How parthenium compost sieving is done?

After removal of compost from pit we may find some stems which give impression that Parthenium plants have not so been decomposed yet. But actually, it is well decomposed. Spread that compost in the shady place to dry it. Coming in contact with air, soon wet of compost becomes dry and crumpled. Make a heap of this so dry compost. If still thick pieces of Parthenium stems are seen in the compost, beat them with the sticks. Sieve that compost with 2x2cm size mesh. For selling point of view, make packets of 1, 2, 3, 5 kg for kitchen garden and 25-50 kg for crops and horticulture.
