Influence of conservation tillage on soil degradation prevention

Conventional practices of intensive agricultural production led to soil degradation which is reflected through the degradation of physical, chemical and biological properties of the soil. Conservation agriculture by its principles (crop rotation, permanent soil cover and conservation tillage) prevents soil degradation and / or mitigates the consequences of soil degradation as a conditionally non-renewable natural resource. The one of the most important aspects of conservation agriculture is conservation tillage with purpose to care environment, soil health and productivity and plant growth. Conservation tillage, in addition to preventing soil degradation, results in multiple positive changes in soil such as: prevention of erosion, loss of soil organic matter, improve soil structure, reduction of CO2 emissions into the atmosphere, conservation of soil water, reduction of temperature aberrations, increase of soil biodiversity, etc. Conservation tillage has special important role in prevention or well as in mitigation of climate change and its environmental degradation process (such as desertification). One of the main benefits of conservation tillage is the reduction of runoff that carries with it the remnants of agrochemicals and soil sediments. Conservation tillage reduces the exposure of non- mineralized organic substances to microbial processes, thus reducing the decomposition of soil organic carbon and CO2 emissions. By establishing and implementing a strategy for sustainable land management, food production will be more successfully harmonized with the growing world population while preserving natural resources from the process of degradation.
