“…TN contents can be reduced with the conversion of native Cerrado areas to agricultural activities, as reported by Souza et al (2016) in murundu fields in the Cerrado of Goiás. This was also observed by Silva et al (2016), who found reduction in TN contents after the conversion of native Cerrado area to various agricultural activities. However, in this study it can be observed that the use of turkey litter can increase TN contents, being an important tool to mitigate possible negative effects of some agricultural activities on the contents of this element in the soil.…”

“…The conversion of Cerrado areas to areas of agricultural activities can lead to reduction of TOC contents in the initial years of its implementation. On the other hand, POC contents can be recovered with integrated production systems after 3 years of adoption (SILVA et al, 2016). These authors also point out that the recovery of POC contents is mainly related to the role played by the roots of Urochloa ruziziensis, used after the soybean cycle.…”

“…The conversion of the native Cerrado areas to agricultural activities can initially reduce the C stored in the soil (SILVA et al, 2016). However, conservation systems can minimize the impacts of agricultural activities and recover the amount of C lost in the initial soil tillage operations (SOUZA et al, 2016).…”

Residues from turkey production are often used as fertilizers in pastures near producing regions. These residues can contribute to the increase of carbon and nitrogen stocks in the soil. This study aimed to evaluate the cumulative effects of nine applications of turkey litter rates on C and N fractions and stocks in a Latossolo Vermelho distroférrico (Oxisol) cultivated under rotational grazing. The experimental area was divided into 16 pickets of 0.5 ha each and cultivated with Urochloa decumbens in a rotational grazing system. The treatments consisted of accumulated doses of turkey litter (38.3; 54.8 and 69.2 Mg ha−1), with applications carried out between 2008 and 2017, in addition to a control treatment, without application of this material. After nine years of application, total organic carbon (TOC) and total nitrogen (TN) stocks in the soil increased as turkey litter rates increased, reaching increments in the 0-0.2 m layer of 11.2 Mg ha−1 and 1.03 Mg ha−1, respectively, when compared to the control treatment. In the same 0-0.2 m layer, the maximum increments in carbon stock in particulate organic matter (POC) and nitrogen stock in particulate organic matter (N-POM) were obtained with the estimated total doses of 62 and 66 Mg ha−1, respectively. In addition to increasing the amount, the use of turkey litter improved the quality of the carbon present in the soil, since the carbon management index, in the 0-0.2 m layer, was increased by 124% when using the highest accumulated dose.

“…This is why, in some cases, increases in the OM content of soils under Cerrado cultivated under NT occur only after long periods. Silva et al (2016) did not observe a recovery of the OM content back to the original value existing in the native Cerrado areas after 10 years of cultivation.…”

“…It is believed that the increase in the OM content at the surface is faster if rotations with a predominance of grasses that produce high amounts of residues are used . This fact is more relevant, especially for soils under Cerrado, where the decomposition process is faster due to higher moisture and temperature conditions (Silva, Bonetti, Souza, Paulino, & Carneiro, 2016). This is why, in some cases, increases in the OM content of soils under Cerrado cultivated under NT occur only after long periods.…”

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.
