“…Greater (13) and lower (8,11) extractable K for no-tillage versus other tillage systems have been reported in surface horizons. Results of a three-year study on a coastal plain soil in Mississippi showed no K accumulation in the 0 to 5-cm depth with no-tillage compared to disking (14) and downward movement of K was also reported with this system.…”

“…Surface lime application in no-tillage often does not ameliorate soil acidity deep within the profile due to limits in lime mobility (10,11). However, results from the only long-term study conducted in the coastal plain region that reported soil chemical properties demonstrated maintenance of soil pH at an acceptable level for crop production after eight years with no-tillage using surface application of lime (9).…”

“…No difference in extractable K between notillage and disk tillage was reported by Karlen et al (9) for an eight-year experiment conducted in South Carolina on a coastal plain soil. On the other hand, P will accumulate more at the surface with no-tillage compared to conventional tillage (8,11). However, considerable P movement, in the organic form, can be obtained by enhancing soil microbial activity (15).…”

Few experiments in the coastal plain region of the southeastern United States have reported the effect of long-term tillage and tillage intensity on chemical soil quality indicators. The purpose of this study was to determine the 17-year influence of four tillage systems on chemical soil quality indicators in a Benndale fine sandy loam (coarse-loamy, siliceous, semiactive, thermic, Typic Paleudults) and a Lucedale very fine sandy loam (fine-loamy, siliceous, subactive, thermic, Rhodic Paleudults) in the coastal plain region of Alabama. Tillage systems were no-tillage, disk, moldboard plow, and chisel plow under varied double-cropping in a randomized complete block design with four replications.

Variação dos valores de pH e dos teores de carbono orgânico, cobre, manganês, zinco e ferro em profundidade em Argissolo Vermelho-Amarelo, sob diferentes sistemas de preparo de solo

RESUMOA semeadura direta vem sendo cada vez mais adotada pelos produtores, e as pesquisas têm gerado maior número de informações sobre os aspectos nutricionais, relacionadas principalmente ao acúmulo de matéria orgânica e nutrientes, notadamente os macronutrientes, como também os aspectos de acidez. Entretanto, existe ainda carência de informações sobre a dinâmica dos micronutrientes neste sistema. Em experimento estabelecido há quinze anos em um Argissolo Vermelho-Amarelo, coletaramse amostras de solo para avaliar a influência de seis sistemas de preparo de solo: semeadura direta (SD), arado de aivecas (AA), arado de disco (AD), grade pesada (GP), grade pesada + arado de aivecas (GP+AA) e grade pesada + arado de disco (GP+AD), sobre os valores de pH e os teores de carbono orgânico, cobre, manganês, zinco e ferro em quatro profundidades (0-2,5; 2,5-5,0; 5,0-10,0 e 10,0-20,0 cm). Foram constatadas diferenças para os valores de pH e os teores de carbono orgânico, cobre, manganês e zinco entre os sistemas de preparo e profundidades amostradas, com os maiores valores sendo observados nos primeiros 5 cm do solo sob o sistema SD. A partir desta profundidade ocorreu similaridade entre os teores em profundidade, com decréscimos mais acentuados na camada de 10 a 20 cm. O teor de ferro mostrou-se influenciado negativamente pela presença de matéria orgânica em superfície nos sistemas SD e GP. Os teores de micronutrientes analisados relacionaram-se positivamente com os teores de carbono orgânico nos diferentes sistemas de preparo e profundidades. Os tratamentos que envolveram maior revolvimento do solo apresentaram maior homogeneidade dos teores de carbono orgânico e micronutrientes ao longo do perfil amostrado.Palavras-chave: semeadura direta, sistemas de preparo e micronutrientes.

“…Moreover, application of modern tillage methods decreases soil agitation, helps in conservation of soil humus, and prevents soil erosion (Hargrave et al 1982). Bonari et al (1995) studied the effect of using multi-task machines, as reduced tillage method, on the yield of crop or soil physical properties.…”

Akbarnia A., Farhani F., 2014. Study of fuel consumption in three tillage methods. Res. Agr. Eng., 60: 142-147.Fuel consumption per hectare of tilled land for the conventional or maximum tillage, reduced tillage using a multi-task machine, and no-tillage using a direct drill planter has been studied and compared. Time taken and number of tractor trips needed for performing tillage operations were used for comparison. Yield of crop per hectare was also used for the study. Duncan's multiple range test was used to compare and analyse the data. Results of fuel consumption were 59.33, 29.67 and 14.33 l/ha for the max. tillage, reduced tillage, and no-tillage cases, respectively. The corresponding yield of crop for these methods were 8.07, 7.90, and 6.33 t/ha, respectively. Therefore, the reduced and no-tillage methods provide enough energy saving per ton of yield to justify their use as good replacements for the max. tillage method in Iran. Also, considering land conditions in Iran, use of direct drill planters is recommended for dry cultivated or traditionally irrigated farms, and multi-task machinery for all types of irrigation systems and land conditions. Keywords: maximum tillage; reduced tillage; no-tillage; multi multi-task machinery; direct drill planter Agriculture, which is the most important sector in the production of food in Iran, is also a big consumer of energy in this country (Farahmandpour et al. 2009). Factors such as time lost for replacement of implements and tools used in conventional (maximal) tillage operations, wear out of tractors, high fuel consumption due to the increased number of tractor trips, and high capital investment needed for purchase of various implements result in higher production costs in the traditional agriculture practice in Iran. In addition, movement of tractors and implements on the soil results in soil compactness, which forms hard pan that prevents the penetration of water and free movement of plant roots deep inside the soil.Mechanization of agricultural operations and use of modern machinery such as multi-task machines and direct drill planters can reduce energy consumption per ton of yield of crop, and results in lower cost of production. Moreover, application of modern tillage methods decreases soil agitation, helps in conservation of soil humus, and prevents soil erosion (Hargrave et al. 1982). Bonari et al. (1995) studied the effect of using multi-task machines, as reduced tillage method, on the yield of crop or soil physical properties. They also focused on the reduction of energy consumption by studying the energy consumption in various tillage methods under different conditions. They reported that reduced tillage resulted in 55% less fuel consumption than the max. tillage, without a significant difference in the yield of crop. Similarly, Craciun et al. (2004) reported that in comparison with the technology with two passes on land, the fuel consumption is reduced by up to 60%. Kosutic et al. (2005) studied the energy consumption in different tillage syst...
