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 performed application of spring manure in a tea plantation, but performed intertillage after the fertilization the other day today.
This intertillage softens topsoil, and supply oxygen necessary for tea to the soil; and of the manure turn it over, and is crowded, and there is a purpose to plan prevention of to outer layer region of the Japanese radish distribution, prevention of weed.
