The bleached-layer soil is a layer of soil formed by the loss of clay particles and/or free iron dioxide, sometimes accompanied by the in-place condensation of iron dioxide. Its color was mainly determined by the sand particles and powder particles that formed the whiteness. The bleached layer was usually composed of bleached substances, including segregated iron-Mn agglomerations, agglomerations, and patches. The whiteness itself showed the characteristics of the color, such as a tint lower than 2, a moistened lightness greater than 3, a dry lightness greater than 6, and so on. The thickness of the blanched layer was generally between 20-30cm. Its distribution and formation in the soil are related to the clay content, iron dioxide content, water eluviation and drainage of the soil. There was a specific level of diagnosis for the bleached layer in the soil systematic classification. For example, there was a classification for the bleached layer in both the Chinese soil systematic classification and the American soil systematic classification. However, there were still some disputes and differing views on the cause and nature of the bleachers.

There are many types of soil pesticide to choose from. The following are some commonly used soil pesticide: 1. Imidacloprid: It has the characteristics of systematic absorption, high efficiency, wide spectrum of insects, long duration, etc. It is suitable for controlling piercing-sucking mouthpart pests, such as aphids, leafhoppers, planthoppers, whiteflies, thrips, etc. 2. Acetamiprid: It has the characteristics of strong internal absorption, low dosage, good quick-acting, high activity, long duration, etc. It is suitable for controlling pests of vegetables, fruit trees, potatoes, tobacco and other crops. 3. Thioxam: It has the characteristics of contact toxicity, stomach toxicity, and internal absorption activity. It has higher activity, better safety, wider pesticide spectrum, faster action speed, and longer effective period. In addition, there are other pesticides such as phoxim, high-efficiency cyhalothrin, etc., but you need to pay attention to the selection of suitable pesticides to avoid the use of organic phosphorus pesticides and high-efficiency cyhalothrin that is easy to cause allergy. It should be noted that different pests may have different reactions to different pesticides. Therefore, before using soil pesticides, it is best to understand the types of pests and choose the appropriate pesticide for spraying or soil treatment.

In 10000 BC, humans were mainly hunter - gatherers. They had to constantly search for food, following the migration of animals. People lived in small groups and made simple tools from stone, bone, and wood. Their shelters were often basic, like caves or simple huts made from branches and animal skins.

Yes. Archaeological evidence shows that by 10,000 BC, humans were in a transitional phase from being mainly hunter - gatherers to starting to develop more settled agricultural communities. There could be stories passed down through generations about this shift. Maybe stories of the discovery of new plants that could be cultivated or of how they learned to domesticate animals. These would be stories that are in a sense 'based on' the time of 10,000 BC as they reflect the major changes in human lifestyle that were taking place during that era.

Nope, '10 000 BC' isn't based on actual events. It's a imaginative creation that combines various ideas and concepts related to the distant past to form a fictional storyline.
