The major role of Zinc in biological systems is, maintaining structural and functional integrity of biological membranes, protein synthesis and gene expression. Nearly half of the soils where cereals are grown have levels of available Zinc low enough to cause Zinc deficiency (Alloway, 2009).

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.

A field experiment was conducted at Raipur, during kharif season of 2013 in factorial randomized block design with four replications to assess the effect of planting geometry on grain yield, zinc concentration, zinc yield and soil available zinc content of high zinc rice. Treatment comprised of three planting geometry viz., 10cm x 10cm, 15cm x 10cm and 20cm x 10cm and three levels of nutrient viz., 50%, 100% and 150% recommended dose of fertilizers (RDF).

The soils of Chittoor district was found to be suffering from one or other or combination of two or more micronutrients in 324 out of analysed 576 samples and constituted 56 per cent (Zn alone in 103, Fe in 40, B in 60, Mn in 5, Cu in 5 and multi micronutrient deficiencies in 107 samples). Among individual nutrients, the soils of Chittoor were found to be deficient in available zinc to an extent of 33 per cent and boron in 21% samples.

Interaction between soil microbes and minerals play a major role in environmental cycling processes, which leads to the mobilization of nutrients from soil components into available forms for biological uptake which enhances crop growth and yield. In the present study four (4) potassium solubilizing bacteria (KSB), eight (8) zinc solubilizing bacteria (ZnSB) and two (2) zinc solubilizing fungi (ZnSF) isolated from Rice, Maize, Cotton and Sorghum rhizosphere soil collected from Student and College farm Rajendranagar PJTSAU Hyderabad.

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).

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.

The abiotic stresses, such as soil salinity and sodicity are largely responsible for the low productivity of crops mainly due to low availability of micro-nutrients especially as zinc (Zn) and iron (Fe). Therefore, judicious management of plant nutrients in these soils is as important as their reclamation.

Three hundred soil samples from ten blocks of Jajpur district, Odisha state were studied for distribution of DTPA extractable. Zn, Cu, Fe and Mn and Boron their relationship with some soil properties. Soil pH, calcium carbonate, organic carbon and particle-size fractions had strong influence on the distribution of these micronutrients. The content of micronutrient increased with the increase in organic carbon and decreased with increase in pH. As per critical limit prescribed for Zn 26 per cent and Boran 73.3 percent of the soil could be rated as deficient in available zinc and boron.

Zinc deficiency not only affects crop yields, but also nutritional quality and human health. Microbial transformation of unavailable forms of soil zinc to plant available zinc is an important approach contributing to plant zinc nutrition. Therefore, Nutrient uptake and biological activity in Tomato crop by zinc solubilizing bacterial isolates was tested under glass house condition. The study consisted of six treatments, each with five replications, including five different zinc solubilizing bacteria and uninoculated control, out of five bacteria B. aryabhattai was used as reference strain.

Twenty soil samples were collected from various paddy fields of Imphal west district, Manipur to evaluate status and forms of zinc in the soils. All the soil samples were acidic in nature with mean value of pH 5.52. The mean electrical conductivity was 0.09 dSm-1 and the mean organic carbon content was 10.82 g kg-1 . The mean cation exchange capacity, available nitrogen, available phosphorus and available potassium were 18.0 [cmol (p+ ) kg-1 ], 303.98 kg ha-1 , 28.68 kg ha-1 and 231.06 kg ha-1 , respectively. The mean value of DTPA extractable zinc was 0.91 mg kg-1 .

Twenty eight (28) soil samples from different polyhouses were collected from precision farming development Centre (PFDC) Leh, situated in the cold arid Ladakh region and were analyzed for different soil properties and its fertility status. It is apparent from the study that the majority of soils are rich in organic carbon, available nitrogen, phosphorus, potassium and sulphur and low in available zinc. Among soil properties, organic carbon content had a positive correlation on the availability of nutrients.

The Present study was carried out at Bharatpur district of Eastern Rajasthan during Kharif 2014. Brinjal is one of the most important vegetable crops of the country. The development of the Agriculture is primarily depends on the application of the scientific technologies by making the best use of available resources. One of the major constraints of traditional brinjal farming is low productivity because of non-adoption of advanced technologies like micronutrients. There was deficiency of zinc in most of the soils of the area.

Present study was conducted out during 2015-2016 in Rewa district of Fiji to evaluate available micronutrient (Fe, Cu, Mn and Zn) status and their relationship with the soil properties. Fifty seven sites were selected for soil sampling. The available micronutrient (DTPA extractable) viz., Fe, Mn, Cu and Zn were analyzed using atomic absorption spectrophotometer.

Field experiments were conducted during Kharif season 2015-16 at twenty farmer’s field to refine the critical limit of Zinc in soils for rice crop grown in Mandla district of Madhya Pradesh. The soils of study sites varied in available Zn from 0.12 to 2.17 mg kg-1 and classified in three groups i.e., deficient (0.60 to 1.2 mg Zn kg-1 ). The soils were clayey, neutral to slight alkaline in reaction and low in organic carbon.
