The land has to be tilled for 1 or 2 times before the seeds are broadcasted.

The above 20 seeds mentioned need to be mixed thoroughly and broadcasted by hand.

Just before flowering of the crops(in 3 months time), the crops need to be dealt in two different ways.

If the land is slushy, the entire crops need to be tilled again so that the crops as well as the soil are mixed throughly and allowed to decompose.

If the land is not slusy, the entire crops need to be cut at the base and allowed to decompose in the soil.

Mostly these needs to be done before the main crop is grown or if you are not growing any main crop and just for soil improvement, it is better to do this during the rainy season.
