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 :)

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.


How can phosphorus and nitrogen levels in water be controlled?

Phosphorus and nitrogen levels in water can be controlled through measures such as nutrient management practices, implementation of vegetative buffers, and regulating discharges from point sources like agricultural fields and wastewater treatment plants. Additionally, reducing runoff from urban areas and promoting sustainable agricultural practices can help mitigate the influx of these nutrients into water bodies.

What is the process by which nitrogen and phosphorus enter water by humans?

Humans contribute nitrogen and phosphorus to water through activities like agriculture (fertilizers), sewage discharges, and industrial activities. These nutrients can run off into water bodies from fields, sewage treatment plants, and factories, leading to nutrient pollution which can cause harmful algal blooms and disrupt ecosystems. Implementing better management practices and reducing nutrient inputs can help minimize this impact.

Which two things can be lead to there being too much nitrogen on the fields?

Excessive application of nitrogen-based fertilizers can lead to an accumulation of nitrogen in the soil. Runoff from agricultural fields containing nitrogen-rich compounds can also contribute to excess nitrogen in water bodies, leading to environmental issues like algal blooms.


What is applied to replace soil nitrogen crop fields?

Fertilizers containing nitrogen, such as ammonium nitrate or urea, are commonly applied to crop fields to replace soil nitrogen levels. These fertilizers provide plants with the necessary nutrients for growth and development. Additionally, crop rotation and planting legumes, which can fix atmospheric nitrogen into the soil, are other strategies used to replenish soil nitrogen.


How do phosphorous and nitrogen move from land into the ocean?

Phosphorus: Chemical weathering and physical weathering are two types of weathering involved in the phosphorus cycle. In chemical weathering, a chemical reaction causes phosphate (A phosphate is a salt of phosphorus acid) rocks to break down and released by lichens can cause chemical weathering. In physical weathering, processes such as wind, rain, and freezing release particles of rock and phosphate into soil. However, most phosphate in run-off settles on lake and ocean bottoms and will not enter the biotic community unless the sediment is disturbed.Nitrogen: Excess nitrate and ammonium that are not taken up by plants mix with rainwater and are washed from the soil into the ground water and streams. This unused nitrogen may settle to ocean, lake, or river bottoms in sediments. Eventually, these sediments will form rock and the nitrogen will not be available. Only after centuries of weathering will the nitrogen be released into the water.
