nanocomposite biochar via a novel developed functionalization method to recover phosphate as a potential fertilizer

Nima Kamali, Abdollah Rashidi Mehrabadi, Maryam Mirabi, Mohammad Ali Zahed

《环境科学与工程前沿（英文）》 2020年第14卷第4期 doi: 10.1007/s11783-020-1249-6

摘要： Abstract • Nanocomposites were prepared by adding dolomite to vinasse at different ratio. • Textural and morphological features of adsorbents were studied in detail. • CCD based RSM was used for investigation of P ion removal by nanocomposite. • The qm based on Langmuir model for modified vinasse biochar was 178.57 mg/g. • P loaded nanocomposite improved plant growth and could be utilized as P-fertilizer. The effectiveness of phosphate (P) removal from aqueous solutions was investigated by novel low-cost biochars synthesized from vinasse and functionalized with calcined dolomite. The vinasse-derived biochar, synthesized via pyrolysis at different temperatures, showed easy preparation and a large surface area. The novel vinasse biochar nanocomposites were prepared by adding dolomite to the vinasse biochars with different weight percentages (10, 20 and 30%). The characteristics of the prepared materials were identified for further understanding of the inherent adsorption mechanism between P ions and vinasse biochars. Vinasse-dolomite nanocomposite was very effective in the adsorption of P species from aqueous media. The effect of the operational factors on Vinasse-dolomite nanocomposite was explored by applying response surface methodology (RSM). According to RSM results, the optimum condition was achieved to be contact time 90 (min), 250 (mg/L) of P concentration and pH 7. Thermodynamic isotherm and kinetic studies were applied on experimental data to understand the adsorption behavior. The Vinasse-dolomite nanocomposite revealed preferential P species adsorption in the presence of co-existing anions. The P species could be recovered by 1.0 M HCl where the efficiency was not affected up to the fifth cycle. The P-loaded Vinasse-dolomite nanocomposite was successfully tested on a plant; it significantly improved its growth and proved its potency as a P-based fertilizer substitute.

Gu FENG, Jingping GAI, Xionghan FENG, Haigang LI, Lin ZHANG, Keke YI, Jialong LV, Yiyong ZHU, Li TANG, Yilin LI

《农业科学与工程前沿（英文）》 2019年第6卷第4期页码 341-347 doi: 10.15302/J-FASE-2019280

摘要：

A four-year project, entitled “The mechanisms of fraction transformation and high use efficiency of P fertilizer in Chinese cropping systems” commenced in 2017. The project was established to answer three key questions and looked at 17 cropping systems on ten soils. First, we asked what are the dynamics of transformation, fixation and mobilization of P fertilizers in soil-cropping systems? Second, what are the mechanisms of soil-crop-microbe interactions by which P fertilizer can be efficiently used? Third, how to manipulate the processes of P use in cropping systems? The targets of this project are (1) to explore the mechanisms of P fixation, the pathways of loss of P availability and the threshold of migration of fertilizer P in the field; (2) to uncover mechanisms by which soil legacy P is mobilized through root physiological and morphological processes and through arbuscular mycorrhizal fungi and P-solubilizing bacteria in rhizosphere and hyphosphere; (3) to estimate the biological potential of crops for high efficiency P absorption and use; (4) to innovate new approaches for improving the efficiency of P fertilizers. The outcomes will provide theoretical support for setting standards for limitation of P fertilizer application rate in the main cropping zones of China.

北方旱区农田水肥效应分析

高亚军,李生秀

《中国工程科学》 2002年第4卷第7期页码 74-79

摘要：

结合多年的田间试验研究，对前人诸多研究结果进行了总结和深入分析。结果表明：农田水肥效应大小与试验方法有关，田间试验与模拟试验得到的结论相反。主要原因在于研究中"水"的概念各不相同，从旱棚试验或盆栽试验的结果推断水肥效应与实际情况相距较大。多数情况下，养分亏缺仍是北方旱区作物增产的主要限制因子。灌水的效果取决于土壤底墒、生育期降水、土壤肥力及灌水时期等各种因素。在现有的水资源条件下，提高养分供应水平是北方旱区大部分农田作物增产的主要途径。加强夏闲期降水的蓄积、提高土壤底墒是冬麦区作物高产的重要条件。

摘要：

针对引进磷酸浓缩工艺生产磷铵的技术不适应我国矿产资源具体情况的难题，开发了料浆法磷铵生产工艺技术，已在21个省区布点推广建设了87套装置，形成生产能力279×10⁴ t/a的规模，占全国磷铵生产能力的60%。最近在贵州瓮福实施料浆法磷铵与引进的传统磷酸浓缩工艺联产的成功，为五大磷肥工程的改造提供了一条新的途径。

化肥过度施用的原因分析——基于销售商视角

连煜阳, 刘静, 金书秦, 刘宏斌, 武淑霞

《中国工程科学》 2018年第20卷第5期页码 112-119 doi: 10.15302/J-SSCAE-2018.05.017

摘要：

本文从肥料流通环节分析化肥过度施用的原因，分析肥料传统二级营销模式，了解肥料流通环节现状，利用肥料经销商的实地调研数据，对肥料经销商行为进行实证分析。研究发现肥料流通环节赊销现象严重，大大增加流通成本，使肥料价格虚高，肥料产品的宣传推广工作和农户赊销产生的资金风险增加了经销商的经营成本，经销商为保证盈利，会倾向于增加肥料推荐用量，导致农户过量施用化肥；此外，肥料经销商整体专业知识水平较低，参加农业技术培训可以使经销商更科学地推荐肥料用量。为此，建议提高肥料经销商市场准入门槛，优化对肥料经销商的培训，努力缓解肥料流通环节赊销压力。

关键词：肥料经销商赊销行为推荐用量

Phosphorus supply and management in vegetable production systems in China

Rui WANG, Weiming SHI, Yilin LI

《农业科学与工程前沿（英文）》 2019年第6卷第4期页码 348-356 doi: 10.15302/J-FASE-2019277

摘要：

Vegetable production systems involve high rates of chemical and organic fertilizer applications, leading to significant P accumulation in vegetable soils, as well as a decrease in P use efficiency (PUE), which is one of the key limiting factors in vegetable production. This review introduces the vegetable production systems in China and their fertilization status, and analyzes probable causes of overfertilization of vegetable fields. Poorly developed root systems and high P demand have led to the need to maintain much higher available P concentrations in the root zone for regular growth of vegetables, which might necessitate higher phosphate fertilizer input than the plants require. Research on strategies to improve vegetable PUE and the mechanisms of these strategies are summarized in this review. Increasing the P uptake by vegetables by supplying P during the critical growth stage and effectively utilizing the accumulated P by optimizing the C:P ratio in soils can substantially increase PUE. These advances will provide a basis for improving PUE and optimizing phosphate fertilizer applications in vegetable production through regulatory measures. In addition, some policies are recommended that could ensure the safety of vegetables and improve product quality. This review also aims to improve understanding of P cycling in vegetable fields and assist in the development of best practices to manage P reserves globally.
