MNB Chart, page-9

I don't know if this had anything to do with today's increased volume and sp but there seems to be renewed interest in the fertiliser stocks after prices have recovered strongly from multi year lows and the fundamentals going forward look strong. This might just be coincidence because it doesn't mention MNB but higher phosphate prices are still not being factored in to the mc of MNB despite the recovery in the sp. From Livewire;

"The need to “feed-the-world” thematic was on full display this week when BHP finally got around to approving a $US5.7 billion stage 1 development of its Jansen potash project in Canada.BHP reckons its got a 100-year business in the making as potash demand grows in response to global population growth.The notion is that fertilisers like potash are needed in increasing amounts because crop yields have to rise to offset the pressure on food supplies from the dwindling availability of arable land, and because water is becoming a scare commodity.
While it was a 100-year decision by BHP, it was all that much easier to make now because fertiliser prices have been on the tear as the feed-the-world thematic takes shape.
