Without enough nitrogen, and minerals such as phosphorus and potassium, plants cannot create the molecules they need to grow and function. Soils without these elements (and others) have to be fertilized to grow crops. Growing certain crops can also restore at least some of the nitrogen.
Some plants have adapted to nutrient-poor soils, such as the Venus flytrap, which gets organic material from insects it traps.
Because the soils are generally nutrient poor
It is a mixture between latish soil (of the tropical regions) and siernozem (desert).
Clay soils.
Nutrient-poor soils are typically found in biomes such as deserts, tundras, and some types of grasslands. These biomes have limited vegetation cover and lack enough organic matter to support nutrient cycling.
Desert soils are typically sandy or sandy-loam soils with low organic matter content. They have low moisture retention capacity and are often nutrient-poor. These soils are formed through the weathering of rocks and minerals in arid environments.
Soil is nutrient-poor and acidic. Decomposition is rapid and soils are subject to heavy leaching.
Tropical soils are generally poor and thin due to high temperatures and heavy rainfall that cause rapid weathering and leaching of nutrients. This results in low organic matter content and limited nutrient availability for plant growth.
Generally, lowland soils are younger than upland soils due to deposition and erosion processes in low-lying areas. Lowland soils are often formed from recent sediments and are more fertile, while upland soils have had more time to weather and develop, making them older and potentially more nutrient-poor.
the tropical rainforest has nutrient poor and acidic soil because of rapid decompisition, an extreme chemical weathering/leaching because of the high amounts of rainfall. Hope this helps :)
The taiga biome is characterized by acidic and nutrient-poor soils known as Podzols. These soils are typically low in fertility due to their extensive leaching and acidic nature, making it challenging for plants to grow.
It means that the soil lacks good nutrients
Rainforest soils are generally shallow, typically ranging from about 10 to 30 centimeters deep. However, the depth can vary depending on specific locations and environmental conditions. These soils are often nutrient-poor due to rapid decomposition and nutrient uptake by dense vegetation. As a result, most nutrients are found in the organic layer rather than deep within the soil profile.
