“…In this context, due to the concern that encompasses environmental preservation and increase in production cost, soil remineralizers have been studied as an alternative source of nutrients (RAMOS et al, 2017;ZHANG et al, 2018;AGUILERA et al, 2020;SILVA et al, 2020, ALMEIDA et al, 2022. Remineralizers are agricultural inputs (BRASIL, 2013;2016) capable of improving the physical-chemical properties of the soil through the release of macro Contribuciones a Las Ciencias Sociales, São José dos Pinhais, v.16, n.1, p.460-478, 2023 jan. 2021 and micronutrients (RAMOS et al, 2017;BRITO et al, 2019;ALOVISI et al, 2020) alternative to chemical fertilizers. However, their large-scale use in agriculture faces great challenges due to the difficult solubilization (WHITE et al, 2017) and low content of soluble nutrients (COLA & SIMÃO, 2012) when compared to chemical fertilizers, generating controversies regarding their ability to minimize the cost of production while maintaining crop yield.…”

Agriculture is characterized by the high use of fertilizers to promote higher income expectations and, due to the representativeness of this input, the cost of agricultural production is strongly affected. The present study aims to evaluate the economic efficiency of the association of olivine melilitite powder with beneficial microorganisms and the reduction of 25% chemical fertilization in maize cultivation. Five treatments were tested under a randomized block design with four replicates, represented by the application of the remineralizer associated with inoculation of bacteria of the genera Bacillus spp. and Azospirillum spp. with a 25% reduction in the recommended basal fertilization, plus fertilization with only formulated fertilizer as control treatment. The economic technical coefficients were evaluated: Gross Revenue (GR), Operating Profit (OP), Total Operating Cost (TOC), Leveling Point (LP), Profitability Index (PI) and Yield (YLD). Application of remineralizer associated with inoculation of bacterial strains of the genera Bacillus spp. and Azospirillum spp. showed the best economic indicators, promoting increments of up to 7% in PI and 15% in OP, and grain yield remained at high levels. However, application of remineralizer without inoculation of microorganisms negatively impacted grain yield, reducing PI, OP and GR. Pearson’s coefficients indicate a strong relationship of the YLD variable with PI and OP, enabling the application of olivine melilitite powder as an alternative source of nutrients in the cultivation of off-season maize. It is concluded that the application of olivine melilitite powder is economically viable and increases the profitability index, while keeping maize yield at high levels when associated with inoculation of bacteria of the genera Bacillus spp. and Azospirillum spp.

“…Segundo Alovisi et al (2020), o pó de basalto pode ser considerado como uma fonte alternativa de fertilizante e corretivo do solo de baixo custo, entretanto, a baixa solubilidade do pó de basalto indica que tal material não pode ser utilizado como a principal fonte de nutrientes às plantas.…”

Objetivou-se com o presente estudo avaliar o efeito residual da adição de pó de rocha basáltica associado ou não a adubação química, sobre os atributos químicos do solo e produtividade da cultura da soja. O delineamento experimental foi de blocos casualizados em esquema fatorial (5x2), testando, cinco doses de pó de rocha (0; 2,5; 5,0; 7,5 e 10,0 Mg ha-1), com ou sem adubação química de NPK na formulação 05-25-06, com quatro repetições. O experimento foi conduzido em condições de campo. Foram avaliadas as características agronômicas de altura final de plantas, altura da inserção do primeiro legume, diâmetro do coleto, peso de 1000 grãos, produtividade da soja e os atributos químicos do solo. A adubação química influenciou os teores dos nutrientes P, K e Mn no solo. Na camada de 0-10 cm houve aumento dos teores de P e K. Na camada de 10-20 cm ocasionou redução no teor de Mn. O residual da aplicação das doses de pó de basalto ocasionou a redução das concentrações foliares de P, Cu, Zn. A adubação química complementar favoreceu a redução da concentração do Mg foliar. Altura de plantas, diâmetro do coleto, peso de grãos e produtividade foram maiores nos tratamentos que receberam a adubação química. A pequena liberação dos nutrientes do pó de basalto indica que tal material não pode ser utilizado como a principal fonte de nutrientes às plantas.

“…In this context, a greater number of research related to the use of rock powders has been realized, with the objective to evaluate the ability of these sources to substitute or complement other soluble and/or organic sources. According to Theodoro et al (2012) and Alovisi et al (2020), the rock powder application can be easily adopted by family farmers, due to its simplicity, low cost of use and positive results in terms of grain yield. However, the main limitation is the slow solubilization and release of nutrients to the plants, with a source being less responsive when compared to short-term soluble mineral sources (Ferreira, Almeida, Mafra & 2009;Hanish et al, 2013;Gotz et al, 2019;Gotz, Piovesan & Castamann, 2020;Alovisi et al, 2020).…”

The aim of this study was to evaluate the efficiency of rock powder applied isolated or associated with egg-laying hen manure as a source of nutrients for maize crop; and to evaluate the effect of application form in the efficiency of this sources in improve crop yield. The experiment was composed by eight treatments, distributed in a randomized block design and in factorial design 4 (A) x 2 (B), with four replicates. In factor A, the different sources of nutrients were allocated: rock powder; rock powder + egg-laying hen manure; egg-laying hen manure; and control; applied on the soil surface or incorporated with harrow. The doses used were 2 and 10 Mg ha-1 of rock powder and manure, respectively. Were evaluated: foliar nitrogen (N) and phosphorus (P) contents; extraction of N and P; and maize yield components. There was no interaction between the factors tested. The use of egg-laying hen manure isolated or associated with rock powder resulted in higher foliar P content, higher P extraction and increase in maize yield components, except for the number of plants per linear meter and cobs per plant. The application form did not affect the maize yield components, but when applied on the surface it increased foliar P content and P extraction. Rock powder is efficient in promoting better maize yield only when associated with manure. The incorporation of rock powder does not increase its efficiency in providing nutrients to the plants.
