“…Freiria et al (2008) also found a reduction in the base saturation with increasing depth of the soil profile, and that this reduction was more pronounced when the lime was applied to the surface. Similar results were found in studies conducted by Caires et al (2006) and Caires et al (2008), where it was noticed that the surface liming promoted a large increase in the pH, exchangeable Ca + Mg and base saturation and a reduction in the potential acidity (H + Al), up to 10 cm in depth, in the sampling conducted 12 months after liming.…”

“…Although a number of studies have indicated the success of surface lime application (without soil incorporation) in no-tillage systems, this topic is still under studied for crops that are highly demanding on pH, as is the case with alfalfa. Caires et al (2006), Caires et al (2008) and Rheinheimer et al (2000) found that surface lime application promoted an increases in crop yields, which varied according to species, soil type, fertility conditions and the tillage system implemented. Rechcigl et al (1985) observed that alfalfa showed a production increase in excess of 100% through the application of lime to the soil surface.…”

Furthermore, studies conducted in Brazil have shown increases to pH and to the concentration of exchangeable calcium and magnesium (CAIRES et al, 2006;CAIRES et al, 2008;COSTA and ROSOLEM, 2007), as well as the reduction of exchangeable aluminum in subsoil layers after a surface application of lime (CAIRES; BANZATTO;FONSECA, 2000;PETRERE and ANGHINONI, 2001). …”

-Alfalfa (Medicago sativa L.) requires good soil fertility. Brazil is characterized by acidic soils which reduce the potential of the crop. Generally, liming is incorporated into the soil, but in tillage systems it is inadvisable. This study aimed to evaluate the effects of the lime application method and dose on pH, Al +3 , V % and Ca+Mg in the soil and on dry matter yield of alfalfa cultivated under a consolidated no-tillage system. The experiment was conducted at the Experimental Station of Paraná Agronomic Institute, located in Pato Branco city, in Paraná state. The plots consisted of the types of lime application (plowing+harrowing, subsoil and surface), the sub-plots was the lime dose (0, 2, 4, 6 and 8 Mg ha -1 ) and the sub-sub-plots were the sampled soil depth (0-5; 5-10; 10-20 and 20-30 cm). The results show the application of lime, even superficially, caused increases in pH, concentration of Ca and Mg and base saturation of the soil, while also reducing the concentration of Al, especially in the surface layers of the soil. The practice of plowing and harrowing or of subsoiling, with the aim of lime incorporation in a consolidated no-tillage system is unnecessary. If it is required, the application of lime to the soil should be done superficially for alfalfa cultivated in this system. Key words: Acidity and liming. Liming superficial application.

Por sua vez, o Brasil possui solos ácidos que podem reduzir o potencial produtivo das culturas. Recomenda-se que o calcário seja incorporado ao solo, contudo em sistemas de plantio direto isto é desaconselhado. Este trabalho tem por objetivo avaliar doses e formas de aplicação de calcário para alfafa cultivada em sistema plantio direto consolidado. O experimento foi conduzido na Estação Experimental do Instituto Agronômico do Paraná, localizada no Município de Pato Branco -PR. As parcelas constituíram-se das formas de aplicação de calcário (superficial, subsolador, aração+gradagem), as sub-parcelas pelas doses de calcário (0; 2; 4; 6 e 8 Mg ha -1

SURFACE APPLICATION OF LIMESTONE AND DIFFERENT RESIDUES ON SOYBEAN GROWN IN NO-TILL SYSTEMThe practice of correcting soil acidity by surface application of pH-correcting materials on crop residues in the no-till system is restricted to limestone. No further studies are available on the use of steel slag, lime mud, and centrifuged sewage sludge. The objective of this study was to evaluate soil acidity and yield of soybean as a function of surface application of centrifuged sewage sludge, lime mud, steel slag, and dolomitic limestone. The study was conducted on a dystrophic Clayey Rhodic Hapludox soil, during the 2002-2005 cropping seasons, under no-till system. Treatments consisted on surface application of slag -E, lime mud -Lcal, centrifuged sewage sludge -LC, dolomitic limestone, and zero application of correcting materials, conducted in a random block design with four replicates. Surface application of steel slag, lime mud, and centrifuged sewage sludge allowed soil acidity correction, Ca 2+ displacement, increased base saturation, and Al 3+ reduction down to 40cm depth, whereas for limestone those effects occurred down to 20 cm. The interaction among those factors promoted a soybean yield increase for the LC, E, Lcal, and limestone treatments in the 2003/04 and 2004/05 seasons, as well as for the LC and E treatments in the 2002/03 season, under the no-till system.

Exploring the synergism between surface liming and nitrogen fertilization in no‐till system

Surface liming to correct soil acidity may have limited effectiveness in subsurface layers in no-till systems (NTS). The possibility of downward movement may be increased when liming is combined with fertilization with urea (ammoniacal N), as NO 3 formed by nitrification of NH 4 + can form ion pairs with exchangeable Ca 2+and Mg 2+ . Liming can also increase the nitrogen use efficiency (NUE) of crops and reduce dependence on soil N. In this work, we investigated the effects of surface application of lime under NTS and N topdressing on soil chemical properties and the nutrition, productivity, and NUE of maize (Zea mays L.) and upland rice (Oryza sativa L.). The treatments comprised four lime rates applied superficially (0, 1,500, 3,000, and 6,000 kg ha -1 ), and absence (-N) or presence of N fertilization (+N) as urea by topdressing. The treatments were applied during two agricultural years (2011/2012 and 2012/2013), with maize in the first crop season and upland rice in the second crop season. At 18 mo after liming, the application of 6,000 kg lime ha -1 significantly improved the chemical attributes of the soil (pH, soil organic matter (SOM), K, Ca 2+ , Mg 2+ , and base saturation [BS]). The application of urea increased the mobility of Ca 2+ and Mg 2+ to greater depths. The combination of 3,000 kg lime ha -1 with N fertilization synergistically increased the nutrition (N, P, and S), grain yield, and N-related efficiency indexes in the maize and upland rice crops.
