Converting oil palm empty fruit bunches into biochar is an alternative waste management method and has strong potential to improve N fertiliser use efficiency in agriculture. The aim of this study was to determine the effectiveness of oil palm empty fruit bunch biochar (EFBB) in improving recovery of 15N-labelled nitrogen fertiliser by maize (Zea mays L.) and leaching of mineral N and K. An experiment was conducted in a mini-lysimeter system with randomised complete block design layout and six replications under controlled environment in a rain shelter. Each mini-lysimeter was filled with 20 kg of sandy loam soil before adding EFBB (0, 5, 10 and 20 Mg ha?1). The N source used was (15NH4)2SO4 at 80 kg N ha?1 (2 at% 15N excess). Maize was irrigated to induce leaching every 4 days. Maize plant and soils were sampled 58 days after sowing (tasselling stage). Application of EFBB significantly reduced cumulative leachate volume and mineral N leaching. Soils applied with EFBB significantly improved 15N fertiliser recovery in maize and dry matter weight. This study shows that EFBB has the potential to be applied on highly weathered acidic soil as an amendment to improve fertiliser efficiency and crop growth. 相似文献

Exotic Acacia arabica, Acacia Auriculiformis, Eucalyptus camaldulensis, and Pinus caribaea, and indigenous Albizia lebbek, Cassia siamea, Chikrassia Tabularis, and Derris robusta were reforested in tropical semievergreen degraded forest lands to evaluate their capability of survival, growth, and biomass production in energy plantations. Three years after reforestation, significant variations in growth and biomass yield production were observed within each category of forest species. Both exotic and indigenous forest species had shown similar capability in the biomass production. Plant height was found a better predictor of biomass production than diameter at breast height. There have been improvements in soil properties under reforestation. Among the forest species, indigenous Cassia siamea and Derris robusta, and exotic Acacia auriculiformis were found highly adaptable, fast-growing, productive, and site improving, suitable for reforestation of degraded lands.

The advent of civilization has made humans dependent on plants for food and medicine, leading to the intensification of agricultural production. The intense cultivation of crops has resulted in the depletion of available nutrients from soil, thereby demanding the application of excess nutrients to soil to improve yield. Thus, mineral fertilizer discovery and application have, in many ways, contributed greatly to meeting global food demands. However, aside from the positive effects of mineral fer... 相似文献
