Abstract

Soil penetration resistance is an important indicator of soil compaction. Knowing the precise location of layers with increased resistance to penetration can aid in the mechanical management of soil. In this context, the objective of this study was to analyze the soil penetration resistance of a Dystroferric Red Latosol, under no-tillage system with additional compaction due to tractor traffic, using multivariate factor analysis. Compaction states were induced with tractor traffic in a no-tillage area in 0, 2, 4, 6, 8, and 12 passes of an agricultural tractor. The tractor used was the NH 8030 model, with an engine power of 89.79 kW (122 hp). It had diagonal tire wheels with an inflation pressure of 83 kPa on the front tires (14.9-28 R1) and 83 kPa on the rear tires (23.1-30 R1). Additionally, a mass of 7.28 Mg was applied to the soil with each tractor pass. An electronic penetrometer was used to evaluate the soil resistance, with 10 points being taken in each experimental plot. Simultaneously, deformed structure samples were collected to determine soil moisture. Multivariate factor analysis was used as a tool to analyze soil penetration resistance, seeking to determine its stratification up to 0.40 m depth. Factor analysis applied to the study of soil with different tractor traffic intensities allows the identification of layers of growth, transition, reduction, and stabilization of soil resistance to penetration at depth. Soil layers associated with management with furrows in previous crops were identified, as well as compacted surface soil layers induced by tractor traffic compaction, in addition to layers with stabilization at depth, possibly associated with pedogenetic factors.

Abstract

The objective of this work was to evaluate the soil physical attributes and their relationship to soybean productivity under no-tillage system. The study was conducted in a Oxisol, based on randomized blocks design, with the treatments: no-tillage for 10 years (0 tractor traffic) and five tractor-traffic intensities (2, 4, 6, 8, and 12 passes), with five repetitions. An increase of macroporosity up to 10% under soil bulk density ranging from 1.51 to 1.56 mg.m-3 and soil penetration resistance between 1.5 to 2.0 MPa, on the 0.00-0.10 m layer benefited the soybean productivity. The number of pods per plant, grain number per plant, stem diameter, and soybean productivity is higher in Oxisol, under intermediate compression. Soil bulk density and soil penetration resistance showed to be sensitive an indicators of soil physical quality, with more relation to soybean grain productivity.
