“…Positive and significant correlation between OM, C-BMS and, the enzyme acid phosphatase, (r) of 0.71 and 0.90 (p≤0.01) respectively. Data that corroborate with those obtained by [83][84][85][86][87][88][89][90][91][92], when they found significant correlations between OM and acid phosphatase activity. These types of correlations are important from the point of stability of the soil fertility of the different systems.…”

Aims: In the Brazilian Amazon, the practices and use of agroforestry systems (SAF) are increasingly used, the proper management of them helps to improve soil properties and also to prevent their degradation. In this context, the objective of this work was to evaluate the biological attributes of the soil in the oil palm cultivation systems with intercropping. Study Design: The experimental design used was completely randomized with four repetitions and six treatments: Oil palm (Elaeis guineense Jacq.) interspersed with pineapple (OPi), bean (OBe), banana (OBa), yucca (OYu) and Brachiaria humidicola (OPa), as well as adjacent area only with Brachiaria humidicola as a witness (Pa). The Tukey test was used at a level of 5% probability in samples analyzed at a depth of 0-0.0 m, to compare the means of the variables evaluated. Place and Duration of Study: The experimental area is located of São João da Baliza, vicinal 26, km 12, with geographic coordinates of reference 00º.51'13.3''N and 60º00'19.8''W, the altitude of 100 msnm and, distant to 352 km from the capital Boa Vista, state of Roraima realized in 2016. Results: The TOC presented values between 4.70 and 9.45 g kg-1, being the highest values found in the interim systems OYu, Pa, OBa, highlighting the intermediate system OPi that presented the lowest levels. The highest basal respiration values of the soil (RBS) (23.50 mg C-CO2 kg-1 soil h-1) and carbon from microbial biomass (C-BMS) (116.0 mg C microbiano kg-1 soil) were verified in the pasture system. Likewise, for the urease and acid phosphatase activity, the grass system stands out as a control with values of (148.42 g NH4+ g-1 soil 2 h-1) y (230 μg de p-nitrofenol g-1 soil h-1) followed by palm with grass and yucca systems. However, the β-glucosidase activity (51.22 μg p-nitrofenol g-1 h-1) it was positively influenced by the oil palm system with yucca. On the other hand, the system interspersed with pineapple showed a higher metabolic coefficient (qCO2) (0.36 mg C-CO2 g-1 C-BMS h-1). It can be concluded that the pasture system (Pa) is presented as a more stable environment, followed by interspersed systems of oil palm with grass (OPa) and yucca (OYu).

“…Quesada et al (2020) verificaram em seus estudos que as variações nas concentrações de orgânico em solos da Floresta Amazônica são explicados pelas propriedades químicas e físicas do solo. No entanto, estudos realizados na região amazônica revelam a fragilidade e a importância desse ecossistema, diversos autores vêm discutindo o uso e a ocupação dos solos amazônicos, estudos esses sobre o comportamento dos solos no que se refere aos sistemas de cultivos (Colodel et al, 2018;Oliveira et al, 2016;Damaceno & Lobato, 2015;Camargo et al, 2010;Oliveira, 2006), especialmente acerca da conversão de ecossistemas naturais para sistemas agrícolas ou pecuários, características morfológicas, químicas e físicas dos solos. Malheiro, Higuchi & Santos (2009), analisando a estrutura da floresta tropical úmida do município de Alta Floresta, em Mato Grosso, explicam que a caracterização da região amazônica é muito importante para definir a diversidade Research, Society and Development, v. 10, n. 9, e34210918157, 2021 (CC BY 4.0) | ISSN 2525-3409 | DOI: http://dx.doi.org/10.33448/rsd-v10i9.18157 vegetacional, permitindo, dessa maneira, saber quais são as espécies que compõem tais áreas e de que modo elas estão distribuídas num estrato arbóreo.…”

O objetivo deste estudo foi identificar as feições morfológicas e pedogenética dos solos e suas características químicas e físicas na bacia hidrográfica do Médio Curso do Rio Teles Pires (BHMTP). Para isso, foram estudados seis perfis de solo, em trincheiras, ao longo das margens direita e esquerda do Rio Teles Pires, localizados nas Fazenda Encanto da Natureza, Fazenda São José, Rio Teles Pires, Fazenda Estrada do Espanhol, Comunidade Bonfim e Fazenda Vaca Branca. Foram feitas em cada horizonte as análises morfológicas descritivas e posteriormente coletados solos para análises físicas e químicas. Por meio da interpretação das avaliações morfológicas dos perfis, associada aos resultados de análises físico-químicas dos solos, os solos foram classificados até o quarto nível categórico, sendo dois ARGISSOLO VERMELHO-AMARELO Distrófico típico (PVAd), localizados sobre a margem esquerda do rio; dois Latossolos, LATOSSOLO VERMELHO Eutrófico típico (LVe) e LATOSSOLO VERMELHO-AMARELO Distrófico típico (LVAd) localizados à direita do rio; um GLEISSOLO HÁPLICO Tb Distrófico plintossólico (GXbd) localizado à esquerda e um CAMBISSOLO HÁPLICO Tb Distrófico (CXbd) à direita do rio Teles Pires. Em geral, os solos apresentaram texturas médias em todos os perfis. A saturação por Al3+ foi elevada na maioria dos horizontes, refletindo os baixos valores de pH e menores teores de Ca2+, Mg2+, K+ e, consequentemente, menores saturação por bases, exceto o LVe, cuja CTC foi alta. Todos os solos apresentaram média capacidade de troca de cátions (CTC), fato que reflete a mineralogia típica de solos intemperizados.

“…Knowledge of the soil quality through its physical-chemical and biological attributes is essential to assess impacted and cropped areas (Colodel et al, 2018), as well as the lowland areas of the Amazon (Fajardo et al, 2009). Therefore, knowing the spatial variability of soil attributes may assist in the management of areas of native Acai in this ecosystem with the use of geo-technologies, which supports the high-productive potential of the areas with the rich-natural fertility of the soils and productivity in the islands.…”

For several decades, the Acai orchards (acaizais) have directly influenced the survival of the families in the Amazonian floodplains. In this period, the production of the Acai fruit for local consumption was ceased and became an export item produced in intensive management, resulting in an increase in orchards in the floodplains and the emergence of dryland plantations, no longer representing a typical extractive activity in the Amazon. The objective of this study was to map the classes of use and coverage, and the occurrences of the Acai orchards massifs, as well as to analyze the physical and chemical parameters of five islands in the municipality of Igarapé-Miri, State of Pará, Brazil, where there is a great occurrence of productive Acai orchards. This work evaluated the following islands: Jarimbu, Mamangal, Itaboca, Mutirão, and Buçu, where geolocalized collections were carried out in the areas with the highest occurrence of Acai orchards, both to assist in the classification of images and for soil sampling. August 2019 Planet images were processed using the unsupervised method, where seven classes of cover use were obtained: hydrography, exposed soil, urban, alluvial, lowland, arboreal, and agriculture areas. Therefore, occurrences of productive orchards were identified and correlated to the good attributes of soil fertility in the floodplains under continuous flooding and sedimentation. The correlation confirmed the higher productivity of Acai in the Alluvial and Lowland classes, which predominate in the evaluated area, presenting soils considered fertile with a loam-clay-silty and loam -silty texture, high base saturation (greater than 50%), high organic matter content, and significant presence of potassium and phosphorus.
