Tea and hazelnut cultivated soils are mainly distributed in Black Sea region of Turkey. Low pH value is a primary problem for those soils; therefore, farmers apply lime once every 3–4 years to raise the pH value of soil. Gyttja is highly rich in organic matter (40.59%) and lime (45.67%), and it is a low cost and considerably abundant in Afşin-Elbistan Coal Basin (estimated reserve is around 4.8 billion tons). The aim of this study was to determine the phosphorus (P) sorption characteristics of gyttja, and its efficiency on P availability and soil’s pH value.

White lupin (Lupinus albus) is a leguminous crop with elite adaptive ability in phosphorus-deficient soil and used as a model plant for studying phosphorus (P) use. However, the genetic basis of its adaptation to low P (LP) remains unclear. ATPase binding cassette (ABC) transports G subfamily play a crucial role in the transportation of biological molecules across the membrane. To date, identification of this subfamily has been analyzed in some plants, but no systematic analysis of these transporters in phosphorus acquisition is available for white lupin.

Acquisition of external phosphorus (P) and optimisation of internal P are essential for plant growth and development, and insufficient availability of P in soils is a major challenge in agriculture. Members of the purple acid phosphatase (PAP) family of enzymes are candidates for increasing P use efficiency.

Phosphorus (P) is one of the major essential macronutrients for biological growth and metabolism of plants. Tea (Camellia sinensis L) plantation requires adequate amount of P for the proper yield of tea leaves. However, due to acidic nature of tea growing soils, phosphorus fixation is a common phenomenon. A close look at the different pools of soil P reveals, major portion of soil P is present in the form of organic P.

In acidic soils of Nagaland, the levels of available soil N, P and K together with organic carbon content and soil pH could be considered main soil fertility determinants. With a vision to come up with a best performing treatment that can be recommended for practice in the farmer’s field and to popularize the importance of forest litter in achieving sustainability, the present investigation has been undertaken to evaluate the effect of forest litter and its time of incorporation on soil fertility status.

The soil available N, P and K were significantly higher in treatment supplemented with application of 100 per cent RDF through soluble fertilizers by fertigation over 100 per cent RDF through conventional fertilizers. Yield was significantly maximum in application of 100 per cent RDF through soluble fertilizers by fertigation than other treatments.

Phosphorus (P) deficiency is second to nitrogen (N) and its deficiency is widespread. Soil based site specific P recommendation for sustainable crop productivity mainly relies on status, and availability of phosphorus. Representative soil samples (250) from different agro-ecological regions of Eastern Dry Zone (EDZ) of Karnataka were analysed for P status and randomly collected samples were analysed for P fractions.

Investigation indicates that valuable effects of biochar could be obtained if it was applied with mycorrhiza. Combined application of biochar (10 t ha-1 soil), phosphorus along with mycorrhiza produced significantly higher uptake of nutrients in baby corn. Biochars are highly variable in nutrient composition and availability, which are determined by types of feedstock and pyrolysis conditions. The results suggest that high-ash biochars with phosphorus are potential P sources with high-agronomic efficiency.

A field experiment was conducted during kharif 2016 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P.). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 6.7), low in organic carbon (0.35%), available N (230 kg ha-1 ), available P (20 kg ha-1 ) and available K (189 kg ha-1 ).

The field experiment was conducted at College of Agriculture, Shivamogga during kharif 2015-2016. The total quantity of P and plant-available P often differ greatly fraction in acidic soils. Assessing available P is fundamental aspect to managing P in many of these soils. The objectives of this study were to effect of phosphorus levels through integrated nutrient management (INM) packages on status of phosphorus in soil under groundnut crop.

The use of lime instead of Gypsum can provide not only Ca for the ground crop but also improves the availability of other plant nutrients. Proper incorporation of lime into the soil ensures the availability of Ca in the podding zone (Cox et al., 1982).

An investigation was carried out to study the distribution of available macronutrients (N, P, K and S) and their relationship with some physico-chemical properties of soil of different blocks of district Udham Singh Nagar (Uttarakhand).The soils of the district were found sufficient in Phosphorus, Potassium and Sulphur but low in available Nitrogen content. In general the macronutrients were correlated significantly and negatively with pH and positively with organic carbon of the soil.

Field experiments were conducted during 2010-12 at Regional Research Station, Virudhachalam to find out the residual effect of fly ash, farm yard manure and fertilizers applied to groundnut on growth parameters, nutrient uptake, yield of sesame and post-harvest soil available nutrients. The Neyveli Lignite Corporation fly ash contained higher amount of Ca, Mg, S and Si, moderate amount of P, K and B. Application of fly ash @ 40 t/ha significantly increased growth parameters, yield attributes, seed yield and harvest index of sesame.

These symbiotic microorganisms have extensive mycelial network and can increase the transport of other mineral elements such as zinc and copper. VAM fungi can play an important role in enhancing P availability to plants in deficient soils and can save P-fertilizer by 25-30% (Somani et al., 1990).

Universal extractant is a term used to designate reagents or procedures to extract several elements or ions to assess soil fertility status or levels of toxicity. The extraction procedure should be rapid, reproducible, inexpensive, adaptable to soils from different regions, and extract the labile forms of nutrients which might be potentially available to plants. Most of the extractants in use are fall short of these requirements.
