The levels of nitrogen and phousphorus in fields decline when crops are harvested because the diversion of nitrates and phouspate would deplate the soil unless the farmer replaced the missing nutrients.
Hope this helped :)
well, by rotating the fields, the farmers give the soil a chance to naturally restore nitrogen and other nutrients.
They excelled in fields dominated by men.
No
because...
They have to do a lot of work in the hot fields
No, the moo is a sound used by cattle to communicate. However, the feces (poo) can be harvested and is being recycled in several inventive ways to reduce nitrogen and phosphorous contamination of fields and waterways.
Fields, storage, where it is harvested
It is an area of industrial decline, In the fields of steel making and other industrial fields.
plants need nitrogen to grow thats why in ponds there is alot of plants cuz the nitrogen runs off from the fields!!
Rice is grown in waterlogged paddy fields. I doubt if any other food crop would be grown after the rice has been harvested.

nitrogen
Because for many crops, nitrogen is probably the single most important plant nutrient.
Yes. Soybeans are grown in large fields and harvested with combine harvesters. Soybean has been a crop for the Southern USA.
well, by rotating the fields, the farmers give the soil a chance to naturally restore nitrogen and other nutrients.
Because they are told to by the Government.
By increasing the size of fields there is less wated space therefor more crop is harvested and it is more efficient use of the land Bigger fields are more efficient to care for. You spend less time moving the tractors and harvesters around, and more time working the soil.
