Not all soils are rich in nitrates. They can be applied as fertilisers, and be used as a soure of Nitrogen for plants.

maybe you can identify that the soil is lack of nitrate by looking on the root of the plant on that place... if the root is not healty it may lack of nitrate... but nitrate is one of compounds that can be found in soil and have effect on the plant...

I can think that healthiness of plants' roots is not just depending on nitrate quantity...

[baikuza]

yes. that why i said "..may.."

yes, and some of those plants such as legumes produce nitrate rich soil. Farmers allow fields to go fallow and plant it with nitrate rich plants and then turn it over the following season/s and plant crops or use as graze.

If you see a lot of clover growing that is a good sign.

side point: did you know lighting produce nitrates?

[baikuza]

ah, yes. that is pretty complex and hard to remember-just because it is 3 and half years ago-
haha... but it is a cycle.. it need N2 in air to make NH3...but i do not remember for sure it is NH3 or NH4... oh well, maybe NH3-hehe...
so if it happen naturally in an area which lack of lighting and N2... it is hard. and without Nitrosomonas or Nitrosococcus

thanks for all the help
i presume a compost heap may contain nitrate rich soils... right?

[baikuza]

yes, that is a good soil for plant to grow...
