  2. Sand-based athletic fields - Wikipedia

    en.wikipedia.org/wiki/Sand-based_athletic_fields

    Highly maintained areas of grass, such as those on an athletic field or on golf greens and tees, can be grown in native soil or sand-based systems. There are advantages and disadvantages to both that need to be considered before deciding what type of soil to grow turf in. [4] Native soils offer many positive qualities, such as high nutrient holding capacity, water holding capacity, and sure ...

    en.wikipedia.org/wiki/John_Innes_compost

    John Innes compost is a set of four soil-based formulae for growing media, developed at the former John Innes Horticultural Institution (JIHI), now the John Innes Centre, in the 1930s and released into the public domain. The formulae contain loam, peat, sand, and fertiliser in varying ratios for specific purposes. These composts are used to ...

    Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical, and biological properties. It is commonly prepared by decomposing plant and food waste, recycling organic materials, and manure.

  5. Soil management - Wikipedia

    en.wikipedia.org/wiki/Soil_management

    Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...

  6. Soil fertility - Wikipedia

    en.wikipedia.org/wiki/Soil_fertility

    Nitrogen and potassium are also needed in substantial amounts. For this reason these three elements are always identified on a commercial fertilizer analysis. For example, a 10-10-15 fertilizer has 10 percent nitrogen, 10 percent available phosphorus (P 2 O 5) and 15 percent water-soluble potassium (K 2 O). Sulfur is the fourth element that may ...

  7. Tillage - Wikipedia

    en.wikipedia.org/wiki/Tillage

    Secondary tillage produces finer soil and sometimes shapes the rows, preparing the seed bed. It also provides weed control throughout the growing season during the maturation of the crop plants, unless such weed control is instead achieved with low-till or no-till methods involving herbicides .

  8. No-till farming - Wikipedia

    en.wikipedia.org/wiki/No-till_farming

    Tillage is the agricultural preparation of soil by mechanical agitation, typically removing weeds established in the previous season. Tilling can create a flat seed bed or one that has formed areas, such as rows or raised beds, to enhance the growth of desired plants. It is an ancient technique with clear evidence of its use since at least 3000 ...

  9. 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 ...
