Near infrared reflectance spectroscopy (NIRS) has recently become a potentially valuable and reliable tool for analyses of plant samples in forage-breeding programs. The success of NIRS is dependent on identification of appropriate and reliable selection criteria and development of reliable calibration. The objectives of this study were to develop and compare NIRS analysis equations for the in ...

the aim of the present study was to assess whether near infrared reflectance spectroscopy (nirs) and regression equations are the practical and accurate approach of nutritional assessment of common feedstuffs. therefore two experiments were conducted to study the effect of amino acid determination methods on broiler performance. in experiment i, two hundred thirty four male ross broiler chicks ...

Barley grains contain a variable amount of biologically active compounds such as non-starch polysaccharides and phenol compounds. These are important in nutrition due to their significant health benefits technological role food. We developed predictive models for ?-glucans (BG), arabinoxylans (AX), bound phenols (BP), free (FP), anthocyanins (AN) based on near-infrared spectroscopy (NIRS) using...

Abstrak. Erosi merupakan suatu proses baru atau terkikisnya lapisan tanah akibat adanya energi kinetik hujan yang menyebabkan terdispersinya partikel-partikel tanah. Kondisi ini mengalami erosi akan menjadi miskin kandungan unsur hara dan bahan organiknya. Peristiwa terjadi karena banyak terdapat pada atas (top soil)khususnya N, P K sebagai penyubur tanaman. Untuk mengetahui tidak yakin apa dap...

The near Infrared (NIR) region of the electromagnetic spectrum extends from the upper wavelength end of the visible region at about 770 nm to 2500 nm (13,000 to 4000 cm"). Absorption bands in this region are overtones or combinations of fundamental stretching vibrational bands that occur in the region of 3000 crnvto 1700 cm". The bonds involved are usually C-H, N-H and O_H'·2 Near-Infrared Refl...

This paper describes analysis by near infrared reflectance spectroscopy (NIRS) and demonstrates the capacity of this technology to provide rapid, low cost and accurate estimates of feed composition. The need for an extensive database against which the instruments is calibrated and the importance of good wet chemistry backup to NIRS are emphasised, together with some of the diverse uses for NIRS...

Soil fertilizer management is important to adjust the soil fertility by supplying fertilizers at optimum level to achieve maximum yield at minimum environmental risks. Precision agriculture demands to develop better cost and time efficient methodologies for analysis of soil properties. Besides conventional techniques, sometimes spectroscopy is more accurate, fast, non-destructive and inexpensiv...
