Aim: To analyze and map the soil micronutrient status in the transition zone of NW foothills of Shivaliks of Kathua Region using GIS. Methodology: Composite surface soil samples from two hundred and six (206) locations distributed randomly due to undulated topography across the whole of the district were collected at the depth of 0-15 cms using global positioning system (GPS). Inverse distance weighting (IDW) technique was adopted to generate prediction maps of the soil properties. The process of digitization and generation of maps was carried out with ArcGIS 10.3. Results: After soil sample analysis, the available copper content in the soil of hilly areas varies from 0.4 to 14.4 mg kg-1 with a mean value of 3.75 mg kg-1. Available Zinc content ranged from 0.25 to 5.60 mg/kg respectively. The available Manganese content of the surface soils varied between 5.60 to 78.10 mg kg-1 with a mean value of 23.97 mg kg-1. Available Iron content ranged from 11.30 to 92.00 mg/kg with a mean value of 38.57 mg kg-1. The available copper content in the soil of plain areas varies from 2.08 to 34.90 mg kg-1 with a mean value of 8.94 mg kg-1. The minimum and maximum values of available copper content lies in higher range. Available Zinc content ranged from 0.25 to 5.60 mg kg-1 respectively. According to the map, available zinc is visualized lowest in plains due to raised soil pH. The available manganese content of the surface soils varied between 2.500 to 57.40 mg/kg with a mean value of 27.03 mg kg-1. Available Iron content ranged from 0 to 66.10 mg kg-1 with a mean value of 41.68 mg kg-1. Conclusion: The mapping was done successfully with micronutrients varying from low to high range. The technique was found to be effective in identifying the micronutrients availability throughout the study region, thereby helping policy makers to frame fertilizer distribution and application policy for future.

SUMMARYThis paper reports a continuation of previous work on the mineral constituents of ewe's milk, in particular copper, iron, manganese and zinc. Milk taken at weekly intervals from four groups of Clun Forest and Suffolk x Clun Forest ewes was studied over lactations varying from 6 to 12 weeks. The copper content showed a marked decline as the lactation advanced, while there was no consistent trend in iron content. Maximum, minimum and mean values for iron and copper are given for the sheep in each group.Manganese was determined in the milk from two groups and zinc in. that from one group of ewes. There were significant differences in weekly manganese content in both groups, but no consistent trend as lactation advanced. Zinc content showed no significant differences from week to week, but the milk of one ewe was consistently very much lower in zinc than that of the other five sheep.

Quantitative assessment of ecological vulnerability is of great significance for ecological protection and restoration in ecologically vulnerable regions. Here, the ecological vulnerability of the northern sand prevention belt (NSPB) of China was assessed using an ecological pressure–sensibility–resilience model from 2000 to 2015. Results showed that the ecological vulnerability index (EVI) displayed low values in the eastern part and high values in the western part of the study region. The EVI ranged from 0.29 to 1.32 in 2000, with the mean value of 0.88, whereas it averaged 0.78 in 2015, ranging from 0.21 to 1.26. Decreasing EVI from 2000 to 2015 indicated that the ecological status has been improved. Moreover, the area proportion of moderately, heavily, and extremely ecological vulnerability levels occupied approximately 87% in both 2000 and 2015, indicating a high ecological vulnerability level. Furthermore, the change in area proportion of different ecological vulnerability levels were associated with the change in the spatial distribution of vegetation coverage, indicating that eco-environmental protection projects were indeed effective. These findings indicated that differential strategies in different restoration zones should be adopted, especially in the western parts of the study region, and eco-environmental protection projects should be reinforced to improve the ecological restoration.

