The soil, a great wealth

Today we are going to talk about the different organic sources present in the soil. This is an article that was published on the site "Sciencing" on July 21, 2017. 

An organic matter consists of decomposing plant and animal matter I knew that microbes from various sources. It is widely used by gardeners because it promotes rapid plant growth and improves soil structure and minimizes soil erosion by moisture-retaining winds. 


The first kind of organic matter can be characterized as animal manure, which is the excrement left in a pile. It contains nitrogen, phosphorus and sulfur. 


We can also find this phenomenon when mowing the lawn which can provide up to 25% of the total fertilizer needs of a lawn.


Vegetable peelings (potatoes, carrots, cabbage...) can be released in the form of a compost heap which favors the appearance of fungi, bacteria and earthworms which allow the appearance of nutrients. It is a process of decomposition.


Cardboard or straw can also play this role. Indeed, they can improve the structure of the soil during the decomposition process despite the fact that they do not produce nutrients.

On Shaky Ground

By: Hannah Meadows The New Madrid fault line is a growing danger right under peoples feet. Most people don’t realize how catastrophic it would be if the fault line went off and the worst part… there is no telling when it will go off. Usually, earthquakes wouldn’t be an issue in places like California because all of their buildings are built to withstand earthquakes. However, the New Madrid fault line sits right along southern Missouri and Missouri is known for its sedimentary rock. This means an earthquake in Missouri would cause all buildings and houses to be buried since they aren’t built to withstand earthquakes. Now what would the statistics really look like if the New Madrid fault line were to go off unexpectedly?  84,000 buildings damaged and 37,000 more destroyed, almost entirely residences  Over 15,000 people killed and an additional 120,000 displaced Nearly 200 schools and over 100 fire stations would be damaged  37 hospitals and 67 police stations would be compl...

Energy: Hydropower Pros and Cons

Image
 Hydropower is not often talked about as a primary option for sustainable energy, however, 6.6% of energy produced in the U.S. is through hydropower, compared to solar energy which happens to only be 2.3% and is usually the first thought when someone mentions “clean energy.” The reason for this being the majority hydropower plants only give energy to large-scale, industrial operations.  Hydropower boasts a few positives that make it a viable option, those being that it is reliable, safe, and produces a very low amount of emissions. Other than that, they are fairly expensive to build, and they have a very realistic potential to cause droughts. Hydropower is an interesting source of energy and as of now it is only really used for industrial use, however in the future there is a very real possibility for it to be used to power residential areas.  https://www.solarreviews.com/blog/hydroelectric-energy-pros-and-cons#pros-and-cons

They called it a shrinking world because our technology is getting even better and better. Anyways going into the article there is a graph and a description of the burgeoning population of the globe. After it talk about this problem it gets into how this can help our food problem and how we are on our way to a new type of farming. It ends off with them giving numbers on there work with BI intelligence and how much money they made in 2020 and what they are projected to make in 2050.
