Amazing facts in Agricultural Science

Peanuts are legumes and not nuts

Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments

Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them

Cows have got the ability to walk up stairs, but not down stairs

A group of cows is called a team, drove or herd.

People just prefer to call them herd


NOTABLE POINTS IN Agricultural Science

Below are some common types of erosion:

  • Water Erosion: It is caused by rainfall and flooding on the topsoil. As a result of water erosion, some layers of the topsoil are lost.

  • Sheet Erosion: When an entire surface of land becomes eroded at a uniform (equal) level, such is referred to as sheet erosion. It is shown below:
    Sheet Erosion - Len Academy

  • Wind Erosion: It results from the actions of wind on a bare land. Wind erosion is often seen in deserts. Overgrazing and lack of vegetation cover will also enhance wind erosion on topsoil.

Please read more on types of soil erosion here.

Soil erosion is defined as a process through which the topsoil is removed or moved from one point to another by agents like wind, water, man and animals.

Soil erosion occurs naturally (wind and water) and may also be facilitated by living organisms.

Soil erosion is more likely to occur on a sloppy land and land with no vegetation cover. When this occurs, the nutrient rich layer of the topsoil is washed away; and this ultimately results in fewer plants growing on such eroded soil.

There are about 630 different kinds of carnivorous plants.

Carnivorous plants are plants that derive some or most of their nutrients by consuming small animals, especially insects.

Carnivorous plants are also referred to as insectivorous plants.

Examples of carnivorous plants include sundew and Venus flytrap.
