Donkey as soil manager
Donkeys love to roll around extensively. With this habit, the animals can protect the soil and enable plants to grow better. Author: ZDF/TerraX/Luisa Zech, Lara Franke/Tobias Lenz/Sebastian Kerz/ MUSIC NN Translation and dubbing: alugha Click here to see more videos: https://alugha.com/TerraX
CO2 Storage in the Plant and Soil System
For more Science Videos: https://lt.org/ * The accumulation of carbon dioxide (CO2) in the Earth’s atmosphere is responsible for one of the most pressing problems of our age, global warming. In this video, SUSAN TRUMBORE analyses the key role that plant and soil systems play in the carbon cycle in o
The Nitrogen Cycle | Environmental Chemistry | Chemistry | FuseSchool
Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is continually cycled through the air, soil and living things. Plant
What is Organic Farming? | Agriculture | Biology | FuseSchool
As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more densely packed sheds to maximise milk yields, or egg production,
Rover Results on Mars | NASA Planetary Sciences
Discover the instruments that Curiosity, a rover on Mars, used to gather and analyze soil samples in this video from NASA's Jet Propulsion Laboratory. In 2012, Curiosity took its first scoop of Martian soil to test and analyze from an area called Rocknest. One of the project scientists describes how
The effect of fertilizer
The advantage of organic fertilizer over mineral fertilizer is that it not only releases nutrients, it also helps improve soil structure and provides food for the microorganisms in the soil. Author: 3sat/NANO/Labo M/Anja Kollruß/Damaris Becker/Christian Gruber/Maximilian Mohr Translation and dubbi
Rocks as water storage for plants
Plants can grow not only on soil-rich ground, but also on rocks. Due to their porosity, the rock layers lying beneath the thin upper layer of soil can store water. Author: ZDF/Terra X/Florian Roth/Thomas Kuschke/Jochen Rall/Maximilian Mohr Translation and dubbing: alugha Click here to watch more
Earthworm facts: their poop is pretty legit | Animal Fact Files
In North America, earthworms are an invasive species. They were brought over with colonizers thinking the worms would benefit the soil in the "new world." While earthworms can be quite helpful to the ground in which they live, they can also cause problems in certain ecosystems such as large northern
What Makes Things Alkali? | Acids, Bases & Alkali's | Chemistry | FuseSchool
Learn the basics about What makes things alkali? How is alkali recognized? What are alkali chemical properties? Find out more in this video! This video is part of 'Chemistry for All' - a Chemistry Education project by our Charity Fuse Foundation - the organisation behind The Fuse School. These vide
What is radioactivity
You don't see it, and you don't feel it: radiation. Nevertheless, humans are always exposed to radiation. Shielding makes sense. Natural radioactive substances in soils and rocks emit radiation. And it comes not only from the earth, but also from heaven. The higher, the stronger the cosmic rays. I
Power lines and radiation protection
The greater use of renewable energies from solar and wind requires the expansion of the electricity grids. Radiation protection plays an important role in this because electric and magnetic fields are generated by additional high-voltage lines. How great are possible loads from high-voltage lines? W
