Summary: The study found that the application of organic manures, such as poultry and pig manure, significantly reduced the exchangeable acidity and readily soluble aluminum content in the soil, while increasing soil pH, organic carbon content, and microbial biomass carbon. The use of poultry and pig manure also promoted the improvement of soil fertility, enhancing plant chlorophyll content, root growth, fruit yield, and harvest index.

Summary: Organic amendments have significant effects on plant growth and soil microbial communities, with vermicompost having the best impact on plant growth; they increase soil porosity and water holding capacity, but delay plant maturation and decrease plant biomass; bacterial communities are more affected by organic amendments, showing distinct microbial communities for different treatments.

Summary: The objective of this paper is to evaluate the yield, quality and unit production cost of broccoli grown under green manure, vermicompost and chemical fertilization. The combined effect of Ve and V increased the yield and quality of the broccoli curds. As a result of economic analysis, approximately twice the net profit difference emerged in VeV treatment compared to other treatments.

Summary: The study investigated the composting of beef cattle manure using sawdust or recycled compost as a bulking agent for managing clopyralid risk. Clopyralid concentration did not change during composting in the thermophilic phase, but increased when recycled compost was repeatedly used, leading to clopyralid accumulation. A model was established to explain clopyralid accumulation ratio, providing a way to control excessive clopyralid accumulation during composting.

Summary: Organic amendments are beneficial for farmers as they improve maize performance and yield, while also enhancing soil physical properties. The effects of compost and vermicompost were similar under different moisture stress conditions, with no added benefits observed when using vermicompost instead of compost.

Summary: Soil amendment with animal manure and vegetable waste composts effectively reduced Cd mobility and accumulation in plants. Both composts showed similar effectiveness in reducing Cd translocation, but animal manure compost performed better for maize growth in polluted soil.

Summary: The study found that adding biochar significantly reduced potential ammonia oxidation rates during composting. Structural equation model analysis showed that temperature and pH influenced the activity of AOB, which in turn affected nitrification in CM. Temperature and NO2--N were identified as the main factors influencing nitrification in CM and CMB.

Summary: Newly isolated ammonia-oxidizing bacteria (AOBs) showed effectiveness in promoting the degradation and humification process of cattle manure compost. Among them, MT-AOB-2-4 had the most significant impact, enhancing bacterial activity and promoting the formation of humic substances. High abundance of Bacillaceae, amoA, and nirS were correlated with humification factors.

Summary: The practice of incorporating organic manures and fermented liquid biofertilizers of different origins and compositions can supply valuable nutrients to the soil. The combination of organics and FLONFs contributed significantly to soil enzyme activity, microbial population, and brinjal yield.

Summary: The objective of this study was to examine a novel approach to designing organic fertility amendments by blending mature vermicompost and thermophilic compost. The results showed that blending vermicompost and thermophilic compost can enhance the availability of nitrogen, phosphorus, and potassium in the fertilizer. Electrical conductivity measurements suggest that blending affects the compost within three days of starting the incubation. In addition, the activity of enzymes in the blend was linearly and positively related to the fraction of vermicompost added. Blending mature composts with differing properties may be another tool to positively affect the fertility properties of composts, in addition to adjusting feedstock and process parameters.

Summary: The disposal of livestock wastes is an urgent task in China. Composting is a highly regarded method, and this study focuses on composting in a cold environment. The properties and bacterial community of the compost samples were investigated, and it was found that temperature plays a crucial role in the physical, chemical, and biological properties of compost. Specific bacteria were identified as biological indicators during the composting process. This research provides valuable information for composting in cold regions with low environmental temperatures.

Summary: The valorisation of vegetal waste as a source of crop nutrients is a circular strategy that improves the sustainability of horticultural production systems. This study evaluated the effects of organic amendments derived from vegetal residues on tomato yield and quality. The results showed that vermicompost, derived from previous tomato crop residues, had the highest yield and improved the nutritional quality of tomatoes.
