ABSTRACT: The objective of this work was to evaluate the efficiency and the residual effects of both molten and ground alkaline potassium-silicate rocks (K1) and of ground phonolite rock (K2), as sources of potassium, compared with the traditional source (KCl), in grain crop successions. Two experiments ? one with the succession soybean-wheat-corn and the other with the succession corn-millet-soybean ? were conducted on a Typic Haplorthox in a randomized complete block design with four replicates. The treatments consisted of three sources (KCl, K1, and K2) and four rates of K (corresponding to 0, 0.5, 1.0, and 2.0 times the recommended rates for soybean and corn). The used sources did not affect leaf K concentration in soybean, but KCl and K2 similarly increased leaf K concentration in corn. Regardless of the source, K application increased the yield of all crops. The K1 and K2 sources present agronomic efficiencies equivalent to that of KCl. K1 and K2 show a more pronounced residual effect than KCl, especially on crops grown approximately one year after their application and under K rates above those recommended for the crops. Index terms: agronomic efficiency, phonolite, potassium fertilization, residual effect, rock dust, silicon. Eficiência e efeito residual de fontes alternativas de potássio em culturas graníferas RESUMO: O objetivo deste trabalho foi avaliar a eficiência e o efeito residual de rochas potássico-silicáticas alcalinas fundidas e moídas (K1) e de rocha de fonolito moída (K2), como fontes alternativas de potássio, em comparação à fonte tradicional (KCl), em sucessões de culturas graníferas. Dois experimentos ? um com sucessão soja-trigo-milho e outro com sucessão milho-milheto-soja ? foram conduzidos em Latossolo Vermelho argiloso, em delineamento de blocos ao acaso, com quatro repetições. Os tratamentos consistiram de três fontes (KCl, K1 e K2) e quatro doses de K (correspondentes a 0, 0,5, 1,0 e 2,0 vezes a dose recomendada para a cultura da soja e do milho). As fontes não afetaram a concentração de K nas folhas da soja, mas KCl e K2 aumentaram de forma semelhante a concentração de K nas folhas do milho. Independentemente da fonte, a aplicação de K aumentou as produtividades de todas as culturas. As fontes alternativas K1 e K2 apresentam eficiências agronômicas equivalentes à do KCl. K1 e K2 têm efeitos residuais mais pronunciados que o do KCl, especialmente em cultivos realizados aproximadamente um ano após suas aplicações e com doses de K acima das recomendadas para as culturas.

One likely consequence of global warming, which is mainly due to the anthropogenic influence (IPCC, 2007), would be the changes in the accumulated chilling hours in temperate fruit crops. Global warming might have dramatic effects in the most warmer fruit zones, e.g., the Southern Region of Brazil. Simulations were performed to assess the effect of increasing minimum air temperature by 1°C, 3°C and 5.8°C in the chilling hours, on temperate fruit crops. Data from 81 meteorological stations of Paraná (Iapar), Santa Catarina (Epagri) and Rio Grande do Sul (Fepagro) States were used to develop a model to estimate the chilling hours (Ch) as a function of the average minimum air temperature from May to September (Tmin may-sep) and the annual average of the minimum air temperature (Tmin annual). The generated model was used into the geographical information system (GIS) to create, through regression equations, information plans of the actual average minimum temperature (May to September) and actual annual average minimum temperatures. To the information plans generated by the equations were added the temperatures of 1°C, 3°C and 5.8°C. These data were used to generate, with GIS, maps of actual and future chilling hours. If the scenario of increasing 1°C is confirmed, it will decrease the areas with higher accumulated chilling hours (ACH) and increase the areas with lower ACH. This pattern will be more pronounced with an increase of 3°C, and culminate with an increase of 5.8°C where practically all areas with ACH would disappear, with the exception of small areas on the highest places of Rio Grande do Sul and Santa Catarina States, where the maximum ACH would be 334 hours.
