“…The NMS analysis showed different responses related to CTS amendment over the six years and suggested that there was an improvement in the chemical properties of the soil at the highest rate of CTS application. Previous studies with organic compost also found a strong improvement in soil fertility (Scherer, Metker, & Welp, 2011;Patel & Patra, 2014). In addition, the soil structure was better with the amendment of CTS at a high application rate, which indicates that high levels of CTS may improve the physical properties of soil in the long-term.…”

ABSTRACT. This study evaluated soil properties and cowpea yield after six years of consecutive amendment of composted tannery sludge. The compost was applied annually at 0, 2.5, 5, 10, and 20 Mg ha -1 and at the end of the sixth year, the chemical and physical properties of the soil were evaluated using a randomized block design. The Cr, P, K, Ca, Na and organic C contents and the pH and cation exchange capacity increased linearly after six years of compost amendment. The soil bulk density decreased linearly while the aggregate stability index increased after compost amendment. As a consequence of the changes in the chemical and physical properties of the soil, cowpea yield showed a quadratic response to the tannery rates, with an estimated maximum cowpea yield at 8.3 Mg ha -1 . In conclusion, the soil chemical and physical properties improved after six years of composted tannery sludge amendment. However, the soil pH and the Cr and Na contents increased with composted tannery sludge amendment, which influenced the cowpea yield and resulted in a quadratic response to the compost.Keywords: waste management, soil fertility, soil quality.Propriedades do solo e produtividade do feijão-caupi após seis anos de aplicações consecutivas de lodo de curtume compostado RESUMO. Este estudo avaliou as propriedades do solo e a produtividade do feijão-caupi após seis anos de aplicações consecutivas de lodo de curtume compostado. Anualmente, o composto foi aplicado a 0, 2,5, 5, 10 e 20 Mg ha -1 e no sexto ano as propriedades químicas e físicas do solo e a produtividade do feijão-caupi foram avaliadas em experimento de blocos casualizados. Cr, P, K, C orgânico, pH, Ca, Na, e a capacidade de troca de cátions aumentaram linearmente após seis anos de aplicação do composto. A densidade do solo diminuiu linearmente enquanto a estabilidade de agregados aumentou após a aplicação do composto. Em consequência das mudanças nas propriedades químicas e físicas do solo, a produtividade do feijão-caupi apresentou resposta quadrática às doses de lodo de curtume compostado com máxima produtividade estimada encontrada na dose de 8,3 Mg ha -1 . Em conclusão, as propriedades químicas e físicas do solo melhoraram após seis anos de aplicação do lodo de curtume compostado. Entretanto, o pH do solo, bem como os teores de Cr e Na aumentaram com aplicação do lodo de curtume compostado e estes parâmetros influenciaram a produtividade do feijão-caupi que apresentou resposta quadrática.Palavras-chave: manejo de resíduos, fertilidade do solo, qualidade do solo.

“…The long-term application of FYM, as a rule, increased the C org content of the soil (Dunjana et al, 2012;Fageria, 2012;Šimon, Czakό, 2014;Blanchet et al, 2016). However, as showed by Scherer et al (2011), after 45 years of repeated applications of FYM (every second year 4.5 and 9.0 t ha -1 on a dry weight basis) the C org content did not significantly differ from the control.…”

The benefit from organically cultivated crops is strongly related to the maintenance of soil fertility based to a great extent on the soil organic matter content. Farmyard manure (FYM) is one of the more valuable organic fertilizers maintaining soil fertility in the systems of alternative agriculture. To investigate the influence of FYM from several aspects, a field experiment was carried out on a sandy loam Albic Stagnic Luvisol (LVab-st). A five-year crop rotation (potato → oats → barley → clover → rye) was organically managed without manure (ORG) and with manure (ORGFYM) treatments. 8.3 t ha -1 of organic dry matter as solid cattle farmyard manure was spread prior to the rye stubble ploughing for potato grown the next year. For the both treatments, the whole mass of clover and straw was ploughed into the soil. During a seven-year experimental period, no significant changes were found in the soil organic carbon (C org ) content. For the ORG treatment, a significant (P < 0.05) decrease in potassium, copper and boron contents in the soil occurred. The application of FYM significantly increased the contents of phosphorus and magnesium in the soil. Under the influence of FYM, the yields of potato, oats and barley increased by 52, 23 and 10 %, respectively; this allowed us to gain an extra 30 GJ metabolizable energy during the crop rotation. The economic calculations showed that the application of farm own manure was profitable even if the yield was sold as a non-organic product. If the yield is sold as an organic product, it would be profitable if the transportation distance of purchased manure to the fields is up to 15 km.

“…In addition, soil collected from the cultivation of maize in reduce tillage was characterized by a high biological activity. Soil microorganisms play a fundamental role in promoting growth and development of plants (Scherer et al 2011, Zhang et al 2012. The yield of maize (grain, straw) correlated with some biological activity of soil (Table 6).…”

Soil microbial functional diversity under maize grown in different agricultural management practices was determined using the Biolog EcoPlates and other microbial and biochemical methods. Comparisons of substrate utilization and the diversity indices showed differences in community composition of microorganisms related to different cultivation techniques and seasons. The soil samples collected in spring were characterized by statistically significant lower indices of biological activity in comparison to the soil collected from the flowering stage of maize. The soils collected in spring from the plots with full tillage had a similarly high biological activity as the soils obtained from maize flowering season. The principal component of PC analysis, showed the strong correlation between the parameters of soil quality and biodiversity indicators. Selected indicators of soil microbial diversity explained 71.51% of biological variability in soils. Based on the PC analysis, two major groups of soils have been indicated. Management practices and seasons were two important factors affecting soil microbial communities.
