Poultry manure (PM) chars were obtained at different temperatures and charring times.
Chemical–physical characterization of the different PM chars was conducted by cross …

The effect of pyrolysis temperature on the nutritional quality of agricultural biochar is unclear,
so better understanding of its properties and how it affects soil nutrient availability and plant …

This study was conducted to investigate the effect of pyrolysis temperature on chemical
properties of poultry manure (PM) biochar over the range of 200–500° C. Chemical …

The analysis was performed to research the speciation and bioavailability of heavy metals in
manures and the biochars obtained from pyrolysis of swine and goat manures. Manures …

Biochar research has focused in the last years in the use of wood or grass derived materials
for carbon sequestration. However, manure derived biochar can provide other benefits after …

While pyrolysis of livestock manures generates nutrient-rich biochars with potential
agronomic uses, studies are needed to clarify biochar properties across manure varieties …

Highlights•High temperature increased aromaticity and stability of biochar.•High temperature
reduced the leaching toxicity of heavy metals.•The O/C ratio was capable of evaluating the …

Despite the recent interest in biochars as soil amendments for improving soil quality and
increasing soil carbon sequestration, there is inadequate knowledge on the soil amendment …

Three biochars were prepared by intermediate pyrolysis from poultry litter at different
temperatures (400, 500, and 600° C with decreasing residence times) and compared with …

Biochars were slowly pyrolyzed from dried swine manure waste by slow pyrolysis at different
temperatures (300–750° C) and heating times (0–120 min). The influence of pyrolysis …
