Description of the knowledge that will be created and how it will be disseminated to the community.

The knowledge to be created will provide a methodology to complement routine wet-chemical soil analyses with simplicity that will make possible to obtain key information (quantitatively and qualitatively) for applying soil fertilizer rationally in a way to meet the needs of sugar cane production. The technique based in multispectral remote sensing analysis, soil spectra analysis and multivariate models should be robust so that it can be applied in a wide region of Brazil that produce sugar cane. 

The dissemination to the community will be done in the usual academic way by publishing in international journals, participating in congress and conferences, but also through seminar and workshops with soil lab representatives, consultancy companies of soil fertilizer and sugar cane mill and producer's representatives.
