And Control

Tetracyclines, sulphonamides, and quinolones are families of antimicrobials (AMs) widely used in the poultry industry and can excrete up to 90% of AMs administrated, which accumulate in poultry litter. Worryingly, poultry litter is widely used as an agriculture fertilizer, contributing to the spread AMs residues in the environment. The aim of this research was to develop a method that could simultaneously identify and quantify three AMs families in poultry litter by high-performance liquid chromatography–tandem mass spectrometry (HPLC–MS/MS). Samples of AMs free poultry litter were used to validate the method according to 657/2002/EC and VICH GL49. Results indicate that limit of detection (LOD) ranged from 8.95 to 20.86 μg kg−1, while limits of quantitation (LOQ) values were between 26.85 and 62.58 µg kg−1 of tetracycline, 4-epi-tetracycline, oxytetracycline, 4-epi-oxytetracycline, enrofloxacin, ciprofloxacin, flumequine, sulfachloropyridazine, and sulfadiazine. Recoveries obtained ranged from 93 to 108%. The analysis of field samples obtained from seven commercial poultry flocks confirmed the adequacy of the method since it detected means concentrations ranging from 20 to 10,364 μg kg−1. This provides us an accurate and reliable tool to monitor AMs residues in poultry litter and control its use as agricultural fertilizer.

The Impact

A survey was conducted to assess the impact of mobile applications developed by theKrishiVigyan Kendra Banavasi with 150 farmers in Kurnool district of Andhra Pradesh inthe year 2020. KVK Banavasi developed three mobile applications namely ANGRAU-ATARI CFLD, ANGRAU Pashu Poshan and Fertilizer Calculator for benefiting farmingcommunity. Majority (64.67%) of the respondents were found in medium usage of mobileapplications, in agriculture. Fertilizer Calculator mobile application was found highest usage(74.50%) among the farmers when compared with other two applications. ANGRAUATATRI CFLD application was used by an average of 46.83 per cent farmers forinformation on new improved varieties, 75 % for control measures of pest and diseasesand 29 per cent for market related information. ANGRAU Pashu Poshan application wasused by 75 per cent livestock farmers for sheep management, 56 per cent for cattlemanagement and 45 per cent for poultry related information. Fertilizer calculator applicationwas used by 80 per cent farmers for recommended dose of fertilizers and 10 per cent forsoil test based fertilizer application.

Main Factor

For usage of glass fertilizer, physical and dissolution properties were investigated according to variation of the SiO2 and K2O contents in silicate glasses. In glass forming region, K2O/P2O5 0-0.24, SiO2/(SiO2+P2O5) 0-0.29 and CaO/P2O5 0-1.00 were fabricated as clear glass in K2O-CaO-SiO2-P2O5 glass system. The glass transition temperature (Tg) and softening temperature (Ts) were gradually shifted to the higher temperature range according to increase of SiO2 contents. The K2O contents, which could cause the structure change from network structure to polymeric chain structure, have direct proportion with the thermal expansion coefficient and inverse proportion with Tg and Ts. The change of the K2O/P2O5 ratio was a main factor to control chemical durability and physical properties such as density and hardness. In the abnormal glass properties such as fast dissolution in aqueous solution, it was presented that the glass can be a good candidate for agriculture fertilizer.

Despite increased attention to the need for sustainable agriculture, fertilizer application rates above crop requirements remain common agricultural practices in South Korea, causing eutrophication of freshwater and coastal ecosystems. The aim of this study is to quantify phosphorus (P) inputs, outputs, and retention in a forested-agricultural watershed. The P budget showed that the combined use of chemical fertilizer and organic compost was the largest source of P (97.6% of the total) followed by atmospheric wet deposition (2.1% of the total P), whereas forest export (0.2% of the total) and sewage treatment plants (STPs) (0.1% of the total) were negligible. The P outputs were crop harvesting and hydrologic export to surface water. The P balance showed that P inputs are higher than the P outputs; approximately 87% of the total P input was retained in the soils within the watershed. However, P concentrations in drainage water were still high enough to cause eutrophication of downstream reservoirs. The results provide important details on the proportion of P export and retention in the watershed. This will help efforts to improve water quality and design better management strategies for agricultural nonpoint source pollution.

Sepiolite is a naturally occurring clay mineral of sedimentary origin and is a magnesium hydrosilicate. Sepiolite has been widely used as an additive raw material in ceramics and cement industry, pharmaceutical, cleaning-detergent, paper, paint, cosmetic agriculture, fertilizer, etc. In this study, the natural radioactivity levels, radon emanation coefficients and radon exhalation rates of 30 sepiolite samples collected from open three sepiolite quarries (Beylikova, Polath and Sivrihisar) in Central Anatolia region of Turkey were determined by using a gamma-ray spectrometry with an HPGe detector. The average absorbed gamma dose rates directly measured in Beylikova, Polath and Sivrihisar open three sepiolite quarries located in Central Anatolia region of Turkey were found as 59, 65, and 64 nGyh?1, respectively. The average activity concentrations of 226Ra, 232Th, and 40K in 30 sepiolite samples collected from those quarries were found as 38.6, 12.4, and 67.4 Bqkg?1, respectively. The average emanation coefficient and exhalation rate of radon of sepiolite samples were determined as 22 % and 0.065 Bqkg?1h?1, respectively. Also, radiological parameters (outdoor absorbed gamma dose rate, annual effective dose rate, external and internal index) were estimated to evaluate the use of sepiolite samples as additive raw materials in the building sector.

Agricultural Input

The data of Nepal Government shows that nine major pesticides groups with seven subgroups of Insecticides were imported from the year 1997 to 2003. The pesticide use amounts to 142 g/ha which is low compared to other counties. The highest pesticides quantity imported & quantity consumed from the 2056/57 (1999) to 2060/061(2003) were fungicides, bactericides, acaricides & seed treatment. group. For the year 2056/57 (1999) & 2057/58(2000), no import & consumption of biopesticides were done but from the year 2058/59(2001) to 2060/061(2003) no import & consumption of plant regulators was done. The various types of pesticides with 306 trade names and 71 technical names are registered / enlisted and used in Nepal which includes Insecticides, Fungicides, Herbicides, Rodenticides, Acaricides and Others. Moreover, twelve types of pesticides are band in Nepal for its import and use. Similarly, the demand of fertilizers were increased from 1997/98 to 2001/02 and then decreased dramatically with high amount from 2001/02 to 2002/03 and since then again it again increased up to 204/05. This trend is same for Urea and Diammonium Phoshphate whereas Murate of Potash is increasing from 1997/98 to 2004/04. Seven types of fertilizers are being used in Nepal viz. Urea, Diammonium Phosphate (DAP), Murate of Potash (MOP), Ammonium Sulphate (AS), Single Super Phosphate (SSP), Ammonium Phosphate Sulphate (APS) and NPK. These are imported by Public institution like Agricultural Input Corporation (AIC) , Private Institutions and also donated/granted by the Government of Japan called as 2KR (Two Kenny Round). The import of fertilizers shows irregular trend. The import of fertilizers was highest in 1998/99 which amounted to 219038 metric ton and since then it decreased although there showed fluctuations. The distribution of fertilizers was increase from 1997/98 and reached highest in the year 2002/03 and since then it started decreasing. Similarly, the fertilizer consumption was highest in the year 1994/95 which was 30.4kg/ha which declined since then and showed fluctuation. The fertilizer consumption is regularly decreasing in the recent years from the year 2002/03.
