2023年9月23日 · “Pale soil needs organic matter, fertilizing and mulching, but the soil can sustain life,” says Niewold. It is also decent for low-water plants. These soils look bleached or washed out, or can be light brown when they’re dry. It might mean your soil contains a lot of sand, or that the iron, manganese and other key ingredients have leached out.

摘要：美国土壤系统分类中的Pale-类型是用于归类发育程度高、年龄大的土壤，在比较分析了两版《土壤系统分类》及各版《土壤系统分类检索》后，概括介绍了Pale-类型的设置缘起，及其检索条件和检索顺序的修订历程，在此基础上阐述了Pale-类型设置的演变历程对中国土壤系统分类的启示。 美国自1951年开始研究土壤系统分类，经过近十年的努力形成了第7次修改草案 [1]，补充完善后公布的《土壤系统分类》 (《ST》) [2] 极大地影响了世界土壤分类格局。 受此影响，中国 …

Soil can display a wide range of colors including brown, red, yellow, black, gray, white, and even blue or green, and vary dramatically across landscapes, between the various horizons of a soil profile, and even within a single clod of soil.

2018年11月26日 · Soil color can be a useful tool for evaluating a potential garden site. If you have a healthy dark brown or black soil, great! However, a bright red, yellow, or tan soil will work, as well. Avoid pale and gray soils whenever possible, as these signal serious drainage problems that will have to be overcome.

2024年5月18日 · Pale brown/yellow soil typically indicates low organic matter and humus, which translates to poor fertility and structure, coarse particle size, and potential nutrient leaching. To address this, pale soil requires regular organic matter …

2024年3月19日 · White/Pale Soil. While/pale soils are the opposite of gray or bluish-gray soils and they’re known for high alkalinity. These soil types are frequently found in arid regions and not many plants can survive in those conditions. If your soil is white, you can enrich it with sulfur and in that way decrease pH levels. How To Interpret Soil Color

2025年3月6日 · Pale or Yellow Grass. Discolored turf — especially whitish turf — is one of the major indicators of high pH soil. Alkaline soil turns important plant nutrients like phosphorus, manganese, zinc, copper, and iron into insoluble forms. In other words, they’re in the soil but can’t be used by grass or other plants.

Soil colour can be described in general terms into commonly six colour classes – red, yellow, black, brown, grey and pale. Colour can also be objectively assessed by comparing the colour of a freshly broken surface of moist soil with the standard Munsell Soil Colour Charts.

2023年10月23日 · When your soil appears white or pale, it’s like a whispered cry for help from the earth. This color might indicate a high sand content or the leaching of essential elements like iron and manganese. In such cases, it’s time to spring into action.

2025年3月4日 · Explore the essential components of soil: air, water, and humus, their importance to living organisms, and how color, texture, and particle size determine soil properties. Soil is a dynamic and complex medium crucial for life on Earth.
