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.

In the present study, a considerable build up in soil organic carbon under tree canopy as compared to open canopy was found and soil organic carbon under tree canopy decreased with an increase in soil depth and increasing canopy distance. The total nitrogen percentage in soil decreased with an increase in depth and canopy. In case of available soil phosphorus, it decreased under the tree canopy with increasing soil depth and canopy distance.

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.

A field experiment was conducted during kharif, 2015 at College of Agriculture, V. C. Farm, University of Agricultural Sciences, Bangalore. The experiment comprised of thirteen treatments consisting of three levels of phosphorus (75, 100 and 125% of recommended dose) and various phosphorus biofertilizers and Plant Growth Promoting Rhizosphere (PGPR) and their combinations. The experiment was laid out in RCBD with three replications.

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 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.

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.

A study was carried out to assess the available nutrient status in soils of Kumbhi block under Lakhimpur (Kheri) district (U.P.). In that context 60 soil samples were collected from the different locations of Kumbhi block. Collected soil samples taken for laboratory analysis and analyzed the physico-chemical properties viz. pH, Electrical conductivity, Bulk density, Particle density, Water holding capacity, Organic carbon and status of available nutrients viz. nitrogen, phosphorus, potassium and sulphur.

The present investigation entitled “Fertility status of irrigated soils of Jhotwara panchayat samiti of Jaipur district “was carried out during 2010-11. The soils were pH neutral to alkaline (pH 7.2–8.5) in reaction having electrical conductivity (EC) value in surface soil (0.53–2.51 dSm-1 ). The data on nutrient showed that the soils are low in organic carbon and available nitrogen and low to medium in available phosphorus and available sulphur whereas, medium to high in available potassium.

Soil quality is one of the important factors controlling yields of the crops. Soil characterization in relation to evaluation of fertility status of the soils of an area or region is an important aspect in the context of sustainable agricultural production. Soil physicochemical parameters are more important that control its quality. Variation in nutrient supply is a natural phenomenon and some of them may be sufficient whereas others deficient.

A pot culture study was conducted in 20 acidic soils of Senapati District of Manipur, India during rabi season of 2013-14 to estimate the critical limit of P in soil and pea plant for predicting the response of pea (Pisum sativum L.) to P application as well as to study the effect of P application on dry matter yield and uptake of nutrients in pea crop. The experimental soil was acidic in nature, electrical conductivity of the soil was in safe limit for crop growth. The organic carbon status was almost high and soil was clay in textural class.
