“…The production of DM by the soil coverages studied are above the averages observed in other studies also conducted in the Brazilian Cerrado biome, ranging from 7 to 12 Mg ha -1 for C. juncea (Torres et al, 2017), 3.8 to 7.2 Mg ha -1 for C. ensiformis (Padovan et al, 2011;Torres et al, 2014) and from 2 to 7.2 Mg ha -1 for the fallow area (Crusciol & Soratto, 2009). The great biomass production observed in this study is probably due to the adequate water availability and temperature that occurred in the region during the study period.…”

Conservationist systems of crop management increases the amount of substrate, alters fertility and increases soil biological activity. The objective of this study was to evaluate the influence of soil management systems on the chemical attributes and microbial activity of soil under cassava crop. The experiment was set as completely randomized design in a factorial scheme of 2 x 3 x 2, being two systems of cultivation (minimum with only mown; minimum with mown and incorporation), three types of soil coverage (fallow; Crotalaria juncea L.; Canavalia ensiformis L.) and two soil depths (0-0.10 and 0.10-0.20 m), with four repetitions. The production of dry mass from cover crops, the soil chemical attributes and the soil microbial activity were evaluated. There were no differences between management systems, and the C. juncea cover crop presented superior dry mass production among the soil coverages. The concentrations of soil Ca and K were greater in the fallow coverage and C. juncea areas in the 0-0.10 m soil layer; however, these nutrients differ in the soil layer below (0.10-0.20 m). There were no differences for the basal respiration of soil microorganisms in both soil depths or among soil coverage, but the carbon from microbial biomass was superior in the most superficial soil layer where more substrate is available to soil microorganisms.Atributos químicos e atividade microbiana do solo cultivado com mandioca sob diferentes coberturas vegetais RESUMO: O aporte de resíduos vegetais no solo proporcionado pelos sistemas conservacionistas de manejo aumenta a quantidade de substrato, altera a fertilidade e aumenta a atividade biológica do solo. O objetivo deste estudo foi avaliar a influencia dos sistemas de manejo nos atributos químicos e na atividade microbiana do solo sob cultivo de mandioca. Com delineamento inteiramente casualizado, em esquema fatorial 2 x 3 x 2, foram avaliados dois sistemas de cultivo mínimo (somente roçado; roçado e incorporado), três tipos de cobertura (pousio; Crotalaria juncea L.; Canavalia ensiformis L.) e duas profundidades (0-0,10 e 0,10-0,20 m), com quatro repetições. Foram avaliados a produção de massa seca das coberturas, os atributos químicos e a atividade microbiana do solo. Não houve diferenças entre sistemas de cultivo mínimo e a C. juncea apresentou a maior produção de massa seca. Os teores de potássio e cálcio foram superiores nas áreas com resíduos de pousio e C. juncea na camada de 0-0,10 m; no entanto, estes nutrientes diferem na camada do solo abaixo 0,10-0,20 m. Não houve diferenças entre a respiração basal de microorganismo do solo em ambas as profundidades e coberturas, mas o carbono da biomassa microbiana foi superior na camada mais superficial, onde há mais substrato disponível para os microorganismos do solo.

“…In their studies, Assis et al (2016) and Torres et al (2017) observed similar results when using brachiaria, since the rate of decomposition of the brachiaria residues were accelerated when compared to crotalaria and millet, suggesting that it is not only the C/N ratio of plant residues to decisively affect the process of plant residue decomposition. The C/N that these plants feature in monoculture, when compared with cover crop mixtures, may present middle or higher ratios of decomposition, as evidenced in other studies carried out in the same region (Torres et al, 2013;Assis et al, 2016;Pacheco et al, 2013).…”

“…Some other studies evaluating the decomposition of residues of millet, sunn hemp and brachiaria in natural conditions (no artificial irrigation) showed that the greatest rates of decomposition always occur on Fabaceae, and minor in Poaceae (Carvalho et al, 2011;Assis et al 2016;Torres et al, 2015Torres et al, , 2017. These authors also observed that the rates are directly influenced by soil moisture because the decomposition increases in parallel to the increase of water availability that occurs in the rainy period and decrease to minimum values in the dry period (Torres et al, 2008;Pacheco et al, 2017).…”

The decomposition of plant residues, the changes in the total organic carbon (TOC) and the fractions of soil organic matter (SOM) occur differently in irrigated areas. The objective of this study was to quantify the biomass production, the decomposition of cover crops residues and relate them with the changes n the content and fractions of SOM in an irrigated area of vegetable crops. Six types of cover crop treatments were evaluated: brachiaria (B); sunn hemp (S); millet (M); B + S; B + M; S + M, plus an additional treatment (native area), with 4 repetitions. The production of fresh (FB) and dry biomass (DB), the rate of plant residue decomposition, TOC, SOM fractions and the coefficient of SOM (QSOM) were quantified. It was observed that the greatest and the lowest volume of crop residues were from the B and S cover crop, respectively. The cover crops in monoculture presented great decomposition rates and short half-life when compared to mixtures of cover crop. The TOC and QSOM were great in the 0 to 0.05 m soil layer, and in the M + S cover crop mixture, when compared to the 0.05 to 0.1 m soil layer and to other cover crops. Among the SOM fractions, the humin predominated in the most superficial soil layer (0 to 0.05 m).

“…Similarly, Rosen et al [15] found that the application of 250 kg ha −1 N increased the cabbage yield by 17% compared to a low nitrogen rate of 125 kg ha −1 N. In another study, Cui et al [7] reported that the application of the inorganic fertilizer N-P-K (15-6.5-12.4) increased the cabbage yield by 18.3% compared to a control treatment in which no N was applied, and the combined application of inorganic fertilizer with organic fertilizer further increased the crop yield. In an experiment conducted in Brazil, the application of 150 kg ha −1 N, 100 kg ha −1 P 2 O 5 and 100 kg ha −1 K 2 O increased the cabbage yield by 45.6% compared to the control treatment [16].…”

Cabbage is an annual vegetable crop species cultivated throughout the year. The development of high-yielding cabbage hybrids and the optimization of several agronomic management practices such as fertilization and crop rotation have resulted in increased soil fertility, crop yield and product quality. This study aimed to investigate the effects of the farming system (organic and conventional) and the applied rotation scheme on soil nutrient content, head yield and the nutrient content of cabbage. The preceding crops included either pea (P), faba bean (F) or cabbage (C), and thus, the rotation schemes were P-C, F-C and C-C. Sheep manure was applied in the organic farming system, and the inorganic fertilizer 11-15-15 (N-P2O5-K2O) was applied to the conventionally cultivated plants. The results reveal an interaction between the farming system and the preceding crop for the head yield, with the lowest values (57.00 t ha−1 and 53.87 t ha−1 in 2015/2016 and 2016/2017, respectively) recorded in plots where cabbage was cultivated as a preceding crop under the organic farming system. The N, P and K contents in head tissues were affected only by the farming system, with the greatest values recorded in the conventional farming system. Both factors affected the nutrient content in the soil. Specifically, the highest values of NO3− and total N content in the soil were recorded in the P-C and F-C rotations, and the K content was higher in the continuous cabbage cropping system (C-C). Moreover, the NO3−, P and K contents in the soils were higher in the conventional farming system compared to the organic system. To conclude, combining inorganic fertilization in a crop rotation scheme with legume species such as pea and faba bean as preceding crops for cabbage can result in increased soil fertility and head yield.
