Soil tillage is a fundamental agricultural practice that consists of mechanical manipulation of the soil to create a favorable environment for crop growth.This practice has been used for thousands of years and is still essential for Moderna agricultural production. We must clarify before continuing with the article, that this type of practice when applied excessively on floors, can cause some negative effects that will be mentioned later.

* Improve the soil structure: Tillage helps to break up clods and loosen the soil, which improves aeration, water infiltration and drainage. This is important for the development of plant roots and for the availability of water and nutrients. * Control weeds: Tillage can eliminate existing weeds and prevent their future growth. This reduces the competition for resources between weeds and crops and helps to improve yields. * Incorporate crop residues and organic matter: Tillage helps to incorporate crop residues and organic matter into the soil, which improves soil fertility and its water-holding capacity. * Control pests and diseases:Tillage can help control some soil pests and diseases by exposing them to natural predators and the air.

There are different types of tillage that can be used depending on the needs of the soil, the crop and the farmer, some of the most common types of tillage are conventional tillage that involves the complete investment of the soil through the use of plows or other implements, it is an effective method to control weeds and incorporate crop residues, but it can have a negative impact on the soil structure. Minimal tillage, this type of tillage involves soil alteration only in the root zone of the crop, it can be performed with a variety of implements, such as cultivators or discs, minimal tillage is less effective for weed control than conventional tillage, but it can have a positive impact on soil structure and erosion. There is also no tillage which consists of no soil disturbance, crop residues are left on the soil surface to act as a protective cover, no tillage is an effective method to improve soil structure, water quality and biodiversity, but it can be more difficult to control weeds.

The choice of the right type of tillage depends on a number of factors, such as the type of soil, the climate, the crop, the availability of machinery and the preferences of the farmer. It is important to carefully consider all these factors before choosing a tilling method. Tillage can have both a positive and negative environmental impact that we will mention below:

Positive impacts * Soil structure improvement: Tillage can help improve the soil structure, which can increase water infiltration, reduce erosion and improve water holding capacity. * Reduction of pesticide use: Tillage can help control some soil pests and diseases, which can reduce the need to use pesticides. Negative impacts * Soil erosion: Tillage can increase soil erosion, especially on sloping soils. * Soil carbon loss: Tillage can accelerate the decomposition of soil organic matter, which can lead to soil carbon loss. * Water quality degradation: Tillage can increase runoff and soil erosion, which can lead to water contamination with sediment and nutrients. |Final considerations| |------|

Dear readers, soil tillage is an essential agricultural practice that can have a significant impact on soil productivity, water quality and the environment. It is important to choose a tillage method that is suitable for the specific conditions of the site and that minimizes negative environmental impacts.
