The best type of soil for agricultural purposes is loam. Loam soil has rock particles of many different sizes. This results in many pockets that can hold air or water, which keeps the soil loose enough that plants can grow into it easily.
Beans grow better in soil because soil has all the moisture and nutrients. If you use sand, it could be to rocky. Clay will also not be good even though it can keep good moisture it does not have the nutrients like soil.
in GENERAL a humus rich soil is better for plant growth, but it is dependant on the type of plant - e.g. plants that grow at the coast are at home in very sandy soils.
It all depends on the plant. Many types of plants prefer different types of soil. For example, a spider plant would like a good potting soil mixture whereas a jade would like something more well-draining and sandy.
It is not recommended to make potting soil with sandy soil alone. Sandy soil tends to provide poor water retention and nutrient retention, which are crucial for plant growth in containers. It is best to blend sandy soil with organic matter like compost, peat moss, or perlite to improve its water-holding capacity and nutrient content for potted plants.
Pea plants can grow in sandy soil, but they may not thrive as well as they would in soil with better water retention and nutrient content. Sandy soil drains quickly and can lead to moisture stress for pea plants if not watered regularly. Adding organic matter or compost to sandy soil can help improve its water and nutrient holding capacity, which would benefit pea plant growth.
Potting soil or mix is usually better as garden soil tends to bake hard in a pot, or not hold enough nutrients for the plant. Drainage can be a problem. Certain plants need special types of mix, such as orchids and African Violets. Be careful just growing plants in potting soil. Potting soil drains badly and even in direct sunlight. Not all are this way but some are. The best thing for potted plants is to experiment and mix topsoil and potting soil till you get the best drainage for the particular plant you are working with. For plants that like more moist soil, euse more potting soil, for less, more topsoil. A friend asked me to look at some of his plants and asked why they were dying. They were outside in pots and in 100% potting soil. The roots on the plants were rotting because of the water was not draining because of the density of the soil when saturated. We added about 30-40% sand to the mix and it did the trick. Not all potting soils are made the same though. Just remember what a plant needs. Sunlight, nutrients and water. The soil mix can change but the basics remain the same.
Generally no. Sand is very poor at holding water and nutrients. Some plants are adapted to light sandy soils and may grow better there than most other species.
Soil that retains water and gives daffodils "wet feet" will cause bulb rot and the plants/bulbs will die. Sandy soil is well drained and slightly acidic and that is a favorite of daffodils. Sandy soil will also make for slightly taller daffodils, which are preferred if you like cut flowers.
Sandy soils have little moisture and few nutrients. Therefore, most plants can't grow well. Adapted plants such as cactus have evolved to grow in sandy soil.
It depends on what you would be using it for, so define the question.
