“…Biochar has higher stability characteristics against decomposition and is able to absorption and water well than other organic materials, due to larger surface area and negative surface [14], [15]. Biochar bamboo has a highly microporous structure, with adsorption efficiency about ten times higher than traditional wood biochar [16]. Table 1 shows that biochar has a pH, C/N, K, Ca, and Mg relatively higher than in compost, otherwise compost has EC, C-organic, N-total, P-available, Na, and relative water content higher than biochar.…”

This study aims to obtain the best dose or optimum dose of biochar, compost, and phonska in improving the yield of corn in the dry land. This experiment used a randomized block design (RBD) 3 replication with a nested experiment, where the dose factor was nested in each type of fertilizer. The treatment factor consisted of 3 types of fertilizer (J), namely: biochar (B), compost (K), and phonska (P) with 3 fertilizer doses (D) and a control as a comparison. The results showed that the dosage of biochar 10 t ha -1 could increase the highest total oven dry weight of 509.31 g, which increased by 23.95% when compared with without biochar of 410.90 g. Composting doses of 20 t ha -1 can yield the highest total dry weight of the oven of 525.05 g, an increase of 27.78% when compared with no treatment of 410.90 g. Phonska dosage of 300 kg ha -1 can give the highest yield of the dry weight of the highest total plant oven of 563,91 g, increasing by 37,24% when compared with without treatment equal to 410,90 g. The results of this study obtained the optimum dose of biochar 10.52 t ha -1 , compost 20,22 t ha -1 , and phonska 313,37 kg ha -1 that can be used to improve a yield of the corn plant in the dry land.

“…However, plants were not present in this incubation and it can be expected that in a field trial situation poultry litter applications (with acidified biochar) timed to enhance plant N uptake would offset synthetic fertiliser inputs. The role of NH 3 uptake, i.e., reduced NH 3 volatilization and loss, has also been postulated or observed in composting experiments [10,91,92]. Clearly there is role for biochar in capturing NH 3 and for this captured N to be released upon plant demand.…”

oxide (N 2 O) were short-term in nature and found emission reductions, but long-term studies are lacking, as is mechanistic understanding of reductions. Stable N isotopes have a role in elucidating biochar-N-soil dynamics. There remains a dearth of information regarding effects of biochar and soil biota on N cycling. Biochar has potential within agroecosystems to be an N input, and a mitigation agent for environmentally detrimental N losses. Future research needs to systematically understand biochar-N interactions over the long term.

“…Secondly, it can change the pH of the soil affecting the availability of the crop nutrients present [30,31]. Thirdly, it can retain nutrients from fertilisers added to biochar amended soil through mechanism such as adsorption and its CEC, apparently reducing their leaching [31][32][33][34], and fourthly, it can alter the amount of ammonia (NH3) and nitrous oxide (N2O) released by soils, affecting soil nitrogen content [30,32,[35][36][37][38][39]. Lastly, biochar may affect nutrients in the soil through changes in microbial and fungal metabolism and diversity which are integral in determining crop nutrient availability and uptake [40][41][42].…”

Keywords: Biochar nutrient availability water availability soil fertility water holding capacity Methodology CAB Abstracts and Science Direct (keywords biochar, nutrients, water) along with sources at the University of Greenwich were searched to obtain up to date research papers. Personal collections of the corresponding author were obtained from various sources over the past 5 years were also used.This material has been published in CAB Reviews (2014) AbstractBiochar has consistently been proposed as a way of improving soil fertility by increasing nutrient and soil water availability. This review critically investigates recent literature, focussing particularly on these agronomic aspects of biochar. We clarify the differences between biochar made from plant (plant derived biochar, PDB) and animal feedstock (animal derived biochar, ADB) and show how pyrolysis temperature affects biochar properties. We also tabulate crop yield data against production variables using recent field and greenhouse studies. We find evidence to suggest that ADB supplies many more nutrients than PDB and that, in general, biochar can improve nutrient availability indirectly through changes in pH, CEC, soil structure, improved fertiliser efficiency, decreased nutrient leaching and may effect nutrient availability by changing nitrogenous gas release and by changing the soil microbial community, which under some circumstances translates into short term, increased crop yield. Few studies however show complete nutrient, especially N budgets and elaborate on the underlying mechanisms of interaction, especially with regards to microbial induced changes. Also the longevity of the different beneficial effects is questionable as most studies are less than a year long.A synopsis of the literature concludes that biochar application promotes soil water availability, particularly in soils which are degraded or of low quality. Despite this conclusion it is hard to find studies that have adopted methodologies which are fully appropriate to support this notion such as available water capacity and how this changes in response to crop uptake and soil drying. We conclude that the variability in biochar due to variable feedstock and pyrolysis process, as well as particle size and application method, necessitates and also enables production of specific purposedriven biochars to benefit particular aspects of crop production.
