why are desert soils low in organic matter brainly?

Answer Expert Verified A. The temperatures are too high. ... A desert is a region with extremes of temperatures and little to no rainfall. Organic matter are the remains of organisms that have died.

And one of the very best sources of organic matter is autumn leaves. Leaves are packed with trace minerals that trees draw up from deep in the soil. When added to your garden, leaves feed earthworms and beneficial microbes. They lighten heavy soils and help sandy soils retain moisture.

Sandy Soil: Advantages and Disadvantages. Sandy soils are light and gritty to the touch. Because sandy soils have large particles, they dry out quickly, are often low in nutrients and acidic. Both water and fertilizer have a tendency to leach out of the soil - escaping to waterways before the plant can utilize them.

The soil bulk density (BD), also known as dry bulk density, is the weight of dry soil (Msolids) divided by the total soil volume (Vsoil). The total soil volume is the combined volume of solids and pores which may contain air (Vair) or water (Vwater), or both (figure 1).

Of all the components of soil, organic matter is probably the most important and most misunderstood. Organic matter serves as a reservoir of nutrients and water in the soil, aids in reducing compaction and surface crusting, and increases water infiltration into the soil. Yet it's often ignored and neglected.

Soil colour Black/dark brown soil usually indicates the presence of decaying organic matter so is generally fertile. Pale brown/yellow soil often indicates that organic matter and nutrients are low and this generally means poor fertility and structure. Pale soil needs plenty of organic matter and mulching.

Organic material is anything that was alive and is now in or on the soil. For it to become organic matter, it must be decomposed into humus. Humus is organic material that has been converted by microorganisms to a resistant state of decomposition.

A desert is neither biotic or abiotic. A desert is an ecosystem made up of biotic elements (plants, animals) and abiotic elements (sand, rocks etc.)

Organic matter is found in living, or once-living, organisms, so it is biological in nature. Inorganic matter is generally obtained from non-living matter, so it is mineral in nature. Inorganic compounds are less complex than organic compounds. The presence of carbon prevents organic compounds from forming salts.

In the desert, extremely low rainfall, lots of sunlight, and limited water sources are abiotic factors. ... Biotic factors in the desert like plants and animals have specific adaptations that allow them to move through the sand, keep cool, and conserve water.

The clay soil had the highest water holding capacity and the sand soil had the least; clay>silt>sand. Clay particles are so tiny and have many small pore spaces that make water move slower (the highest water holding capacity). Sandy soils have good drainage but low water and nutrient holding capacities.

The simple answer is that dirt is mixture of a whole lot of “stuff” such as rocks, sand, clay, and organic matter. ... Rocks are responsible for soil texture and, sometimes, alkalinity. Soils produced from limestone are often finely textured, neutral to alkaline and fertile.

Biosolids contain organic matter which helps to maintain an open, porous, soil structure. It helps to improve the workability and drainage of heavy soils, reducing the risk of soil compaction. It also increases the water-holding capacity of light soils, reducing drought risk in periods of prolonged dry weather.

Many plants and animals exist in the desert, contrary to common belief that deserts are empty and sustain little life. Scorpions, coyotes, snakes, spiders, lizard, and cacti are just a few of the biotic factors. One of abiotic factors is the sand.

['Clay soils are heavy, high in nutrients, wet and cold in winter and baked dry in summer.', 'Sandy soils are light, dry, warm, low in nutrients and often acidic.', 'Silt soils are fertile, light but moisture-retentive, and easily compacted.', 'Loams are mixtures of clay, sand and silt that avoid the extremes of each type.']

Soil texture describes the proportion of the soil particles and the fineness or coarseness of a soil. ... Sand, silt, clay, and organic matter particles in a soil combine with one another to form larger particles. Soil structure is the arrangement of the soil particles into aggregates of various sizes and shapes.
