Cocoa Saplings and Ammonia Sulfate

I've been regularly supplementing the soil on my plots with NPK, but I'm also giving my cocoa saplings a good growth spurt through the application of ammonia sulfate.

This seedling was given a half matchbox of ammonia sulfate and photographed for the first time on 5/3/2012 (Figure 1) and the second picture was taken on 5/12/2012 (Figure 2). Note that two different cameras were used, and that explains the color difference:

This seedling was given a full matchbox of ammonia sulfate for the first time on 5/3/2012 (Figure 3) and the second picture was taken on 5/12/2012 (Figure 4):

If you compare the two, it is quite easy to see that the full matchbox of ammonia sulfate has a far more substantial impact than the half matchbox. This experiment was necessary, though, because ammonia sulfate can kill saplings if it is not given in the correct amounts. From here on out, its matchboxes all the way down!
