Compressibility of a Cambisol Submitted to Periods of Rotational Grazing and Strategies to Avoid Additional Soil Compaction

“…Based on Pimentel-Gomes and Garcia [49], the coefficient of variation was high (between 20 and 30%) and very high (larger than 30%) for two-times grazing and low (smaller than 10%) and medium (between 10 and 20%) for three-times grazing (Table 2). Soil moisture is an important variable in the compaction process and soil compression behavior [23,24,[27][28][29][30][31], because it acts as a lubricant for solid particles, belonging to the easier rearrangement of soil particles [26,50], suggesting that controlling soil moisture is a key factor in mechanized operations and animal trampling [24,51] to avoid additional compaction and maintain the soil structure.…”

“…From the knowledge of the precompression stress and compression index, and their existing relationship with moisture and bulk density [23,24,[26][27][28][29][30][31], the soil and the traffic of machinery and animals trampling can be managed in order to avoid additional compaction. Soil bulk density is a good indicator of compaction [8], and some authors have verified a relationship between precompression stress and/or compression index with bulk density [23,24,26,29,32,33].…”
