Graphical abstract The residual slurry obtained from the anaerobic digestion (AD) of biogas feed substrates such as livestock dung is known as BGS. BGS is a rich source of nutrients and bioactive compounds having an important role in establishing diverse microbial communities, accelerating nutrient use efficiency, and promoting overall soil and plant health management. However, challenges such as lower C/N transformation rates, ammonia volatilization, high pH, and bulkiness limit their extensive applications. Here we review the strategies of BGS valorization through microbial and organomineral amendments. Such cohesive approaches can serve dual purposes viz. green organic inputs for sustainable agriculture practices and value addition of biomass waste. The literature survey has been conducted to identify the knowledge gaps and critically analyze the latest technological interventions to upgrade the BGS for potential applications in agriculture fields. The major points are as follows: (1) Bio/nanotechnology-inspired approaches could serve as a constructive platform for integrating BGS with other organic materials to exploit microbial diversity dynamics through multi-substrate interactions. (2) Advancements in next-generation sequencing (NGS) pave an ideal pathway to study the complex microflora and translate the potential information into bioprospecting of BGS to ameliorate existing bio-fertilizer formulations. (3) Nanoparticles (NPs) have the potential to establish a link between syntrophic bacteria and methanogens through direct interspecies electron transfer and thereby contribute towards improved efficiency of AD. (4) Developments in techniques of nutrient recovery from the BGS facilities’ negative GHGs emissions and energy-efficient models for nitrogen removal. (5) Possibilities of formulating low-cost substrates for mass-multiplication of beneficial microbes, bioprospecting of such microbes to produce bioactive compounds of anti-phytopathogenic activities, and developing BGS-inspired biofertilizer formulations integrating NPs, microbial inoculants, and deoiled seed cakes have been examined.

“…Digestate, for example, can be used for soaking seeds (e.g., faba beans), having a positive effect on seed germination and seedling growth (Zhao et al, 2014). A study of Kupper et al (2006), furthermore, showed that the digestate can be used in disease and pest control in case of Citrus black spot disease.…”

Improving manure management at smallholder dairy farms in Indonesia: a multi-level analysis

the N-P excretion of dairy cattle is first needed. Quantification of N-P is crucial because both managed and unmanaged N-P lead to environmental emissions. Mathematical models are often used to predict N-P excretion of dairy cows. Most N-P excretion models, however, are developed for dairy farming systems in developed countries, and not for smallholder systems in Indonesia. A generic model to predict N-P excretion of dairy cows on smallholder dairy farms is not available.Information on N-P excretion can subsequently be used to estimate the flows and losses of nutrients on smallholder dairy farms. Flows and losses in dairy farming systems, however, may also depend on manure management system (MMS). Different MMSs exist in smallholder dairy farms in Indonesia (de Vries et al., 2017). So far, it is unknown how nutrient flows and losses differ across systems.Furthermore, it is unknown to what extent the dairy sector contributes to the pollution of the Citarum river, being the longest river in the province of West Java (Garg et al., 2018;Yoshida et al., 2017; Kerstens et al., 2013). Though the dairy sector is presumed to contribute to the pollution of this river, its exact contribution is so far unknown.Whereas estimating N-P losses is relevant with regard to local environmental impacts such as eutrophication and contamination of drinking water, climate change happens at a global scale, and quantification of GHGE therefore requires a value chain level approach. So far, most studies that assessed GHGE on smallholder farms in tropical regions used data collected at one particular moment in time (i.e., cross-sectional observation) or used data based on farmers' recall. The climate of Indonesia, however, is characterized by a dry and a rainy season, and dairy farmers adapt their practices to these seasons, mainly with regard to feeding and manure management. Such seasonal differences can be an important source of variability in estimates of the GHGE-intensity (GHGEI)i.e. the GHGE per kg milk. Longitudinal studies could provide insight into the impact of seasonal differences on GHGEI estimates, and into the implications of the number of farm visits on the accuracy of the estimate but are currently not available.In order to reduce GHGE from dairy farms, insight into the impact of mitigation strategies is needed.An important mitigation strategy proposed is increasing milk yield per cow. This strategy is promising General introduction | 13 3 1 because there is a non-linear negative association between milk yield and GHGE per unit of milk output (Gerber et al., 2011). However, this strategy often appears difficult to adopt at smallholder dairy farms because it requires a combination of improving feed supply and quality, improving animal health and cow fertility, and improving genetic potential. Therefore, alternative strategies for mitigating GHGE are required. So far, however, strategies to reduce GHGE from smallholder dairy farms in Indonesia beyond milk yield increases are unexplored.Proper manure management is presently no...
