Soil analysing

Fine

In these days, I spent time for soil analysing. The result is going to be the base data, and according to it, the fertiliser is planed.

According to the text book, tomato needs 10kg of nitrogen per 1000㎡. 7kg of it is as base fertiliser, and the other 3kg is as additional fertiliser. And it needs also, calcium, magnesium and potassium as 7:2:1, and 50% of calcium and magnesium should be soluble.
For nitrogen of base fertiliser, I am thinking about bark compost.

It is fun, at the same time it is not easy to save the cost.
