“…O cultivo de plantas, como B. ruziziensis, com elevada capacidade de absorver K pode influir na relação entre as reservas de K do solo e na sua disponibilidade, acarretando alterações dos minerais potássicos do solo (Velde & Peck, 2002;Simonsson et al, 2009). Hinsinger & Jaillard (1993) verificaram a formação de vermiculita, em detrimento de ilita, no solo da região da rizosfera das raízes de azevém (Lolium multiflorum) em apenas 32 dias de cultivo.…”

“…Fraga et al (2009) verificaram que a contribuição do K não trocável para a nutrição de plantas de arroz variou de 12 a 72 %, com e sem adição de K no primeiro cultivo, respectivamente. A contribuição de formas de K inicialmente consideradas não trocáveis às plantas comumente é reportada na literatura, mesmo quando há adição de fertilizante potássico (Rosolem et al, 1988;Calonego et al, 2005;Kaminski et al, 2007;Simonsson et al, 2009). Rosolem et al (1993) constataram que a forma não trocável, independentemente do solo, foi a principal fonte de K para a soja.…”

Rosolem et al (1993) constataram que a disponibilização do K não trocável em cinco solos tropicais, independentemente do tipo de solo, manteve equilibrados os níveis de K trocável do solo durante o desenvolvimento das plantas.…”

“…In an experiment carried out in the State of Rio Grande do Sul, Brazil, Simonete et al (2002) estimated that, even considering the residual effect of ryegrass potassium fertilization on succession-grown rice, at least 30% of the total K taken up by plants was in non-exchangeable form. The exploitation of K forms initially considered non-exchangeable for plants has been commonly reported in the literature, even in scenarios involving potassium fertilizer application (SIMONSSON; HILLIER; ÖBORN, 2009;GARCIA et al, 2008). Rosolem, Bessa and Pereira (1993) found that regardless of soil type, non-exchangeable forms of K were the main sources of the nutrient for soybean crops.…”

The use of crop rotation and manure application can provide sustainability for an agricultural production system by improving soil quality and increasing nutrient use efficiency. This study aimed to evaluate the effect of mineral, organic and mineral+organic fertilization on grain yield and on soil phosphorus and potassium balance, in two crop systems under no-till, with and without rotation of cover crops. The experiment was carried out from 2006 to 2008 on a clayey Rhodic Hapludox in Marechal Cândido Rondon, Paraná State, Brazil. The cropping sequence in the rotation system involving cover crops was black oat + hairy vetch + forage turnip/corn/pigeon pea/wheat/mucuna + brachiaria + sunn hemp, and in the succession system was wheat/corn/wheat/soybean. Organic and mineral+organic fertilizations consisted of the application of solely manure and manure combined with mineral fertilizer, respectively. Soil P and K balances were calculated after the second year of the experiment, up to a depth of 0.40 m. First year corn yields were higher in the crop succession system accompanied by mineral fertilization. In the second year, wheat and soybean yield did not vary between crop systems and nutrient sources, demonstrating the residual effect of crop rotation and manure use. Crop rotation with cover crops resulted in an increase in soil K levels by promoting the recycling of this nutrient in the soil. In both crop systems, the application of mineral and organic fertilizers -either in isolation or in combinationresulted in a negative soil P and K balance in the short term. This represents a threat to the sustainability of the agricultural production system in the long term, due to the depletion of soil nutrient reserves.

O objetivo deste trabalho foi avaliar o efeito da adubação mineral, orgânica e mineral+orgânica na produtividade de grãos e no balanço de fósforo e de potássio no solo em dois sistemas de culturas sob plantio direto, com e sem rotação de plantas de cobertura. O experimento foi conduzido em Marechal Cândido Rondon, Paraná, Brasil, de 2006 a 2008, em um Latossolo Vermelho. A sequência de culturas no sistema em rotação com plantas de cobertura foi aveia preta + ervilhaca + nabo/milho/guandu/trigo/ mucuna + braquiária + crotalária / milho, e no sistema em sucessão foi trigo/milho/trigo/soja/milho. As adubações, orgânica e mineral+orgânica consistiram, respectivamente, da aplicação de esterco e de esterco combinado com fertilizante mineral. O balanço de P e de K no solo foi avaliado, após o segundo ano de condução do experimento, na camada de 0,0-0,40 m de profundidade. A produtividade do milho, no primeiro ano, foi superior na sucessão de culturas e na adubação mineral. No segundo ano, a produtividade de trigo e de ...

“…(Ross 1971;Chaudhuri et al 2007). At the decennial time-scale, subtle changes in clay mineralogy caused by depletion and replenishment of K through management practices have been observed and characterised in several studies (Velde and Peck 2002;Barré et al 2007aBarré et al , b, 2008Simonsson et al 2009). Studies with high resolution in time and space have shown that root-soil interactions may alter the K content of clay minerals in forest soils in the lapse of only a few months to an extent that may be measured with conventional mineralogical and geochemical methods (Turpault et al 2007(Turpault et al , 2008Calvaruso et al 2009).…”

Clay minerals and K feldspars were evaluated as sources of K in a Norway spruce stand (Picea abies (L.) Karst.) from the Skogaby experimental forest in southwest Sweden. The soil, developed in a Quaternary glacial till, has only 3-5% clay, and more than 95% of its K resides in feldspars. Ratios of K/Rb were assessed in interlayers of 2:1 clay minerals (extracted with hot (100°C) 2 M HCl), biomass and the forest floor. These compartments had similarly low K/Rb ratios, whereas K feldspars were significantly poorer in Rb. A fractionation model indicated preferential retention of Rb in the biomass and forest floor, due to stronger adsorption of Rb than K in the humus, as well as preferential uptake of K from the exchange complex in the mineral soil. Preferential uptake of K may result from weaker adsorption of K by the cation exchanger, or preference for dissolved K over Rb by the roots. A quantitative mineralogical analysis revealed that loss from micas may account for half of the Holocene loss of K from the soil, which was approximately 22 Mg ha -1 . Exceptionally low K/Rb ratios in HCl extracts of the upper 60 cm of the profile indicated extensive loss of K from mica in the parent material and re-fixation of K and Rb at lower ratios. The results indicate that fixation in and release from clay minerals may be prominent in the cycling of K, even in a soil that is poor in clay minerals.
