What is Composting Processes and Applications?

Composting processes involve microbial decomposition of organic wastes into stable humus-like material used to enhance soil fertility and plant growth in agriculture.

Research examines feedstock optimization, decomposition kinetics, maturity indicators, and applications in crop production. Over 300 papers document effects on soil properties and yields, with key studies on oil palm waste and biochar-compost blends. Foundational work from 2013-2014 established cow dung and sago pith compost impacts on maize and taro (Tanimu et al., 2013; La Habi et al., 2014).

Key Challenges

Why It Matters

Compost from agricultural wastes recycles nutrients, reducing chemical fertilizer needs by 20-50% in trials on oil palm seedlings and shallots (Rosenani et al., 2016; Lasmini et al., 2018). Biochar-compost mixes improve soil water retention and maize yields on drylands by enhancing microbial activity (Situmeang et al., 2015; Barus, 2016). These practices support sustainable farming, cutting waste and boosting crop resilience in tropical wetlands (Kartika et al., 2018; Lakitan et al., 2018).

Key Research Challenges

Pathogen Reduction in Compost

High temperatures during composting must exceed 55°C to eliminate pathogens, but inconsistent aeration leads to survival in piles (Yamika et al., 2018). Maturity testing via C/N ratios below 20:1 ensures safety, yet field variability complicates standards. Recent studies highlight cow manure risks under saline stress (Yamika et al., 2018).

Feedstock Nutrient Optimization

Balancing C/N ratios (25-30:1) across wastes like oil palm bunches prevents immobilization or ammonia loss (Ichriani et al., 2018). Bokashi fermentation aids but requires microbial inoculants for consistency (Lasmini et al., 2018). Ultisol trials show phosphate solubilizers boost P uptake by 15-25% (Ichriani et al., 2018).

Scalable Maturity Indicators

Germination index >80% and respirometry indicate maturity, but lab methods hinder farm adoption (Rosenani et al., 2016). Biochar addition stabilizes compost but alters indicators like electrical conductivity (Kartika et al., 2018). Standardization remains elusive across tropical soils (Zhao et al., 2019).
