Abstract High population growth in developing countries also increases the amount of waste. Indonesia produces large household solid waste production, namely 2.5 kg per day. Vermicompost is best alternatives, cheapest and does not harm environment. In this study, vermicompost method was used, worm weight ratio affected N, P, K content fertilizer. The results sample test, time variable, highest ...

Green fluorescent protein-labeled Escherichia coli O157:H7 and Salmonella enterica serovar Enteritidis were inoculated at 10(7) CFU/g into cow, hog, or chicken manure. Ten- or 11-day-old soldier fly larvae (Hermetia illucens L.) (7 to 10 g) were added to the manure and held at 23, 27, or 32 degrees C for 3 to 6 days. Soldier fly larvae accelerated inactivation of E. coli O157:H7 in chicken manu...

Methane emission f rom l ivestock and agricultural wastes contribute globally more than 3 0 % to the anthropogenic atmospheric methane source. Estimates of this number have been derived f rom respiration chamber experiments. W e determined methane emission rates f rom a tracer experiment in a modern cow shed hosting 43 dairy cows in their accustomed environment. During a 24-hour period the conc...

the effects of poultry manure and cow dung in comparison with the nematicide, carbofuran on the yield of okra infested with root-knot nematode meloidogyne incognita race 2 were investigated. two plots of 17×11 m, each naturally infested with the mentioned nematode, were selected for the study. treatments were poultry manure and cow dung each at the rates of 5 and 10 t ha-1, carbofuran 3g at the...

The efforts were made to study the impact of vermicomposted and composted farmyard manure (FYM) along with some combination of NPK fertilizers, on field crop of garlic (Allium stivum L.). A total of six experimental plots were prepared: T1 (recommended doze of NPK), T2 (vermicompost @ 15t/ha), T3 (20 t/ha vermicompost), T4 (15t/ha vermicompost + 50 % NPK), T5 (15t/ha farmyard manure), and T6 (f...

Field experiment was conducted during 2003-04 to study the effect of vermicompost, farmyard manure and water hyacinth compost in comparison to chemically fertilized and unfertilized plots on crop-plants in HYV Swarna and local variety Magaisal. The experiment followed split plot design with two varieties of rice in the main plots and fi ve nutrient sources randomized in sub plots. Signifi cant ...

Background and Purpose: The Phytoremediation efficiency of heavy metals is one of the important points in environmental studies. This research was conducted to investigate the effect of cow manure, elemental sulfur, and EDTA on Cd uptake by Indian mustard in a Cd-polluted soil in the presence of Thiobacillus thiooxidans. Materials and Methods: Treatments consisted of applying cow manure (0, 5,...

This study aimed to investigate the effects of tow nanoparticles (NPs) on the absorption, accumulation, reproduction of the Eisenia fetida. A 4×2×2 factorial experiment in a randomized complete block design with three replications was conducted. The factors included in the experiment are the content of NPs at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of NPs at two le...
