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.
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 ...
For instance, sheep manure is high in nitrogen and potash, while pig manure is relatively low in both. Horses mainly eat grass and a few weeds, so horse manure can contain grass and weed seeds, because horses do not digest seeds as cattle do. Cattle manure is a good source of nitrogen as well as organic carbon. [3]
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.
Glyphosate adsorption to soil, and later release from soil, varies depending on the kind of soil. [ 96 ] [ 97 ] Glyphosate is generally less persistent in water than in soil, with 12- to 60-day persistence observed in Canadian ponds, although persistence of over a year has been recorded in the sediments of American ponds.

Soil Microbial community composition and functionality is largely driven by underlying soil health and abiotic properties. [ 69 ] [ 70 ] Many DNA sequencing and omics -based approaches, combined with greenhouse experiments, have been used to characterize microbial responses to seaweed fertilizer treatment on a wide variety of crops.
Harvesters gather the green manure crops and mix the plant material into the soil. The un-decomposed plants prepare the ground for cash crops by slowly releasing nutrients like nitrogen into the soil. [3] Farmers may decide to add the green manure into the soil before or after cash crop planting.
C. pubescens is a tropical forage, so it requires very low phosphorus, but it responds to phosphate fertilization. Leaves should be a minimum of 0.16% phosphorus at flower formation. [7] The ideal available P in the soil for a good yield is between 2–5 mg of phosphorus per kg of soil and 12.4 mg per kg of soil of potash. [12]
