Trawling through the TNAU website (Green Manure section) (http://agritech.tnau.ac.in/agriculture/agri_majorareas_greenmanure.html), I have come across a rather handy application that can help you shortlist the recommended green manure or green leaf crops based on your site (farm). this tool takes into consideration your location, purpose etc and provides you a list of entities (plants) that would be an ideal choice. looks very useful this

[font=courier] Good source of info, thanks. However did not see anything on the disadvantages, or precautions to be taken during green manuring. Did I miss it? Will check again.[/font]
like in all cases anything done without planning and due consideration of long/short term impact / returns can turn into a disaster, holistically green manuring seems to have a lot of positives over negatives but best to look at them beyond just the NPK mentality
i feel (pardon my ignorance on this subject) that any green cover that is allowed to spread without any management will eventually turn into a problem sooner or later though forests challenge this theory however forests have their natural ecology doing all the maintanence for them which may not be available in a farm or plain land
[font=courier]Have absolutely no doubts at all about the effectiveness of green manuring. It’s highly recommended, and it’s impossible to carry out natural farming without adopting this practice, at least in small bits . Please don’t feel I am questioning it, not one bit, in fact I am staunch advocate of this method, though not in the textbook fashion mentioned in the link. What I am trying to say is that there could be certain pitfalls for someone new to the practice, and they never get over the initial reversal to try it out again.This occurs only when the method is not implemented judiciously.
But definitely yes, the positives greatly outweigh the negatives,there’s more to gain and not so much to lose. [/font]
No need to look for seeds of green manures. Cow dung of a grazing native cow does the trick. They normally feed on a variety of grasses and greens, often taking in the seeds. Once Jeevamrutham or Amruta Pani is prepared using the dung and applied to the soil a variety of green cover starts covering the soil . When these greens grow way to tall and interfere with the operations, they can be slashed down
I just replied to your mails with the intention of trying to help a farmer or his query. Too bad that you chose to put the matter on the board without asking me. Whatever was conveyed as private message is being posted on the board without my knowledge…Ask your conscience if this is fair, if you have any that is.
If you let the Cow graze in natural surroundings it will choose what is required. It grazes on different types of grasses and weeds , and the diverse types of grass and weeds appear for a reason,balancing the soil. Hence for green manure these plants germinating from Cow Dung are sufficient. If you are specifically looking at nitrogen replenishment go for glyrecidia or legumes. But cover the whole area using only legumes, slash them down and cover the soil may be impractical as well as ineffective.
