If the method of concentrated application by ditching is used, fertilize, water and then ridge after ditching. The ridge height is about 25 cm, the bottom of the ditch is about 30 cm wide , and a ridge for walking is found between the large lines of 80 cm. The two ridges separated by 55 to 60 cm are covered with a mulch, and the mulch is placed about 10 cm on the outside of the two ridges .
