  2. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Phosphorus is a primary factor of soil fertility as it is an element of plant nutrients in the soil. It is essential for cell division and plant development, especially in seedlings and young plants. [10] However, phosphorus is becoming increasingly harder to find and its reserves are starting to be depleted due to the excessive use as a ...

  3. Phosphorus deficiency - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_deficiency

    Planters add phosphorus into soil with bone meal, rock phosphate, manure, and phosphate-fertilizers. Introducing these compounds into soil however does not ensure the alleviation of phosphorus deficiency. There must be phosphorus in the soil, but the plant must also absorb the phosphorus. Phosphorus uptake is limited by the chemical form of the ...

  4. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    Plants can increase phosphorus uptake by a mutualism with mycorrhiza. [6] On some soils, the phosphorus nutrition of some conifers, including the spruces, depends on the ability of mycorrhizae to take up, and make soil phosphorus available to the tree, hitherto unobtainable to the non-mycorrhizal root. Seedling white spruce, greenhouse-grown in ...

  5. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...

  6. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Soil acidification refers to the process by which the pH level of soil becomes more acidic over time. Soil pH is a measure of the soil's acidity or alkalinity and is determined on a scale from 0 to 14, with 7 being neutral. A pH value below 7 indicates acidic soil, while a pH value above 7 indicates alkaline or basic soil.

  7. Agrogeology - Wikipedia

    en.wikipedia.org/wiki/Agrogeology

    A common problem faced in agriculture is dealing with soils lacking in phosphorus. Phosphorus, along with nitrogen and potassium, is an important element in determining plant development and health. A high percentage of traditional fertilizers intended to mend phosphorus-deficient soils end up becoming insoluble complexes in the soil.

  8. Soil - Wikipedia

    en.wikipedia.org/wiki/Soil

    Water is a critical agent in soil development due to its involvement in the dissolution, precipitation, erosion, transport, and deposition of the materials of which a soil is composed. [39] The mixture of water and dissolved or suspended materials that occupy the soil pore space is called the soil solution. Since soil water is never pure water ...

  9. Phosphorus - Wikipedia

    en.wikipedia.org/wiki/Phosphorus

    Phosphorus can be transferred from the soil in one location to another as food is transported across the world, taking the phosphorus it contains with it. Once consumed by humans, it can end up in the local environment (in the case of open defecation which is still widespread on a global scale) or in rivers or the ocean via sewage systems and ...
