“…The results of this study corroborate those of Briedis et al (2012b), who found a linear relationship between TOC and particulate organic carbon, showing that 21% of TOC was due to the more labile fraction. The results of Briedis et al (2012b) and those found in these studies indicate that the continuous input of residues in brachiria/livestock system increase the carbon of F1 in surface and depth.…”

The crop-livestock integration system significantly increases the carbon content in chemical fractions of soil organic matter (SOM). This study aimed to evaluate chemical indicators of SOM attributes for sites under brachiaria/livestock and pearl millet/no livestock in Goias, Brazil. A third area covered with natural Cerrado vegetation (Cerradão) served as reference. Soil was randomly sampled at 0-5, 5-10, 10-20 and 20-40 cm. Total organic carbon stocks (TOC), oxidizable carbon fractions (OCF) (F1>F2>F3>F4), carbon content in the humin (C-HUM), humic acid (C-HAF) and fulvic acid (C-FAF) fractions were evaluated. F1/F4, F1+F2/F3+F4, C-HAF/C-FAF and (C-HAF+C-FAF)/C-HUM indices were calculated, as well as stocks chemical SOM fractions. Brachiaria/livestock produced greater TOC stocks than pearl millet/no livestock (0-5, 5-10 and 10-20 cm). In terms of OCF, brachiaria/livestock generally exhibited higher levels in F1, F2, F4 and F1/F4 than pearl millet/no livestock. C-HUM (0-10 cm) and C-HAF (0-20 cm) stocks were larger in brachiaria/livestock than pearl millet/no livestock. Compared to the Cerradão, brachiaria/livestock locations displayed higher values for TOC (5-10 and 10-20 cm), C-HAF and C-HAF/C-FAF (5-10 cm) stocks. TOC, C-HAF stock and OCF show that land management with brachiaria/livestock was more efficient in increasing SOM than pearl millet/no livestock. Moreover, when compared with pearl millet/no livestock, brachiaria/livestock provided a more balanced distribution of very labile (F1) and recalcitrant (F4) carbon throughout soil layers, greater SOM humification. Brachiaria/livestock leads to higher values of F1 and F4 in depth when compared to pearl millet/livestock and provides a more homogeneous distribution of C-FAF and C-HAF in depth compared to Cerradão.

“…Although this fact has been well reported in no-till systems (BRIEDIS et al, 2012;FERREIRA et al, 2013;FIGUEIREDO et al, 2007;SÁ;LAL, 2009;), the effect is even more pronounced in the present experiment because the types of organic compounds in OWS are easily oxidized and serve as an energy source for the activity of the microbial community.…”

-The use of organic waste from industrial processes in agriculture is a strategy not only for improving soil properties but also for promoting the utilization of recycled nutrients by market crops and for reducing environmental impact. The aim of this study was to evaluate the effects of using organic waste from pork and poultry slaughterhouses (OWS) applied alone or in combination with mineral fertilizer (MF) on the dynamics of soil organic matter (SOM) compartments. The experimental design adopted was that of completely randomized blocks with six treatments and three replicates. The treatments consisted of a general control (T1) without the addition of MF and OWS, the application of MF alone at 100% of the recommended fertilizer levels for the crops (T2),the application of OWS alone at a fixed dose of 2 Mg ha -1 (T3), and the following three combinations of MF and OWS: 75% MF + 25% OWS (T4); 50% MF + 50% OWS (T5); and 25% MF + 75% OWS (T6). The application of OWS promoted increase in the labile fractions extracted by potassium permanganate (C-OXP) and hot water (C-HW) compared with using MF alone. Using OWS in the combination of 50% MF + 50% OWS increased the content and stock of total organic carbon (TOC) in the 0-20 cm layer and of particulate organic C (POC) and C-OXP in the 0-5 cm layer.Key words: Organic matter compartments. Total organic carbon.RESUMO -A utilização de resíduos orgânicos provenientes de processos industriais na agricultura constitui-se em uma estratégia não apenas para melhoria dos atributos do solo, como também, para proporcionar aproveitamento dos nutrientes reciclados pelas culturas econômicas e redução no impacto ambiental. O objetivo desse trabalho foi avaliar a contribuição do uso de resíduos orgânicos de abatedouros (ROA) de aves e suínos aplicados isolados ou em combinação ao fertilizante mineral (FM) na dinâmica dos compartimentos da matéria orgânica do solo (MOS). O delineamento experimental adotado foi em blocos completamente casualizados com seis tratamentos distribuídos e três repetições. Os tratamentos constituíram-se de um controle geral (T1) sem adição de FM e ROA, e aplicação isolada de FM constituindo o suprimento de 100% da recomendação de adubação para as culturas (T2), aplicação isolada de ROA fixada na dose 2 Mg ha -1 (T3) e três combinações de FM e ROA, sendo: 75% de FM + 25% de ROA (T4); 50% de FM + 50% de ROA (T5); e, 25% de FM + 75% de ROA (T6). A aplicação de ROA promoveu o aumento das frações lábeis (C-OXP e C-AQ) em relação ao uso isolado do FM. O uso do ROA na combinação de 50% de FM + 50% de ROA aumentou o conteúdo e o estoque de carbono orgânico total (COT) na camada de 0-20 cm e do C orgânico particulado (COP) e C lábil extraído com permanganato (C-OXP) na camada de 0-5 cm.Palavras-chave: Carbono orgânico total.

