We have researched the water lose in conventional, no-till with and without mulch layer in vegetation vessels and we have found that the upper layer in no-till without mulch layer system conducted to lose of much more water which results in poorer plant development. We have considered that the mulch layer prevents the water lose and improve the better root growing and plant developing. The conventional tillage as well as the minimum tillage helps creating an upper layer with larger pores which slow the water loses, too. Better results of minimal tillage can also be explained by better water keeping due to the loosened upper 5-7 cm of soil. Our conclusion is the need to manage the residue layer in order to reduce water loss which results in better root growth, plant development and better yield than conventional system in high evaporative climates.
