Engineering soil is when ground is prepared(engineered) for an specific purpose. Soil is dirty or ground naturally found on earth.
By Oscar Venegas "Ozkhar"
Plants can grow in rocks under certain conditions. Some plants have adapted to grow in rocky environments, such as cliffs, rocky slopes, or crevices. These plants are often referred to as "rock plants" or "rock garden plants." They have specialized adaptations that allow them to thrive in the challenging conditions of rocky environments.
These adaptations include:
Small size: Many rock plants are low-growing and have a compact growth habit, allowing them to fit into crevices and gaps in the rocks.
Drought tolerance:
Rocks can absorb and retain heat, causing the surrounding soil to become dry quickly.
Rock plants often have adaptations to conserve water, such as succulent leaves or deep root systems that can access water trapped within the rocks.
Anchoring mechanisms:
Some plants have specialized root systems that can penetrate and anchor themselves to the rocks, enabling them to withstand strong winds and erosion.
Nutrient acquisition: Rocks generally do not provide much organic matter or nutrients for plants. However, some rock plants have adaptations to obtain nutrients from other sources, such as through symbiotic relationships with fungi or by trapping and decomposing organic matter that accumulates in rock crevices.
Soil erosion is found in North America, South America, Europe, Africa, Asia, Australia, New Zealand and some other places. But these are the basic places for soil erosion to be found in.
Trees affect the soil in a good way. They are an important part of erosion control. Tree roots bind the soil, while their leaves break the force of wind and rain on soil. They reduce water runoff and sediment deposit after storms, and conserve rainwater.
This line suggests a desolate, barren landscape where the ground is exposed and devoid of any covering. It implies a sense of vulnerability and detachment, indicating a loss of connection or sensation between the feet and the earth beneath them. The imagery conveys a stark and isolating environment.
You can find essays about different subjects in academic journals, essay collections, online databases, or websites devoted to essays such as "The Paris Review" or "The New Yorker." Many universities also have digital repositories where you can access essays written by scholars and students.
Soil is vital for everyday life:
Food production: Provides nutrients for crops.
Water filtration: Purifies water as it percolates.
Supporting ecosystems: Offers habitat for plants and animals.
Carbon sequestration: Stores carbon, mitigating climate change.
Building material: Used in construction.
Recreation and aesthetics: Supports outdoor activities and enhances landscapes.
Medicinal resources: Source of pharmaceuticals and traditional medicines.
Acidic Soil ( pH is low) may be treated with lime, or crushed limestone.
Both these substances rect with the aciudic ions in soil to form a salt, water and carbon dioxide. #
Thereby increasing the pH to about '7'
If you see a farmer putting a white powder on fields, he is liming the field in order to increase the pH from acidic to a more neutral pH.
Here is the chemical eqution.
2H^(+) + CaCO3 = Ca^(2+) + H2O(l) + CO2(g).
NB They do NOT use an alkali, because in may produce an excess of alkali pH > 7.
Leaving aside the obvious (wet soil looks darker), the amount of organic matter or humus in a soil controls how dark the soil is. Generally the darker a soil is, the "richer" it is considered to be.
Evaporation.
There are two common ways in which soil is often wasted.
First, improper farming practices such as over-tilling or excessive use of chemical fertilizers can lead to erosion and soil degradation.
This not only reduces the overall quality of soil but also harms its ability to support healthy plant growth.
Secondly, urbanization and industrial development often result in the removal of topsoil during construction activities.
Topsoil is the nutrient-rich upper layer of soil, and its removal can seriously deplete vital resources necessary for agricultural purposes.
It's important to address these issues to prevent the waste of soil. Implementing sustainable farming practices, such as crop rotation and organic farming, can help preserve soil fertility and prevent erosion.
Additionally, during construction projects, measures can be taken to protect and preserve topsoil, including using erosion control techniques and proper soil management.
By being mindful of our farming and development practices, we can contribute towards the conservation and sustainable use of soil for future generations.
Soil typically doesn't float in water; instead, it tends to sink. The buoyancy of an object in water is influenced by its density. If soil particles are denser than water, they will sink. However, if there are pockets of air or organic matter in the soil, they might trap enough air to make the soil appear buoyant temporarily.
Neutral or slightly alkaline conditions.
Bajra does not tolerate acidic ( low pH) conditions.
Am writing this for the sake of people who have yet to be a victim of a scam. I invested all my funds hoping to gain more profit after 90 days but to cut the story short, it was a scam platform I was investing on without knowing. There are a lot of platforms you have to be careful about these fake online platform. Forward, I was able to recover the funds back with the help of Saclux Comptech Specaialst who was recommended by a lawyer who has a similar issue. There are still legit agents out there and am recommending sacluxcomptechspecialst AT engineer DOT com
I will always be grateful to this great hacker, Saclux Comptech Specialst. Although losing your funds can be quite distressing, there is a way to recover from it when you have a legitimate agent.

However, green plant life growing out of the soil does.
A green leaf plant takes in carbon dioxide. Under the process of photosynthesis ( uv/sun light is needed), the plant breaks down the carbon dioxide, into its component elements.
The carbon component remains in the plant as biomass. The oxygen component is released back intoi the atmosphere. This maintains the oxygen level in the atmosphere, at about 20%.
It is a natural process that humans neither hear, see nor smell, so short of scientific invesigation we cannot tell how fast it procedes. However, it must go on at a fast rate in order to remove CO2 from the atmosphere and replace it with oxygen.
In chemistry/biochemistry/geochemistry ,there are three cycles going on all the time. they are the nitrogen cycle, oxygen cycle and carbon cycle. I'll leave you to investigate these cycles.
Trading is a good thing. i lost a lot before I got to where I am today. if you need assistance on how to trade and recover the money you have lost from scam broker email (Wizesafetyrecovery) to get his new amazing strategy, If you
are having problems withdrawing your fund from your trading broker even when you were given a bonus, just contact him, he has worked with a trading broker for 6years, he has helped a lot of people. contact him

The soil must be well-draining, neutral to slightly acidic, fertile, and dry or sandy
Size up the area you want loosened, start in a forward spot, Jab in a pitchfork, step on it to sink it, twist it back & forth (1-2, 1-2, 1-2), pull the handle about halfway down toward you, remove pitchfork, step back one step, jab in pitchfork, repeat as above until entire area you sized up (or a desired portion) is done to your liking.
Put down the pitchfork, take a break, go get a tasty iced tea. It's all about the tea. We do it for the tea. Enjoy the tea, and rest assured that now the seed you plant will be better able to germinate, and let their little roots sink in for better nutrient extraction.
