In agroecology it has been determined that fertilizers act as disease suppressors through biological mechanisms such as competition between beneficial and pathogenic microorganisms, parasitism and antibiosis.
▶ Organic fertilizers are used as a protective soil cover, which prevents surface runoff, regulates soil temperature and conserves humidity. As weed controllers, organic fertilizers can be used as mulch applied in an immature state.

≕ I invite you to stay tuned and read my next contribution ≔
A known issue is that organic fertilizers end up producing an effect that prevents seed germination due to a decrease in the passage of light and the presence of phytotoxic fatty acids for plants present in immature compost.
Frequently, the organic matter content in cultivated soils is not adequately replenished; therefore, the lowest organic matter contents are found in soils subjected to intense exploitation.
Organic fertilizers have the capacity to maintain or increase the levels of organic matter in the soil, improving its structure and therefore its water retention and aeration capacity, as well as the risk of erosion and compaction, a good part of its cation exchange capacity.
Basically this occurs because, by increasing the cation exchange capacity of the soil, more nutrients can be absorbed, thus reducing leaching losses), the color, which affects its heating capacity, the support of soil microflora and many of the functions, particularly water storage and infiltration capacity, nutrient supply and degradative capacity, are related to the soil organic matter content.

This is really good to know the beneficial effect of fertilizers and its contribution to health. Thanks for sharing
The article also specifies the effect of organic fertilizers in the natural control of weeds. Thank you for coming here.
