“…These results indicate that the yield of these crops in succession to forage is not affected when moderate grazing pressure is used, which is in agreement with the results obtained by Lunardi et al (2008), Balbinot Junior et al (2011 and Moraes et al (2011). Additionally, the present study's results demonstrate that the time between when the grazing is stopped and the sowing of summer crops occurs does not have much relevance when the forage is maintained at an appropriately high level during the grazing period, as discussed by Balbinot Junior et al (2009).…”

The use of cropland to grow annual winter forages that are managed using direct grazing can affect the quality of the soil and the yield of summer crops grown in succession. This study aimed to evaluate the effect that the form of sowing (direct sowing and sowing + harrowing), the deferral intervals (ungrazed and grazing stopped at 14 days and 28 days before and on the day of forage desiccation) and the fertilisation of the annual winter forage (with and without application of 8 m 3 ha -1 of poultry litter) had on the chemical properties of soil, resistance to penetration, residual forage biomass, soil cover and yield of corn and soybean from the third to the sixth year of experimentation. The forms of sowing did not affect the chemical properties of the soil, resistance to penetration, the residual forage biomass and the yield of the soybean and corn grown in rotation. The grazing of annual winter forage did not affect the chemical properties of soil and the yield of soybean and corn grown in succession, but residual forage biomass was reduced and resistance to penetration was increased with decreasing deferral intervals. In turn, the fertilisation of winter forages improved the quality of the chemical properties of the soil and increased the residual forage biomass and crop yields in most of the four years examined in this experiment.

“…Higher biomass accumulation was observed in the 2 nd period, which could be attributed to biomass accumulation by plants deposited on the soil surface, and was similar to that observed in other studies with various soil uses in the winter (Lopes et al, 2009;Balbinot Junior et al, 2011).…”

“…In order to rectify the shortage of high quality forage (Aguinaga et al, 2008), hibernal forages like white oat can be grown under an integrated crop-livestock system in areas of direct seeding kept in fallow during the winter period (Balbinot Junior et al, 2011). Such system not only helps to provide vegetal cover (Cassol et al, 2011) but also contributes to the sustainability over time.…”

“…The height management, for example, determines the dry matter produced and the level of residual straw through defoliation (Aguinaga et al, 2008). Black oat and ryegrass, or their associations have been studied for production of forage and straw under different managements (Cassol et al, 2011;Balbinot Junior et al, 2011), but results for white oat (Avena sativa) are still scarce in scientific circles.…”

This study was aimed to evaluate the production of forage and residual straw, structural characteristics and nutritional value of white oat under different soil use in an integrated crop-livestock system. The experiment was conducted in the autumn-winter seasons of 2009, 2010 and 2011 using a randomized block design in a scheme of tracks. Six forms of soil were distributed in tracks and were used to cultivate oats: residue grazing with a height of 10 or 20 cm (G10 and G20); cutting for haymaking with a residue height of 10 or 20 cm (C10 and C20); without grazing or cutting of oat plants with subsequent direct sowing of the summer crop (NC -TS) and without grazing or cutting with subsequent conventional tillage of the soil for sowing of the crop summer (NC -CS). In 2009, 2010 and 2011 three, one and two evaluations were accomplished each year, respectively. We studied the production of forage and residual straw, structural characteristics and nutritional quality of the forage produced. The total forage production in 2009 and 2011 did not differ between soil uses; however, it was higher in the uses with a residue height of 10 cm in 2010. The white oat under cuts or grazing gave high forage dry matter, while straw production was reduced with cuts or grazing. Forage of superior quality and with better production distributed throughout the autumn-winter was obtained when the white oat was managed with grazing or cuttings.

“…Resultados semelhantes foram obtidos por BALBINOT JÚNIOR et al (2011b), que observaram efeito residual do N aplicado na pastagem associado com o efeito da ciclagem de nutrientes sobre a cultura do milho. À medida que aumentam as doses de N aplicada no inverno ocorre aumento da produtividade de grãos na área pastejada, sendo superiores às áreas sem pastejo.…”

RESUMO:O sistema de integração lavoura-pecuária (SILP) é uma alternativa que vem atraindo grande interesse dos agricultores nas regiões produtoras de grão s, devido ao suporte à pecuária por meio da produção de alimento, além de melhoria nas propriedades físicas do solo. O objetivo deste trabalho foi avaliar o efeito do pastejo e da adubação nitrogenada em atributos físicos do solo e na produtividade da cultura do milho, em um sistema de integração lavoura-pecuária. O delineamento foi em blocos ao acaso, com parcelas subdividid as, sendo as parcelas as doses de nitrogênio, e as subparcelas, a presença e ausência de pastejo. Foram utilizadas três repetições por tratamento. Os tratamentos foram doses de nitrogênio de 0; 75; 150 e 225 kg ha -1 aplicados na pastagem de azevém (Lolium multiflorum Lam.) e aveia-branca (Avena sativa Lam.) no inverno. Posteriormente à pastagem, foi implantada a cultura do milho (Zea mays Lam.) no verão. O pastejo com controle da taxa de lotação animal de ovinos e manutenção da massa de forragem consorciada com aveia e azevém não alterou a densidade, a macroporosidade, a microporosidade e a porosidade total no Latossolo Bruno. O pastejo nas áreas que receberam adubação nitrogenada na pastagem, não prejudicou a produtividade da cultura do milho. A adubação nitrogenada da pastagem de inverno, igual ou superior a 150 kg N ha -1 , garante elevada produtividade da cultura do milho na ausência da aplicação de N. PALAVRAS-CHAVE: sistemas integrados, compactação do solo, azevém, aveia, pastagem. EFFECTS OF GRAZING AND NITROGEN FERTILIZATION ON SOIL PHYSICAL PROPERTIES IN A CROP-LIVESTOCK FARMING SYSTEMABSTRACT: Grain farmers have seen integrated crop-livestock systems (ICLS) as an alternative of great interest by providing cattle food supply, as well as improvement of the phisical properties of soil. This study aimed at evaluating the effect of grazing and nitrogen levels on soil physical properties and on corn yield in an integrated crop-livestock farming. The experimental design was a randomized complete block design with a split plot arrangement of treatments and three replications per treatment; nitrogen doses were the main plots, and grazing presence or absence were the subplots. We applied four doses of nitrogen (0, 75, 150, and 225 kg ha -1 ) in soils grown with ryegrass (Lolium multiflorum Lam.) and oat (Avena sativa Lam.) during winter. After the grazing period, the area was planted with corn (Zea mays Lam.) within summer. Sheep grazing with stocking rate control and herbage mass maintenance using oats and ryegrasses did not change soil density, macro, micro and total porosity in a Bruno Latosol (Oxisol). Grazing in nitrogen-fertilized areas did not impair corn yield. Previous nitrogen fertilization in winter grazing, in amounts equal to or higher than 150 kg N ha-1, ensures high corn yields in the absence of N applications.
