In this way it can help in reducing the soil erosion. Thus putting lesser pressure on the soil. Primary budding varieties of crops take really very less time to mature. This very method gives surety that at no time of the year the entire area is left bare or exposed. Numerous yields ripen at diverse times of the year and are harvested at intervals. Some strips may be allowed to lie fallow while in others different crops may be sown e.g., small tree crops, grains, grass legumes, etc. Parallel to one another, crops may be cultivated in alternate strips. This practice takes away certain elements from the soil, making it infertile and exhausted rendering it unsuitable for that crop. In India, peasants grow a particular crop in the same field year after year. Roughly the context is described below:Īs the name suggests, it is rotating crops. We can save a lot of our valuable soil by bringing about certain changes in our agricultural practices. Water speed can be checked and it considerably saves soil from erosion. Soil erosion which happens maximum by river floods can be avoided by constructing dams across the rivers. One of the scientific methods to check soil erosion.
Alternate fodder crops should be grown in larger quantities. One can earmark separate grazing grounds. But overgrazing of forests and grasslands by animals, especially by herds and flocks of sheep, goats, should be properly checked. Nevertheless, it was raised to 33 per cent in the second five-year plan the proportion being 20 per cent for the plains and 60 per cent for hilly and mountainous regions. 20 to 25 per cent, as they say, is the minimum area of forest land for the whole country which is considered healthy for soil and water conservation. Undiscriminating trees cutting should be stopped and efforts should be made to plant trees in new areas. One of the best ways to conserve soil is to increase the area under forests. In our country, soil erosion has been continuing over for such a long time that it has assumed alarming proportions.įollowing methods are normally adopted for conserving soil: The new total is 360.All those measures that include help in protecting the earth from destruction and exhaustion are known as soil conservation. For example, if the current total is 300 and you enter +20%, the calculator will find 20% of 300 (which is 60) and will add that number to the total. You can also input numbers with a trailing % sign to make the operand a percentage of the current total. Use + - * and / keys for addition, subtraction, multiplication and division respectively. You can use your keypad to insert any operator before your number entry.
If you input only numbers and hit enter, the calculator will add the numbers. If you want to enter exactly 52 inĪuto decimal modes, the default function is addition (+). For example, if you enter 5236 inĪuto decimal mode and hit the Enter key, the calculator will insert a decimal point before the last two digits so your entry becomes 52.36. auto decimal mode is the same as auto mode but assumes your entry has 2 decimal places.auto mode allows you to use this adding machine with only your keypad, using numbers, decimals, operators, and the Enter key.There is a memory limit of 100 entries but you can click the "Reset" button to clear all entries and start fresh. Print the adding machine "tape" to save a record of your calculations. Input values and operators in the calculator, and review your math above. This adding machine calculator is useful for keeping a running total or "paper tape" when adding or subtracting money as in balancing your checkbook, doing your taxes, or any other calculation where you need to double check your entries.
