Chemical composition: Its main components are inorganic and organic components. For example, every single single organism that is in the process of decay that come from a living thing or inorganic that is components that come from nonliving things like rocks


Importance: The importance of mixed soil is that it has more vitamins and different components than regular soils which help with the cultivation of a big variation of plants. This type of soil nourishes plants.
Besides mixed soil has a surface of plant residues that protects it from: rain, sun, and wind.

Crops that can grow there: Lettuce, chard, snap beans,rice because it holds water. Brussels sprouts and cabbage

It is made up almost entirely of decomposed plants and other organic materials. It provides most of the nutrients plants need along with trace amounts of metals and minerals. Humus is the most nutritious component for soil. Containing necessary fats, proteins and sugars.  

It supplies nitrogen, phosphorus, potassium and magnesium to soil and plants.

Chemical Composition: Sandy soils are the result of the weathering and disintegration of a variety of rocks such as granite, limestone and quartz. The components of the sand may vary depending on the conditions. 

Importance according to their functionality: Sandy soil is important for growing vegetables and fruits because it drains well. Plant root systems cannot spread well in dense, heavy clay soil. Sandy loam is the description often given for optimum garden soil.

Crops that can grow there: Although easy to cultivate and work, light sandy soils dry out quickly and are low in nutrients. When gardening on sandy soil it is important to select plants that will be happy in dry, infertile soils, as other plants will depend on expensive and environmentally questionable heavy watering and feeding. Our top 5 plants for sandy soils Lavandula, Geranium ROZANNE 'Gerwat' AGM, Buddleja, Verbena bonariensis, Choisya ternata AGM

It is different from other composts and organic fertilizers because it´s decomposition process is more advanced; this is because of the level of fungi and bacteria.

Contains a range of microorganisms that break down plant waste and help roots absorb nutrients from the soil.

Any kind of plant can grow here because it has enough nutrients. 
But mostly crops like: Fruits, Potatoes, Legumes, Rootcrops, Leafy Vegetables, etc....
