The quality of vermicompost from various sources composted with earthworm Perionyx excavates

Abstract

The quality of vermicompost depends on the source of earthworms feed such as animal waste (cows, buffaloes, chickens, and goats). The aim of the study was to obtain high quality vermicompost and to determine the parameters of vermicompost in accordance with the compost quality standard from SNI 19-7030-2004. The experimental design was Completely Randomized Design (CRD) with the treatment of types animal manures: consisted of cow, buffalo, chicken, and goat manures with 6 replications, so there were 24 experimental units. The results showed that the 9 parameters of vermicompost tested complied to the quality criteria of compost from SNI 19-7030-2004. The significant finding of this study was the weight of the remaining earthworms decreased from 12 g at initial weight to 2.42 g for cow dung, 2.38 g for buffalo dung, 1.62 g for chicken manure and 0,63 g for goat dung after harvesting the vermicompost. The highest quality of vermicompost according to the criteria of SNI 19-7030-2004 was cow dung, followed by buffalo dung, goat dung, and chicken manure. According statistical analysis showed that pH (H2O,1:5 w/v) is 8.90 (highest) for chicken manure, 8.60 (medium) for cow dung as well as 8.46 (medium) for goat dung, and 7.90 (low) for buffalo dung. Water content are not significant for all sources of vermicompost which is 50% more. Temperatures of vermicompost from goat dung (28.70°C) and chicken manure (28.29°C) are significant significantly higher than cow dung (27.68°C), and buffalo dung (27.89°C). Organic C content, total N content, and C/N ratio of vermicompost used descriptive analysis. Organic C content was highest in vermicompost derived from buffalo dung, followed by cow dung, chicken manure, and goat dung as well as total N content from goat dung, chicken manure, buffalo dung, and cow dung. Also C/N ratio from low to high are goat dung, chicken manure, cow dung, and buffalo dung.

Compost and vermicompost engineering for the growth of BISI 18 variety of maize on coastal Entisols

“…The chemical properties of Entisol, especially essential nutrients (P, K, Ca, and Mg), are classified as low to very low, with the soil acidity level slightly acidic. 1 with the chemical properties of soil from Kandang Mas village and other Bengkulu Coastal areas, it is almost the same, especially C-organic 3.34%, N-total 0.27%, P-Bray 1 6.6 ppm, K-dd 0.15 cmol(+)kg -1 , pH (H2O) 5.03 [10]. The quality of soil from the results of this research is low.…”

“…shows that the pH (H2O) and C-organic of vermicompost and compost have met the technical requirements for organic fertilizer with a pH of 4-8 and C-organic of at least 15% [9]. According to [10], vermicompost has an N-total of 1.41%, P-total of 0.77%, and Ktotal of 2.14%. The N, P, and K analyses of vermicompost (Table 3) are superior to those of [10] unless K is lower.…”

According to Isroi [11], compost has met the quality standards for compost fertilizer, namely pH (H2O) 6-7.49, C-organic 9.80-32%, N-total 0.40%, P 0.10%, K 0.20%, Ca 25.50% (maximum), and Mg 0.60% (maximum).…”

Problems associated with vermicomposting of dog excrement in practice using Eisenia andrei

“…Jamaludin et al (2012) vermicomposted goat manure with spent mushroom substrate (1:1) for 20 weeks, and their percentage of nitrogen that was comparable to our values was in the variant with 80% of goat manure (1.63–2.23% N); in the variant with 50% goat manure, their values were lower than ours. Riwandi et al (2022) vermicomposted cow dung, buffalo dung, chicken manure and goat dung in a tray for 60 days using Perionyx excavates . Their C:N ratio of vermicompost from cow dung was almost same as ours (11.9:1).…”

Comparative Study of Vermicomposting: Apple Pomace Alone and in Combination with Wheat Straw and Manure

“…According to Anandyawati et al [91], organoleptic properties, including texture, aroma, and color, are used to determine the level of maturity of vermicompost. Excellent vermicompost is considered to be odorless, dark in color (dark brown to black), with a loose and homogeneous texture, where the original components are no longer recognizable [92,93]. The dark coloration of vermicompost, according to López and Sainz [94], results from the absorption of heat during the decomposition process of organic materials.…”
