Production of pearl millet irrigated with different levels of brackish water and organic matter. Author(s): ARAUJO, G. G. L. de; SIGNOR, D.; REGITANO NETO, A. The objective is to determine the growth, yield and chemical characteristics of pearl millet irrigated with different levels of brackish water and organic matter in two cultivation cycles. The experim... ... Repository: BDPA Publication year: 2020
Multivariate analysis of images in spectrophotometric methods: quantification of soil organic matter. Author(s): MADARI, B. E. Soil organic matter (SOM) is usually quantified by Walkley-Black titration method or using a spectrophotometric method. This study proposes an alternative method for quantification of SOM using digita... ... Repository: BDPA Publication year: 2021
Soil and plant responses to pyrogenic organic matter: carbon stability and symbiotic patterns. Author(s): SAGRILO, E. Soil amendment with pyrogenic organic matter (PyOM) can sequester carbon, increase mutualistic root symbioses with arbuscular mycorrhizal fungi and nitrogen-fixing rhizobia, and hence improve crop yie... ...

Organic matter of an Amazonian sandy soil as affected by forest burning. Author(s): COSTA, F. de S. In the Amazon region, forest burning is still common in spite of the governmental control. Pyrogenic C produced by the fire, due to its aromatic structure, may represent a C pool of small turnover rat... ... Repository: BDPA Publication year: 2017
Dynamic of organic matter in the conversion of primary forest in rubber tree in the central amazon region. The removal of primry forest causes a significant reduction of the microbial biomass of C and soil fertility. With the introduction of stands of rubber tress can be a continuos recovery of the amount... ... Repository: BDPA Publication year: 2007

S. de Single-layer graphene oxide decorated with silver nanoparticles (GO@AgNPs) nanohybrid is an emerging material to applications in nanotechnology such as catalysis, biosensors, composites, and antimicro... ... Repository: BDPA Publication year: 2018
Humic substance fractions and attributes of histosols and related high-organic-matter soils form Brazil. Knowledge of the distribution of soil organic matter (SOM) fractions is important in managing soils toward a sustainable agricultural system ina tropical environment, However, data on Histosols in lim... ... Repository: BDPA Publication year: 2007
Organic matter in areas under secondary forests and pasture. Author(s): CORREIA, M. E. F.; BALIEIRO, F. de C. The objective of this study was to evaluate the soil carbon stock (Stock C) and bulk density, the chemical and granulometric fractions of the organic matter and the isotopic signal of the soil δ1... ...