“…soil organic matter (SOM), thus improving edaphic attributes (Briedis et al, 2012;Loss et al, 2014;2015). The use NTSH is a developing management strategy and differs from the current NTS in technological and social aspects, including the non-use of herbicides and the social bias, since this practice has potential for the development of sustainable agriculture (Fayad and Mondardo, 2004;Menezes et al, 2013).…”

Total nitrogen and humic substances in aggregates of soils with onion crops under no-tillage and conventional tillage systems Nitrógeno total y sustancias húmicas en agregados del suelo cultivado con cebolla bajo siembra directa y preparación convencional ABSTRACTThe objective of this study was to evaluate the soil total nitrogen (TN), and N contents in humic substances (HS) of the organic matter in aggregates of soils cultivated with onion under no-till system for horticulture (NTSH) and conventional tillage system (CTS), comparing with an area of forest. The evaluated treatments were natural vegetation (control), 100% black oats, 100% rye, 100% oilseed radish, intercrop of oilseed (14%) + rye (86%), intercrop of oilseed (14%) + black oats (86%), area under CTS of onion for ±37 years, and area with secondary forest for ±30 years. Five years after the NTSH implementation, undisturbed soil samples from the layers 0-5 cm, 5-10 cm, and 10-20 cm were collected; these samples presented aggregate sizes between 2.0 mm and 8.00 mm. The TN, and N contents of the HS were subdivided into fulvic acids (N-FA), humic acids (N-HA), and humin (N-HU) fractions. The change from CTS to NTSH increases the TN and N-HU contents in the 0-5 cm soil layer. The intercrop of oats and oilseed radish, used as soil plant cover species in NTSH, presented a greater increase in N-HU (0-20 cm) than the other treatments. Black oats, and natural Onion (Allium cepa L.) crops cover an area of approximately 60,000 ha annually in Brazil, producing approximately 1.6 million t of onion bulbs (IBGE, 2017). The southern region of the country produces 49% of the national production, where the state of Santa Catarina (SC) stands out as the largest national producer since 1990, with a profitable production that has becoming more sustainable due to organic production studies (ACATE, 2014).Soil conventional tillage system (CTS) is the most used system for onion crops in SC, comprising frequent turning of the soil (plowing, harrowing, subsoiling or scarification) in the preparation of the soil of the planting bed (Menezes et al., 2013). This soil preparation increases the occurrence of erosive processes and changes edaphic attributes, decreasing nutrient availability to plants and soil organic matter content (Loss et al., 2015). CTS is an important system for food, fiber and energy production, however, it impacts the soil; thus, the search for soil management and conservation practices has been a constant challenge. No-till system for horticulture (NTSH) has stood out as a promising alternative for onion crops (Menezes et al., 2013). Soil turning in NTSH is done only in the planting line, and cover plants are used for the production and maintenance of plant residues on the soil. This practice maintains or increases the vegetation presented a greater increased in N-HA, and N-FA contents, respectively, in the 10-20 cm layer, than the other treatments in NTSH and CTS. CTS with millet as soil plant cover presented a greater increase in N-FA (0-20 cm) contents tha...
