  2. Infiltration (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Infiltration_(hydrology)

    The maximum rate at that water can enter soil in a given condition is the infiltration capacity. If the arrival of the water at the soil surface is less than the infiltration capacity, it is sometimes analyzed using hydrology transport models, mathematical models that consider infiltration, runoff, and channel flow to predict river flow rates ...

  3. Iron deficiency (plant disorder) - Wikipedia

    en.wikipedia.org/wiki/Iron_deficiency_(plant...

    If soil iron concentration is high, in spite of this it can become unavailable for absorption if soil pH is higher than 6.5. [1] Excess of elements such as manganese in the soil can interfere with plant iron uptake triggering iron deficiency. [2] Iron is needed to produce chlorophyll, hence its deficiency causes chlorosis.

  4. Leaching (agriculture) - Wikipedia

    soil type and structure. For example, sandy soil holds little water while clay soils have high water-retention rates; the amount of water used by the plants/crops; how much nitrate is already present in the soil. [3] The level of nitrous oxide (N 2 O) in the Earth's atmosphere is increasing at a rate of 0.2 to 0.3% annually.

  5. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    If the water potential is more negative in the plant than the surrounding soils, the nutrients will move from the region of higher solute concentration—in the soil—to the area of lower solute concentration - in the plant. There are three fundamental ways plants uptake nutrients through the root:

  6. Water balance - Wikipedia

    en.wikipedia.org/wiki/Water_balance

    [2] [3] In hydrology, a water balance equation can be used to describe the flow of water in and out of a system. A system can be one of several hydrological or water domains, such as a column of soil, a drainage basin, an irrigation area or a city. The water balance is also referred to as a water budget. Developing water budgets is a ...

    When it comes to prevention, eating a well-balanced diet that incorporates iron-rich foods can lower your risk of developing iron deficiency. Because pregnancy and menstruation can take tremendous ...

  9. Cation-exchange capacity - Wikipedia

    en.wikipedia.org/wiki/Cation-exchange_capacity

    Cation-exchange capacity (CEC) is a measure of how many cations can be retained on soil particle surfaces. [1] Negative charges on the surfaces of soil particles bind positively-charged atoms or molecules (cations), but allow these to exchange with other positively charged particles in the surrounding soil water.
