Abstract
The soil is the fundamental bed of the plants, in its handling, the basic purpose is its conservation and it improves of its properties especially the physical ones; across the minimum tillage, to increase the yields in the cultivation. The cultivation of the vegetables is a basic source for the food securit y of the societ y; between them the car rot is much longed; needing between them of 25 to of depth in the soil preparation. Constituting the organic matter an important source in the nutrition of this cultivation. The study included three depths of vertical far ming (No Till, removal of the soil to 20 cm of depth and removal to 30 cm) with and without ear thwor m humus; distributed in a block at random. The results reflect that the yields of the fr uit, without difference between, have the following descending order: depth to 30 cm, depth to 20 cm and No Till. The organic matter not influence in the yield. The most economic and less aggressive No Till for the soil.
