AbstractAlthough black soldier fly frass fertilizer (BSFFF) is effective on crop performance, information on nitrogen (N) mineralization and nutrient release capacity of soils amended with BSFFF is lacking. This study utilized field incubation experiments to investigate the ammonification, nitrification, microbial populations, and quantities of nutrients released by soils amended with BSFFF and commercial organic fertilizer (SAFI) for a period equivalent to two maize cropping seasons. For the control treatment, no BSFFF or SAFI was added. Results indicated that most of the N in BSFFF amended soils was available in the ammonium form, while soils treated with SAFI had higher nitrate concentration. The BSFFF amended soils experienced shorter net immobilization periods of N (30–60 days) compared to SAFI treated soils (60–95 days). Increased rates of mineralization (3–10 times) and nitrification (2–4 times) were observed in soils treated with BSFFF during the second season of application. The BSFFF treated soils showed significantly higher N, phosphorus, and magnesium release than the control. Repeated application of BSFFF led to increased N release by three-folds in the soil. Furthermore, soil amendment with BSFFF increased the populations of bacteria and fungi, reduced soil acidity, and increased phosphorus (two-folds) and magnesium (two–four-folds) release than SAFI treated soils. Our findings highlight the crucial role of BSFFF in improving soil health by addressing the challenges of soil acidity, phosphorus fixation and nutrient mining, which is characteristic of most tropical soils.

Biosolids Application

The impact of repeated application of alkaline biosolids (sewage sludge) products over more than a decade on soil concentrations of nutrients and trace metals, and potential for uptake of these elements by crops was investigated by analyzing soils from farm fields near Oklahoma City. Total, extractable (by the Modified Morgan test), and water-soluble elements, including macronutrients and trace metals, were measured in biosolids-amended soils and, for comparison, in soils that had received little or no biosolids. Soil testing showed that the biosolids-amended soils had higher pH and contained greater concentrations of organic carbon, N, S, P, and Ca than the control soils. Soil extractable P concentrations in the biosolids-amended soils averaged at least 10 times the recommended upper limit for agricultural soils, with P in the amended soils more labile and soluble than the P in control soils. Several trace elements (most notably Zn, Cu, and Mo) had higher total and extractable concentrations in the amended soils compared to the controls. A radish plant assay revealed greater phytoavailability of Zn, P, Mo, and S (but not Cu) in the amended soils. The excess extractable and soluble P in these biosolids-amended soils has created a long-term source of slow-release P that may contribute to the eutrophication of adjacent surface waters and contamination of groundwater. While the beneficial effects of increased soil organic carbon on measures of “soil health” have been emphasized in past studies of long-term biosolids application, the present study reveals that these benefits may be offset by negative impacts on soils, crops, and the environment from excessive nutrient loading.

Purpose The purpose of this paper is to capture the status of implementation of Six Sigma in various manufacturing industries and also examine the success of the Six Sigma by using different performance indicators. Design/methodology/approach The methodology of critical review involves the selection and classification of 112 research articles on the implementation of Six Sigma in different manufacturing industries. The selected articles are categorized by the following: articles distribution based on the year of publication, publication database, various journals, contribution of authors, continent, scale of industry, implemented approaches, focused industry, tools and techniques used in phases of Six Sigma methodology, and performance indicators used in Six Sigma implementation. Then after, future scopes of research opportunities are derived based on significant findings. Findings The literature revealed that: Very few work was undertaken on the implementation of Six Sigma in various manufacturing industries like ceramic, paper, gems and jewelry, cement, furniture, stone, fertilizer, forging, paper and surface treatment industries. Most of the researchers have considered very few performance indicators to identify the improvement after Six Sigma implementation. But, there is no clue regarding overall improvement in different perspectives after the implementation of Six Sigma. The financial indicators, personnel indicators, process indicators and customer indicators are useful to measure the overall improvement after the implementation of Six Sigma in the manufacturing sector. Research limitations/implications The study was carried out on the implementation of Six Sigma methodology in various manufacturing industries, and various performance indicators were identified while implementing the Six Sigma methodology. Case studies pertaining to service industries were not covered here. Originality/value Very little research has been carried out to measure the overall success of implementing Six Sigma methodology in manufacturing industries. This paper will provide value to students, researchers and practitioners of Six Sigma by providing insight into the implementation of Six Sigma in manufacturing industries.

Care Demands

In this article, I participate in efforts to re-imagine soils as lively, complex, more-than-human ecologies, by turning to the largely sidestepped subject of spirituality in agriculture. Spiritual knowledge practices rarely sit comfortably alongside technoscientific, productivist accounts of soil health, and yet they can re-configure how soils are conceptualised and managed, with implications for relationships of care. Drawing on an extended period of learning with a Community Supported Agriculture project in south Wales, the article explores how care is cultivated through a non-conventional method of farming known as biodynamics, which incorporates astrological and spiritual principles. I suggest that biodynamic narratives and rituals encourage attentiveness to more-than-human agency and energy, to depth (not only underground but also above-ground influences of the air and celestial bodies), and to reciprocity between soil biota and humans. Biodynamic practices also make space for mystery, thereby resisting drives to measure and map, and offering possibilities for disrupting anthropocentric approaches to soil care. However, the example presented here also highlights how, despite biodynamic’s growing popularity, its spiritual elements have a tendency to be kept quiet, their presence sidelined by more familiar, secular, narratives. Nonetheless, I contend that if effective soil care demands more diverse knowledge practices than those that are currently obliterating critical soil communities at an alarming rate, then there can be much to learn from a touch of magic.

As a continuation of the previous paper by the same authors, this article presents a critical analysis on how companies practicing world class manufacturing (WCM) have to modify their ways of measuring performance in their efforts to attain manufacturing excellence. In doing so, implications of implementing WCM methods in measuring company performance are elaborated. While business performance depicts a company's ability to satisfy customers' needs, hence customers mostly perceive their measurement; manufacturing performances can be used as yardsticks to assess the effectiveness of its resources to satisfy the customer. This paper proposes 15 manufacturing performance as key performance indicators for a company pursuing WCM.