Ca -DTPA or Zn -DTPA was injected subcutaneously to pregnant mice once a day for 5 consecutive days from the 13th day to the 17th day of gestation. Maternal and fetal livers were collected 20 hours after the final injection of DTPA, and essential metal contents in the liver samples were determined by PIXE. Both Ca -DTPA and Zn -DTPA don't affect any essential metals in the maternal liver, but Ca -DTPA decreases copper and zinc contents in the fetal liver to 2/3 and 1/2 of the control values, respectively. Although Zn -DTPA does not affect fetal zinc content, it decreases that of copper. It could not be determined whether DTPA affects fetal manganese content or not because the fetal liver contains no detectable amount of manganese.

ABSTRACTNutrient Enhancement In Cereal Crops Using Actinobacterial EndophytesWheat high demand without sufficient production and Actinobacterial endophytes usage limitation inIndonesia motivated this research. The aim was to determine Actinobacterial endophytes effect on nutrientenhancement in wheat (Triticum aestivum L.). It was hypothesized that they can enhance wheat nutrient.The experiment stages were: 1) Pot-Trial I, confirming nutrient enhancement using Actinobacteria in 6 soiltypes; 2) Pot-Trial II, screening Actinobacteria strains; and 3) Field-Trial. The results showed thatActinobacteria effects varied for different nutrients and site based differences. In Pot-Trial I, different soiltypes significantly affected the manganese and zinc content (P=0.00 and P=0.01), but not inoculation ofActinobacteria nor the combination of them. Field Trials showed the same trends. Combination betweenthose treatments significantly affected manganese content (P=0.045). Nutrient analysis on xylem sap in PotTrials 2 only showed the value differences since there was insufficient collected volume to be statisticallyanalyzed. Zinc and iron contents were the highest in Actinobacteria EUM165 treatment and the highestmanganese content in Actinobacteria EN16. In conclusion, wheat nutrient content is affected byActinobacteria and different soil types but there was insufficient evidence to generally conclude that it canbe enhanced. They have their own effects and affected each other in enhancing nutrient content.Keywords: Nutreint, wheat, endophytic ActinobacteriaABSTRAKTingginya permintaan gandum tidak disertai produksi yang cukup, serta terbatasnya pemanfaatanActinobacteria endofit di Indonesia, melatarbelakangi penelitian ini.

Tahapan penelitianmeliputi: 1) Uji-Pot I, mengonfirmasi peningkatan nutrisi gandum menggunakan Actinobacteria pada 6 jenistanah; 2) Uji-Pot II, menguji berbagai strain Actinobacteria terhadap peningkatan nutrisi gandum; serta 3)Uji Lapangan. Hasilnya menunjukkan bahwa Actinobacteria meningkatkan nutrisi gandum secara berbedatergantung nutrisi yang diuji serta jenis tanah yang digunakan. Pada Uji-Pot I, jenis tanah berpengaruhnyata terhadap kandungan mangan dan seng (P=0.00 dan P=0.01), tapi pemberian Actinobacteria maupunkombinasi keduanya tidak. Uji Lapangan menunjukkan hasil yang sama. Kombinasi kedua perlakuanmeningkatkan kandungan mangan secara signifikan (P=0.045). Analisis cairan xilem dari Uji-Pot IImenunjukkan perbedaan hasil tanpa uji statistik karena terbatasnya cairan yang dikumpulkan. Kandungantertinggi seng dan zat besi ditunjukkan oleh perlakuan Actinobacteria EUM165 dan mangan yang lebihtinggi oleh Actinobacteria EN16. Disimpulkan bahwa kandungan nutrisi tanaman gandum dapatdipengaruhi oleh pemberian Actinobacteria endofit serta perbedaan jenis tanah, namun tidak cukup buktiuntuk menyimpulkannya secara umum. Baik jenis tanah maupun Actinobacteria endofit memiliki pengaruhsendiri serta saling mempengaruhi terhadap kandungan nutrisi tanaman gandum.Kata kunci: Nutrisi, gandum, actinobacteria endofit

