Not sure - I'm strong on Chinese stats, but in Australia, my knowledge is limited to individual farms. But it's worth noting that from about 2000 to 2006, there was a really bad drought in the wheat-growing belt of North-West New South Wales and South-West Queensland. A lot of farmers gave up on their crops, and that would have hit fertiliser use.

Earthquakes and (volcanoes) have such large human impacts that people are devoting massive efforts and computers to understand them better. Here's one example TUM - TU München: Computational record on SuperMUC One might infer from such effort that it is not at all easy to figure these things out. This does not exclude the possibility that some people believe that it is easy.
That prediction table seems to have nearly full coverage, with items for 20 out of April's 30 days. On an earthquake site, I'm seeing a lot more more quakes listed. Here is a list, sorted for just the events of 5.5 and higher (the cutoff on the above prediction table), and dated by UTC, not local time: April 1, 8.2, Chile (plus weeks of huge aftershocks) April 2, 6.0, Panama April 2, 5.6, Japan April 3, 5.6, Sumatra April 4, 6.0, Solomon Islands April 4, 5.5, Greece April 10, 6.1, Nicaragua April 10, 5.6, Tonga April 11, 7.1, Solomon Islands April 12, 7.6, Solomon Islands (plus days of huge aftershocks) April 15, 6.9, Bouvet Islands April 17, 6.2, Balleny Islands April 17, 5.5, Celebes Sea April 18, 7.2, Mexico April 18, 6.0, Santa Cruz Islands April 18, 5.5, Alaska April 19, 7.5, Solomon Islands (plus a couple large aftershocks) Have you scored the 'predictions' against the null hypothesis?
Ive watched these monthly predictions for a year or two. I dont believe Ive ever seen a month with so many high "R4-R5" periods predictions. Nor have I seen the resulting corresponding coronal holes, coronal mass ejections and flares. Nor have I seen a month of so many greater than magnitude 6 quakes. I have witnessed many R5 periods which have spawned tropical storms as well. Also volcanic eruptions are triggered during these high periods as well. But my observations are casual.
Catalogs of coronal mass ejections are available online, for example here: The SOHO/LASCO Instrument Homepage Which should make it feasible to look for correlations with earthquakes or other terrestrial events. Or simply to up one's game from the level of 'I never saw this many'. Does this web article answer the question well enough? Do solar flares cause earthquakes? :: The Sun Today cause the scientific study I linked to earlier in the thread did not seem to settle the matter.
Humans have an incredibly powerful ability to 'see' patterns in white Gaussian noise. That is why I put little stock in casual observations of this sort. Show me some computed correlations over long time periods.
Pattern recognition is totally a survival skill. It persists in other ways that are not necessarily adaptive. Pareidolia - Wikipedia, the free encyclopedia But, entertaining as all get-out.
