There are different tillage methods in the world, including the zero tillage method, ie no plowing of the soil. For agricultural producers in Bulgaria it is said to be traditional producers or even conservative producers, for most of them they use the traditional practice of deep plowing as the basic tillage method. Although there are different theories available tested in practice, deep plowing is the most commonly used general tillage method. In Bulgaria, it is accepted as tested and considered as a tool that increases the fertility of the soil because other methods are not applied.
There is no universal recipe for basic tillage, tillage is done according to different soil types, predecessor and different ecological farming regions. Deep plowing is a prerequisite to increase soil fertility and provides high yield not only for plants planted in spring, but also for plants planted later. Pros and cons of the deep version - As with every application, the deep version has its pros and cons.
If we need to indicate the pros of this application, they are as follows:
- thanks to it, a deep release layer is created and the soil structure is improved;
- It is the most powerful method in combating weeds;
- ensures that autumn, winter and early spring rains remain more moisture in the soil;
- it is a major factor in increasing soil fertility;
- facilitates the introduction of organic and mineral fertilizers to the soil;
- It provides relief from many diseases and pests that occur in plants.
The downsides of the deep version are as follows:
- plow tracks are formed by working plows (compacted soil where roots are difficult to develop, water accumulates and other);
- By reversing the release layer, the microflora and microfauna that come above the soil surface are destroyed;
- the soil is subject to wind erosion due to the lack of plant residues;
- the soil holds water due to the plow track, and there are conditions for flooding and other.
