Humans use seaweeds nutritionally as food, industrially for animal feed and plant fertilizer, and ecologically to improve environmental conditions. [ 7 ] [ 6 ] [ 8 ] Seaweeds have been consumed by humans for centuries because they have excellent nutritional profiles, contain minerals, trace elements , amino acids , and vitamins , [ 7 ] and are ...
In plants, soil acidification results in smaller, less durable roots. [27] Acidic soils sometimes damage the root tips reducing further growth. [28] Plant height is impaired and seed germination also decreases. Soil acidification impacts plant health, resulting in reduced cover and lower plant density. Overall, stunted growth is seen in plants ...
Locations that have high rainfall levels become acidic through leaching. Land used for crop and livestock purposes loses minerals over time by crop removal and becomes acidic. [ 5 ] The application of modern chemical fertilizers is a major contributor to soil acid by the process in which the plant nutrients react in the soil.
ions from the root. Some plants also exude organic acids into the soil to acidify the zone around their roots to help solubilize metal nutrients that are insoluble at neutral pH, such as iron (Fe). Fertilizer use: Ammonium (NH + 4) fertilizers react in the soil by the process of nitrification to form nitrate (NO − 3), and in the process ...
Phytic acid, mostly as phytate in the form of phytin (i.e. the calcium/magnesium salts of phytate), is found within the hulls and kernels of seeds, [20] including nuts, grains, and pulses. [1] In-home food preparation techniques may break down the phytic acid in all of these foods. Simply cooking the food will reduce the phytic acid to some degree.
In preparing foods with high phytic acid concentrations, it is recommended they be soaked in after being ground to increase the surface area. [10] Soaking allows the seed to undergo germination which increases the availability of vitamins and nutrient, while reducing phytic acid and protease inhibitors , ultimately increasing the nutritional value.
When PSB is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. [citation needed] The use of PSB as inoculants increases P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg P 2 O 5 /ha or 50 percent of the need for phosphatic fertilizers ...
Fertilizers are materials that can be added to soil or plants, in order to provide nutrients and sustain growth. Typical organic fertilizers include all animal waste including meat processing waste, manure, slurry, and guano; plus plant based fertilizers such as compost; and biosolids. [2] Inorganic "organic fertilizers" include minerals and ash.
