“…Consequently, practices that promote SOM input and conservation are essential for the sustainability of these sandy soils. Increases in SOM by composts and other organic residues, with lower or higher values according to the climate and soil conditions of each region, were also reported by other authors (Damatto Júnior et al, 2006;Clemente et al, 2012;Mugnai et al, 2012;Silva et al, 2013).…”

ABSTRACT:Viticulture is an activity of great social and economic importance in the lower-middle region of the São Francisco River valley in northeastern Brazil. In this region, the fertility of soils under vineyards is generally poor. To assess the effects of organic and nitrogen fertilization on chemical properties and nitrate concentrations in an Argissolo Vermelho-Amarelo (Typic Plinthustalf), a field experiment was carried out in Petrolina, Pernambuco, on Syrah grapevines. Treatments consisted of two rates of organic fertilizer (0 and 30 m 3 ha -1) and five N rates (0, 10, 20, 40, and 80 kg ha), in a randomized block design arranged in split plots, with five replications. The organic fertilizer levels represented the main plots and the N levels, the subplots. The source of N was urea and the source of organic fertilizer was goat manure. Irrigation was applied through a drip system and N by fertigation. At the end of the third growing season, soil chemical properties were determined and nitrate concentration in the soil solution (extracted by porous cups) was determined. Organic fertilization increased organic matter, pH, EC, P, K, Ca, Mg, Mn, sum of bases, base saturation, and CEC, but decreased exchangeable Cu concentration in the soil by complexation of Cu in the organic matter. Organic fertilization raised the nitrate concentration in the 0.20-0.40 m soil layer, making it leachable. Nitrate concentration in the soil increased as N rates increased, up to more than 300 mg kg -1 in soil and nearly 800 mg L -1 in the soil solution, becoming prone to leaching losses.

“…No solo, os adubos orgânicos melhoram as características físicas, químicas e biológicas, além de proporcionar, às plantas, maior tolerância ao ataque de pragas e doenças quando aplicados na forma líquida via foliar (Damatto Júnior et al, 2006;2009) e de funcionar como estimulante fito-hormonal, resultando em plantas mais equilibradas (Santos & Akiba, 1996).…”

Com esta pesquisa objetivou-se estudar os efeitos de 5 doses de 4 diferentes tipos de biofertilizante na produção da bananeira Nanicão, em 3 ciclos sucessivos. O experimento foi conduzido em condições de campo, na Escola Agrotécnica do Cajueiro, no município de Catolé do Rocha, estado da Paraíba, Brasil. O solo da área é classificado como Neossolo Flúvico, com textura franco arenosa. O experimento foi conduzido entre os meses de junho de 2008 a junho de 2011. O delineamento experimental adotado foi o de blocos casualizados com 20 tratamentos no esquema fatorial 5x4 (doses x tipos) de biofertilizantes, com quatro repetições. Os resultados mostram que os tipos de biofertilizante não afetaram as variáveis de qualidade da produção; o comprimento e o diâmetro do fruto aumentaram com o incremento da dose de biofertilizante até limites ótimos; o comprimento do fruto das plantas do segundo ciclo foi superior ao das plantas dos primeiro e terceiro ciclos; o diâmetro do fruto das plantas do segundo ciclo foi superior ao das plantas dos primeiro e terceiro ciclos e os valores de ºBrix e de pH da polpa do fruto não foram afetados pelas doses de biofertilizante aplicadas.

“…The treatments fertilized with Humic Substances (HS) and Seaweed (SW) showed average results of Base Saturation, which are considered eutrophic soils (V > 50%). Damatto Junior et al (2006), studying changes in properties of soils fertilized with organic compound obtained similar results, noting the influence of treatments on SB. In their results control treatment showed the lowest index (69%), but this high value of SB was caused by organic matter applied as a compound, which raised the pH due to addition of organic residues and because it adsorbed hydrogen and aluminum in the surface of organic material.…”

Abstract:In this study, we aimed to assess the chemical attributes of a soil fertilized with organic matter, in an agroforestry system. The experiment was carried out at the Miguel Arraes agricultural experiment station of the National Semiarid Institute (INSA), located in Campina Grande, Paraíba, Brazil. Experimental design consisted of a randomized block with four replications. We applied four treatments of organic fertilization: (HS) Humic Substances; (SW) Seaweeds; (B) Bokashi; and (C) control treatment, without fertilization. Soil samples were collected at 0-20 cm depth, placed in plastic bags and taken to laboratory for the following chemical analysis: pH, potassium (K + ), sodium (Na + ), phosphorus (P), calcium (Ca 2+
