The aim of this work was to analyze the supply of vine by nutrients by determining the content of nitrogen, phosphorus, potassium, calcium and magnesium in the vineyard soil and the vine leaves. Its further goal was to discover mutual relationships among the content of determined nutrients, the vine crop, and the quality of the produced must. Must quality was here defined by the contents of sugar and acids. The final goal was to investigate the relations among the nutrients, vine crop and its quality and meteorological factors measured during the whole year cycle, and especially at the time of important vegetation changes. The necessary evaluations were performed using multidimensional data analysis.

Results of analysis of the consumption of particular macronutrients in natural fertilizers in Poland are discussed in the paper. Analysis included the consumption of nitrogen, phosphorus and potassium in particular types of natural fertilizers, both in relation to the fertilized area and agricultural land. The study period covered the years 2018-2019. The amount of macronutrient resources of natural fertilizers was determined at a voivodship level. As a result of data analysis, it was shown that more than 80% of NPK macronutrients were applied to the soil in the form of manure. In Poland, total NPK consumption in manure was estimated at about 80 kg/ha UAA, including 27.4 kg of N, 17.3 kg of P2O5 and 33.5 kg of K2O. The highest doses of NPK components in natural fertilizers, on a fertilized area, were applied in the Lubuskie, Podlaskie, Lubelskie and Warmińsko-Mazurskie voivodeships, as well as the Wielkopolskie Voivodeship. In none of the voivodeships did the average dose of nitrogen used in manure exceed the permissible level of 170 kg of N/ha. In terms of intensity of macronutrient fertilization from natural fertilizers, the Podlaskie Voivodeship came first, which confirms its importance in terms of animal production and its significance for the development of bioeconomy in Poland.

Abstract We present the VEra Data Analyzer (VEDA) software package for Very Long Baseline Interferometry (VLBI) phase-referencing observations and parallax measurements. The Japanese VLBI project VLBI Exploration of Radio Astrometry (VERA) provides high-precision astrometric results at the 10 μas level. To achieve this precision, accurate calibration of the atmospheric phase fluctuation, the instrumental phase, and the source structural effect is required. VEDA specializes in phase-referencing data analysis, including these calibrations. In order to demonstrate its performance we analyzed H2O maser observations of W 3(OH) and Orion KL with VERA. Their parallaxes were obtained to be 0.527 ± 0.016 mas and 2.459 ± 0.029 mas, respectively. We also analyzed their data using AIPS, which is widely used for VLBI data analysis, and confirmed that the parallaxes obtained using VEDA and AIPS are coincident within 10 μas. VEDA is available for high-precision parallax and proper motion measurements of Galactic maser sources.

Good soil contains sufficient nutrient content for plants. Some of the most important nutrients in the soil include nitrogen, phosphorus, and potassium. However, regosol soil cannot provide enough nutrients and water. The objectives of this study include: 1) comparing the volume of water given with a frequency of 1, 2 or 3 days for NPK nutrient availability on regosol soils; 2) determining the amount of NPK nutrients available after 30 days of incubation by giving different compost doses; 3) determining the interaction between the frequency of water supply and decomposition of organic matter in providing NPK nutrients to regosol soils. This study used a completely randomized design method with a 3 × 3 factorial pattern with 3 replications, therefore there were 27 experimental units. Data analysis of the observed variables was done using variance analysis with SAS program ver 9.0 and if there was a real treatment effect followed by a different test between treatments using BNT (5%). Compost applied to the soil was done, this was indicated by a low C / N value of 14.3 and in accordance with the SNI value standards of 10-20. The results of the study showed that the application of water and organic matter independently has a significant effect on the N content, P, and K in the ground. Whereas, the interaction between the two treatments of water frequency application and organic matter had no significant effect on the levels of N, P, and K in the soil. The conclusion of this study, with the application of water once every 3 days and the treatment of 300g/pot organic matter (B2) was best to provide the highest Ntotal value (0.53%), P available (17, 50 mg/kg), and Kexch (2.03 me/100g). Keywords: compost, frequency of water supply, regosol   ABSTRAK Tanah yang baik memiliki kandungan hara yang cukup bagi tanaman. Beberapa unsur hara yang terpenting dalam tanah antara lain ialah nitrogen, fosfor dan kalium. Tetapi tanah regosol tidak dapat menyediakan unsur hara dan air dengan cukup. Tujuan dari penelitian ini antara lain: 1) membandingkan volume air yang diberikan dengan frekwensi 1, 2 atau 3 hari sekali untuk ketersediaan hara NPK pada tanah regosol; 2) menetapkan banyaknya unsur hara NPK tersedia setelah 30 hari inkubasi dengan pemberian dosis kompos yang berbeda; dan 3) mengetahui interaksi antara frekwensi pemberian air dan dekomposisi bahan organik dalam menyediakan hara NPK pada tanah regosol. Penelitian ini menggunakan metode Rancangan Acak Lengkap dengan pola faktorial 3 × 3 dengan 3 ulangan sehingga terdapat 27 satuan percobaan. Analisis data dari variabel yang diamati menggunakan analisis ragam dengan program SAS ver 9.0 dan jika terdapat pengaruh perlakuan yang nyata dilanjutkan dengan uji beda antar perlakuan menggunakan BNT (5%). Kompos yang diaplikasi ke tanah sudah matang, hal ini ditandai dengan nilai C/N yang rendah yaitu 14,3 dan sesuai dengan standar nilai SNI yaitu 10-20. Hasil penelitian menunjukkan bahwa pemberian air dan bahan organik secara mandiri memberikan pengaruh nyata terhadap kadar N, P, dan K dalam tanah. Sedangkan, interaksi antara kedua perlakuan air dan bahan organik tidak berpengaruh nyata terhadap kadar N, P, dan K dalam tanah. Kesimpulan dari penelitian ini, dengan pemberian air 3 hari sekali dan perlakuan bahan organik 300g/pot (B2) adalah dosis yang lebih baik untuk mendapat nilai Ntotal, Ptersedia dan Kdd tertinggi yaitu N total (0,53%), P tersedia (17,50 mg/kg), dan K dd (2,03 me/100g). Kata kunci: frekwensi pemberian air, kompos, regosol
