How to prepared Organic Fertilizers, Farm Yard manure, Vermicomposting,
Poultry manure, Oil cake
Farm Yard Manure:
Dung
obtained from domestic animals like cows, buffaloes, sheep, goats horse and
other animals along with urine, bedding material, crop residues are collected
daily and placed in trench or pit.
The
size of pit should be 6-7m x 1.5-2 m x 1m. The pit should be provided with a
shed to protect the manure from rain and hot sun especially in summer and moon
soon season. The manure materials should be added to the pit until the height
of the added material is 40-50 cm from the ground. Then the upper portion of
the stack should be coated with mixture of mud and cattle dung.
Heap Method:
Collected
material placed in heap in high land until the height of heap reached about 1m
above to the ground level. The FYM will be ready in 3-6 month.
Vermicomposting:
Collect
the biodegradable waste including vegetable waste, crop residues, weeds, agro
industry waste, dry leaves of crops, sugarcane trash, animal manure, dairy and
poultry waste. Digest the material same heap method as like FYM. Select a cool
and moist place. The predigested organic material along with animal dung place
in the container (tank, earthen bowl), then suitable species of earthworms (more
than 2000 species in the world, Eisenia fetida, Eisenia Andrei,Lumbricus
rubellus) released in the container. The container should be covered with thick
cloth and jute bag to maintain a dark environment. After collection the compost
should be sieved to separate fully compost material. The partially compost
material earth worms, their eggs or coccon should be placed again in the
container future compost preparation.
Poultry manure:
Collect
the fresh poultry manure for pile composting. To avoid the nutrient loss cover
with the plastic sheet. Due to low C: N add rice husk or straw. It will be
prepared in 8-10 weeks.
Anaerobic condition:
Fresh
poultry manure with rice husk is placed in the pit, sufficient water is added
to maintain moisture, the pit is covered with mud plaster.
Crop residue:
Agriculture
crop residues, leaves, stem and roots directly plowed in the land.
Oil cake:
Oil
cakes are byproducts of oilseed crops ( mustard, sesame, linseed) after the oil
has been extracted from oilseed. Oil seed cake provide easy quickely nutrient
release.
