“…These by-products also can be seen in Table 1. Bio-based fertilizers hold the advantage of recycling nutrient-rich side stream and using less energy and nonrenewable resource consumption during manufacture compared to mineral fertilizers (Jensen et al, 2020).…”

“…Then, life cycle sustainability assessment is needed to evaluate the potential benefits and consequences of BBFs as compensation of mineral fertilizers through LCC (techno-economical), LCA (environmental), and S-LCA (socio-economical). The environmental impact of a bio-based fertilizer will depend on the type of waste in question, coupled with the treatment technology and utilization of the outputs as a result (Jensen et al, 2020). Furthermore, the use of BBFs needs to be observed not only in the short time but also in the long term (15-20 years) to determine the environmental impact and to determine safe doses of BBFs (Dubis et al, 2020).…”

Opportunities and challenges of bio-based fertilizers utilization for improving soil health

Bio-based fertilizers (BBFs) have been promoted as a solution to help manage bio-waste problems and improve soil health conditions. Their potential is to replace mineral fertilizers due to nonrenewable energy dependency and the accumulation that threatens environmental issues. Currently, laboratory and field-based literature have been growing since European Union (EU) looks BBFs as the future of agriculture bio-based products. Nevertheless, it is worth to summarizing the results on a regular basis. The added value of this work is to study the opportunities of bio-based fertilizer utilization to sustain plant productivity and investigate the challenges to water footprints and human health. This study found that contamination of heavy metals and pathogens is the main problems of BBFs implementation which need more attention to develop the technology process including the environmental risk assessments. Furthermore, compared to mineral fertilizers, BBFs have obstacles to getting social acceptance due to the challenges of transportation and production cost, the concentration of nutrients, matching crops, and policy framework. To sum up, BBF is a long-run scheme that should be started to tackle global issues since the potency as energy alternative sources to support the circular economy paradigm.

“…Management measures focus on the efficient use of nutrients and C, by incorporating composition, plant-availability, C stability, and risk of nutrients losses in fertilization strategies. Technological measures to reduce nutrient emissions include changes in livestock housing systems and manure storage, the use of manure treatment techniques, and the use of precision and low emission application techniques of manures (Chadwick, 2005;Hou et al, 2015;Bougouin et al, 2016;Jensen et al, 2020;Van der Weerden et al, 2021). Structural changes in agriculture, such as the reduction or reallocation of livestock numbers, are also options to improve nutrient and C management and reduce emissions from organic resources (Van Grinsven et al, 2018;Kim et al, 2023).…”

Recycling of organic resources into agriculture has the potential to greatly increase nutrient use efficiency and improve soil carbon balance, but improper management can have adverse effects on the environment. Agriculture therefore faces large challenges to increase yields while decreasing these emissions to the environment. In this paper, we review (i) the availability and composition of organic resources, (ii) their agronomic value and risk of emissions, (iii) potential measures to reduce their emissions, and (iv) future challenges to support farmers and policy makers. The total amount of organic resource applied to soil amounted on average 41 kg nitrogen per ha agricultural land, 9 kg phosphorus per ha, and 456 kg carbon per ha in EU-27 + UK in 2017. Solid pig and cattle manures and cattle slurry are the most used organic resources. The availability of new organic resources from food processing, sewage sludge, municipal bio-wastes, and upcoming manure treatment techniques as fertilizer or soil conditioner is expected to strongly increase over the coming decade. Insight is needed into the composition of organic resources, the plant-availability of nutrients, the degradability of organic matter and the presence of contaminants. Measurement techniques become available to characterize soils, manures, crops, and emissions to the environment. However, the interpretation, and integration of data, and recommendations to farmers and policymakers using large amounts of data is expected to become more and more challenging. Many measures are available to improve nutrient and carbon management and to reduce emissions, including proper application, technological measures and structural changes in agriculture. For many measures, there is a risk of trade-offs that could lead to pollution swapping at different scales. We should focus on finding synergies between measures and no-regret management choices to develop effective mitigation strategies. The main future challenge for managing organic resources in agriculture is the development of an integrated nutrient management approach, including (i) the characterization of organic resources, their agronomic value and their environmental risks, (ii) knowledge of potential synergies and trade-offs between management measures, and (iii) implementation of this knowledge into decision support tools, models and legislation to support farmers and policy makers.

“…The conversion of mineral fertilizers to organic ones is based on soil improvement and the reduction of negative environmental impacts. Rational use of fertilizers can reduce unwanted climate changes [22,24]. Reference [25] states that due to slow mineralization, organic fertilizers are leached into water more slowly than mineral fertilizers, and thus water pollution with nitrogen compounds is lower.…”

Application of Granular and Non-Granular Organic Fertilizers in Terms of Energy, Environmental and Economic Efficiency

Granular organic fertilizers have been increasingly used in agriculture due to the longer delivery of nutrients to plants and the milder impact on the environment. The aim of this study was to determine the energy, environmental and economic efficiency of granular and non-granular organic fertilizers. Four technological scenarios of organic fertilizer use were used for comparative assessment: (1) manure fertilization (16.0 t ha−1), (2) manure fertilization (30.0 t ha−1), (3) manure pellet fertilization (2.0 t ha−1), and (4) fertilization with meat and bone meal pellets (0.7 t ha−1). Experimental studies using the mass flow method of laser spectroscopy were performed to evaluate the comparative environmental impact of granular and non-granular organic fertilizers. Economic assessment was performed for mechanized technological operations of loading, transportation and distribution of organic fertilizers, estimating the price of aggregates used and fuel consumed, the costs of individual technological operations and other indirect costs. The results showed that for mechanized technological operations, when fertilizing with granular organic manure and meat and bone meal fertilizer, energy consumption is 3.2 to 4.0 times lower compared to fertilization with manure. The average ammonia (NH3) emissions from granular organic fertilizers were found to be six times lower than from non-granular organic fertilizers. The lowest costs for mechanized works were incurred when using meat and bone meal pellets, the highest economic benefits of organic fertilizers by elements was when using manure 30 t ha−1, and the highest costs for organic fertilizers were incurred when using manure pellets.