Important biogenic elements of plants are zinc and copper, which come into them from the soil in the form of cations. Plants selectively absorb the elements they need in accordance with physiological and biochemical needs, as well as the characteristics of their vegetation. Copper and zinc are part of the enzymes that are necessary for the normal course of many biochemical reactions. Lack or excess of any chemical element causes a violation of the normal course of biochemical and physiological processes in plants. The paper presents the results of the study of zinc and copper content in the soil, as well as in the above-ground and underground organs of the studied plant object. Quantitative determination of zinc and copper was carried out on an atomic absorption spectrometer. As an object of study, a flower plant of the Gentian family (lat. Gentianáceae), genus Eustoma (lat. Eustoma), grade Aube Pink Picotee. Vegetation experiments were carried out on the basis of LLC "Greenhouse "Iceberg". According to the data, the content of zinc and copper in the organs of the studied plant decreases in a number of root – aboveground part – flower. In different periods of vegetation there is a different accumulation of copper and zinc in the aboveground and underground organs. The root of this plant performs a barrier function, blocking the flow of copper into the plant from the soil at 27 weeks of development. In this case, the zinc content in the root of the plant during this period increases significantly, but this figure in the above-ground part of the plant varies slightly. According to the calculated average value of the biological absorption coefficient, it can be seen that the accumulation of zinc in the plant occurs to a greater extent than the accumulation of copper.

Rice is one of the most important staple food crops for billions of people throughout the world. It is the cheapest source of dietary energy, protein and minerals for people but poor in micronutrients such as Fe and Zn to eliminate “hidden hunger”. In the present study, a population of 126recombinant inbred lines developed from a cross between Lemont X Satabdi (IET 4786) were used to identify high iron and zinc content coupled with yield and yield attributing traits. Analysis of Variance revealed that a considerable variation in iron and zinc existed among genotypes. The correlation study revealed that number of filled grain was positively associated with panicle length and yield per plant and number of panicles, but no significant positive correlation was observed between grain zinc content and iron content. Zinc and iron content of rice was estimated using Atomic Absorption Spectrophotometer and the samples were prepared by tri-acid digestion method. Among RIL lines, the line 57, 97,120, 48, 99, 124 contained more than 30 ppm Fe and the lines 24, 6, 9, 23, 29, 125 were found to possess more than 50 ppm Zn. The lines 9,6,48 and 57 were recorded to be high yielding with high zinc and Fe content in grain and in future these four lines look promising for multi location trial also. These high Fe and Zn content genotypes can be utilized in future breeding programme as a donor or good source for bio fortification of rice genotypes.

For 30 days five healthy men aged 23-57 yr consumed a diet adequate in zinc (8.6 mg/day); they ate a low-zinc diet (3.6 mg/day) for the next 120 days and then received a zinc-supplemented (33.6 mg/day) diet for 30 days. Copper intake was constant at 1.8 mg/day. Aerobic capacity was determined periodically during each diet period. Relative zinc balance (% of control) declined during depletion (r = -0.28, P less than 0.009). Pre- and postexercise zinc concentrations decreased when dietary zinc was restricted (r = -0.61, P less than 0.0001 and r = -0.78, P less than 0.0001) and increased with supplementation (r = 0.61, P less than 0.008 and r = 0.76, P less than 0.0003, respectively). Both plasma zinc and hematocrit increased (P less than 0.01) after maximal exercise. To minimize the effect of hemoconcentration during exercise, the van Beaumont quotient (J. Appl. Physiol. 34: 102-106, 1973) was calculated using pre- and postexercise hematocrit and plasma zinc. The initial quotient of 1.8 +/- 1.8% (mean +/- SE) declined (P less than 0.05) to -7.4 +/- 2.3% during depletion. With zinc repletion, the quotient increased to 6.9 +/- 3.6%, which was greater (P less than 0.05) than the quotient in depletion but similar to the initial quotient. The quotient was a strong predictor (r = 0.71, P less than 0.0005) of the change in relative zinc balance during zinc depletion. In contrast, no changes were found in plasma copper content. These data suggest that zinc mobilization from tissues is impaired during zinc depletion, and they validate the use of the van Beaumont quotient as an index of change in body zinc stores.
