Resumo: | Phosphorus (P) acts on the energy metabolism of plants and in most Brazilian soils its availability is low, and phosphate solubilizing microorganisms (MSP) are promising in the availability of P to plants, through the availability of insoluble phosphates. Also, the spatial variability of P can be estimated through precision agriculture and generate management zones for its availability. The work was carried out in the municipality of Dom Pedrito-RS, in an experimental area of 5.7 ha-¹ . The determination of the spatial variability of the P content in the soil was measured in a regular sampling grid with 40 points, from the layer 0 to 20 cm. The detection of spatial variability, geostatistical modeling, preparation of the thematic map of P content and generation of P management zones were performed using the QGIS software version 3.16, using the Smart Map plugin. The cultivar used was BMX Zeus Ipro with 18 seeds m-¹ , spaced 50 cm-¹ . The phosphorus solubilizer contained strains B119 (Bacillus megaterium) and B2084 (Bacillus subtilis) with 4x109 viable cells per ml of product, applied via directed jet in the sowing furrow at a dose of 200 ml-¹ of commercial product ha-¹ and flow of 20 liters ha-¹ . The soluble mineral source was applied to the sowing line at a dose of 80 kg ha-¹ of diphosphate pentoxide (P2O5). The experimental design was randomized blocks in a factorial scheme 2 (management zones) x 3 (sources of availability) and 4 replications. The P content in the grain (%), in the leaves (g kg-¹ dry matter) and in the soil (mg dm-¹ ), the weight of a thousand grains (g-¹ ) and the productivity (kg ha-¹ ). The thousand-grain mass increased by 5.84% with the solubilizer and 4.79% with the mineral P source. The P content in the grain was 5.55% higher with the mineral source, compared to the control, not differing from the levels observed for the solubilizer. The supply of P via mineral source resulted in higher P content in the soil after the soybean harvest. Productivity was higher with the mineral source and solubilizer, compared to the control. Management zones with higher P availability showed productivity 9.44% above the ZM with lower availability. The P content in the grains was higher in ZM with lower P availability. Yield is responsive to the addition of P in areas of lower availability, with an increase of 8.51% via solubilizer and 11.57% via mineral source, compared to the nonaddition of the nutrient. The delimitation of ZM, based on the availability of P in the soil, indicated a reduction in the cost of supplying P, either via mineral source or solubilizer. The P solubilizer was able to supply the soybean demand and can replace the mineral source when the P contents in the soil are above the lower limit of the average interpretation class. |

Também, a variabilidade espacial do P consegue ser estimada através da agricultura de precisão e gerar zonas de manejo de sua disponibilidade. O trabalho foi conduzido no município de Dom Pedrito-RS, em área experimental de 5,7 ha-¹. A determinação da variabilidade espacial do teor de P no solo foi medida em grade amostral regular com 40 pontos, da camada 0 a 20 cm. A detecção da variabilidade espacial, modelagem geoestatística, confecção do mapa temático do teor de P e geração de zonas de manejo de P se deram através do software QGIS versão 3.16, com uso do plugin Smart Map. A cultivar utilizada foi a BMX Zeus Ipro com 18 sementes m-¹ , espaçada 50 cm-¹. O solubilizador de fósforo continha as cepas B119 (Bacillus megaterium) e B2084 (Bacillus subtilis) com 4x109 células viáveis por ml de produto, aplicado via jato dirigido no sulco de semeadura na dose de 200 ml-¹ de produto comercial ha-¹ e vazão de 20 litros ha-¹ . A fonte mineral solúvel foi aplicada na linha de semeadura em dose de 80 kg ha-¹ de pentóxido de difosfato (P2O5).O delineamento experimental foi de blocos ao acaso em esquema fatorial 2 (zonas de manejo) x 3 (fontes de disponibilidade) e 4 repetições. Mensurou-se o teor de P no grão (%), nas folhas (g kg-¹ matéria seca) e no solo (mg dm-³), a massa de mil grãos (g-¹ ) e a produtividade (kg ha-¹ ). A massa de mil grãos aumentou em 5,84% com solubilizador e 4,79% com a fonte de P mineral. O teor de P no grão foi 5,55% maior com a fonte mineral, comparado a testemunha, não diferindo dos teores observados para o solubilizador. O fornecimento de P via fonte mineral resultou em maior teor de P no solo após a colheita da soja. A produtividade foi maior com a fonte mineral e solubilizador, comparada à testemunha. Zonas de manejo de maior disponibilidade de P apresentaram produtividade 9,44% acima da ZM de menor disponibilidade. O teor de P nos grãos foi maior em ZM de menor disponibilidade de P. A produtividade é responsiva a adição de P em zonas de menor disponibilidade, com aumento de 8,51% via solubilizador e 11,57% via fonte mineral, em relação a não adição do nutriente. A delimitação de ZM, com base na disponibilidade de P no solo indicou redução no custo com fornecimento de P, seja via fonte mineral ou solubilizador. O solubilizador de P consegiu suprir a demanda da soja e pode substituir a fonte mineral quando os teores de P no solo se encontram acima do limite inferior da classe de interpretação médio.porUniversidade Federal de Santa MariaColégio Politécnico da UFSMPrograma de Pós-Graduação em Agricultura de PrecisãoUFSMBrasilAgronomiaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessFósforoGeoestatísticaBacillus sp.MicroorganismosAgricultura de precisãoPhosphorusGeostatisticsMicroorganismsPrecision agricultureCNPQ::CIENCIAS AGRARIAS::AGRONOMIAZonas de manejo do teor de fósforo (P) e resposta da soja inoculada com solubilizador de fosfatoPhosphorus (P) content management zones and response of soybean inoculated with phosphate solubilizerinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBottega, Eduardo Leonelhttp://lattes.cnpq.br/2754758384879917Oliveira, Zanandra Boff dePes, Luciano ZucuniKnies, Alberto Eduardohttp://lattes.cnpq.br/8927181716477028Guesser, Vagner Portes5001000000096006006006006006003cb47b1a-7e02-477e-8587-da1cac13b7f7fb456040-5192-44fa-b9fb-b7dffebdea743b9eb7ee-7080-417f-972a-99806645b6c12597a15a-ae4e-43cc-b1fd-a0a59bfe6fa90deab9d5-36a9-4609-a59c-8def0de1a5acreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGAP_2022_GUESSER_VAGNER.pdfDIS_PPGAP_2022_GUESSER_VAGNER.pdfDissertação de Mestradoapplication/pdf1265365http://repositorio.ufsm.br/bitstream/1/26219/1/DIS_PPGAP_2022_GUESSER_VAGNER.pdf301b126e28bfde1a9ecadb417a3e5079MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8805http://repositorio.ufsm.br/bitstream/1/26219/2/license_rdf4460e5956bc1d1639be9ae6146a50347MD52LICENSElicense.txtlicense.txttext/plain; charset=utf-81956http://repositorio.ufsm.br/bitstream/1/26219/3/license.txt2f0571ecee68693bd5cd3f17c1e075dfMD531/262192022-09-21 10:08:01.98oai:repositorio.ufsm.br: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 Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-09-21T13:08:01Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |
