I'm interested in opinions and papers regarding these elements for plant nutrition and its relevancy today? Will be doing an article so please be prepared to go 'on record'. Thanks
Surendran in the context of application to plant nutrition. For example: we have always maintained a balanced NPK in fertiliser application, but now we seem to have commercial fertilisers with NPK with K applications higher than phosphorous. I know these are usually for flowering. But I have found application of these with these higher K ratios anecedotally provide better results. Also with respect to the problem with phosphorous shortages how will that affect plant nutrition. Also plant hormones are they an adjunct to nutrition (npk) or can they replace? Generally have we learned anything since we discovered NPK?
