“…Prova disso é que vêm sendo observadas correlações diretas entre os teores de Mn do solo e de MO (Castro et al, 1992;Edwards et al, 1992;Motta et al, 2002) e correlações inversas entre o teor de Mn da fração orgânica e a quantidade de Mn absorvida pelas plantas (Sims, 1986 Resultados similares, quanto à eficiência do DTPA-TEA, foram observados por outros autores em solos que receberam aplicação de lodo de esgoto, em condições norte-americanas (Mulchi et al, 1987;Brown et al, 1997), e em alguns estudos desenvolvidos no estado de São Paulo, em solos sem aplicação de lodo (Camargo et al, 1982;Rosolem et al, 1992).…”

“…A tendência de os teores de Mn "trocáveis" da camada superficial serem mais elevados em solos sob SSD, em relação ao SSC (Castro et al, 1992;Edwards et al, 1992;Motta & Prevedello, 1995;Motta et al, 2002), não pode ser explicada apenas pelos valores de pH do solo. No SSD, a aplicação superficial de calcário resulta em valores de pH mais elevados em superfície (Caires et al, 1999;Caires et al, 2000;Moreira et al, 2001), o que, em conseqüência, deveria diminuir e não aumentar os teores desse nutriente.…”

“…Several authors found stabilization of BD after some years under NT (Blevins et al, 1983;Edwards et al, 1992;Díaz-Zorita et al, 2004), while others found the opposite (Moret & Arrúe, 2007).

Section: Last Crop Effects On Soil Hydraulic Properties and On Soil Pmentioning

“…Dick et al (1989) indicated that changes in soil hydrology, created by the imposition of NT practices, are evident only three years after the last tillage operation. For aggregate stability, no changes were reported after five years (West et al, 1991); and for bulk density (BD), no differences were recorded after 10 years (Blevins et al, 1983;Edwards et al, 1992). In contrast, Moret & Arrúe (2007), in a 10-year trial, found increasing values of BD measured three consecutive years, while Díaz-Zorita et al (2004) in a trial of more than 20 years under NT, found differences in soil BD measured two consecutive years.…”

SUMMARYThe area under the no-tillage system (NT) has been increasing over the last few years. Some authors indicate that stabilization of soil physical properties is reached after some years under NT while other authors debate this. The objective of this study was to determine the effect of the last crop in the rotation sequence (1 st year: maize, 2 nd year: soybean, 3 rd year: wheat/soybean) on soil pore configuration and hydraulic properties in two different soils (site 1: loam, site 2: sandy loam) from the Argentinean Pampas region under long-term NT treatments in order to determine if stabilization of soil physical properties is reached apart from a specific time in the crop sequence. In addition, we compared two procedures for evaluating water-conducting macroporosities, and evaluated the efficiency of the pedotransfer function ROSETTA in estimating the parameters of the van Genuchten-Mualem (VGM) model in these soils. Soil pore configuration and hydraulic properties were not stable and changed according to the crop sequence and the last crop grown in both sites. For both sites, saturated hydraulic conductivity, K 0 , water-conducting macroporosity, ε ε ε ε ε ma , and flow-weighted mean pore radius, R 0ma , increased from the 1 st to the 2 nd year of the crop sequence, and this was attributed to the creation of water-conducting macropores by the maize roots. The VGM model adequately described the water retention curve (WRC) for these soils, but not the hydraulic conductivity (K) vs tension (h) curve. The ROSETTA function failed in the estimation of these parameters. In summary, mean values of K 0 ranged from 0.74 to 3.88 cm h -1 . In studies on NT effects on soil physical properties, the crop effect must be considered.Index terms: infiltration, crop rotation, water-conducting porosity, no tillage, texture.( RESUMO: ESTABILIDADE DAS PROPRIEDADES HIDRÁULICAS DO SOLO EM UM SISTEMA DE PLANTIO DIRETO EM LONGO PRAZONos últimos anos, o sistema plantio direto (NT) tem aumentado. Alguns autores indicam que os atributos físicos do solo ficam estáveis após anos cultivando nesse sistema, sendo esse fato discutido por outros autores. O objetivo deste trabalho foi avaliar o efeito do último cultivo após a rotação (1º ano: milho; 2º ano: soja; e 3º ano: trigo/soja) sobre a configuração do sistema poroso do solo e das suas propriedades hidráulicas de diferentes tipos de textura (solo 1: franco; e solo 2: franco-arenoso) da região do pampa argentino, em NT por um longo prazo, para determinar se a estabilidade das propriedades físicas do solo independe do momento da rotação. Adicionalmente, foram comparados os procedimentos para avaliar a macroporosidade, bem como avaliada a eficiência da função de pedotransferência ROSETTA, para estimar os parâmetros do modelo de van Genuchten-Mualen (VGM) desses solos. A configuração do sistema poroso do solo e as propriedades hidráulicas não foram estáveis e se alteraram em razão da rotação da cultura e do último cultivo utilizado na rotação em ambos os solos.

Environmental awareness about soil and water conservation in agroecosystems has shifted behaviors toward favoring conservation practices in agricultural management. Interest in conservation tillage and cover cropping has increased, but some regions encounter major challenges with adjusting management to accommodate these practices while optimizing crop production. In an Ultisol in the North Carolina Piedmont, a long‐term corn (Zea mays) and soybean (Glycine max) rotation with tillage intensities ranging from no‐till to moldboard plowing in a randomized complete block design was used to assess changes in physical soil properties after introducing wheat (Triticum aestivum) as a winter cover crop. Cover crop biomass was measured along with volumetric water content (VWC) and bulk density (BD) at 0–15 cm, water retention (WR), water‐stable aggregation (WSA), and soil organic carbon (SOC) at 0–7.5 cm, and penetration resistance (PR) at 0–45 cm. No differences in VWC or WR could be solely attributed to cover cropping, but no‐till with cover cropping had the highest macroporosity where there was no vehicle traffic. Vehicle traffic had a stronger effect on soil compaction (BD and PR) than cover cropping regardless of tillage. Conservation tillage increased WSA and SOC when compared to plow tillage, but three seasons of a wheat cover crop did not significantly change these properties, possibly because wheat produced low biomass each year (750–1900 kg ha−1). Wheat had minimal effect on physical soil properties in the short term, and potential for improvement with long‐term optimal cover crop management in this region requires further assessment.
