Assessment of Nutrient Status in the Cassava Growing Tracts of Southern Laterites (Agro Ecological Unit 8), Kerala, India

As part of the study, a survey was conducted to identify the soil fertility constraints of cassava growing tracts of AEU 8, Thiruvananthapuram, which is one of the major cassava growing regions of the State of Kerala in peninsular India. The method of sampling of the survey was random sampling wherein a random sample of size one was taken from each of 50 ha cassava area. Panchayat wise soil samples were collected (77 samples) by geo referenced soil sampling method from major cassava growing areas of the unit. The samples are analyzed for the soil fertility parameters following standard analytical procedures. Results indicated that the soil was very strongly acidic to strongly acidic, normal electrical conductivity, medium organic carbon, medium nitrogen and potassium, high phosphorus, sufficient calcium, sulphur, zinc and copper, deficient magnesium and boron.

Assessment of nutrient status in Rajagondanahallli Micro-watershed of Channagiri taluk, Davanagere district, Karnataka by using geographic information system technique

The study was conducted to assess the soil fertility status and to prepare the fertility mapping at Rajagondanahallli micro-watershed (480.55 ha) of Davangere district by using GIS and GPS techniques during the year of 2019 to 2021. Total 44 surface soil samples at 320 × 320 m grid intervals (0 to 15 cm depths) were collected and soil fertility mapping were developed by using Arc GIS software. The fertility status of soils of Rajagondanahallli micro-watershed indicated that the soil were low (81.15 %) to medium (9.58 %) in available nitrogen, low (4.77 %) to medium (85.95 %) in available phosphorus, medium (52.10 %) to high (38.63 %) in available potassium, available sulphur were found to be sufficient, whereas exchangeable calcium and magnesium were found to be sufficient. DTPA extractable zinc was sufficient in 434 ha (90.24 %) and deficient in 2 ha (0.49 %) area. Whereas DTPA extractable iron, manganese, copper were sufficient. Available boron was low (20.19 %) to medium (70.53 %) in the study area.

A comparative study on zinc fertilizer brands available in the markets of Jessore region

A study was conducted in Monirampur upazila under Jessore district from July to December, 2016 to collect information on names, numbers and comparative availability of different brands of Zinc fertilizers in order to aid the assessment of nutrient status for quality of the brands. For this purpose, information was collected from 54 randomly selected fertilizer shops (20 BCIC fertilizer dealers and 34 retailers) through questionnaire interview. In the study total 77 brands [41 Zinc sulfate (mono), 11 Zinc sulfate (hepta) and 25 Chelated zinc] of zinc fertilizer marketed by 49 companies were found in the upazila. Zingsul, Mim zinc, Grogin, Bumper mono zinc, Eon zinc and Geel mono of Zinc sulfate (mono) brands, Topaz of Zinc sulfate (hepta) brands and Mim zinc gold of Chelated zinc brands were mostly available. “Grogin” of Zinc sulfate (mono) and “Topaz” of Zinc sulfate (hepta) were the top most available. Ten percent of Zinc sulfate (hepta) mentioned no registration number. There was a significant difference between highest and lowest MRP of all types (imported, supplied and manufactured) of Zinc sulfate (mono) and Zinc sulfate (hepta) fertilizer as well as imported Chelated zinc brands.Int.

Assessment of Nutrient Status in Athletes and the Need for Supplementation.

Nutrition assessment is a necessary first step in advising athletes on dietary strategies that include dietary supplementation, and in evaluating the effectiveness of supplementation regimens. Although dietary assessment is the cornerstone component of the nutrition assessment process, it should be performed within the context of a complete assessment that includes collection/evaluation of anthropometric, biochemical, clinical, and environmental data. Collection of dietary intake data can be challenging, with the potential for significant error of validity and reliability, which include inherent errors of the collection methodology, coding of data by dietitians, estimation of nutrient composition using nutrient food tables and/or dietary software programs, and expression of data relative to reference standards including eating guidance systems, macronutrient guidelines for athletes, and recommended dietary allowances. Limitations in methodologies used to complete anthropometric assessment and biochemical analysis also exist, as reference norms for the athlete are not well established and practical and reliable biomarkers are not available for all nutrients. A clinical assessment collected from history information and the nutrition-focused physical exam may help identify overt nutrient deficiencies but may be unremarkable in the well-trained athlete. Assessment of potential food-drug interactions and environmental components further helps make appropriate dietary and supplement recommendations. Overall, the assessment process can help the athlete understand that supplement intake cannot make up for poor food choices and an inadequate diet, while a healthy diet helps ensure maximal benefit from supplementation. Establishment of reference norms specifically for well-trained athletes for the nutrition assessment process is a future research priority.

Uses of Stable Isotopes in the Assessment of Nutrient Status and Metabolism

Stable isotopes are nonradioactive and can be safely administered to humans; yet, because of the isotopic difference, can be distinguished from the unlabeled moiety and thus trace the nutrient uptake and elimination. Stable isotope applications include measurement of nutrient absorption, determination of nutrient body stores, tracing routes of nutrient metabolism, measuring nutrient fluxes through specific pathways, and measuring nutrient elimination. The ability to assess the dynamics of nutrient metabolism in vivo has been vital in the study of nutrient requirements, nutrient metabolism, mechanisms of nutrient homeostasis, and nutrient toxicity. Stable isotopes provide a window into human metabolism that is particularly valuable to the quantitative study of human nutrition.
