How do plants and animals get nitrogen if not from the atmosphere?
if not from the atmosphere , they must depend on a process called nitrogen fixation. They get it from the soil. That's why farmers add fertilizer to the soil to increase nitrogen content
Explain why not planting a crop and then ploughing in the fall might help a farmer restore nitrogen and phosphorus levels in the soil?
When the plant stores the nitrogen in the roots, it produces a lump on the root called a nitrogen nodule. The roots can reserve the Nitrogen and Phosphate for a very long time.
Does soil contain nitrogen?
Yes, soil does contain nitrogen.
What would happen to nitrogen cycle if plants were removed by pesticides?
Pesticides stop the nitrogen cycle by suppressing nitrogen-fixing bacteria from replenishing natural nitrogen fertilizer in soil. This results in lower crop yields, stunted growth, and an ever-greater need for additives to boost production.
What plant family helps return nitrogen to the soil?
Legumes fix nitrogen in the soil.
Which plant enriches the nitrogen content in soil?
sugarcane
Why urine used to fertilize plants?
because urine contains urea which enriches the soil with nitrogen content.
How do you make working models on nitrogen fixing in agriculture?
sowing ground nut after rice crop is the surest means of enhancing nitrogen content of the soil.
What crop can replace nitrogen in soil so it will retain its fertility?
Generally leguminous plants i.e.,plants of Family Fabaceae have root nodules inhabited by nitrogen fixing bacteria such as Rhizobium leguminosarum,which retains and increases the nitrogen content in the soil.
What do farmers apply to land or soil to increase nitrogen?
They can either a) spread a nitrogen based fertilizer, or b) rotate to a crop that replaces the nitrogen in the soil.
What essential crop nutrient do beans add to the soil?
Nitrogen.
The nutritional content of the soil can be maintained or improved by?
crop rotation
How can you improve the nitrogen content in your soil?
malay ko..
Why do farmers plant alfalfa or clover but don't harvest it?
Both clover and alfalfa are "nitrogen fixing" plants, meaning they have the riboza bacteria in their roots which converts atmospheric nitrogen into a form which can be used by plants and then animals. Planting either crop naturally enriches the soil without the use of artificial fertilizers. Allowing the plants to decompose in the field releases this nitrogen.
How much does a nitrogen based fertilizer increase the acidity level of the soil on a grass crop?
How much nitrogen per square metre have you put on the soil??
How much nitrogen is left in the soil after harvesting a leguminous crop?
It depends on:How much nitrogen was in the soil before the legume was plantedNitrogen-holding capacity of the soil typeHow much nitrogen was washed away by precipitation during the seasonWhich legume crop was grownHow efficient the bacteria nodulation wasThis is why soil testing is so important.
The nutritional content of the soil can be improved by?
crop rotation :) trust me i know
