“…Paz-Ferreiro et al (2014) concluded that biochar as amendment can improve plants growth with some additional effects such as (i) improve biological activity of soil and at the same time that decrease the toxicity of the soil, (ii) biochar acts like a slow release fertilizer and increases microbial biomass, (iii) regulate soil pH. Furthermore, other benefits, including carbon sequestration, binding of nutrients and improved soil water retention capacity (Liang et al, 2014;Mendez et al, 2012;Paz-Ferreiro et al, 2012) have also been reported frequently in the literature.…”

“…On the other hand, the soil application of biochars obtained from pyrolysis of ash-rich wastes such as sewage sludges have positive effects on soil agricultural properties as an increment of water holding capacity, improvements on organic carbon content and liming effect [6] or positive effects on soil biochemical properties [13]. Indeed, Liang et al [14] observed an increment of the resistance of both the bacterial and fungal networks to drought on an Acrisol amended with poultry litter biochar while Lu et al [15] reported that biochar addition improves soil biochemical properties in a soil polluted with Cd.…”

a b s t r a c tBiochar 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 soil addition, including nutrient supply. At present, there is an incomplete understanding of pyrolysis on manures. In order to understand the benefits obtained after addition of these types of materials to the soil, an experiment involving the use of different manures and pyrolysis temperatures was performed. Five manure wastes were selected for this experiment: cattle manure (E); cattle manure mixed with straw (EP), chicken manure (G), chicken manure mixed with sawdust (GS) and pig slurry (PC). Unpyrolyzed samples were compared to biochars prepared at 300 and 500 • C. Relevant properties for agronomic purposes were determined, including pH, electrical conductivity, nutrient content, metal content, proximate analysis and carbon thermostability. Our results show that biochars tailored for different purposes can be prepared after a careful choice of feedstock and pyrolysis temperature.

“…In recent times, the use of biochar, in performing similar roles of improving water and nutrient retention capacity in the soil, while sequestering carbon, has received considerable attention (Ajayi et al, 2016;Dempster et al, 2012;Obia et al, 2016). Biochar is therefore widely promoted as an alternative soil amendment, particularly for coarse textured and poorly structured soils (Abel et al, 2013;Bruun et al, 2014;Mulcahy et al, 2013;Obia et al, 2016) and for mitigation of climate change related drought stress in agriculture (Liang et al, 2014).…”

A b s t r a c t. Changing climate is threatening rainfall regularity particularly in the semi-arid and arid regions; therefore, strategies to conserve water within their coarse-grained soils and to improve water use efficiency of crops are critical. This study compared the effectiveness of biochar and two types of clay materials in augmenting water retention and improving mechanical resilience of fine sand. The amendment of fine sand with woodchip-biochar and kaolinite (non-swelling clay) and Na-bentonite (swelling clay) improved the water retention capacity and interparticle bonding of the substrate depending of the rate of amendment and water content of the substrates. Na-bentonite was more effective at increasing water retention capacity at more negative matric potentials. Biochar was more effective at saturation due to the increased porosity, while kaolinite responds similarly to biochar. It is, however, shown that most of the water retained by the Na-betonite may not be available to plants, particularly at high amendment rate. Furthermore, the clay and biochar materials improved particle bonding in the fine sand with the Na-bentonite being more effective than biochar and kaolinite (in that order) in strengthening interparticle bonds and improving the resilience of fine sand, if the rate of amendment is kept at ≤50 g kg -1 .
