Which practice can help mitigate soil acidification?

Applying lime is an established practice used to mitigate soil acidification. When soils become acidic, they can negatively affect plant growth by making essential nutrients less available and increasing the solubility of toxic metals. Lime, primarily composed of calcium carbonate, helps to neutralize soil acidity and raise the soil pH, thus improving nutrient availability and overall soil health. This process not only enhances the soil's fertility but also promotes a healthier environment for plant roots and beneficial soil organisms.

Using more acidic fertilizers would actually exacerbate the problem of soil acidification rather than mitigate it, while minimizing organic matter addition can reduce the beneficial effects that organic amendments have on soil structure and nutrient retention. Practicing crop rotation can be beneficial for sustainable agriculture but does not directly address the issue of soil acidity in the same way that lime application does.
