Arrange the soil on the basis of decreasing fertility: 1 Red soil; 2 Desert soil; 3 Black soil; 4 Laterite soil; 5 Alluvial soil? ›

Alluvial soil is the most fertile soil, followed by black soil, red soil, laterite soil, and desert soil.

The Laterite soil is less fertile as compared to the other soils. Thus, the correct answer is option (C). Note: The soil with poor fertility status lacks moisture as the leaching process enables moisture to go down.

Gravel, silt, sand and clay.

-Red soil is not very fertile soil because it is low in humus and nutrients. Red soil is difficult to cultivate as it has low water holding capacity.

Scientists attribute soil formation to the following factors: Parent material, climate, biota (organisms), topography and time.

Alluvial soil is the most fertile soil, followed by black soil, red soil, laterite soil, and desert soil. Its fertility depends on its minerals and organic content. In general, the fertility of a soil depends on the climate and geographical terrain of its region.

Lateritic soils are characterized by their low soil fertility. Due to the high rate of weathering, and resulting low charge minerals, the soil is unable to retain the nutrients needed for the growth of plants.

Alluvial soil is formed by deposition of alluvium and sediments carried by rivers and sea waves over many years, which make this soil very fertile. It consists of various proportions of sand, silt and clay. It is also rich in organic nutrients.

In simple words, descending order is defined as an arrangement in the highest to lowest format. These concepts are related to decimals, numbers, fractions or amount of money. 24, 20, 18, 12, 7 are arranged in descending order. This is also known as decreasing order of numbers.

What is decreasing order from largest to smallest? ›

from the largest value to the smallest value is known as descending order. We can arrange these numbers in decreasing order of their value. Descending can also be thought of as climbing down the stairs of numbers starting from the highest value.

The driest soils, in deserts, have very little organic matter because there is not enough water to support a large or diverse plant community. Desert soils are nutrient poor because of the low organic matter and because the lack of water slows the weathering process that can release nutrients from soil minerals.

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. Red soil usually indicates extensive weathering and good drainage, but often needs nutrients and organic matter.

Low desert soils usually have a high clay content, low organic material content (less than 1%) and a high pH, meaning the soil is very alkaline (salty). The high clay content helps the soil to retain water and nutrients.

A fertile soil maybe natural or inherent and it can be acquired by artificial fertilizers or manures. Fertility of soil can be affected by physical, chemical or biological factors ultimately having an impact on plant growth. Nutrients like nitrogen, phosphorous, sulfur as well as carbon etc.

The central or primary reason (that something is the case) A cause, explanation, or justification for an action or event. The core or basis for something.

Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
