A soil resource inventory was conducted at village level in the Melur block of Madurai district, Tamil Nadu to assess the micronutrients status in the soils and to prepare fertility maps depicting the extent of soil micronutrient deficiency/sufficiency using GIS and GPS techniques. Soil samples were collected at revenue village wise along with geo coordinates and analysed for available micronutrients such as Zn, Fe, Cu and Mn by adopting standard procedures. Based on the nutrient status, the soils were grouped as deficient or sufficient using the critical limits. Per cent deficiency of micronutrients in Melur block was worked out and the thematic maps showing status of different available micronutrients were generated. The results indicated that, Fe and Zn  deficiency is most prevalent in the soils of Melur block  in Madurai district to an extent of more than 35 per cent, followed by Cu (1.1%) and Mn (10%).

This study was conducted to explore the ability of Pseudomonas fluorescens and Bacillus cereus to solubilizing a phosphate in soil for enhancing the planting growth and, its relation with soill characterization. The isolates were identified as P.fluorescens and B. cereus using convential analysis and, its phosphate solubilization ability and sidrophore was shown by the clear zone formation on National Botanical Research Institute���s Phosphate medium. Moreover, Pseudomonas fluorescens isolates (n = 9) and three of B. cereus isolated from agricultural area in Baghdad university, Mustansiriyah university and Diyala bridge. Results displayed that bacterial count were varied in soil samples according to their region, and ranging from 30 to 60 *10 2 CFU/g in Baghdad university soil to 10���20 *10 2 CFU/g in Mustansiriyah university soil, the Baghdad soil macronutrient which included: NH4, NO3, P, and K were, 8.42, 20.53, 19.09, 218.73 respectively, While the physio analysis revealed that the mean of pH was 7.3 and EC was 8.63. on the other hand the micronutrient analysis indicated that the soil samples were included Ca, Fe, Mn, Zn and Cu which gave their mean 5025.9, 8.9, 4.9, 0.5 and 1.5 respectevily. Results revealed that all isolated bacteria (9 isolates of P.fluorescens and three isolates of B. cereus gave ahalo zone which mean their ability to be phosphate solubilizing bacteria at 100%. Results revealed that all isolated bacteria were detected a ability to produce high levels from chelating agents (siderophores)) by P.fluorescens and. B cereus at 100%, when appeared ahalo clear zone. Furthermore, the high levels of phosphate solubilization and siderophore production were grouped in bacterial species isolated from Iraqi soils. might be attributed to many soil factors such as soil nutrient status, soil acidity, water content, organic matter and soil enzyme activities.

Even though soil degradation challenges sustainable development, the use of degradation indicators such as nutrient export (NE) and nutrient replacement cost is not well documented at landform level. This study is aimed to investigate the extent of soil degradation, NE rates, and their replacement cost across landforms in the Mai-Negus catchment, northern Ethiopia. Different erosion-status sites (aggrading, stable, and eroded) in the landforms were identified, and soil samples were randomly collected and analysed. Nutrient export, replacement cost, and soil degradation were calculated following standard procedures. This study showed that soil degradation in the eroded sites ranged from 30 to 80% compared to the corresponding stable site soils, but the highest was recorded in the mountainous and central ridge landforms. Average NE of 95, 68, 9.1, 3.2, 2.5, and 0.07 kg ha−1 y−1 for soil calcium, carbon, nitrogen, potassium, magnesium, and phosphorus, respectively, was found from the landforms. Significantly strong relationships between NE and sediment yield in the landforms were observed. Annual nutrient replacement costs varied among the landforms though the highest was in the reservoir (€9204 in May 2010). This study thus suggests that while introducing antierosion measures, priority should be given to erosion sources to the reservoir such as mountainous and central ridge landforms.

Among the basic needs of life, food possesses ahead of everyone else as it nourishes us and able to stand which leads further activity. Tamil Nadu state is self-sufficient in food production and Nutrient availability assessment also shows the same but the consumption pattern shows inverse pattern to availability because consumption is directly related with income, education, taste and preference, cultural, ethical and etc. Food consumption patterns of rural Tamil Nadu shows that high demand of Public Distribution System (PDS) observed in earlier and gradually decreased over year. Vitamin Thiamine is coming under severe inequality category in rural areas of Tamil Nadu for both 61st and 68 rounds. Goal programming was effectively optimised the nutrient requirement with least cost and optimised to higher level of nutrient status.

