WORLD HISTORY

Detailed explanation-1: -Rotation can also improve soil structure and fertility by alternating deep-rooted and shallow-rooted plants. The Norfolk System, as it is now known, rotates crops so that different crops are planted with the result that different kinds and quantities of nutrients are taken from the soil as the plants grow.

Detailed explanation-2: -Crop Rotation Now, by rotating crops, fields were seeded with a different crop each year so as not to drain the fertility out of the soil. They were planted with wheat one year, root crops (such as turnips) the next, and clover the third, greatly increasing productivity.

Detailed explanation-3: -Crop rotation has been used by farmers for generations to improve grain yields by regenerating the soil and breaking the cycles of weeds, diseases and insect damage to crops.

Detailed explanation-4: -The increase in the food supply contributed to the rapid growth of population in England and Wales, from 5.5 million in 1700 to over 9 million by 1801, although domestic production gave way increasingly to food imports in the 19th century as population more than tripled to over 32 million.

Detailed explanation-5: -Crop rotation helped soils maintain particular nutrients for a variety of crops, thus allowing for soil sustainability over time. Instead of using plots of land for the same crops every year, farmers began to rotate their crops, based on nutritional needs of the crops being planted each year.

Detailed explanation-6: -Crop rotation helps in restoring lots nutrients of the soil as first the crop plants use up all the nitrogen in the soil . to restore the nitrogen the farmers plant a leguminous plant which contains bacteria which changes the atmospheric nitrogen in usable nitrogen compounds than being used up by the crop plants.
