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.

A screen house experiment was conducted during rabi season of 2018-19 to find out the effect of different levels of P and Zn on wheat yield, concentration of different nutrients in grain and straw in low and high P status soil. Five levels of P (0, 30, 60, 120 and 180 mg P kg-1 soil) and four levels of Zn (0, 2.5, 5 and 10 mg Zn kg-1 soil) were applied in completely randomized design with three replications.

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.

Nine typical pedons from Langate Block of Kupwara district during 2017 were selected and surveyed for the purpose of collection of soil samples. The soil samples processed and analyzed for different nutrients. Available Micro and Macro nutrients were determined using standard techniques. The overall results showed that the soils are near slightly acidic to moderate alkaline in reaction, low to medium in organic carbon. In general the soils The available nutrients Nitrogen and Potassium were low to medium with the mean values of 287.99 and 149.

Banana is a highly exhaustive crop which requires large quantities of mineral nutrients for rapid growth and development, thus it readily responds to applied nutrients. Major nutrients like nitrogen, phosphorus and potassium play an important role in the vegetative and reproductive phases of crop growth, depending on the cultivar.

The present study revealed that pH of pear orchard soils increased with decrease in altitude while as organic carbon decreased with decrease in altitude. The textural class of soils ranged between clay loam to silt clay loam with normal electrical conductivity. The available nitrogen status was low to medium, whereas, available phosphorus status was medium to high and available potassium status was high.

The field investigation entitled “Effect of plant geometry and fertilizer levels on yield and economicsof cowpea (Vignaunguiculata L. Walp)” was conducted at Department of Agronomy, College of Agriculture, Latur. The experimental field was levelled and well drained. The soil was clay loam in texture, low in available nitrogen, very low in available phosphorus, very high in available potassium and moderately alkaline in reaction. The environmental conditions prevailed during experimental period was favourable for normal growth and maturity of cowpea crop.

The major uses of soybean are as a source of edible oil and protein rich food, as well as cattle feed. The nutrient requirement and interaction of different nutrients under high phosphorus conditions were not worked out so far in soybean track. To improve the productivity levels of soybean it is imperative to assess the nitrogen and phosphorus requirement under high P fertility soils to obtain the potential yield by the farmers.

In response to phosphate starvation, plants have to improve their root systems for efficiently acquired phosphate. In Vietnam, rice is one of the most important agricultural crops in which 60% of the rain-fed lowland rice is cultured on soil types, which are low in phosphorus or phosphate fixing. This fact along with the scenario in which phosphate resources are running out in fast pace, highly provoked an indispensible need for developing new rice varieties with high productivity under low phosphate condition.

KVK, Chandgothi, Churu (Rajasthan) conducted total 50 Front Line Demonstrations on cowpea at farmers field in Churu District (Rajasthan) during two consecutive kharif seasons from 2014 to 2015. The farming situation was rainfed and soil was sandy loam low in nitrogen, medium in phosphorus and medium to high in potash. Assessment of gap was done and on the basis of gap assessment, improved recommended technologies were demonstrated.

A field experiment was carried out during kharif, 2016 at the farm of ICAR-Krishi Vigyan Kendra (KVK), Mangaluru, Karnataka state to study the effect of neem cake urea mixed application on growth and yield of rice under submerged condition. The soil of the experimental field was lateritic with acidic pH, medium in available nitrogen, high in phosphorus and low in potassium content. The experiment was laid out in randomized block design with seven treatments and each one replicated thrice.

Study was conducted to evaluate soil fertility status in the four different tasar growing regions in Banka District of Bihar and Dumka District of Jharkhand. A total of 75 surface soil samples (0-30 cm) were collected from the fields of primary tasar food plants (Terminalia arjuna and T. tomentosa) along with the details regarding farmer’s name, land type, fertilizer details, geo location, etc. The collected samples were air dried, sieved and analyzed for various soil fertility parameters such as pH, EC, organic carbon, macro and micro nutrients etc.

Phosphorus is a major limiting factor for plant growth particularly in the tropics and subtropics areas. It play an important role in many biochemical process viz., energy storage and transfer, cell division, cell enlargement and several other processes in plants. The availability of P to plants is a problem owing to its slow diffusion and high fixation in soils. Due to low solubility and mobility in soil, phosphorus use efficiency is very low ranges from 10-20% in normal soil.
