Samadi ya nguruwe ni resource ikiwa inasimamiwa, na pollution ikiwa inaachwa bila mpango. Farm yenye pigs wengi inaweza kutoa manure na wastewater nyingi kila siku. Mpango wa taka unatakiwa kuwepo kabla herd haijakua.

Kukusanya na kutenganisha maji

Tenganisha storm water na manure water. Maji ya mvua kutoka roof yapelekwe sehemu safi, si kwenye manure pit. Hii hupunguza volume ya effluent inayotakiwa kusimamiwa.

Compost

Solid manure inaweza kuchanganywa na carbon material kama dry crop residues, sawdust au straw ili kutengeneza compost. Pile inayosimamiwa vizuri huwa na moisture ya wastani, oxygen na joto linalosaidia decomposition. Compost isiwekwe karibu na kisima au sehemu inayofurika.

Biogas

Farm yenye manure ya kutosha inaweza kutumia biodigester kuzalisha biogas na slurry. Uwekezaji unahitaji design kulingana na volume, water availability na matumizi ya gas. System ndogo sana kwa herd kubwa au kubwa sana kwa manure inayopatikana huleta matatizo ya economics.

Kutumia kama mbolea

Manure ina nitrogen, phosphorus na nutrients nyingine, lakini kiasi cha kutumia shambani kinategemea nutrient content, crop need, soil na area. Applying manure nyingi sana karibu na water sources inaweza kuchafua groundwater na surface water. Mature compost ni rahisi kusafirisha na kutumia kuliko raw wet manure.

Harufu na nzi

Harufu huongezeka kwenye anaerobic stagnant waste. Ondoa manure mara kwa mara, fix leaking drinkers, cover/handle storage vizuri na tumia composting inayosimamiwa. Nzi hudhibitiwa kwa kuvunja breeding sites: wet feed, manure piles za kudumu na carcass. Chemical fly control peke yake haitatatua mazingira machafu.

Dead stock na placenta

Hivi si manure ya kawaida. Vishughulikiwe kwa protocol ya farm na maelekezo ya veterinary/local authority. Katika disease outbreak, disposal method inaweza kubadilika kabisa; usihamishe material bila clearance.
