• pH 7 – This indicates that the soil is neutral and has a balanced pH level. • pH below 7 – This signifies that the soil has a high concentration of acidity. • pH above 7 – This shows that the soil has a high level of alkaline. However, you should also take into consideration that not all plants have the same pH requirement. Some greens are accustomed to different levels of acidity.
Production of organic acids results in the lowering of pH in the surroundings and many reports suggests a positive correlation between lowering of pH and mineral phosphate solubilization. Some of the alternate mechanisms suggested are production of chelating compounds, inorganic acids like sulphuric, nitric and carbonic acids. Another attractive application of P-dissolving enzymes is the mineralization of soil organic P compounds through phytate degradation mediated by the enzyme phytase, which specifically causes release of P from phytic acid. Phytate is a major component of organic P in soil. There are several reports of phytase producing organism.
Macro-organisms found in the soil: If a lot of worms or other organisms are found in the soil, it will indicate that the soil is most probably healthy enough for the access of people as it is not to acidic or alkaline to contain life because Earthworms need moisture and nutrients. Water
%Pasreceived is 5.8±0.008% and %Pdry 12.7±0.008 and %P2O5asreceived 6.63±0.008 and %P2O5dry 14.48±0.008. This shows that there are also other components present in the fertilizer sample that is Introduction The agricultural value of fertilizer samples depend on their total phosphate and water content. Natural phosphates are found in small amounts in all better types of soil and their presence is very important for plant growth. Phosphate content was determined as a precipitate magnesium ammonium phosphate hexahydrate.  Moisture determination is an important indicator of the fertilizer 's quality.
An improved crop yield by inoculation with a phosphate solubilizing fungal strain has been observed in many field studies. Thus, during the present investigation the facts that the inoculation of PSF has a positive effect on the growth and productivity of plants, has led us to in vitro and pot experiment studies to observe the ability of Aspergillus niger K7 in the growth, yield and nutrient absorption of plants against the soil
The organic agriculture techniques are known as ecological sustainable by • Improving soil structure and fertility through the use of crop rotations, organic manure, mulches and the use of fodder legumes for adding nitrogen to the soil fertility cycle. • Prevention of soil erosion and compaction by protecting the soil planting mixed and relay crops. •
However, the lower layer was identified to be unoxidized (grey) glacial clay till of the Floral Formation. The Battleford till was found to have lower shear strength than the Floral till. In some areas, the two till layers are directly connected, in other areas are separated by layer comprised of sand and gravel or sandy silty clay with variable thickness. Both the glacial clay till and the clay lacustrine soil deposits are a part of a distinct geological unit known as the Saskatoon
The pocket penetrometer is intended as a lightweight tool for use in the field to examine visual classification of soils. It indicates compressive strength, consistency and penetration resistance. However, the readings attained do not replace test results from a laboratory since a insignificant area of penetration test might give misleading results. (Gerald F. Gifford, Robert H. Faust, George B. Coltharp, 1977) Soil becomes compacted as soil particles are forced to pack more closely together. Mainly through mechanical compression, and this leads to a decrease or total elimination of air pores.
Since riparian areas are low areas in a landscape, groundwater is usually nearer to the surface leaving the soil rich in organic matter. With the soil being rich it give off enough nutrients making the soil healthy for plant growth. Riparian zones are known to be nutrient rich ecosystems because of their water flow. Riparian areas can help the community and many ways as well. They may help control nonpoint source pollution by holding and using nutrients and reducing
