Answer:
What is soil nutrient leaching?
In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Leaching may also refer to the practice of applying a small amount of excess irrigation where the water has a high salt content to avoid salts from building up in the soil (salinity control).
Explanation:
Furthermore, how does soil leaching occur? Leaching occurs when the air spaces in soil become filled with water and gravity begins to move water downward. The percolating water carries any soluble salts that are present in the soil and is not specific for nitrate.
Similarly, you may ask, what is meant by leaching process?
Leaching is a process of extracting a substance from a solid material that is dissolved in a liquid. This process is commonly referred to as extraction, particularly in the chemical industry. Three basic steps are involved in the leaching process: contact, separation, and extraction.
What are the effects of leaching?
Leaching removes vital nutrients and micronutrients, such as water-soluble boron, from the soil, causing potential deficiencies in crops. For example, when crops suffer from boron deficiency, they exhibit visual symptoms including: Misshapen, thick, brittle, small leaves. Short stems and a "shrunken" appearance.
Answer:
D. They are made of some of the same matter.
Explanation:
Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
