composed of 3 other operations: furrow opening with fertilizer distribution, manual seedling, and closing of the furrow wit micronutrients supply. This resulted in general in 5 pass of the tractor in the PZ zone. It is important to observe that the planting operation was conducted using autopilot system, and rows were spaced 1.5m. In TPSD zone the traffic of 2 tractors, 2 trucks and a hydraulic winch for distribution of “seedcane” were added, and there was no traffic logistical control of the machines and equipment at this stage. Data were collected using an automatic penetrometer equipped with electric motor and speed control for constant penetration rate, with data acquisition system (PLG5200- SoloTrack, Falker ©, Porto Alegre-RS). Using a cone type 2 with 129 mm 2 circular based according to ASABE Standard S313.3 (ASAE, 2009) and the values of penetration resistance were collected up to of 600mm depth. 30 points with 3 repetitions were allocated in regular intervals of 50 m (grid 50 x 50 m), 90 observations at all. The location of sampling points was made with the support of the receptor GPS GeoExplorer 3 (Trimble© Navigation). Data of penetration resistance were collected in two different occasions, before soil tillage (90 observations) in December 2010 and two treatments were evaluated after the planting in semi-mechanized TPSD zones (45 observations) and the PZ zones (45 observations) in May 2011. The operation of furrow opening and demarcation of the two treatments was made by a two lines plow-fertilizer attached to an agricultural tractor (BH205I, Valtra Corporation, São Paulo), equipped with an autopilot system (System 150, Topcon© Positioning Systems). Figure 1 shows the lines of TPSD zones and PZ zones and identifies the points of data collection. The depth tracks are divided into 6 soil layers with 100 mm each. Where in each layer was determined the maximum value of resistance to penetration. An analysis of variance and mean comparison between treatments, and ranges in depth using the Duncan test (p
3. Results and discussions Table 1 shows the water content in soil and number of observations of resistance to penetration and location where they were taken. The wet soil due to rainy season favored the collection of data and 90 observations have records of resistance to penetration to a depth of 600 mm. However, data collection after planting at some points did not reach a depth of 600 mm and was considered incomplete observations. It can be seen in Table 1 that after planting soil water content in was on average 34% lower than in the data collected before soil tillage operations. This reduction in soil water increased resistance to penetration, without necessarily increasing the compaction, but resulting in more than 45% of the number of incomplete data, and in some cases the penetration depth of the equipment could not exceed 100 mm because the high resistance to penetration of the soil.
