“…However, the application of the same quantities of P in the form of HP did not result in the same increase in the soil available P (Figure 1). As a consequence, there was not adequate P nutrition of the natural grassland (Figure 3a), even in this soil with low Ca and pH (Table 1), probably to the dominance of minerals such as apatite in the fertilizer, which has very low dissolution in soil even under acidic conditions (Somavilla et al, 2021b).…”

“…Plant diversity is often neglected when fertilization is based solely on soil analysis. In addition, the frequent use of phosphate fertilizers can favor groups of species that are more efficient in the use of nutrients and change the dynamics and diversity of the natural grasslands (Blanck et al, 2011;Ceulemans et al, 2013;Harpole et al, 2016;Somavilla et al, 2021b).…”

High acidity and low soil P availability in the soils from the Pampa natural grasslands generally limit the forage growth and economic return. Thus, to increase the economic return and avoid environmental degradation and biodiversity loss due to replacement by intensive cropping systems, it is essential to improve the soil P availability. This study aimed to diagnose the nutritional status of the pluri-specific natural grasslands amended with different history of P sources. Additionally, we also try to indicate the most appropriate range of soil P availability for maximizing forage growth. The experiment started in 1997 in an area of Pampa natural grasslands in the state of Rio Grande do Sul, Brazil. The treatments evaluated the application of Gafsa hyperphosphate (HP) and triple superphosphate (SP) for four years (1997, 1998, 2002, and 2010). Soil and aboveground biomass sampling were performed five times from October 2010 to March 2011 to access aboveground biomass production, botanical composition, soil available P, and N and P nutrition index. Greater P availability in the soil amended with SP produced more forage and resulted in a higher P accumulation than in the soil amended with HP. The ideal range of soil P availability in the soils of natural grasslands ranged from 14 to 20 mg kg ˗1 , varying for different plant species. The species Paspalum plicatulum and Aristida laevis produce less aboveground biomass and accumulate less P in their tissue than Dichantelium sabulorum and Eustachys uliginosa, and P. notatum. Therefore, areas of natural grasslands dominated by D. sabulorum, E. uliginosa and P. notatum demand higher soil P availability to maintain high forage production. Soil P fertilization of pluri-specific natural grasslands in the Brazilian Pampa biome must consider the dominant forage species in the area and the soil P availability.

“…Houve uma interação positiva entre P e produtividade, bem evidente ao observar os mapas da krigagem (Figura 2). A adubação fosfatara conforme a demanda da pastagem é necessária para manter o rendimento de matéria seca (Somavilla et al, 2021). E Magalhães et al, (2020), além de constatarem maior produção de matéria seca da parte aérea, também observaram incremento nos teores foliares de P; e que após a adubação fosfatada perceberam alteração nos valores de potássio, cálcio é magnésio do solo.…”

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.

“…In this sense, the correction of soil acidity is a major factor in increasing crop yields (SoMAVILLA et al, 2021). Lime is one of the most important agricultural inputs and has been widely used to correct surface soil acidity (LoCHoN et al, 2019).…”

“…It is also considered a great source of Ca and Mg, promoting favorable conditions for increasing the biological activity of the soil and for the development of the root system of plants (GURGEL et al, 2020). Lime is a product with relatively low cost compared to other agricultural inputs, and its benefits last for more than one crop cycle due to its low solubility (SoMAVILLA et al, 2021), making its use even more attractive to the producer.…”

Liming and biochar on sorghum growth and Arenosol chemical properties in the Semiarid environment

This research evaluated the effect of liming (with and without) and biochar (with and without) on sorghum cv. BRS Ponta Negra growth and Arenosol chemical properties in the Semiarid environment. The experimental design was in randomized blocks, with treatments in a 2x2 factorial scheme, corresponding to the application or not of lime (0 and 2.5 t ha-1) and biochar (0 and 12.5 t ha-1). Biochar was produced from cashew branches. The experiment was conducted in 16 m² plots where the forage sorghum cultivar BRS Ponta Negra was cultivated. The soil chemical characteristics, the production attributes, and the structural characteristics of the sorghum cultivar studied were evaluated. There was no interaction between factors. The use of biochar increased the pH and Ca and P contents in the soil and contributed to increasing the panicle mass (2.51 t ha-1 of DM). Lime application affected the soil Ca content as the dose of 2.5 t ha-1 resulted in higher values of culm diameter (15.25 mm), panicle mass, and culm mass (2.63 and 7.50 t ha-1 of DM, respectively). Therefore, these results allowed to outline strategies for the use of limestone and biochar for forage production in semiarid environments in sandy soils. Because, these materials improve some chemical attributes of the soil and the production of forage sorghum. It is noteworthy that edophoclimatic conditions can change the response patterns observed in this research. Therefore, research in other regions is essential.
