“…OM in the surface layer is very variable in space, since the roots (living organic matter) occupy a large volume of the soil and the process of decomposition of dead organic matter varies as a function of microbial activity and anthropic action. Oliveira et al (2021) state that there was a greater input of organic matter in the surface layer, resulting from the low mineralization in banana planting area.…”

The low natural fertility and compaction of agricultural soils in the Cerrado are the main limitations for agricultural production. Changes in management systems are necessary to optimize the use of natural resources. The objective of this study was to map and evaluate the presence of penetration resistance and its relationship with soil chemical attributes in pasture areas in the Cerrado of Piauí. The experiment was carried out in the municipality of Corrente-PI, Brazil. The area was divided into two sub-areas of 0.5 ha each: the first is remaining vegetation and the second is pasture. Fifty soil samples were collected in the 0.00-0.20 and 0.20-0.40 m layers, with a sampling grid of 10 x 10 m. The pH in water, organic matter, calcium, magnesium, and soil penetration resistance were analyzed. The introduction of animals in the pasture area increased soil compaction by 2%. Chemical attributes, pH, organic matter, calcium and magnesium vary according to soil compaction by 2%. The native forest area has soil penetration resistance at acceptable levels (<2 MPa) and availability of nutrients at adequate levels. The maps of variability of organic matter, calcium, magnesium and penetration resistance showed the heterogeneity of the areas, allowing decisions based on specific management zones, localized application of nutrients and decompaction, and recovery of areas with inefficient management.

“…The kurtosis values should be preferentially zero. However, values ranging from +2 to -2 are accepted, although they may indicate that the data are not normally distributed (OLIVEIRA et al, 2021). In area-1, at the 0-0.20 m depth, P and K showed kurtosis above +2, whereas, for 0.20-0.40 m, P, K, Mg, and Al were higher than +2.…”

“…In Bahia, where a tropical climate predominates, banana cultivation requires supplementary irrigation since evapotranspiration is higher than precipitation (OLIVEIRA et al, 2021). In addition, the rapid annual growth of banana demands signifi cant soil nutrient levels, with fertigation emerging as a viable tool to supply the nutrient demands of this crop.…”

Banana production requires strategies to assess the variability of fertigation areas since production can be reduced by consecutive cultivation in chemically-restricted soils and at different elevations. From this perspective, this study aimed to investigate the spatial variability of soil chemical attributes and the soil carbon stock and relate these parameters to the elevation of a banana plantation fertigated by a micro-sprinkler system. The study was conducted at the Irrigation Perimeter Nupeba (Riachão das Neves/BA), in an area cultivated with the banana cultivar Prata for 18 years. In April 2017, single soil samples were collected in an area with a minimum elevation of 440.6 m and a maximum of 445.8 m, at the depths of 0-0.20 m and 0.20-0.40 m, with a sampling grid composed of 40 georeferenced points and spaced 10 meters. The following parameters were determined: pH, total organic carbon (COT), soil organic matter (OM), nitrogen (N), phosphorus (P), potassium (K + ), calcium (Ca 2+ ), magnesium (Mg 2+ ), aluminum (Al 3+ ), potential acidity (H+Al), sum of bases (SB), cation exchange capacity (CEC), base saturation (V%), and carbon stock (Est C). The data were evaluated by descriptive statistics and geostatistics and showed normal distribution. There was spatial variability, allowing the construction of fertility maps. The maps showed that the elevation especially infl uences the OM, COT, N, and Est C, also showing the distribution and concentration of nutrients in the soil, allowing to minimize the variability through the application of varied nutrient contents aiming at their homogeneous supply to banana plants.

“…A análise dos dados mostrou forte dependência para os atributos químicos do solo (GDE < 25%) e moderado para produtividade (25% < GDE ≤ 75%). O forte GDE, indica que o modelo foi capaz de detectar a variabilidade existente no local, sugerindo que os atributos do solo não estão dispostos no espaço de forma aleatória e que esses atributos são influenciados por fatores intrínsecos do solo, como material de origem, mineralogia, relevo, organismos e tempo (OLIVEIRA, et al, 2021;VOGADO et al, 2020) alterando-se menos com os valores extrínsecos, tais como, adubação e correção, que por sua vez não influenciam as respostas do variogramas (Aquino et al, 2014).…”

“…Os locais que apresentam maior capacidade de acidificação, tendem a se correlacionar com as áreas de maior concentração de carbono orgânica (Santana et al, 2019); é possível ser observado na tabela 5 a correlação positiva entre H+Al e COT. Valores tidos como médios (2.51 -5.00 cmolc dm -3 ) (Tabela 3), indicam que a área cultivada não apresenta toxicidade, assim, não prejudicando o desenvolvimento do sistema radicular (Oliveira et al, 2021).…”

As pastagens contribuem de maneira significativamente para os meios de subsistência e serviços ecossistêmicos e são consideradas como principal fonte de fibra e nutrientes animal. Este trabalho teve como objetivo avaliar a variabilidade espacial dos teores de cálcio, alumínio, acidez potencial, fósforo e carbono orgânico total, bem como sua correlação com a produtividade de uma pastagem de capim Mombaça em um Neossolo Litólico Distrófico no município de Floriano-PI. O trabalho foi realizado na fazenda experimental do Colégio Técnico de Floriano (CTF), pertencente à Universidade Federal do Piauí. A área avaliada corresponde a 2 ha cultivada com capim Mombaça (Panicum Maximum cv. Mombaça) irrigado com sistema de aspersão. A amostragem do solo foi realizada nos pontos de cruzamento de uma malha, com intervalos regulares de 10 metros em uma área de 0,54 ha, perfazendo o total de 54 pontos amostrais. Para análise dos dados foram utilizados os métodos da estatística clássica, análise de correlação, análise geoestatística e técnica de interpolação de dados. O diagnóstico da fertilidade do solo mostra o fósforo como o mais deficiente seguido do cálcio. Os valores de alumínio e acidez potencial mostram-se adequados ao bom desenvolvimento do capim Mombaça. A variabilidade dos mapas mostra a heterogeneidade da distribuição e concentração dos elementos no solo, o que possibilita a aplicação de fertilizantes em taxas variadas visando sua homogeneização. A produtividade teve forte relação com os teores cálcio e fósforo. O uso da geoestatísticas podem ser usadas para otimizar áreas de produção capim Mombaça em Neossolos Litólicos.
