“…The obtained digestate after anaerobic digestion could be used as an organic fertiliser for the fields of the farm [ 28 , 29 , 30 , 31 ]. The composition of the mixture of fish co-streams with cattle manure should be formed as nutrients for plant fertilisation [ 32 , 33 ]. Co-digestion of fish co-streams with cattle manure could improve the energy efficiency of biogas plant and fertilisation quality of the final digestate [ 34 , 35 ].…”

This study evaluates the possibility of recovery of high-quality valuable fish oil and proteins from fish co-streams by traditional means or a combination of several technologies. A techno-economically feasible and sustainable zero-waste process is needed for full utilisation of this co-stream’s potential. This study aims to determine the energy efficiency and economic feasibility of four different zero-waste bio-refineries based on salmon filleting co-streams. The study covers four concepts: (I) biogas and fertiliser production from salmon co-streams, (II) fish silage production, (III) thermal processing of salmon co-streams for producing oil, protein concentrate, and meal, and (IV) novel two-stage thermal and enzymatic process for producing high-quality oil and protein hydrolysate, while the solid residue is converted to biogas and fertilisers. Monte Carlo simulation is used to evaluate uncertainties in economic evaluation. The results show that the two-stage processing of fish co-streams leads to recovery of both high-quality marine oil and proteins, showing the largest profitability and return on investment during the economic analysis. It is a more tempting option than the currently used thermal treatment or traditional silage processes. The possibility of producing food-grade fish protein hydrolysate is the biggest benefit here. Concepts studied are examples of zero-waste processing of bioproducts and illustrate the possibilities and benefits of fully utilising the different fractions of fish as fillets, oil, protein, fertilisers, and energy production.

“…The regular supply of nutrients during the cropping period, close synchronization between nutrient release/crop demand and improvements in the important properties of amended soils could be possible causes for the considerable increase in growth and yield obtained with saffron under UN + PM treatment, as observed by Ghanbarian et al (2008). Other studies (Enujeke 2013, Adeyeye et al 2107, Zydelis et al 2019) also showed that the soil application of organic materials, particularly PM, has the potential to sustain crop yields and improve soil properties and fertility. Moreover, Koocheki et al (2019) discussed the positive effects of organic matter amendments or content on stigma and daughter corm yield of saffron.…”

“…The yield attributes serve as reliable indicators of saffron yield, and our findings were in line with those of Ewulo et al (2008) and Koocheki et al (2019), who opined that crop yields were increased through PM application because of its leading role in enhancing nutrient content and uptake. Increased growth and yield attributes (SY and CY) in the combined N and PM treatments could be the result of microbial N mineralization from the PM providing N during the whole growing period in proportion to crop requirement (Zydelis et al 2019).…”

Integrated nutrient management (INM) is an environment friendly and ecologically adoptable approach of plant nutrition to sustain crop productivity and maintain soil fertility of fragile agricultural ecosystems. A three-year field experiment on saffron was conducted involving 12 fertilization regimes: control; urea (UN) = 100 kg•ha -1 ; poultry manure (PM) = 100 kg•ha -1 ; farmyard manure (FYM) = 100 kg•ha -1 ; PM 50 + FYM 50 ; UN 75 + PM 25 ; UN 50 + PM 50 ; UN 25 + PM 75 ; UN 75 + FYM 25 ; UN 50 + FYM 50 ; UN 25 + FYM 75 ; and UN 50 + PM 25 + FYM 25 . Results showed that PM alone and combined with 50% UN (UN 50 + PM 50 ) were effective compared to the controls in increasing the number of flowers (58%), flower dry weight (59%), stigma length (70%), dry weight of stigma (40%), number of daughter corms plant -1 (35%), and corm diameter (71%) of saffron over years. In addition, the same treatment combination increased corm weight (96%), corm yield (96%), and stigma yield (35%) over controls across the years. This treatment combination was followed by UN 50 + PM 25 + FYM 25 , while UN 50 alone did not perform at par to the rest of the fertilization regimes. These results showed that UN 50 + PM 50 might be developed as potent strategy for boosting the growth and yield (stigma and daughter corms yield) of saffron in temperate climatic conditions.

“…The chemical composition of plant-based organic fertilisers. Plant nutrition in arable farms can be enriched by using organic fertilisers, although their function and the satisfaction of crop demand are highly dependent on the type or chemical composition (Chen et al, 2018;Žydelis et al, 2019). The fresh red clover mass can accumulate a high N amount (Brozyna et al, 2013;Frøseth et al, 2014;Gaudin et al, 2013), but the process of N accumulation and release is difficult to predict and control.…”

The effect of plant-based organic fertilisers on the yield and nitrogen utilization of spring cereals in the organic cropping system. Zemdirbyste-Agriculture, 107 (1): 17-24. AbstractLegumes in stockless cropping systems are the key elements for nitrogen (N) supply, nutrient cycling, crop productivity and soil fertility. Field experiments were conducted in 2015-2017 on the loam and clay loam soil at two experimental locations in Lithuania. The aim of the research was to study the two-year effect of technologically processed plantbased organic fertilisers on the mineral N (N min ) and mobile humic substances in the soil, also the productivity and N accumulation by spring cereals in the organic cropping system. The following fertilisers were investigated: fresh mass of red clover, fermented red clover mass, fermented pea and wheat mass, composted red clover and wheat straw mass and granulated cattle manure. Fresh and fermented red clover mass was found to be rich in N and potassium (K), while composted red clover and straw mass was rich in phosphorus (P). Soil N min was significantly increased by the fresh red clover mass in the 1 st experimental year and by fermented red clover mass in the 2 nd year, and significantly correlated with carbon to nitrogen ratio (C:N) of plant-based fertilisers. In the 1 st year, the grain yield of spring wheat was significantly increased using fresh red clover mass and granulated cattle manure; however, in the 2 nd year fermented red clover mass increased the yield of spring barley grain the most. During the two years of plant-based organic fertiliser use, in both experimental sites most of the N yield in cereal grains and straw was accumulated using fresh red clover, fermented red clover and granulated cattle manure fertilisers. Comparison of the two experimental sites revealed that the effects of plant-based fertilisers on the productivity of cereals and changes in soil chemical compounds were more apparent in the N min low loam soil than in the N min richer clay loam soil. The effect of fermented red clover and granulated cattle manure was comparable; however, greater improving effect was exhibited by the fermented red clover in the loam soil and by granulated cattle manure in the clay loam soil.
