“…Figure 3, the organic matter under NT was composed of significantly higher amounts of humic acids (HA) and humin (HU) and lower amounts of fulvic acids (FA) compared to CT in Vertisol. This is consistent with results obtained by Szajdak et al [65]. The relative decrease in FA under NT compared to CT was probably due to the humification process which was favored by residue management under NT and resulted in a significant increase of the most stable fraction (HA and HU) [66].…”

Stabilizing or improving soil organic carbon content is essential for sustainable crop production under changing climate conditions. Therefore, soil organic carbon research is gaining momentum in the Mediterranean basin. Our objective is to quantify effects of no tillage (NT) and conventional tillage (CT) on soil organic carbon stock (SOCs) in three soil types (Vertisol, Cambisol, and Luvisol) within Central Morocco. Chemical analyses were used to determine how tillage affected various humic substances. Our results showed that, after 5 years, surface horizon (0-30 cm) SOC stocks varied between tillage systems and with soil type. The SOCs was significantly higher in NT compared to CT (10% more in Vertisol and 8% more in Cambisol), but no significant difference was observed in the Luvisol. Average SOCs within the 0-30 cm depth was 29.35 and 27.36 Mg ha −1 under NT and CT, respectively. The highest SOCs (31.89 Mg ha −1 ) was found in Vertisols under NT. A comparison of humic substances showed that humic acids and humin were significantly higher under NT compared to CT, but fulvic acid concentrations were significantly lower. These studies confirm that NT does have beneficial effects on SOCs and quality in these soils.

“…O preparo do solo na olericultura, incluindo a orgânica caracteriza-se por intensivo revolvimento (desestruturação) exigindo mais trabalho (energia) e desequilibrando o ambiente solo-planta, principalmente pela redução da quantidade e qualidade da matéria orgânica e da diversidade dos organismos do solo, fatores que contribuem para diminuição da produtividade das culturas (CIVIDANES, 2002;DAROLT;SKORA NETO, 2008;SZAJDAK et al, 2003).…”

Cultivo orgânico de coentro em plantio direto utilizando cobertura viva e morta adubado com composto 1 Organic faming of coriander in no-tillage system fertilized with compost using dead and living mulching , respectivamente.Palavras-chave -Coentro. Agricultura orgânica. Amendoim forrageiro. Palhada-utilização na agricultura.Abstract -The objective of this work was to evaluate the agronomic behavior of the cilantro in organic no-tillage system under alive and dead mulching and fertilized with doses of compost. The experimental design was randomized blocks, in a split-plot arrangement with four replications. The plot corresponded to the planting system (no-tillage with live mulching of Arachis pintoi, with live mulching of native weed, with mulching of straw and conventional tillage). In each plot the splitplot were represented by the doses of organic compost 10; 20 e 30 t ha -1 of dry compost. The no-tillage system with straw and conventional tillage showed the best results in all variables in the plant compared with no-tillage systems with live mulching of peanut crop and native weed. Cilantro answered linearly to fertilization, with yields of 4,554 t ha -1 to 6,542 t ha -1 when fertilized with 10 to 30 t ha -1 , respectively.

“…O preparo do solo, principalmente na olericultura convencional e orgânica, caracteriza-se por intenso revolvimento, exigindo mais mão-de-obra e desequilibrando o ambiente solo-planta, principalmente pela redução da quantidade e qualidade da matéria orgânica e da fauna do solo (CIVIDANES, 2002;SZAJDAK et al, 2003). Assim, o plantio direto praticado sobre os restos culturais da lavoura anterior, principalmente sobre adubos verdes ou sobre as ervas espontâneas, constitui-se num sistema alternativo ao preparo convencional do solo (SOUZA & REZENDE, 2006 O solo do local foi utilizado com olericultura até o ano de 1984, deixado em pousio com plantas espontâneas, e em 2006 foi implantada a cobertura viva de A. pintoi em parte da área.…”

“…A mesma produtividade no plantio direto na palha necessitaria de apenas 52,8t ha -1 . Isso ocorre porque a incorporação do composto ao solo nos cultivos anteriores aumenta sua decomposição/mineralização, diminuindo seu efeito residual às culturas subsequentes (SZAJDAK et al, 2003).…”
