“…Biochar seems to be one of the most effective materials reducing soil K losses in regions with high rainfall (Widowati and Asnah 2014). Several studies reported soil exchangeable K increase after biochar application.…”

“…Several studies reported soil exchangeable K increase after biochar application. This impact was in part due to a direct supply of K from biochar (Zong et al 2016) or by indirect improvement in fertilizer use efficiency by adsorption of nutrients on exchange surfaces thus reducing leaching loss (Widowati and Asnah 2014).…”

Purpose This study aimed to assess the impact of two biochars applied at the rate of 15 t ha −1 on physico-chemical parameters of an oxisol in Cameroon. Methods The biochars were made from slow pyrolysis (~ 300 °C, 4 h) of eucalyptus tree bark and corncobs and then incorporated into the top 15 cm of the soil with or without straw. The soil tillage mode was either flat plots or furrows and ridges. Soil porosity, bulk density, saturated hydraulic conductivity, available water content, pH, nitrogen, potassium, phosphorus, cation exchange capacity and electrical conductivity were analysed before biochar application, then 6 and 12 months after. Results None of the measured soil physical parameters were affected by the presence or type of biochar. The total porosity was lower during the second production period compared to the first, while available water content and van Genuchten parameters increased during the second production period. No significant difference was observed between soil nitrogen, phosphorus, potassium, cation exchange capacity and electrical conductivity of control and treated plots. Conclusion We recommend that straw be pyrolysed and the resulting biochar incorporated into soil instead of burying straw (as is actually done in furrow and ridges tillage mode).

“…Application of biochar increased 54,78% water storage, while that without biochar application was 50.86%. As reported by Widowati and Asnah (2014) leaching of K from litter biochar affected the amount of water drained which tended to decrease with increasing rates of biochar. The use of biochar can improve soil porosity (Widowati et al, 2012;Steiner et al, 2007).…”

“…However, under tropical conditions, organic matter is rapidly oxidized and added bases are rapidly leached (Tiessen et al, 1994). On the other hand, application of biochar has been proved to reduce nutrient leaching (Downie et al, 2009), and after incorporation into soil, biochar improves soil fertility (Lehmann et al, 2003;Steiner et al, 2007), increase the efficiency of N fertilizer (Widowati et al, 2012), and reduce the use of K fertilizers in Inseptisols (Widowati and Asnah, 2014). Biochar as a soil amendment is potential for improving crop yields and quality of degraded soils.…”

Nutrient leaching is often a problem especially in tropical areas with soil fertility constraints. This study aims to reveal the effect of biochars on leaching and uptake of nitrogen and potassium from degraded soils cultivated with maize. Each of three types of biochar originated from rice husk, wood, and coconut shell, was applied to the soil placed in PVC tube at four rates (0, 15, 30, and 45 t/ha). Maize was then planted in each pot. All pots received urea (135 kg N/ha), SP36 (36 kg P 2 O 5 /ha), and KCl (110 kg K 2 O/ha). Twelve treatments (three biochars and four application rates) were arranged in a factorial randomized block design with three replicates. Results of the study showed interaction effects of biochar materials and biochar rates on nitrate leaching (except on day 1 to 30) and potassium, N uptake, and plant growth. On day 1-30, leaching of nitrate and potassium was reduced by biochar application. The lowest nitrate leaching was observed at rate of 45 t /ha of wood biochar, while application of 45 t coconut shell biochar / ha resulted in the highest K leaching. Beside, wood biochar resulted in a similar nitrate leaching with that of coconut shell biochar, but nitrate leaching increased with increasing rate of rice husk biochar on day 30-60. All biochar materials yielded similar potassium leaching at all rates. Application of 45 t rice husk biochar /ha resulted in the best maize growth.

“…N, P and K. When these wastes are used to produce biochar, they bring about an opportunity to be used as a sustainable soil amendment. It may help to avoid further reduction of soil organic carbon (Gaskin et al, 2008) and prevent increased fertilizer-use (Widowati and Asnah, 2014). Pyrolysis is the combustion of organic waste materials in complete absence or partial presence of oxygen, leading to the formation of carbon-rich char (biochar) (Thies and Rillig, 2009).…”

In a field trial, Dalbergia sissoo biochar was used to investigate its potential for improving growth, yield and nutrient recovery of wheat (Triticum aestivum L.), at varying fertilizer rates under calcareous soil. Two biochar levels (0.0 and 1.0% of soil weight) were used along with five fertilizer rates i.e. 0, 25, 50, 75 and 100% of recommended inorganic fertilizer dose (RFD). Seeds of wheat cultivar Faisalabad-2008 were sown in the field using 2 factorial-randomized complete block design. At reduced fertilizer rates, biochar application improved plant growth parameters i.e. plant height, spike length, number of tillers hill −1 and grain yield over the respective treatments having inorganic fertilizer without biochar. Regarding nitrogen (N), phosphorus (P) and potassium (K) content, the highest statistical results were achieved at reduced fertilizer doses along with biochar application i.e. N and P content in wheat straw and grain at 50% RFD, straw N and P uptake at 75% RFD, grain N and K uptake at 50% RFD and grain P uptake at 75% RFD. The highest N, P and K recovery was calculated in the treatments having 50% RFD + biochar with 95%, 25% RFD + biochar with 38% and 25% RFD with 117%, respectively. In comparison with control treatment (without fertilizer and biochar), biochar application improved soil CEC up to 40%. With biochar application, no any significant change was observed in other soil chemical properties i.e. pH and EC. The results suggested that 1.0% biochar along with reduced fertilizer doses, could be effectively used to improve wheat growth, yield, nutrient content and nutrient uptake under field condition. Moreover, 1.0% biochar along with 75% of RFD can be effectively used in place of 100% RFD to get the highest yield.
