Amorim; Campos, Milton César Costa; de Freitas, Ludmila; de Aquino, Renato Eleotério [UNESP]; da Cunha, José MaurícioMade available in DSpace on 2022-04-28T19:09:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-06-01; Converting natural ecosystems into agro-ecosystems often reduces soil organic carbon content by decreasing carbon input, as well as by increasing erosion losses and organic matter decomposition rate. This study aimed at evaluating carbon stocks, soil aggregate stability, and spatial variability of some ...

de Oliviera, Ivanildo Amorim [UNESP]; Campos, Milton César Costa; Eleotério Aquino, Renato [UNESP]; Freitas, Ludmila [UNESP]Made available in DSpace on 2022-04-28T18:59:27Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-12-01; The soil management system can modify the natural distribution of the soil attributes and, consequently, the variability of the soil aggregation and organic matter content. Thus, the aim of this work was to evaluate the aggregate stability and organic matter content spatial distribution on a Haplic Camb...

No. of bitstreams: 0 Previous issue date: 2015-01-01; There is a lack of studies focusing on the spatial behavior of chemical attributes in the Amazon. In this sense, the objective of this study was to use geostatistical techniques in the evaluation of chemical attributes in agroforestry soil and sugarcane in Humaitá, Amazonas. The study was conducted in a...

Brito, Wildson Benedito Mendes; Campos, Milton César Costa; de Souza, Fernando Gomes; Silva, Laércio Santos [UNESP]; da Cunha, José MaurícioMade available in DSpace on 2022-04-29T08:32:31Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-04-01; Changes in primary cover for agricultural crops in Amazonas region influence the phenomenon of spatial variability in soil properties. This phenomenon is still studied assuming that the spatial data is isotropic, but does not consider the anisotropic pattern of soil properties. Thus, the aim of this wor...
Characterization of backyards and socioeconomic aspects of residents who grow m...
Carvalho, Dayanne de Souza; Campos, Milton César Costa; Lima, Janaína Paolucci Sales deIn rural areas, as in settlements in the Brazilian Amazon region, family farmers grow medicinal plants in their backyards as an option in view of the deficiency in providing adequate health services and necessary medicines, in search of benefits for food and health. From this context, the objective was to characterize backyards and the socioeconomic profile of residents of the São Francisco settlement, in Canut...
