Nell’interesse della produzione vegetale, l’analisi del suolo ha due scopi principali: stabilire l’idoneità e il potenziale produttivo di un terreno dedicato a un certo tipo di coltura vegetale e diagnosticare carenze intrinseche o acquisite o condizioni deleterie della copertura vegetale. Nella maggior parte dei casi, la valutazione della capacità produttiva di un terreno è ottenuta in modo soddisfacente attraverso la determinazione dei contenuti fisici e nutritivi del suolo. Negli ultimi tre decenni, i metodi per la determinazione dei nutrienti sono passati da procedure gravimetriche e volumetriche che richiedono molto tempo a tecniche strumentali più rapide e sensibili. Tuttavia, mancano metodi sensibili, selettivi e rapidi. Nella presente indagine, per la determinazione del boro dall’estratto del suolo, è stato utilizzato il metodo spettrofotometrico, basato sull’estrazione del boro con ferroina in cloroformio come complesso ferroina borodisalicilato, quindi il boro viene stimato mediante misurazioni fotometriche dirette dell’estratto colorato Non è stato possibile trovare alcuna relazione tra il boro disponibile e i parametri fisici, tranne che per i suoli del distretto di Pune che presentano una relazione definita tra il boro disponibile e il pH.
