“…In one year, Edwards et al (1992) applied a total of 280 kg ha -1 of N to the wheat and corn crops. Motschenbacher et al (2014) applied 337 kg ha -1 of N to only a single corn crop. It is worth noting that Grove and Blevins (1988) did not observe a reduction in the pH value with annual doses of up to 168 kg ha -1 of N applied to corn.…”

“…Although it is recognized that a simple change of the cultivation system from conventional to NT does not increase OM throughout the soil profile, some studies have demonstrated that an increase in OM occurs in the surface layer of the soil, mainly from 0 to 0.05 m (Santiago, Quintero, & Delgado, 2008;Aziz, Mahmood, & Islam, 2013;Motschenbacher, Brye, Anders, & Gbur, 2014;Fink, Inda, Bavaresco, Barrón, & Torrent, 2016;Souza, Figueiredo, & Sousa, 2016). However, there is still a need for long-term studies relating the effect of cropping system to the degree of humification of humic substances (HS) in the surface layer of tropical soils.…”

Soybean macronutrient availability and yield as affected by tillage system

et al. 2019

The effect of tillage system (NT-no tillage; CT-conventional tillage; MT-minimum tillage; and NT/scarification, every three years) on soybean nutrient availability and yield was evaluated on Oxisol after 12 years of cultivation. Soil samples were collected at depths of 0.00-0.05, 0.05-0.10, and 0.10-0.20 m and were analyzed for P, K, Ca, Mg, carbon (C), organic matter (OM), pH value, potential CEC, base saturation (BS%), and number of semiquinone organic radicals. The macronutrient concentration in the leaves and amount accumulated in the plants at the blooming stage were determined, as well as the yield of the two soybean crops. The soil pH value, BS% and K, Ca, and Mg concentrations were not influenced by the tillage system. The soil P and OM in the surface layer, however, were inversely proportional to the intensity of soil preparation. The P content in the soil surface layer under NT was twice as high as that of soil under CT. The P content in the soybean leaves under NT was also higher compared to that in the plants under CT and MT. The number of semiquinone radicals was low in the soil surface layer under NT, indicating a small degree of humification. However, soybean yield was not affected by the tillage system.

“…Cultivation under no tillage (NT) increases the amount of OM in the surface layer (Thomas, Dalal, & Standley, 2007;Santiago, Quintero, & Delgado, 2008;Aziz, Mahmood, & Islam, 2013;Motschenbacher, Brye, Anders, & Gbur, 2014;Vukasinovic, Todorovic, Dordevic, & Rajkovic, 2015;Moreira, Prochnow, Kiehl, Pauletti, & Martin-Neto, 2016) as well as increases the pH when lime is applied to the surface (Caires, Blum, Barth, Garbuio, Kusman, 2003;Teixeira, Souza, Borém, & Silva, 2003;Caires et al, 2005;Fonseca, Caires, & Barth, 2010). In addition, the soil moisture increases and the temperature decreases compared with conventional tillage because organic residues Acta Scientiarum.…”

“…accumulate (Aziz et al, 2013;Motschenbacher et al, 2014). Such features may cause the availability of micronutrients under NT to be different than when the soil is frequently tilled (Moreira et al, 2016).…”

“…In many cases, these high micronutrient levels in the soils were attributed to the application of high rates of N to maize (Zea mays L.) and/or monocultures of grass, which cause a reduction in the pH and, consequently, increases in the availability of certain micronutrients (Grove & Blevins, 1988;Follett & Peterson, 1988;Edwards, Wood, Thurlow, & Ruf , 1992). However, it is known that the increased availability of certain micronutrients, chiefly Mn and Zn, is highly related to the increase of OM in the surface soil (Teixeira et al, 2003;Moreira, Prochnow, Kiehl, Martin-Neto, & Pauletti, 2006;Martin-Rueda et al, 2007;Santiago et al, 2008;Motschenbacher et al, 2014;Moreira et al, 2016). On the other hand, Zn and Mn deficiencies have been noticed especially in corn and soybean crops under NT.…”

<b>Effect of liming on micronutrient availability to soybean grown in soil under different lengths of time under no tillage

et al. 2017

ABSTRACT. The effect of liming on the availability of micronutrients to soybean cultivated during different numbers of years under no tillage (NT) was investigated. The treatments consisted of the number of years under NT (three, six, and nine years) and five rates of lime (0, 33, 67 and 100% of the amount calculated to raise soil base saturation to 70%) broadcast on soil surface plus the rate of 100% broadcast with incorporation in the 0-0.20 m layer of a clayey Red Oxisol. Soil and leaf samples were collected at two vegetative stages of the crop (vegetative V4 and blossoming R2). The soil was sampled at depths of 0-0.05, 0.05-0.10, 0.10-0.20, and 0.20-0.30 m. Surface liming had little effect on extractable soil micronutrient and nutrient concentrations in soybean leaves. In the area with three years under NT, all liming rates decreased the extractable soil Zn up to a depth of 0.20 m. Lime incorporation decreased the extractable soil Mn in the surface layer. There were no differences in the extractable soil micronutrients and nutrient concentrations in soybean leaves as a function of the number of years under NT. These data suggest that broadcasting lime at current rates on soils under NT does not necessarily lead to micronutrient deficiencies.Keywords: copper, iron, manganese, zinc, no till.Efeito da calagem na disponibilidade de micronutrientes para soja, cultivada em solo sob diferentes tempos de cultivo em plantio direto RESUMO. Avaliou-se o efeito da calagem sobre a disponibilidade de micronutrientes à soja cultivada em solo, com diferentes tempos de cultivo sob sistema de semeadura direta (SD). Os tratamentos consistiram de número de anos sob SD (três, seis e nove anos) e cinco doses de calcário (0, 33, 67 e 100% da quantidade necessária para elevar a saturação por bases a 70%), aplicadas em superfície, mais a dose 100% incorporada na camada 0-0,20 m de um Latossolo Vermelho argiloso. Amostras de solo e de folha foram coletadas em dois estádios de vegetação da soja (V4: estádio vegetativo e R2: florescimento pleno). O solo foi amostrado nas profundidades de 0-0,05, 0,05-0,10, 0,10-0,20 e 0,20-0,30 m. A calagem superficial exerceu pouco efeito sobre os teores de micronutrientes no solo e nas folhas de soja. Na área com três anos sob sistema de SD todas as doses de calcário reduziram os teores de Zn até a profundidade de 0,20 m. A incorporação de calcário diminuiu o teor de Mn da camada superficial. Os teores de micronutrientes no solo e as concentrações nas folhas da soja não variaram com os anos de cultivo sob SD. Estes dados sugerem que as doses atualmente empregadas de calcário aplicadas na superfície de solos sob SD não necessariamente conduzem a deficiências de micronutrientes.Palavras-chave: cobre, ferro, manganês, zinco, plantio direto.
