[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.

How does soil fertility and pH affect the ability of a soil to support plant life?

Soil fertility influences the availability of nutrients necessary for plant growth, such as nitrogen, phosphorus, and potassium. pH levels affect nutrient availability and can impact plant nutrient uptake, with most plants preferring a slightly acidic to neutral pH range. An optimal balance of soil fertility and pH is crucial for supporting healthy plant growth and development.


What is the washing away of nutrients from the soil?

The washing away of nutrients from the soil is called leaching. This process occurs when water carries soluble nutrients like nitrogen and phosphorus downwards through the soil layers, making them unavailable for plants to uptake. Leaching can lead to nutrient depletion in the topsoil, impacting plant growth and productivity.


What are the different ways by nitrogen in the air reaches the soil?

Nitrogen in the air reaches the soil primarily through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can use. Nitrogen can also reach the soil through precipitation, as nitrogen compounds are washed out of the atmosphere and deposited onto the soil surface. Additionally, nitrogen can enter the soil through the decomposition of organic matter, releasing nitrogen back into the soil as plant nutrients.


How does farming remove nitrogen from soil?

Farming can remove nitrogen (N) from soil in two ways:plant (crop) uptake, anderosion.Since N is an important plant nutrient, plants will remove it from the soil and incorporate the N into parts of the plant. When plant parts are harvested, that N is being removed from the soil. Plant parts that are left in the field will return a lot of the N contained in those parts to the soil.In most soils, N will be found at highest concentrations near the surface, in soil organic matter. Many farming practices increase the rate of erosion, and it is those surface horizons high in N that will be lost first.


What is the most important mineral in soil?

One of the most important minerals in soil is nitrogen. Nitrogen is essential for plant growth and is a key component of amino acids, proteins, and chlorophyll. It is often a limiting factor for plant growth, so ensuring an adequate supply of nitrogen in the soil is crucial for crop production.

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.


How is nitrogen depleted from soil?

Nitrogen can be depleted from soil through plant uptake, leaching, and runoff. Plant roots absorb nitrogen from the soil to support growth, which can lead to a decrease in soil nitrogen levels over time. Additionally, excess water can cause nitrogen to leach out of the soil and into groundwater, or runoff can transport nitrogen into bodies of water, further depleting soil nitrogen.


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.


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.

How does a soil become acidic?

Soil can become acidic due to natural processes such as weathering of minerals, leaching of basic ions, decomposition of organic matter, and acid rain. Human activities like excessive use of nitrogen-based fertilizers, mining, and industrial pollution can also contribute to soil acidity. This can impact plant growth and nutrient availability in the soil.


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
