| description | Soil management systems have a great influence on soil physical properties and are related to soil compaction. This work aimed to evaluate the soil mechanical resistance to penetration of a dystrophic Red-Yellow Latosol (Oxisol) under different management. The experiment was carried out at Embrapa Rondônia experimental field, in Porto Velho, RO, Brazil. Samples were collected for analysis at depths from 0 to 0.05; 0.05 to 0.10; and 0.10 to 0.20 m. The penetrometers used were: an electronic model MA-933 / Marconi, and an automated field, model SOLO TRACK / Falker. The treatments consisted of the absence and addition of 2000 kg ha -1 of agricultural plaster, absence and presence of soil scarification, and three crop succession systems: SP (soybean / fallow), SMP (soybean / corn / fallow) and SMBP (soybean / maize / brachiaria / fallow). The experimental design was in randomized blocks, in a 2x2x3 factorial scheme with eight blocks. Data were subjected to analysis of variance, and when significance was found, means were compared by the Scott-Knott test at the 5% probability level. Crop succession systems can influence soil physical characteristics, the lowest PR values were observed in SMBP and SMP succession systems. The MA-933 was better to evaluate of mechanical penetration resistance. |

Assim, este trabalho teve o objetivo avaliar a resistência mecânica do solo à penetração de um Latossolo Vermelho-Amarelo distrófico sob diferentes manejos. O experimento foi desenvolvido no campo experimental da Embrapa Rondônia, no município de Porto Velho, RO, sendo coletadas amostras para as análises nas profundidades de 0 a 0,05; 0,05 a 0,10; e 0,10 a 0,20 m. Os penetrômetros utilizados foram: um eletrônico modelo MA-933/Marconi, e um automatizado de campo, modelo SOLO TRACK/Falker. Os tratamentos consistiam na ausência e adição de 2000 kg ha-1 de gesso agrícola, ausência e presença de escarificação do solo, e três sistemas de sucessão de culturas: SP (soja/pousio), SMP (soja/milho/pousio) e SMBP (soja/milho/braquiária/pousio).O delineamento experimental foi em blocos casualizados, em esquema fatorial 2x2x3 com oito blocos. Os dados foram submetidos à análise de variância, e quando constatada significância, as médias foram comparadas pelo teste de Scott-Knott ao nível de 5 % de probabilidade. Os sistemas de sucessão de culturas podem influenciar nas características físicas do solo, os menores valores de RP foram observados nos sistemas de sucessão SMBP e SMP. O penetrômetro MA-033 mostrou-se adequado para avaliação da resistência a penetração. 2020-12-24 2022-03-17T15:14:45Z 2022-03-17T15:14:45Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://www.revistas.usp.br/rdg/article/view/162486 10.11606/eISSN.2236-2878.rdg.2020.162486 http://biblioteca-repositorio.clacso.edu.ar/handle/CLACSO/42353 por https://www.revistas.usp.br/rdg/article/view/162486/166659 Copyright (c) 2020 Lucivânia Izidoro da Silva, Milton César Costa Campos, Paulo Guilherme Salvador Wadt, José Maurício da Cunha, Ivanildo Amorim de Oliveira, Ludmila de Freitas, Eduardo Antônio Neves dos Santos, Elilson Gomes de Brito Filho http://creativecommons.org/licenses/by-nc-sa/4.0/ application/pdf Universidade de São Paulo.
