How rice straw decompose quickly.?

Question

we have lot of affulent water(enriched high nitrogen) after extracting dextrose from maize grain .Can we use this affulent water to decompose the paddy straw and manufacturing organic manure. suggest the methods.

Answer 1

The keys to good compost making are adequate N

supply and moisture content and abundant microorganisms.

    Composting is best when sites are level, well

drained and under shade, and when compost materials are chopped into small pieces (3-5 cm).

    Compost heaps should be kept moist — not too wet

(e.g., no water draining from the compost pile) and

not too dry (e.g., straw so dry it cracks when bent)

    To aid decomposition, sprinkle your compost heap

with decaying material (e.g. cow dung in a slurry with your N rich affluent water).

Such additives are desirable because they contain

nitrogen and microorganisms that aid decomposition.

     It is best to mix and turn the heaps every two weeks.

     When moisture and temperature conditions are

good, compost will be ready in 4-8 weeks.

     Rice straw is fairly rich in potassium but very low in phosphorus,  Any thing that you might have that would add some organic phosphorus would improve your final fertilizer.

     I think you have natural freely available compounds here that can be made into a valuable fertilizer.  Not to mention removing potentially harmful by products from the environment.

I think you have a winning idea here.   Best of luck.

Answer 2

I'am actually doing a study on the decomposition of stubble by adding fertilizer for no-till crops. Both the fertilizers we have used are high in nitrogen. The study isn't completed yet but so far we have seen an increase in the deposition rate. The high nitrogen makes a great environment for microorganisms which break down the stubble, but in this study I can already see a problem. The problem is that even though its a great environment for good microorganisms its also good for pathogenic organisms. We have been monitoring the fungi growing on the stubble and have counted quite a few fusarium wilt species. Now I'm just a student studying agriculture so I dont know if this high count of fusarium is going to be a problem or perhaps there is a way you can kill all the bad organisms.

Anyway adding the affulent water to the straw should help in decomposition.
