Question

2.What are the advantages of leveling?​

Answer 1

Answer:

improved crop establishment,

even water coverage of the field,

even crop stand and maturation,

reduction of weeds by up to 40 % (thereby a 75 % decrease of labour required for weeding),

increase of farming area by 5-7 %,

reduction of farm operation times by 10-15 %,

Answer 2

(1) to provide a slope which fits a water supply

(2) to level the field to its best condition with minimal earth movement and then vary the water supply for the field condition.

Because land levelling is expensive and large earth movements may leave significant areas of the field without fertile topsoil, this second philosophy is also generally the most economic approach.
