Abstract

ABSTRACT Biochar, a carbon-rich solid produced from biomass pyrolysis, has attracted growing interest as a fertiliser ingredient due to its ability to non-permanently retain nutrients. A greenhouse pot experiment was set up to compare three commercial organo-mineral fertiliser formulations (NPK, NP and K) with the corresponding formulations containing a slow-pyrolysis wood biochar (NPK+B, NP+B and K+B) (6 replications each). Nutrient leaching as well as crop growth and nutrient uptake was monitored using barley as model species. Nutrient leaching was slowed down in the NPK+B compared to the NPK fertiliser. The most responsive ions were nitrate and potassium, whose leaching during the two first weeks was reduced by 28% and 22%, respectively, while this trend reversed from the third week on. One plausible explanation would be a microbial nutrient immobilisation mediated by the concurrent NPK and biochar habitat provision. NPK+B significantly enhanced barley straw biomass (23.43% increase respect to NPK), whereas all the biochar-based fertilisers showed increases in nutrient content and export (involving potassium, sulphur, calcium and manganese), possibly indicating that biochar acted as a nutrient source. These results provide some evidence of the potential use of the studied biochar in biochar-based fertilisers to meet nutrient availability with plant demands.

有机无机肥料中添加生物炭延缓养分淋失，提高大麦养分含量

摘要生物炭是一种由生物质热解产生的富含碳的固体，由于其非永久性保留营养物质的能力，作为一种肥料成分越来越受到人们的关注。建立了温室盆栽实验，将三种商业有机矿物肥料配方（NPK、NP和K）与含有缓慢热解木材生物炭的相应配方（NPK+B、NP+B和K+B）进行比较（每个配方重复6次）。以大麦为模式物种，监测了养分浸出以及作物生长和养分吸收。与NPK肥料相比，NPK+B的养分浸出速度减慢。反应最灵敏的离子是硝酸盐和钾，在最初的两周内，它们的浸出量分别减少了28%和22%，而这一趋势从第三周开始逆转。一个合理的解释是，同时提供NPK和生物炭栖息地介导了微生物营养物的固定。NPK+B显著提高了大麦秸秆的生物量（相对于NPK增加了23.43%），而所有生物炭基肥料的营养含量和出口量（包括钾、硫、钙和锰）都有所增加，这可能表明生物炭是一种营养来源。这些结果为所研究的生物炭在生物炭基肥料中的潜在用途提供了一些证据，以满足植物需求的养分可用性。

期刊介绍： rchives of Agronomy and Soil Science is a well-established journal that has been in publication for over fifty years. The Journal publishes papers over the entire range of agronomy and soil science. Manuscripts involved in developing and testing hypotheses to understand casual relationships in the following areas: plant nutrition fertilizers manure soil tillage soil biotechnology and ecophysiology amelioration irrigation and drainage plant production on arable and grass land agroclimatology landscape formation and environmental management in rural regions management of natural and created wetland ecosystems bio-geochemical processes soil-plant-microbe interactions and rhizosphere processes soil morphology, classification, monitoring, heterogeneity and scales reuse of waste waters and biosolids of agri-industrial origin in soil are especially encouraged. As well as original contributions, the Journal also publishes current reviews.
