“…The possible reasons for resulted less amount of EC at the matured phase of composting could be the volatilization of ammonia and the precipitation of mineral salts [ 25 , 26 ]. For the improvement of agricultural soils, the acceptable level of EC in compost is < 4 dS/m [ 27 , 28 ]. Therefore, the prepared compost is good for improving agricultural soil fertility.…”

Lake Tana is the largest freshwater body in Ethiopia. Currently, the lake has been facing alarming environmental degradation and loss of biodiversity due to the invasion of water hyacinth. Although the weed is invasive, it can be converted into various benefits. Hence, this study was conducted in North Eastern Lake Tana, Sheha Gomengie Kebele. The main objective is compost preparation in terms of its drying periods, analyses, and user perception. Physicochemical and nutrient analyses were performed according to the standard procedures. Acid digestion was used for heavy metal analyses. From the result, the pH measurements ranged from 7.619 ± 0.195 to 7.719 ± 0.261, and the moisture content ranged from 38.712 ± 0.680 to 49.60 ± 9.06%. The mean electrical conductivity (EC) values of all treatments of matured compost ranged from 2.780 ± 0.542 to 3.51 ± 0.971 ds/m. The TN values of the matured compost ranged from 0.420 ± 0.379 to 0.754 ± 0.194 on a dry weight basis. The overall mean values of the C:N ratio for all the treatments were 11.60 which is within an acceptable range. A high amount of available P concentrations was observed in all compost treatments which ranged from 2.740 ± 0.190 to 2.940 ± 1.410 g/kg. Moreover, the concentrations of heavy metals in all treatments were below the permissible limit of different agencies and there was also no significant difference in the mean values of analysis of variance at (P < 0.05). Therefore, the prepared compost can be recommended for better agricultural purposes. Considering users’ understanding of compost preparation as an opportunity, converting WH into compost is promising in terms of its rich supply and the possibility of preparing in the dry season where labor is abundant. Therefore, it can be one way of sustainably reducing WH adverse effects on the Lakeshore.

“…The formation will lower the production of hydrogen. Several studies confirm that organic matter significantly reduces soil acidity (Muktamar et al 2018;Anggita et al 2018;Sianturi et al 2019;Muktamar et al 2016). The study aims to determine the acidity reduction of Pb and Cd contaminated soil under the vermicompost application.…”

Contamination of heavy metals on the soil leads to an increase in its acidity. Vermicompost application is commonly used to improve the properties of soil. The study was carried out to determine the reduction of the acidity in Pb and Cd contaminated soils under the application of vermicompost. Two laboratory experiments were set using Completely Randomized Design (CRD) with two factors. The first factor was soil samples, vis Inceptisols, and Entisols, and the second factor was the rates of vermicompost, consisted of 0, 5, 10, 15 g kg-1. The treatment combination was repeated three times. The soils were pretreated with 10 mg kg-1 Pb or Cd using Pb(NO3)2 and Cd(NO3)2. Three hundred kg soil sample was incorporated with vermicompost and placed in a 500 ml plastic bottle. The mixtures were incubated for eight weeks, and the moisture of the soil was maintained at field capacity. The acidity and soil temperature were monitored every week. The study indicated that Pb contaminated soil acidity increased to the sixth week of the incubation and decreased afterward. However, the acidity of Cd contaminated soil was consistently increased during the incubation. Treatment of vermicompost significantly lowered the acidity of both Pb and Cd contaminated soils. Contaminated Entisols had a higher response to the application of vermicompost than that of Inceptisols. This finding is significant in assessing acidity risk and possible management intervention for Pb and Cd contaminated soils.

“…Hasil penelitian Simatupang et al (2002) menunjukkan, pemberian kompos gulma meningkatkan hasil sejalan dengan meningkatnya dosis kompos gulma yang diberikan. Di samping itu, penggunaan pupuk organik juga dapat memperbaiki kualitas tanah (Muktamar et al, 2016 b ) serta dapat mengurangi penggunaan pupuk sintetik (Setyowati et al, 2015;Simarmata et al, 2016). Penelitian ini bertujuan untuk menjelaskan pengaruh pupuk sintetik, kompos rumput maupun kombinasi keduanya terhadap pertumbuhan dan hasil tanaman tomat.…”

[EFFECT OF WEED COMPOST AND SYNTHETIC FERTILIZER DOSAGE ON TOMATO GROWTH AND YIELD (Lycopersicum esculentum Mill.)]. The growth and yield of tomato plants are influenced by fertilizer and nutrient content in the soil. This study aims to investigate the effect of a combination of synthetic fertilizer and weed compost on the growth and yield of tomato plants. The study was conducted in November 2016 through June 2017 in Agronomy, Faculty of Agriculture, University of Bengkulu, at an altitude of ± 10 m above sea level using a Completely Randomized Design (CRD). The treatments consisted of synthetic fertilizer at a rate of 180 kg/ha N, 150 kg/ha P2O5 and 100 kg/ha K2O (control), grass compost 30 , 40 and 50 tons/ha, 50% control + grass compost 15 tons/ha, 50% control + 20 tons/ha grass compost and 50% control + 25 tons/ha grass compost. The results revealed that the vegetative growth of tomato plants fertilized with grass compost 30 tons/ha and a combination of grass compost + 50% control did not differ from control treatment. Tomato yield fertilized with grass compost 30 tons/ha and a combination of 50% control + 15 tons/ha grass compost was higher than the control treatment. Therefore, 15 tons/ha of grass compost can reduce the dose of synthetic fertilizer by 50%.
