[1] The 16-17 nutrients in healthy soil must be in soluble form in order to be taken up by plant roots. [2] Generally, nitrogen isn't a problem. It tends to be abundant above and below ground. So it's unavailability tends to be more linked with drought conditions above and below ground. Less moisture below ground makes for less of the available nitrogen accessible to plants, which can only take in soluble nutrients. [3] Calcium and magnesium are more likely to become unavailable in acidic soil.

Nitrogen fixation is a process that changes plant and soil into nitrogen compounds?
True
Two ways by which plants get nitrogen compounds?
Some essential nitrogen compounds can be absorbed by plants from the soil in which they grow. the nitrogen compounds can be provided to the soil by nitrogen-fixing bacteria living in association with the plants and/or from fertilizers. Some nitrogen compounds can also be input to the soil from lightning strikes that provide activation energy to facilitate the reaction of atmospheric nitrogen to produce absorbable nitrogen compounds that can be carried into soil by rain.
Describe the three main plant nutrients in fertile soil?
THey are nitrogen, phosphorus, and potassium.
What does the soil provide the plant with?
These answers assume that the soil's healthy. Healthy soil provides the plant with water, food, and cover. Specifically, it does so by providing the plant with [1] protection from what can be yo-yo temperature extremes above ground. That protection is increased with above-ground mulch. Healthy soil also provides the plant with [2] pore spaces of air and moisture. [3] necessary organic material, from dead and decaying organisms. [4] 16-17 necessary nutrients, and minerals. [5] infiltrated and then drained moisture. [6] growing space, for roots. [7] beneficial organisms. For example, nitrogen-fixing bacteria and nematodes make otherwise unavailable nitrogen available in soluble form to the plant.
What do plants need from the soil?
Plants need the protective cover of soil in order for their roots to grow. Specifically, soil keeps roots from being damaged by excessive, unfiltered heat, light and winds.Plants also need the nutrients and water of soil, for overall growth. Nutrients and water from the soil are taken up through the roots, and into the shoots, for participation in photosynthesis. Photosynthesis makes possible the transformation of food from soil into the sugary and starchy energizers by which plant activities such as leafing, fruiting, and flowering are carried out.Additionally, plants need the life of the soil food web. For example, plant roots send exudates, which are the waste products of plant processes, into the soil. Plants need soil organisms to control exudate accumulations in soil. As another example, nitrogen fixing bacteria and nematodes within the soil turn present but unavailable nitrogen into the soluble forms that plant roots need for intake.
Why can't plants survive in soil that is to acidic?
acidic soil limits the availabilty of major nutrient Nitrogen. Acidic soil causes Nitrogen to held in solid form NH4+ so it is unavailable to the plant. Plants need Nitrogen in solution which is NO3-
What does it meant that nitrogen burns a plant?
Nitrogen plant burns are caused when to much fertilizer (or fertilizer with a high concentration of Nitrogen) is added to a plant. If the concentration of Nitrogen (or Nitrogen compounds such as ammonia) is to high it causes the soil to become highly acidic in the area where it was applied, the high acidity damages (or kills) the roots of the plant retarding or preventing the uptake of water or nutrients by the plant.
What plant family helps return nitrogen to the soil?
Legumes fix nitrogen in the soil.
How atmospheric nitrogen enters the soil?
Typically, atmospheric nitrogen gets into the soil by nitrogen-fixing bacteria that are symbiotic with such plants as clover, soybeans and alfalfa. Bacteria in the plant extract nitrogen from the air, and when the plants die, the nitrogen remains in the soil as the plant decays.
Which part of the plant uses nitrogen and what for?
The roots extract nitrogen from the soil.
How nitrogen in soil is detected?
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
What plant family restores nitrogen to the soil?
Legumes are the plant family that restores nitrogen to the soil. Most of legumes have symbiotic nitrogen-fixing bacteria in structures called root nodules.

Which plant enriches the nitrogen content in soil?
sugarcane
The nitrogen cycle may be described as nitrogen moving from the air to the soil where plant roots use it as food. when plants die nitrogen is returned to the air true or false?
false, when the plant dies in this case, nitrogen is returned to the soil
Why might farmers plant legumes such as peas to improve the nitrogen levels in the soil?
legumes contain high level of nitrogen which are leeched into the soil. this allows the farmer to then plant crops such as corn that use that nitrogen
