  2. Agrominerals - Wikipedia

    en.wikipedia.org/wiki/Agrominerals

    Grinding a mineral, like olivine, to a particle size that would be effective in the ground (1μm), takes about 1.5 gigajoules per ton of rock. [3] Research will be needed to find more efficient ways to crush rock for rock-powders to be a sustainable solution for replenishing plant nutrients.

  3. Agrogeology - Wikipedia

    en.wikipedia.org/wiki/Agrogeology

    Agrogeology is the study of the origins of minerals known as agrominerals and their applications. These minerals are of importance to farming and horticulture, especially with regard to soil fertility and fertilizer components. These minerals are usually essential plant nutrients. Agrogeology can also be defined as the application of geology to ...

    Boron is available to plants over a range of pH, from 5.0 to 7.5. Boron is absorbed by plants in the form of the anion BO 3− 3. It is available to plants in moderately soluble mineral forms of Ca, Mg and Na borates and the highly soluble form of organic compounds. It is mobile in the soil, hence, it is prone to leaching.

  5. Plant nutrients in soil - Wikipedia

    The soil mineral apatite is the most common mineral source of phosphorus, from which it can be extracted by microbial and root exudates, [79] [80] with an important contribution of arbuscular mycorrhizal fungi. [81] The most common form of organic phosphate is phytate, the principal storage form of phosphorus in many plant tissues.

  6. Classification of minerals - Wikipedia

    en.wikipedia.org/wiki/Classification_of_minerals

    The classification of minerals is a process of determining to which of several groups minerals belong based on their chemical characteristics. Since the 1950s, this classification has been carried out by the International Mineralogical Association, which classifies minerals into the following broad classes: Classification of non-silicate minerals

  7. Physical properties of soil - Wikipedia

    en.wikipedia.org/wiki/Physical_properties_of_soil

    As the primary minerals in soil parent material weather, the elements combine into new and colourful compounds. Iron forms secondary minerals of a yellow or red colour, [117] organic matter decomposes into black and brown humic compounds, [118] and manganese [119] and sulfur [120] can form black mineral deposits. These pigments can produce ...

  9. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality. [3] It also refers to the soil's ability to supply plant/crop nutrients in the right quantities and qualities over a sustained period of time.
