Vermifilters are enclosed reactors made from durable materials that eliminate the entry of vermin, usually plastic or concrete. Ventilation must be sufficient to ensure an aerobic environment for the worms and microorganisms, while also inhibiting entry of unwanted flies. Temperature within the reactor needs to be maintained within a range ...
In agriculture, chloropicrin is injected into soil prior to planting a crop to fumigate soil. Chloropicrin affects a broad spectrum of fungi, microbes and insects. [12] It is commonly used as a stand-alone treatment or in combination / co-formulation with methyl bromide and 1,3-dichloropropene.
Vermicomposting uses worms to decompose waste and make nutrient-rich "worm manure". Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast.
Biosolids composting plant biofilter mound - note sprinkler visible front right to maintain proper moisture level for optimum functioning. Biofiltration is a pollution control technique using a bioreactor containing living material to capture and biologically degrade pollutants.
Pesticides can eliminate some animals' essential food sources, causing the animals to relocate, change their diet or starve. Residues can travel up the food chain; for example, birds can be harmed when they eat insects and worms that have consumed pesticides. [50] Earthworms digest organic matter and increase nutrient content in the top layer ...
Soil steaming is an efficient method to kill nematodes before planting a crop, but indiscriminately eliminates both harmful and beneficial soil fauna. The golden nematode Globodera rostochiensis is a particularly harmful pest that has resulted in quarantines and crop failures worldwide. It can be controlled, however.
Fumigation is a method of pest control or the removal of harmful microorganisms by completely filling an area with gaseous pesticides, or fumigants, to suffocate or poison the pests within. It is used to control pests in buildings (structural fumigation), soil, grain, and produce.
Aside from EPNs, the soil ecosystem includes predatory, bacteriovorous, fungivorous and plant parasitic nematode species. Since EPNs are applied in agricultural systems at a rate of 1,000,000 inhabitants per acre (2,500,000/ha), the potential for unintended consequences on the soil ecosystem appears large. EPNs have not had an adverse effect on ...
