What makes the soil fertile? What makes the soil fertile?
The fertility of soils is given by the amount of nutrients of them, that is, the substances required and necessary for plants to develop well.
Consequently, we can say that a soil is fertile if:
• Its consistency and depth allow good root development and fixation.
• It has the nutrients that vegetation or cultivation requires.
• It has the ability to absorb and retain water, keeping it available for plants to use.
• It is sufficiently airy.
• It does not have toxic substances.
Soils support the planet's biodiversity, housing a quarter of it, as well as helping to combat and adapt to climate change, due to its effective role in the carbon cycle. Soil is therefore a non-renewable resource, as its degradation is greater than its capacity for renewal, and its conservation is necessary for food security and a sustainable future
When the soils are covered with vegetation, they retain their fertility. A good example is the forest: the roots of trees hold the earth, the foliage of the tops softens the impact of rain and the force of the wind. Dried leaves that fall (litter), along with dead animals and their droppings, decompose thanks to microorganisms, which are there to feed on them, thus forming humus. Said material is a type of organic fertilizer that fertilizes the soil, thereby increasing surface porosity, which will allow it to absorb water slowly making it more available. The same thing happens with forests, but let's consider that when these trees are cut down, that balance disappears and as a result microorganisms die, soils are damaged, and therefore the ecosystem is affected, bringing harmful consequences to the planet, as it is happening, with the lung of the amazon and as happened with the african rainforest.
In my personal experience, as an agronomist and teacher of the area, even though soils A1 and A2 are very fertile soils, you can particularly make a soil even in the middle of a very arid area, fertile, if you use alternatives to improve them, such as the use of compost, foliar fertilizers based on vegetable debris, retention uses of water (torobas) and others; or in their effects, seek to adapt crops to those areas, then productively you can consider those soils as fertile.
As the saying goes it depends on the crystal you see it with.
