Soil is one of the first things you need to consider when choosing a gardening site. The best soil will be light and sandy, with little or no penetration by organic matter. But how do you know if the soil in your area is good? It may seem easy enough, but there are so many variables at play. Firstly, there will be plants in the vicinity that are healthier and may need less care.
Secondly, you need to determine if this is a location where you can consistently get quality shots of healthy plants. You may want to take a look at local news sources or even Google maps; some areas have been found to have unhealthy soil due to overuse or improper planting techniques.
Facts About Soil And Its Importance
Although the soil is the ecosystem’s backbone, it is the most overlooked environmental aspect. Like, how often do you mind soil’s quality the same way you do water?
Unknown to most individuals, the soil is the link between the air, living organisms like crops, and even water. Soil quality affects plants and vegetation growth.
For this reason, people should address it with great concern. Meaning, take care of the soil if you want to be food secure, have quality breathing air, and access clean water.
Why Is Soil Quality Important In Vegetation
Most stakeholders and farmers are oblivious of how much the quality of the soil affects productivity. Since soils and plants are co-dependents, you need to combat issues that question soil quality.
Read on to find out why land quality is vital in vegetation.
1. Provides Nutrients
Apart from that, healthy lands are home to organic matter. This matter impacts crops by enriching the soil with nutrients.
Therefore, when the soil is of high value, it boosts the plant’s value.
2. Acts As A Water Tank
Do you wonder how some vegetation is able to survive during an extreme drought? It is because high-quality soil can store water for plant use for a long time. This allows plants to have access to essential nutrients and water for a more extended period.
On the other hand, poor soils drain water faster and starve the plants when they need it most.
3. Helps In Root Anchorage
High-quality soils create stability for vegetation by anchoring their roots. But how does it involve quality? Well, valuable earth can withstand erosion, preventing exposure of roots in return.
Apart from that, rich earth has organic matter that is a good aggregator of soil particles. And with less porosity, the soil can support, and hold the vegetation firmly.
4. Temperature Regulation
Plants are like every other living organism. They also feel the impact of excessively hot or cold temperatures.
They, therefore, can wither and die. But then, plants can survive the temperature extremities if the land is healthy. The reason is, soil insulates the roots from drastic temperature fluctuations.
5. Healthy Soils Protect Plants From Climate Change
When humans release fossil fuels, the atmosphere absorbs excess carbon. In return, plants store more carbon than they should.
But the good thing is, after the oceans, the soil is the second-largest carbon store. For this reason, it drains the carbon from plants and the atmosphere, reducing the effects of global warming.
What Is Soil Fertilization?
When the humus in the earth decomposes and breaks down, it supplies the soil with nutrients that are useful to plants.
However, this process is not reliable on its own since it takes a long time. During which, plants may lack sufficient nutrients to promote growth. But then, you can fertilize the soil manually. Soil fertilization refers to supplementing of the earth with additional vital nutrients for superior yields.
You can replenish your land by using means such as recycling animal waste or applying artificial fertilizer.

Top 07 Key Challenges for Soil Quality
Unfortunately, vegetation growth and food production suffer even when you can boost the earth’s quality.
Here are some of the key challenges.
Although crop-growing is fun, overdoing it is harmful and causes irreversible damage to the land. For instance, when you grow the same crop on the same land for a long time, you tend to exhaust vital nutrients from the earth.
By doing so, the plants wilt and die. The only revival mechanism is to leave the land bare until it replenishes again.
2. Intensive Farming
When you continuously cultivate the land, you tend to strain the soil and weaken it. The fault in this practice is that it opens up to wind or soil erosion after the soil breaks. The erosion sweeps off crucial nutrients from the soil, leaving it bare and unhealthy.
Sadly, chemical fertilizers can cause more damage to the soil than you think. But how? Well, chemical fertilizers and other agrochemicals can mix and become toxic in the earth. The toxicity causes crops to underperform or die.
Apart from that, industrial waste dumping and landfill runoff can cause pollution and cause soil infertility.
Droughts and clay soils are the sources of soil compaction. And when the land dries out, it hardens and becomes dense such that it becomes incapable of taking in water.
The water at the top can cause salt build-ups and runs off that rob the soil of nutrients.
5. Soil PH
When you tamper with the soil’s chemical composition, you mess with everything that the earth can hold. Soil chemistry is a vital property that impacts the soil structures, and most importantly- the PH. And when you mess with soil PH, you automatically affect the land’s acidity levels.
Acidic elevations can increase the solubility of dangerous minerals like aluminum. Such reactions negatively influence the soil’s response to manure and fertilizers.
6. Moisture Content On The Land
Soil fertilization can be affected by the amount of soil water. The reason is, moisture serves as a solvent and transporter of the nutrients responsible for plant growth.
At ideal levels, moisture is also a nutrient itself. However, a lack of moisture in the soil prevents organic matter’s metabolism, reducing nutrient levels. Excess water, on the other hand, dissolves fertilizers and limits soil aeration.
7. Soil Texture
You can determine fertility levels in the soil depending on soil types and their structure. For instance, sandy soils are infertile because they can’t retain nutrients.
This makes regions with sandy soil infertile and unhealthy.
Soil And The Environment
It’s essential you check the quality of the soil before planting as it has a huge impact. Since soils don’t display obvious signs of stress, it’s up to you to check it up and feed it.
