How do nitrates get into the surface water

Biology
1 answer:
loris [4]4 years ago
3 0
Natural levels of nitrate in Minnesota groundwater are usually quite low (less than 1 milligram per liter [mg/L] of nitrate-nitrogen). However, where sources of nitrate such as fertilizers, animal wastes, or human sewage are concentrated near the ground surface, nitrate may seep down and contaminate the groundwater. Elevated nitrate levels in groundwater are often caused by run-off from barnyards or feedlots, excessive use of fertilizers, or septic systems.

Wells most vulnerable to nitrate contamination include shallow wells, dug wells with casing which is not watertight, and wells with damaged, leaking casing or fittings.

Nitrate contamination of a well is often regarded as a first sign of deteriorating groundwater quality.

What are the different types of farming practices
givi [52]
The different types of farming practices is ranching, dry and irrigated farming, mixed farming, single and multi-crop farming, diversified and specialized farming are all types of farming. Specialized farming can be further broken down into dairy farming, raising sheep or raising cattle.
Ranching is the practice of grazing animals on public lands and may also include raising livestock on public land. Ranching is commonly practiced in Australia, Tibet and in the hillier regions of India. Specialized farming that focuses on raising sheep, cattle or other animals, however, doesn’t utilize public lands for grazing.
Single and multi-crop farming are types of specialized farming. Specialized farming can also refer to farms that only grow 2 or 3 crops in order to maximize profits. By producing their crops on a large scale, the farmers are capable of bulk production.
Specialized farming has some handicaps in that it’s dependent upon a favorable market. Having only a few types of crops can backfire if the crops fail as well. In addition, specializing can have a negative impact on the soil.
Mixed farming refers to mixing enterprises on a single farm, such as a dairy farm that also raises livestock. It’s a type of diversified farming that usually focuses on multiple crops or specialties that support one another. Diversified farming has the advantage of providing year-round labor, but too much diversification can lead to mismanagement and neglect of certain enterprises.
