In the present invention we disclose the method of manufacturing nano nitrogen, The resultant products “nano nitrogen is used as agrochemical (i.e. fertilizer, pesticide, herbicide, fungicide antimicrobial), but also for other applications, such as, pharma­ceutical, nutraceutical, catalyst development etc. The bottom up fabrication  approach allows the size and  other nanoscale properties controlled stable clusters using organic (oligo and polymer units) substrates. From the agrochemical perspective, nano nitrogen, nano zinc and nano copper can be applied to plants by foliar application, root drenching or by amending with soil.
