High P status soil

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.

The field study was carried out during kharif 2009-10 and 2010-11. The fertility status of the soil was moderate in organic carbon, low in available N and P and very high in available K while the soil micronutrient contents (Zn, Fe, Mn, Cu) were above the critical level.

The study was conducted to know the soil fertility status of different cropping systems in hill zone acid soils of Karnataka. In each cropping systems, samples were collected from two depths (0-15 cm and 15-30 cm) at 20 locations randomly. Soil characterization revealed that soils were slightly acidic to moderately acidic in range with low soluble salts. Surface soils under paddy cropping system recorded higher exchangeable Al3+ and exchangeable acidity compared to coffee and areca cropping system.

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.

Positive responses to Zn addition on numerous crops have been documented. In this study, we field tested no Zn (0 kg ZnSO4.7 H2O/acre) and Zn treatment (25 kg ZnSO4.7 H2O/acre) in zinc deficient sites and their effect on grain yield of Pusa Basmati 1121. Surface soil samples (0-15cm) were collected from 16 sites from basmati rice grown soils in Gurdaspur district of Punjab. Findings of the study revealed that soils had variable available phosphorus and zinc status. The grain yield ranged from 20.8 to 29.8 q/ha in control with mean value of 25.

Two hundred fifty soil samples from Tatrakallu village in scarce rainfall zone of Andhra Pradesh were drawn at 250 m grid interval leaving hills and water bodies and assessed for their fertility parameters. Analytical data was interpreted and statistical parameters like range, mean, standard deviation and coefficient of variation were calculated. Soil fertility maps were prepared for each parameter under GIS environment using Arc GIS v 10.3. Soils were neutral to strongly alkaline with non-saline in nature and soil organic carbon content was low to medium.

The present study was undertaken to assess the status of available Zinc in relation to soil physico-chemical properties in nineteen soil samples collected from three different blocks of Birbhum district of West Bengal. In general, textural class ranged from sandy loam to sandy clay loam. Soils were strong to moderately acidic in reaction. Soil organic carbon status ranged from 0.24 to 0.81% and was low in available P status. The DTPA-extractable zinc content in the surface soils under study, varied from 0.37 to 1.28 mg kg-1 with an average value 0.856 mg kg-1 .

Greenhouse experiment was conducted to assess the soil biochemical change patterns in soils of arbuscular mycorrhizal fungus (AMF)-inoculated and uninoculated maize plants fertilized with varying levels of P and Zn. Soil samples were collected for mycorrhizal spores, microbial communities, available micronutrients and phosphorus (P) contents besides organic and biomass carbon (BMC), soil enzymes and glomalin. Major portion of Fe and Zn fractionations was found to occur in the residual form.
