Phosphate rich organic manure is a type of fertilizer used as an alternative to diammonium phosphate and single super phosphate.. Phosphorus is required by all plants but is limited in soil, creating a problem in agriculture In many areas phosphorus must be added to soil for the extensive plant growth that is desired for crop production.
By adding manure to crops it adds nitrogen, potassium, phosphorus, sulfur, magnesium and calcium. [11] While also increasing soil stability by increasing organic material, increasing water infiltration, it can add bacteria diversity and over time reduce the impacts of soil erosion. [11] However, there is organic manure and non-organic manure.
There must be phosphorus in the soil, but the plant must also absorb the phosphorus. Phosphorus uptake is limited by the chemical form of the phosphorus. A large portion of phosphorus in soil is in chemical compounds that plants can't absorb. [9] Phosphorus must be present in soil in specific chemical arrangements to be usable as plant nutrients.
In 2007, a University of Minnesota study [12] [13] indicated that foods such as corn, lettuce, and potatoes have been found to accumulate antibiotics from soils spread with animal manure that contains these drugs. Organic foods may be much more or much less likely to contain antibiotics, depending on their sources and treatment of manure.
Potatoes are root vegetables that grow in soil underground. Even after picking, potatoes almost always carry around some dirt and debris that may have some pesticides or bacteria in the mix.
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 ...
Natural phosphorus-bearing compounds are mostly inaccessible to plants because of the low solubility and mobility in soil. [115] Most phosphorus is very stable in the soil minerals or organic matter of the soil. Even when phosphorus is added in manure or fertilizer it can become fixed in the soil. Therefore, the natural phosphorus cycle is
For example, one medium head of cauliflower contains 129 milligrams of calcium, 88 milligrams of magnesium, 259 milligrams of phosphorus and 1,760 milligrams of potassium - plus zinc, iron, copper ...
