Generally, a soil nitrogen level below 10-20 ppm is considered low and may indicate that the soil lacks sufficient nitrogen for optimal plant growth. It is important to conduct soil tests to accurately determine nutrient levels and make informed decisions about fertilization.

Is catalpa a nitrogen fixer?

in the following page: http://www.gardenguides.com/plants/plant.asp?symbol=CASP8 we can see "Nitrogen Fixation: Low". with a low ratio of fixation, Catalpa is not considered a Nitrogen Fixing plant.


What is an example of acid rain changing the pH soil killing some trees?

Acid rain has a low pH indicating that it is acidic. The pH in the soil can have a detrimental effect on some trees.


Why must carnivorous plants rely on insects for their source of nitrogen?

Carnivorous plants must rely on insects for nitrogen since they are found in soils with low nitrogen levels. Since the soil can't provide them with enough nitrogen, they must consume insects to meet their nitrogen requirements.


Is the pH level of the substance low, indicating that it is acidic, or is it high, indicating that it is alkaline?

The pH level of the substance is low, indicating that it is acidic.


Why is nitrogen dioxide low at midnight?

because there are not as many cars (which mainly cause nitrogen dioxide) at night.


Why are nitrate levels low in waterlogged soil?

Nitrate levels are low in waterlogged soil because the lack of oxygen in waterlogged conditions impedes the microbial processes responsible for converting nitrogen into nitrates. This limits the transformation of organic nitrogen into nitrate form through nitrification.


Is acidic soil biotic?

Acidic soil is not considered biotic because it refers to the chemical properties of the soil, indicating a low pH level. Biotic factors, on the other hand, include living organisms like plants, animals, and microbes that interact within the soil ecosystem.


Is the pH level of the substance low, indicating that it is acidic, or is it basic?

The substance has a low pH level, indicating that it is acidic.


How do some plants that live in low-nitrogen soils get nitrogen?

Plants living in low-nitrogen soils can obtain nitrogen by forming symbiotic relationships with nitrogen-fixing bacteria that convert atmospheric nitrogen into a usable form for the plants. These bacteria can colonize the roots of the plants and provide them with the nitrogen they need for growth. Additionally, some plants can also take up nitrogen from organic matter in the soil or through the decomposition of dead plant and animal material.


Why are bogs and swamps usually low in nitrogen?

Oh, dude, bogs and swamps are low in nitrogen because they have poor drainage, so the waterlogged conditions limit the decomposition of organic matter. This means that dead stuff just kinda sits there, not breaking down efficiently and releasing nitrogen into the soil. So, like, the nitrogen cycle is all messed up in these soggy places.

Is ammonium sulphate 21-0-0 good for planting grass?

That all depends upon the soil that you have to start with. NPK stands for, "nitrogen, phosphorous, pottassium". What you are proposing has only nitrogen, but no P or K. If you send a sample of your soil to the lab for analysis, and find out that it has plenty of P and K, but is low on nitrogen, then the ammonium sulfate might just be what you need. However, in the absence of a soil analysis, I would start with a more balanced fertilizer.
