  2. Cattle feeding - Wikipedia

    en.wikipedia.org/wiki/Cattle_feeding

    Grain-fed cattle have more internal fat (i.e., marbling) which results in a more tender meat than forage-fed cattle of a similar age. In some Asian countries such as Japan , which is not a grain-surplus country, tastes and preferences have encouraged feeding grain to cattle, but at a high cost since the grain must be imported.

  3. Soil acidification - Wikipedia

    en.wikipedia.org/wiki/Soil_acidification

    Basic cations like calcium are leached from the soil as acidic rainfall flows, which allows aluminum and proton levels to increase. [3] [4] Nitric and sulfuric acids in acid rain and snow can have different effects on the acidification of forest soils, particularly seasonally in regions where a snow pack may accumulate during the winter. [5]

  4. Soil pH - Wikipedia

    en.wikipedia.org/wiki/Soil_pH

    Global variation in soil pH. Red = acidic soil. Yellow = neutral soil. Blue = alkaline soil. Black = no data. Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics.

  5. Polyface Farm - Wikipedia

    en.wikipedia.org/wiki/Polyface_Farm

    Animal manure fertilizes the pastures and enables Polyface Farm to graze about four times as many cattle as on a conventional farm, thus also saving feed costs. [3] The small size of the pastures forces the cattle to "mob stock", or to eat all the grass. [4] Polyface raises cattle, pastured meat chickens, egg layers, pigs, turkeys, and rabbits.

  6. USDA soil taxonomy - Wikipedia

    en.wikipedia.org/wiki/USDA_soil_taxonomy

    The soil moisture regime, often reflective of climatic factors, is a major determinant of the productivity of terrestrial ecosystems, including agricultural systems. The soil moisture regimes are defined based on the levels of the groundwater table and the amounts of soil water available to plants during a given year in a particular region.

  7. Acid sulfate soil - Wikipedia

    en.wikipedia.org/wiki/Acid_sulfate_soil

    The term ‘acid sulfate soils’ (ASS) was coined by the Working Party on Nomenclature and Methods for the first International Symposium on Acid Sulfate Soils (1972, Wageningen) to mean soils that contain, or have the potential to produce, sulfuric acid in quantities that cause significant and long-lasting changes in key soil properties. [22]

  8. Fodder - Wikipedia

    en.wikipedia.org/wiki/Fodder

    In many cases the production of grass for cattle fodder is a valuable intercrop between crops for human consumption, because it builds the organic matter in the soil. [ citation needed ] When evaluating if this soil organic matter increase mitigates climate change, both permanency of the added organic matter as well as emissions produced during ...

  9. Feedlot - Wikipedia

    en.wikipedia.org/wiki/Feedlot

    Cattle in feedlots are fed grain rather than more natural forage. This is designed to make them gain weight faster, but it leads to internal abscesses and discomfort. [ 19 ] Grain-based diets can also lead to the growth of harmful bacteria such as Clostridium perfringens and E. coli . [ 20 ]
