“…The pressure was exerted for eight seconds, which corresponds to the time of pressure exerted by two elements of running gear of a vehicle, eg tractor wheel, which moves four times over the plot surface with the working speed of about 0.7 m s -1 (four-wheel vehicle whose wheels move in succession, with a length of single wheel contact with bedding of about 0.7 m). The number of passages of the vehicles over the plot was selected according to Kroulík et al (2009). The experiment was localized on the area of 'Kłaj' forest nursery (Niepołomice Forest District), and a fragment of nursery plot with a width of 1.2 and length of 115 m was selected for the study.…”

The paper presents the results of an analysis of the influence of soil bulk density in a forest nursery plot on the growth and quality parameters of Scots pine and European beech seedlings. Particular density variants were obtained using a tractor device exerting controlled pressure on the soil, while field examinations were performed on an area of ‘Kłaj’ forest nursery in Niepołomice Forest District. Three series of plots were prepared for each species, applying a unit pressure of the values of 50, 100, 150, 200, 250 kPa, corresponding to the dry bulk density in the range of 1.03-1.19 g cm-3, and control plots without the pressure. Seeds of the examined species were sown on the prepared plots, and after 6 months of growth the seedlings were subjected to biometric analysis determining differentiation in root neck diameter, length of the above-ground part and root system, as well as dry mass of particular parts of the plant. The quality of the seedlings was also determined using the method of Schmidt-Vogt. The results obtained show that the change in dry bulk density soil significantly affected most of the growth parameters of the examined seedlings. Especially high negative correlations were obtained for the length and dry mass of the root system. A significant influence of dry bulk density variant on all growth parameters of Scots pine seedlings, and on some parameters of European beech was demonstrated. An increase in soil bulk density clearly caused also a deterioration of European beech seedlings quality

“…Considerando-se que o solo deste estudo vinha sendo cultivado com lavoura anual em SPD, há mais de dez anos, e que os tratores agrícolas e colhedoras, em geral, produzem cargas superficiais entre 100 e 200 kPa (Carpenedo, 1994) e, ainda, que a área efetivamente trafegada pode chegar a 56 e 95% em um único ano agrícola, respectivamente, para plantios direto e convencional (Kroulik et al, 2009), é muito provável que a pressão exercida pelas patas dos caprinos tenha sido inferior à pressão de pré-consolidação do solo da área experimental. Por isso, não seria esperado observar alteração significativa da densidade e da porosidade do solo.…”

Alexandergrass sward height management and properties of soil in crop-livestock systemIn southern Brazil there is spontaneous occurrence of alexandergrass (Urochloa plantaginea (Link) R.D. Webster) in crops during summer, and this plant has great potential forage production. The objective of this study was to evaluate the changes in physical characteristics and soil organic matter in pastures of Alexandergrass with different sward heights, in the presence and absence of animal trampling. The experiment was conducted at the Experimental Station IAPAR, in Pato Branco. The experimental design was randomized blocks with three replications. The treatments were arranged in a split-plot factorial model during the grazing period. The plots consisted of levels of the factor height of pasture management (0.1, 0.2, 0.3 and 0.4 m), while the subplots consisted of areas with (grazed by goats) and No sul do Brasil, há ocorrência espontânea de papuã (Urochloa plantaginea (Link) R.D. Webster), nas lavouras, no período de verão, sendo que essa planta possui grande potencial forrageiro. Neste trabalho, objetivou-se avaliar as alterações ocorridas nas características físicas e na matéria orgânica do solo, em pasto de papuã, com diferentes alturas de manejo, na presença e na ausência de pisoteio animal. O trabalho foi realizado na Estação Experimental do IAPAR, no município de Pato Branco, Paraná. O delineamento experimental utilizado foi o de blocos casualizados com três repetições. Os tratamentos foram arranjados em esquema bifatorial, com parcelas subdivididas, durante o período de pastejo. As parcelas receberam os níveis do fator altura de manejo de pasto de papuã (0,1; 0,2; 0,3 e 0,4 m), enquanto as subparcelas foram constituídas de áreas com (pastejadas por cabras) e sem pisoteio animal (corte manual). Foram avaliados, após o período de pastejo, os teores de matéria orgânica, a densidade, a porosidade total, a macro e a microporosidades do solo. De maneira geral, a altura de manejo do papuã, na presença, ou não, de pisoteio animal, não alterou significativamente as características físicas e a matéria orgânica do solo, avaliadas após o primeiro ciclo de aplicação dos tratamentos. O pisoteio animal não causou compactação adicional e, mesmo com pastejo animal, os teores de matéria orgânica no solo mantiveram-se altos.Palavras-chave: plantio direto, manejo do solo, cobertura do solo, matéria orgânica do solo.

“…as "random traffic" or RTF). Treatment D was also considered to be representative of conservation tillage and RTF in the region based on the work of Kroulík et al (2009). The experimental approach was based on that adopted by Galambošová et al (2010) and Smith et al (2014) for simulating the effects of random traffic patterns on crop and soil.…”

“…In well-designed CTF systems, the permanent traffic lanes typically occupy less than 20% of the total cultivated area (Tullberg, 2010). Without CTF, unmatched equipment operations and track widths translate into disorganized or unconstrained traffic patterns, which can cover 85% or more of the total cultivated area each time a crop is produced (Kroulík et al, 2009;Tullberg, 2010). Research has shown that CTF has fundamental advantages in maintaining soil structural conditions, with lower inputs of energy (reduced draft) and improved trafficability and timeliness, compared to conventional traffic systems (Chamen and Longstaff, 1995;Tullberg, 2000;McPhee et al, 2015).…”