Micronutrient deficiency can be considered as one of the yield "quantity and quality" limiting factor in arid calcareous lands and can be considered as the troubling component of hunger. Therefore, enriching food products through adding nutrients to a food product or through increasing soil fertility and breeding crop for nutrient efficiency are alternatives available to improve food quality. However, poor people have no excess to food additives and can benefit from naturally enriched food products or what being called Biofortification. The existence of a general geographical overlap between soil Zn deficiency and human Zn deficiency has been already postulated. As agriculture-based food products are the major source of human nutrition, the relationship between the nutrient status of soils, food crops, and human health is understandable. poor but also deliver all the essential nutrients needed for adequate nutritional health. Sustainable solutions to malnutrition will only be found by closely linking agriculture to nutrition and health. The undergoing review would discuss these concepts and their implementation and uses with special concern on Iraqi conditions.

The role of trace elements (TEs) and their imbalance in the physiology of bone tissue and in the development of inflammatory diseases of the joints and spine has been discussed in recent years; however, there is no evidence for the TE status of patients with ankylosing spondylitis (AS) and its possible impact on the course of the disease.Objective: to investigate the impact of the TE status of patients with AS on the course, clinical manifestations, and activity of the disease.Patients and methods. Examinations were made in 58 patients (39 men and 19 women), residents of the Orenburg Region, with a reliable diagnosis of AS, the duration of which was 16 [11; 26] years. The patients’ mean age was 38 [31; 48] years. HLA-B27 antigen was detected in 91.4% of cases. In addition to the generally accepted examination, atomic absorption spectrophotometry was used to determine the hair levels of 9 TEs: Cu, Zn, Fe, Mn, Cr, Co, Ni, Pb, and Cd in all the patients.Results and discussion. The AS patients living in the Orenburg Region showed TE imbalance manifested by Cu and Zn deficiency and Ni, Cr, and Mn accumulation in the hair. Multidirectional correlations were found between the values of these TEs and the presence of extra-axial (peripheral arthritis, dactylitis) and extra-skeletal (uveitis) manifestations of AS, its activity, and severity of functional disorders.Conclusion. The preliminary results may suggest that the emerging imbalance of TEs can affect the course of AS, maintaining and increasing its activity.

The recommendations of Phosphorus (P) and Potassium (K) fertilization for rice are still not site-specific yet due to a lack of required soil data information.  The P and K status of the paddy fields that provide information on the low, medium, and high P and K nutrient status are very useful for determining recommended the site-specific fertilizer in the the district area. The purpose of the research was to determine the site-specific fertilizer recommendation for paddy field based on their P and K status. This research was based on the field survey and the soil analysis in the laboratory. The soil samples were taken using a grid system, and the P and K levels were assessed by using a 25% HCl extraction. Soil samples were taken in a composite manner on all paddy fields in which their status have been identified. The composite soil samples were determined from 10 - 15 individual samples (sub-samples) with a sampling distance of each sub-sample of 25-50 m in the field.  The soil samples were taken in the overlay with a depth of 0-20 cm. Taking sub-samples were done by a diagonal or a zigzag method according to the conditions of paddy fields. The results of the study presented that the nutrient status of P and K and the fertilizer recommendations in paddy fields for rice plants located in 9 sub-districts in Mempawah Dsitrict had shown that nutrient status of P, on average, were from moderate to high levels, meanwhile, the nutrient status of K was from low to high levels. Recommendations for fertilizing rice fields in several sub-districts in Mempawah Regency are mostly 150 kg NPK (15:15:15) ha-1, 200 kg Urea ha-1 and 25 kg KCl ha-1.

An investigation was undertaken in Tommaladahalli (566.13 ha) micro-watershed of Tarikere taluk, Chikkamagaluru district of Karnataka to assess available nutrient status in the surface soils. About 118 surface soil samples were collected grid wise by using cadastral map at 250 m grid interval and were analyzed for their fertility status using standard procedures. Soil fertility maps were prepared by means of interpolation method called Krigging. The results revealed that the pH, electrical conductivity, and organic carbon were ranged from 5.37 to 9.06, 0.065 to 0.466 dS m-1 and 0.33 to 1.62 per cent respectively. The available N, P2O5, K2O were ranged from 175.6 to 545.6 kg ha-1, 11.8 to 61.1 kg ha-1 and 122.7 to 491.4 kg ha-1, respectively. The available nitrogen and phosphorus were low to medium, where as potassium content was medium to high in the entire study area. Micronutrients viz. zinc, iron and boron were sufficient and were ranged from 0.34 to 1.17 mg kg-1, 2.03 to 21.86 mg kg-1 and 0.30 to 0.89 mg kg-1 respectively.
