The period following the harvest is often seen as a phase of rapid transition. Yet it is a crucial time for soil dynamics. Even before cover crops are established, the soil enters a decisive phase: that of biological and structural recovery<\/strong>.<\/p>

During this short window, numerous processes take place: the breakdown of plant residues, the reactivation of microbial activity, and the natural restructuring of soil layers and porosity. When managed correctly, this period directly influences the quality of subsequent crops, the availability of nutrients, and the soil\u2019s ability to withstand climatic fluctuations.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

1. Why does soil activity slow down after harvest?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

A teaspoon of healthy soil can contain more living organisms than there are people on Earth<\/strong>! It is sometimes assumed that soil biological activity will naturally resume as soon as the harvest is over. In reality, this depends heavily on the physical and biological conditions of the field. Living organisms: bacteria, fungi, earthworms and other macrofauna, need a favourable environment to carry out their functions of decomposition, mineralisation and soil structuring.<\/p>

Three factors play a major role: air circulation, water availability and the presence of readily degradable organic matter. Crop residues left after harvest constitute a significant source of carbon, but their utilisation depends directly on soil life.<\/p>

When the soil is compacted or poorly structured, these processes are restricted, which can occur after harvesting due to the passage of heavy machinery. The decomposition of residues then slows down, as soil life is stunted. This situation can lead to an accumulation of poorly degraded residues on the surface, a reduction in soil biodiversity and a decrease in the availability of nutrients for subsequent crops.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

2. Soil decompaction after harvest: is subsoiling necessary?<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

According to various agronomic sources, soil compaction can reduce root penetration and lead to yield losses of between 5% and 30%,<\/strong> depending on the crop, the degree of compaction and climatic conditions.<\/p>

Before establishing cover crops, certain mechanical operations can help restore the soil\u2019s physical properties. The aim is not to increase the number of passes or to work the entire soil profile deeply, but to target compacted areas in order to reactivate the soil\u2019s natural vertical structure and facilitate the establishment of the cover crop<\/strong>.<\/p>

Unlike ploughing, the use of a cracker<\/a><\/strong> minimises disruption to biological activity as the soil layers remain in place. It also allows plant residues to remain on the surface (no deep incorporation).<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

However, this operation must be carried out judiciously and preceded by an assessment<\/strong> <\/a>to verify the actual presence of compacted areas and to adjust the working depth accordingly.<\/p>
