Want this question answered?
All i know about soils and minerals is that plants need them to stay alive. I know its not helpful. Sorry. :(
The pitcher plants, flycatchers, sundews, etc, are plants that tend to grow in nutrient poor soils. By feeding on insects the plants get all the nutrients they need for growth.
When there is soil erosion, there is depletion of top soil which in turn makes it impossible for plants to grow well. Plants need humus and top loam soils or black cotton soils for them to grow normally.
Pitcher plants get their nutrients mainly from the insects that they trap. So they don't need to depend on the soil for nutrients.
they need water, and sunlight. Also, pleanty of care.
Plants and animals need different things because they have different needs. Plants need sunlight because they make their own food and animals need plants.
Lots don't.
It's Loam a perfect mixture of clay, silt, sand, and organic matter.

Yes, plants grow best in soils with certain pH values, though optimal pH varies with the plant. Animals usually need to maintain an internal pH close to 7.
Plants cant get the water they need from dry or frozen soil. Plants in dry soils develop ways of storing water tubers and fat stems for instance.
The ericaceous type is the kind of compost that hydrangeas need for repotting. The shrubs in question prefer soils whose pH level is slightly acidic. They therefore require the kinds of amendments, composts, fertilizers, mulches, and soils favored by azaleas, heathers, and rhododendrons.
