Because the growing of a crop removes vital plant foodstuffs from the soil and these must be replaced or subsequent crops will reduce in quality and quantity.

Why is crop rotation vital to agriculture?
Without crop rotation, crop yields would drop rapidly over just a few years, and farmers would not be able to produce enough food, feed, fuel and fiber for us. Even if they could find ways to still keep yields up, it would greatly increase prices of all those things.
How was nitrogen originally used or what was its purpose?
Fertilizing,increases crop yields.
How can soil fertility be maintained?
soil fertility can be obtained if: farmers ensure that plant nutrients and organic matter are added back to the soil from time to time. farmers carry outbood cuktural practices to reduce or prevent the loss of soil nutrients. famers increase soil nutrients
How did the crop rotation system increase crop yields?
Crop rotations increase crop yields by improving soil conditions and reducing weed and insect populations. Rotations also help producers use conservation tillage successfully. A well- planned crop-rotation system can help producers avoid many of the problems associated with conservation tillage, such as increased soil compaction, perennial weeds, plant diseases, and slow early season growth.
Why is ammonium nitrate useful as fertilizer?
Nitrogen is absolutely essential for life and is a main component of any fertilizer. Ammonium Nitrate has tow nitrogens and is extremely soluble making it very easy to deliver to the plant/crop.
Why do farmers increase crop yields?
Higher yields = increased income.
How do farmers insure future harvest?
They can buy crop insurance to insure 25% of their crop if it is destroyed by hail later in the season. They also fertilize to ensure high yields and a good crop stand (amount)
What can farmers add to their crop to help them grow healthily?
Fertilizer or manure.
How do Japanese farmers achieve high crop yields?
They use Fertilizers and modern machinery
Why you should do crop rotation practices in place of fertilizers?
For best crop yields, crop rotation cannot take the place of fertilizer use. Most crops can only put back a portion of the nutrients they use, unless nothing is removed from the field. If you take something away, you have to put something back, whether it is an organic fertilizer (manure or compost) or an industrial chemical fertilizer. Crop rotation is better for the soil, though, so less fertilizer is needed.
How did the Mayan calendar help farmers to plant and harvest crops?
The Mayan calendar helped farmers by marking significant agricultural events and guiding planting and harvesting schedules based on celestial cycles. By aligning their agricultural activities with the calendar, farmers could maximize crop yields and ensure food security for their communities.

What can farmers use to ensure their crops get enough minerals?
farmers often use fertilisers, the fertiliser contains the phosphorus, nitrogen and potassium the crops need and the fertiliser just replenishes the minerals in the soil so the crop has enough minerals
