I make delicious Sayama tea steamed for a long time at the Yokota farm.（Tea plantation management intertillage）

It was just what I improved to have sprayed substitute compost, but the inside plowed it last time.
 

I prevent the vaporization of the manure ingredient by mixing with the soil and am effective in enhancing the resolution.
In addition, deflection occurs because of rain after the fertilization when do not mix; a flow my late; may do it.
This is a plan of the last tea plantation management this year.
