“…Em razão das alterações anteriormente descritas, o tráfego de máquinas promove aumento da resistência mecânica do solo (Jorajuría & Draghi, 1997;Tarawally et al, 2004;Servadio et al, 2005;Botta et al, 2006Botta et al, , 2007, diminuição da capacidade de infiltração de água (Li et al, 2007) e da condutividade hidráulica saturada (Silva et al, 2003;Servadio et al, 2005), alterando a retenção de água no solo (Ajayi et al, 2009). A resistência do solo à penetração é um atributo utilizado na maioria das pesquisas para avaliar a compactação do solo, por esse estar diretamente relacionado ao crescimento das plantas (Letey, 1985), sendo de fácil e rápida determinação (Stolf, 1991), bem como com a umidade, densidade do solo e textura.…”

RESUMOO conhecimento da variabilidade dos atributos físicos do solo é importante para o monitoramento da qualidade do solo, pois eles estão diretamente relacionados com a sustentabilidade da produção agrícola. Este estudo teve como objetivos avaliar e identificar as estruturas de dependência espacial, por meio da construção de semivariogramas, num Latossolo Vermelho-Amarelo (LVA), sob lavoura cafeeira; caracterizar as distribuições espaciais dos atributos físicos pela krigagem ordinária; e identificar a camada com maior impedimento físico. O experimento foi conduzido num LVA textura muito argilosa na Fazenda da Empresa de Pesquisa Agropecuária de Minas Gerais, em Patrocínio, MG. A amostragem foi realizada em trincheiras confeccionadas nas intersecções de uma malha retangular de 40 x 150 m, perfazendo um total de 28 pontos, de onde foram coletadas amostras indeformadas em anéis metálicos de 2,54 cm de altura e 6,30 cm de diâmetro, com auxílio do amostrador tipo Uhland. Cada trincheira possuía três degraus de 2,0 x 1,5 m de superfície, nas camadas de 0,00; 0,10; e 0,25 m, onde se coletaram sete amostras indeformadas em cada degrau, dispostas em forma matricial, totalizando 588 amostras. Os atributos físicos do solo apresentaram estrutura de dependência espacial em todas as camadas, exceto a porosidade total. A técnica de krigagem ordinária demonstrou ser alternativa viável para a estimativa de dados em pontos não amostrados na área experimental. A camada de 0,00-0,03 m apresentou maior impedimento físico ao crescimento de raízes, por apresentar maior densidade e menor macroporosidade do solo.Termos de indexação: compactação, geoestatística, mapas de atributos do solo.

“…Botta et al (2007) based on their 3-year results of soybean in Argentina indicated that direct seeding reduces the number of crossings, which reduces fuel consumption by 35.5% and will be reflected in an increase in the yield of 29.2%.…”

Effect of tillage system and soil conditioner application on soybean (Glycine max (L.) Merrill.) and its crop management economic indicators. Agriculture (Poľnohospodárstvo), vol. 60, 2014, no. 2, pp. 60-69. Ing. Ladislav Kováč, PhD. (*Corresponding author), National Agricultural and Food Centre, Research Institute of Agroecology, 071 01 Michalovce, Špitálska 1273, Slovak Republic. E-mail: kovac@minet.sk Key words: soybean, fertilisation, soil tillage, costs, economic effectiveness 60 Agriculture (Poľnohospodárstvo), 60, 2014 (2): 60−69 DOI: 10.2478DOI: 10. /agri-2014 Experiments with soybean on heavy soils of East Slovak Lowlands were established in the years 2010-2012. The effect of mineral fertilisers and soil conditioner application on soybean's yield using three tillage systems (minimum tillage (MT), conventional tillage (CT) and no tillage (NT)) was studied. Production costs and economic efficiency of crop management practices were evaluated. The influence of production year on soybean crop was significant in the order of 2011, 2010 and 2012. Statistical evaluation confirmed that the effects of CT and MT systems were more significant compared with NT system. No significant differences were found between the variants of the mineral fertiliser and conditioner application. Differences in the total cost of soybean cultivation, as measured between years, were not significant. Fertilisation variants with application of HUMAC agro and NPK generated the highest costs. On the other hand, the lowest costs were achieved at fertilisation variants with application of NPK alone. Comparing tillage variants, the CT system had the highest costs each year. Significant savings were achieved on MT and NT variants. During the experimental period, a profit was reached on all variants. Applying NPK alone, the highest profit was achieved in 2010 and 2012 using MT system and in 2011 with CT tillage. The variant b 2 with PRP sol in the years 2010 and 2011 was the most profitable using NT system and in 2012 using MT. Variant with HUMAC agro was the most profitable in each year using MT. The lowest income threshold for zero profitability was calculated in 2012. Using CT farming techniques at NPK fertilisation variant b 1 in 2012, the income threshold was 1.85 t/ha, at variant b 2 PRP sol it was 2.10 t/ha and at variant b 3 HUMAC agro it was 2.42 t/ha. At MT and NT systems, the income threshold values for zero profitability were lower.Soybean cultivation requires suitable growing conditions. Yield and quality parameters of soybean are affected by many factors, but the appropriate interaction of soil and climatic factors that already exist at the regional level (Anthony et al. 2012), is essential.Soybean, as reported by Šariková and Fecák (2007), is sensitive to incorrect and inconsistent essential tillage. Neglected and poorly made essential tillage makes stand establishment harder and increases the risk of its cultivation. Quality essential tillage is also an arrangement that can substantially eliminate the negative impact of suc...

“…Soil is compacted when the proportion of total volume of pores occupied by air in relation to soil does not permit maximum crop growth. [1] Demonstrated that with the farming methods in the Las Pampas region, due to the traffic of machinery during harvesting, a loss to the producer occurs that ranges between 9% and 38% of the total yield per hectare of soybean crop ( Table 3).…”
