“…This result agree with those quoted by Botta et al (2002). For the 200-400 mm depth range, Figure 1 and Table 5 show that the HT caused higher BD and CI values than the LT. From this, it can be inferred that after a depth of 200 mm, tractor load was responsible for subsoil compaction, as demonstrated by Håkansson and Reeder (1994).…”

“…The behaviour of soil in this freshly tilled horizon following traffic agrees with results quoted by Smith and Dickson (1990) and Botta et al (2002Botta et al ( , 2006, confirming the direct relationship between topsoil compaction and ground pressure. Also, when soils are dryer, like in this case, the water potential is lower, and narrower tyres will cause more soil compaction than wider tyres (Greene and Stuart, 1985).…”

“…In contrast, wheel load have a very large influence on subsoil stresses. Botta et al (2002) considered that it is advisable to divide soil compaction into two different problems: i) topsoil compaction, within range of depth corresponding to the cultivated horizon (Ap), and ii) subsoil compaction, appearing at depths below the Ap depth limit. Håkansson and Reader (1994), who stated that when subsoil compaction is induced below the Ap horizon, mechanical loosening to alleviate this compaction is very difficult, always expensive and eventually impossible.…”

The general objective of this paper was to quantify the changes in the physical properties of an Aridisol soil and the effect on wheat yield due to agricultural tractors traffic in the Vélez Blanco District, Almería Spain. Parameters measured were cone index (CI) in the 0-600 mm depth profile, bulk density (BD) and rut depth; the variable wheat yields (WY) was measured too. The traffic treatments applied were: 0 (control plot), 1, 3, 5, and 7 tractor passes in the same tracks. Each experimental plot was trafficked with two tractors, one light (60 kN) and one heavy (80 kN). In topsoil (0-200 mm), up to five passes of the heavy (HT) and light tractors (LT), as in one and three passes, the BD and CI values responded to the ground pressure being higher in absolute value for LT. For the 200 to 400 mm depth range HT caused higher CI (1,570 to 2,200 kPa) and BD (1.38 to 1.68 Mg m -3 ) values than LT. Eight months later, WY was evaluated in tractor's track areas and decreases in the range of 18-38%, were measured. For seven passes the applications of total loads of 80 and 60 kN increased BD up to 1.5 Mg m -3 at depths of 200-600 mm. Although soil had high bulk density prior to traffic treatments, a significant increment of subsoil compaction still occurred due to the high traffic intensities applied.Additional key words: axle load; bulk density; cone index; rut depth. ResumenEfectos del tráfico del tractor sobre la distribución de la compactación del suelo y los rendimientos de trigo en EspañaEl objetivo general del estudio fue cuantificar los cambios producidos en las propiedades físicas de un suelo Aridisol y los efectos sobre el rendimiento del trigo debido al tráfico de tractores agrícolas en Vélez Blanco, Almería, España. Los parámetros analizados fueron índice de cono (IC) a una profundidad de 0-600 mm, densidad aparente (DA) y profundidad de huella; también se analizó la variable rendimiento del trigo (RT). Los tratamientos de tráfico aplicados fueron: cero (parcela testigo), y uno, tres, cinco, y siete pasadas de tractor sobre la misma huella. En cada parcela experimental se utilizaron dos tractores, uno ligero (60 kN) y uno pesado (80 kN). En el horizonte superficial (0-200 mm), hasta las cinco pasadas de los tractores pesados (TP) y ligeros (TL), los valores de DA y de IC respondieron a la presión en el área de contacto, siendo más alto en valor absoluto para TL cuando pasó una y tres veces. Para el rango de profundidad 200-400 mm, TP causó valores más altos de IC (1.570 a 2.200 kPa) y DA (1,38 a 1,68 Mg m -3 ) que TL. RT se evaluó ocho meses después sobre el área pisada, observándose una disminución en un rango de 18-38%. Las cargas totales aplicadas de 80 y 60 kN, con siete pasadas, aumentaron DA hasta 1,5 Mg m -3 en el rango 200-600 mm. A pesar de que el suelo presentó una alta DA antes de aplicar los tratamientos, se observó un incremento significativo de la compactación del subsuelo por las altas intensidades de tráfico aplicadas.Palabras clave adicionales: carga en el eje; índice de cono; profund...

“…A resistência mecânica do solo à penetração é considerada como o parâmetro do solo mais sensível na detecção do efeito da compactação (Jorajuria & Draghi, 2000, Botta et al, 2002, Streck et al, 2004e Collares et al, 2006. Assim, pode-se utilizar esse parâmetro no planejamento do tráfego de máquinas agrícolas, para evitar a compressão excessiva ao solo, desde que ela seja analisada em conjunto com os dados de teor de umidade do solo.…”

O objetivo deste trabalho foi avaliar o efeito da intensidade de tráfego e do sistema de manejo na demandade tração de umahaste sulcadora deadubo,e naspropriedadesfísicas de umArgissoloVermelho-Amarelo. Os tratamentos foram: semeadura direta com tráfego natural, semeadura direta com tráfego adicional de intensidade de 24,79 Mg km ha-1, semeadura direta com tráfego adicional de intensidade de 49,59 Mg km ha-1, cultivo mínimo e cultivo mínimo em solo compactado com tráfego de 24,67 Mg km ha-1. Foram coletados dados de: porosidade total; densidade do solo; resistência mecânica do solo à penetração; e de esforço horizontal, vertical e de tração da haste sulcadora de adubo da semeadora. A subsolagem do cultivo mínimo, utilizada como técnica isolada, não reduziu os efeitos da compactação ocasionados pela intensidade de tráfego de 24,67 Mg km ha-1. O tráfego afeta a estrutura do solo, sem alterar, porém, a demanda de tração. A mudança da intensidade de tráfego, de 24,79 para 49,59 Mg km ha-1, não ocasionou maiores alterações nas propriedades avaliadas.

“…Multiple passes of a light tractor can do greater damage than passes of a heavier tractor with fewer passes. The critical number of passes was ten, beyond which advantages from the use of a light tractor were lost (Botta et al 2002). However, the first pass of a wheel is known to cause a major portion of the total soil compaction (Bakker and Davis 1995).…”

summarize the following general benefits from the use of guidance systems: reduction in driver fatigue, reduction in costs, increase in productivity, improved work quality, improved safety, less impact on the environment, possibility for work at night and when visibility is poor.Many different types of guidance systems such as ground-based sensing systems, laser systems, Machinery guidance systems analysis concerning pass-to-pass accuracy as a tool for efficient plant production in fields and for soil damage reduction Z. Kvíz, M. Kroulik, J. Chyba Department of Agricultural Machines, Faculty of Engineering, Czech University of Life Sciences Prague, Prague, Czech Republic ABSTRACTMachines without satellite navigation in fields have a tendency to pass-to-pass errors, especially unwanted overlaps, resulting in waste of fuel and pesticides, longer working times and also environmental damage. This paper evaluates the accuracy of individual machinery passes in fields. Real pass-to-pass errors (omissions and overlaps) in a field were measured on different tractor-implement units with and without guidance system utilization and a comparison between observed guidance arrangements was made regarding final working accuracy and possible benefits from navigation utilization. Additionally, intensity of machinery passes, and repeated passes on soil, as a possible risk for soil compaction in fields, were monitored. The outcomes from our measurements revealed a statistically significant difference between the total area treated by machinery without any guidance system and machinery using precise guidance systems. Concerning the intensity of traffic in fields, it was found out that more than 86% of the total field area was run-over at least once during one cropping season when using conventional tillage practice. The usage of guidance systems can reduce machinery traffic in field to some extent as well and thus improve soil conditions.
