Soil analyze

It is the first time since last soil analyze in Oct 2011. It has been 6 months.
The result shows me my wasting fertilizers.
During each crops, I scatter the self made compost mainly to provide nitrogen and micro organics. But it seems that I did not have to. As almost elements are enough or too much in the soil including nitrate nitrogen which may occur the cancers.
And this too much nitrogen also can be the reason which occur the plant lice.
