  2. Foliar feeding - Wikipedia

    en.wikipedia.org/wiki/Foliar_feeding

    Foliar application has been shown to avoid the problem of leaching-out in soils and prompts a quick reaction in the plant. Foliar application of phosphorus, zinc and iron brings the greatest benefit in comparison with addition to soil where phosphorus becomes fixed in a form inaccessible to the plant [5] and where zinc and iron are less available.

  3. CO2 fertilization effect - Wikipedia

    en.wikipedia.org/wiki/CO2_fertilization_effect

    Declines in magnesium, calcium, potassium, iron, zinc and other minerals in crops can worsen the quality of human nutrition. Researchers report that the CO 2 levels expected in the second half of the 21st century will likely reduce the levels of zinc, iron, and protein in wheat, rice, peas, and soybeans. Some two billion people live in ...

    en.wikipedia.org/wiki/Plant_nutrition

    Foliar sprays are used on fruit crop trees in soils of high alkalinity. [citation needed] Selenium is, however, an essential mineral element for animal (including human) nutrition and selenium deficiencies are known to occur when food or animal feed is grown on selenium-deficient soils. The use of inorganic selenium fertilizers can increase ...

    en.wikipedia.org/wiki/Soybean_management_practices

    Soy beans crops in Minnesota. Soybean management practices in farming are the decisions a producer must make in order to raise a soybean crop. The type of tillage, plant population, row spacing, and planting date are four major management decisions that soybean farmers must consider. How individual producers choose to handle each management ...

  6. Seaweed fertiliser - Wikipedia

    en.wikipedia.org/wiki/Seaweed_fertiliser

    Foliar applications of seaweed fertilizer extract have been shown to improve the uptake of nitrogen, phosphorus, potassium, and sulfur in soybeans such as Glycine max. [59] Research has also demonstrated that brown algae seaweed extracts can improve tomato plant growth, overall crop yield, and resistance to environmental stressors. [60]

  7. Soybean - Wikipedia

    en.wikipedia.org/wiki/Soybean

    Soybeans contain significant amounts of phytic acid, dietary minerals and B vitamins. Soy vegetable oil, used in food and industrial applications, is another product of processing the soybean crop. Soybean is a common protein source in feed for farm animals that in turn yield animal protein for human consumption. [4]

  8. Fertilizer - Wikipedia

    en.wikipedia.org/wiki/Fertilizer

    Urea is highly soluble in water and is therefore also very suitable for use in fertilizer solutions (in combination with ammonium nitrate: UAN), e.g., in 'foliar feed' fertilizers. For fertilizer use, granules are preferred over prills because of their narrower particle size distribution, which is an advantage for mechanical application.

  9. Soybean meal - Wikipedia

    en.wikipedia.org/wiki/Soybean_meal

    Globally, about 98 percent of soybean meal is used as animal feed. [9] Of the US soybean production magnitude from 2010 through 2012, about 44 percent was exported as soybeans, and 53 percent was crushed in the US. Of the crushed tonnage, 19 percent was recovered as soybean oil and the remainder was recovered as soybean meal. Of the total US ...
