“…Also, is important to mention that as observed by Zhang et al, (2023), organic matter in the soil promoted growth in teak and these species tend to improve general OM in the soil since the rate of decomposition of teak litter in tropical soils is slow because of the higher content of insoluble lignin (Cavalcante et al, 2021). In general, organic matter in the soil has great importance in teak growth, since the volume of production is directly linked to this variable (Neto et al, 2020) and this phenomenon has also been observed in Eucalyptus trees (Barry et al, 2015). Other trees species increase their productivity as well, using organic fertilizers for nutrients in comparison to inorganic fertilizers such as yellow poplar tulipifera Lin.)…”

Peru has a great potential for forestry plantations, nevertheless, importations of this type of products are getting very expensive. Soils under forest are acidic and infertile to support sustainable economically valuable forest tree species such as teak. Information is lacking on proper fertility management in forest plantations such as teak. Therefore, the objective of this study was to explore the effect of lime, and organic and inorganic fertilizers on the early growth and nutrient composition of 12-month old teak grown on acidic soil of Peru. The soil under field study was acidic with a pH of 4.99, low in fertility. A factorial design of 2x3: Lime (No Lime and Liming) and fertilizer (organic, inorganic and mixture), with 9 repetitions was adopted. Tree biometric parameters (height, diameter, biomass) and N, P, K, Ca, Mg, Fe, Cu, Mn, Zn foliar concentrations were determined during early the growth of teak. Treatments with addition of dolomite lime favored higher biometric parameters, and use of organic fertilizers promoted more growth than inorganic fertilizers. In the case of nutrients, no major differences were observed between limed and unlimed treatments while organic fertilizer promoted Ca, K and S nutrition. The results show that the application of lime and organic fertilizers is essential for the successful management and establishment of teak plants in acidic soils of Peru.

“…A maioria das variáveis (Mg, Al, H+Al, P e PF) ajustaram-se ao modelo exponencial, comumente encontrados na representação dos atributos do solo nas camadas superficiais (Aquino et al, 2014;Negreiros Neto et al, 2014;Santana da Silva Carneiro et al, 2016). Macedo Neto et al, (2020), destacaram que os modelos exponencial e gaussiano se ajustam com maior frequência para as variáveis de fertilidade do solo e apresentam coeficiente de determinação do modelo (R 2 ) com valores altos, corroborando com os resultados encontrados nesse trabalho.…”

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.

“…Additionally, soil attributes can vary spatially on a reduced geographic scale due to management factors, e.g., fertigation and crop rotation (SILVA et al, 2018). Therefore, the analysis of the spatial variability of soil chemical attributes in the planting area is important to provide appropriate fertility management, allowing the localized application of nutrients in defi cient places (MACEDO NETO et al, 2020;MATIAS et al, 2015).…”

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.
