Structural features of humic acids extracted from integrated crop-livestock-forest system. Soil organic matter (SOM) and their humic fractions (e.g., Humic Acids, HA) are considered a relevant soil quality indicator, due to its direct relation with biological, chemical and physical soil pro... ...

Changes in metabolic profiling of sugarcane leaves induced by endophytic diazotrophic bacteria and humic acids. Plant growth-promoting bacteria (PGPB) and humic acids (HA) have been used as biostimulants in field conditions. The complete genomic and proteomic transcription of Herbaspirillum seropedicae and Gluc... ... Repositório: BDPA Ano de publicação: 2018
Performance test of granulated potassium chloride with humic acids addition. The objective of this work was to evaluate the efficiency of granulated fertilizers based on potassium chloride with humic acids in the production of dry matter and the accumulation of macronutrients... ...

Molecular characteristics and bioactivity of humic acids isolated from vermicomposts. Vermitechnology is an effective composting method which transforms different residual biomasses into nutrient rich organic fertilizer. In fact, the mature vermicompost is a renewed organic source suit... ... Repositório: BDPA Ano de publicação: 2014
Studies of the compositions of humic acids from Amazonian Dark Earth soils. The compositions of humic acids (HAs) isolated from cultivated and forested "Terra Preta de Índio" or Amazonian Dark Earth soils (anthropogenic soils) were compared with those from adjacent non-anthro... ...

Humic acids induce the expression of nitrate transporters in passion-fruit seedlings. The management of organic fertilization in passion fruit has been carried out empirically based on the responses of the crops and the experience of farmers. Knowledge of the physiological responses of... ... Repositório: BDPA Ano de publicação: 2023
Mitigation of salt stress of tomato using pre-treatment with humic acids. Repositório: BDPA Ano de publicação: 2014
Spectroscopy characterization of humic acids isolated from Amazonian dark earth soils (Terra Preta De Índio). The environmental organic matter is the link between the biosphere, geosphere, hydrosphere and atmosphere and is fundamental for ecosystem sustainability. Estimates of the total mass of organic carbon... ... Repositório: BDPA Ano de publicação: 2009
Structural characteristics of soil humic acids in coffee-cultivation systems: 13C NMR and analytical pyrolysis. Structural characterization of soil organic matter is still poorly understood in Brazilian agroecosystems. We aimed to identify the qualitative changes of soil humic acids as influenced by agroforestr... ... Repositório: BDPA Ano de publicação: 2011
