Impacts of biochar and processed poultry manure, applied to a calcareous soil, on the growth of bean and maize

Abstract

Direct use of poultry manure on agricultural lands may cause environmental concerns, so there is a need to establish the suitability of the application of biochar derived from poultry manure for calcareous soil chemical properties and plant growth. The purpose of this study was to evaluate the effects of processed poultry manure (0, 5, 10 and 20 g/kg) and its biochar (0, 2.5, 5, 10 and 20 g/kg) on soil chemical properties of a calcareous soil and growth of bean (Phaseolus vulgaris) and maize (Zea mays) plants. In the incubation experiment, both processed poultry manure (PPM) and biochar decreased pH and the concentration of plant‐available Fe of soil but increased plant‐available P, Zn, Cu and Mn concentrations. PPM and biochar increased the concentrations of exchangeable cations (K, Ca and Mg) in soil. PPM and biochar applications increased the growth of maize and bean plants. PPM and biochar resulted in increased concentrations of N, P, K, Ca, Fe, Zn, Cu and Mn in bean plants. In maize plants, PPM and biochar applications increased the N, P, K, Zn, Cu and Mn but decreased the Ca and Mg concentrations. Results of this study reveal that poultry manure biochar can be used effectively for agricultural purposes.

Effect of thermal conversion of pig manure and poultry litter on the content and mobility of Mn and Fe in biochars and in soil after their application

“…The best results of the deacidifying effect were obtained after application of 1% and 2% amendment of biochars. This effect is due to a higher content of organic matter generates more output of alkali oxides which hydrolyze generate OH groups that increase the pH values (Lehmann et al, 2011;Inal et al, 2015). The results of our research confirm the observations made by Yuan et al (2011), according to which alkaline substances are easier released from biochars than from materials which have not been subjected to thermal conversion.…”

“…Research results obtained by Liu and Zhang (2012) confirm the probability of occurrence of such a situation in a short period of time (4-mo after application). Inal et al (2015) also report that application of PLB led to a reduction of pH in the alkaline soil. According to Liu and Zhang (2012), this may be caused by a release of functional groups of acidic character during oxidation of biochar.…”

Effect of biochar derived from faecal matter on yield and nutrient content of lettuce (Lactuca sativa) in two contrasting soils

“…The ability of biochar to affect the fertility, carbon storage and remediation of soil varies with its characteristics (type of feedstock) as well as the temperature for its creation (Antal and Grønli 2003;Singh et al 2010). As a result, some biochars may be better suited for one or more specific purposes for example of agronomic performance, contaminant stabilization, or carbon sequestration Abbasi and Anwar 2015;Agegnehu et al 2015;Inal et al 2015;Subedi et al 2016). The application of biochar to agricultural land provides several potential benefits including enhancing the cation exchange capacity (CEC) (Glaser et al 2001), water holding capacity (Gaskin et al 2007), and improving organic carbon and nutrient contents of soils (Glaser et al 2002).…”

Redes neurais artificiais na predição da produtividade de milho e definição de sítios de manejo diferenciado por meio de atributos do solo

“…Nos sítios específicos que possuem menor potencial de produtividade, deve-se adotar manejo diferenciado para incrementar principalmente a CTC e MO do solo e, consequente, a produtividade de grãos de milho. Esse manejo é possível com a aplicação de Biochar (Ulyett et al, 2014;Inal et al, 2015) ou resíduos orgânicos da produção de aves (Santos et al, 2014;Inal et al, 2015), ambos aplicados em taxa variável.…”
