X-ray Microtomography for Investigating Pore Space and Its Relation to Water Retention and Conduction in Highly Weathered Soils. Author(s): VAZ, C. M. P. Abstract: Soil structure controls soil hydraulic properties and is linked to soil aggregation processes. The aggregation processes of Oxisols are controlled mainly by clay mineralogy and biological ac... ... Repository: BDPA Publication year: 2023
Biochar chemistry in a weathered tropical soil: kinetics of phosphorus sorption. Author(s): MORALES, M. M.; COMERFORD, n. b.; BEHLING, M.; ABREU, D. C. de; GUERRINI, I. A. The phosphorus (P) chemistry of biochar (BC)-amended soils is poorly understood. This statement is based on the lack of published research attempting a comprehensive characterization of biochar?s infl... ... Repository: BDPA Publication year: 2021
Lime movement through highly weathered soil profiles. Author(s): DENARDIN, J. E.; VAZ, C. M. P. Repository: BDPA Publication year: 2019
Can co-application of silicate rock powder and humic-like acids increase nutrient uptake and plant growth in weathered tropical soil? Author(s): MARTINS, E. de S. Silicate rock powder (SRP) restores the fertility of weathered soils. However, its slow nutrientrelease is a disadvantage for short-duration crops. Humic-like acids (HLAs) are plantbiostimulants that... ... Repository: BDPA Publication year: 2022
Long term effects of manure, charcoal and mineral fertilization on crop production and fertility on a highly weathered Central Amazonian upland soil. Objectives: (1) quantify the effects of charcoal, organic, and inorganic fertilization on soil fertility and crop production; and (2) to evaluate the sustainability of charcoal additions in terms of m... ...

Management impacts on soil organic matter of tropical soils. Author(s): CASTRO, G. S. A. Increased soil organic matter (SOM) improves the cation exchange capacity of tropical weathered soils, and liming is required to achieve high yields in these soils. Despite a decrease in SOM in the sh... ... Repository: BDPA Publication year: 2015
A poultry litter-derived organomineral phosphate fertilizer has higher agronomic effectiveness than conventional phosphate fertilizer applied to field-grown maize and soybean. Author(s): BENITES, V. de M. Inadequate disposal of poultry litter (PL) may promote eutrophication of water bodies due to its high nutrient content, including phosphorus (P). Thus, recycling P from PL to produce organomineral fer... ... Repository: BDPA Publication year: 2021
Nutritional diagnosis in a Conilon coffee plantation in the northern region of the Espírito Santo state. Author(s): FONTANA, A. The soils of Coastal Tablelands are characterized by low natural fertility, which reinforces the importance of assessing soil fertility and leaf nutrition of crops. The objective of this study is to p... ... Repository: BDPA Publication year: 2022
Diagnóstico nutricional em plantação de café Conilon na região norte do estado do Espírito Santo. Author(s): PIRES, I. F.; FONTANA, A.; PARTELLI, F. L.; CAMPANHARO, A.; ROCHA, J. R.; RODRIGUES, J. D. Os solos dos Tabuleiros Costeiros têm como característica a baixa fertilidade natural, o que reforça a importância da avaliação da fertilidade do solo e nutrição das folhas das culturas agrícolas. Obj... ... Repository: BDPA Publication year: 2022
Characterization and classification of floodplain soils in the Porto Alegre metropolitan region, RS, Brazil. Author(s): SILVA NETO, L. de F. da In the Porto Alegre metropolitan region (PAMR) there are a significant proportion of floodplain soils, mainly Planosols and Gleysols, in relation to upland soils. This study aimed to evaluate the morp... ... Repository: BDPA Publication year: 2015
