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.

This article deals with comparison of composts and manure use from the viewpoint of handling, transport and application on agricultural land. The published values were established by measurements under working conditions and afterwards converted on the basis of the content of nutrients defined in laboratory. Compost contained a greater share of nitrogen, phosphorus and potassium and had higher dry matter content and lower volume weight. Direct consumed energy expressed by recalculation of the consumed diesel fuel in case of composts moved from 5.12 MJ/kg (potassium) up to 16.19 MJ/kg (phosphorus). In case of manure it was higher and moved from 10.49 MJ/kg (nitrogen) up to 29.79 MJ/kg (phosphorus). The greatest share in energy consumption occupies transport, which was considered uniformly at the distance of 5 km. The study confirmed the feasibility of use of compost in agriculture as a partial substitute of conventional organic fertilizers; for its handling, transport and application the standard mechanization used for manure may be utilized.

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

Soil degradation poses a threat to sub-Saharan sustainability of agriculture namely because of chemical and physical degradation. The objective of this study was to characterise soil properties in oil palm plantation in the districts of Ouémé and Plateau and develop spatial maps for soil nutrients useful in agricultural land use as a basis for designing soil fertility management strategies. A survey carried out in oil palm (Elaeis guineensis Jacq.) plantations in the southern Benin, revealed mineral deficiency symptoms consequent to poor mineral nutrition of the plant. A total of 428 soil composite samples were collected under farmers’ adult oil palm trees, randomly selected. These oil palm plantations were located on four soil types: Acrisol, Plintics and luvisols, Hydromorphic soil and Vertisols. In total, 370 samples were collected on plantations under Acrisols, 22 samples under Plintics and luvisols, 26 samples under Hydromorphic soil and 10 samples under Vertisols. Geostatistic methods were used to determine the spatial variability; and semi-variogram methods were established using ordinary kriging. A strong spatial dependency for nitrogen, phosphorus, potassium and magnesium was observed; while spatial dependency of calcium was moderated. The map of nutrient deficiency revealed two large areas. The first, included the districts of Bonou, Adjohoun, Sakété, Adja-Ouèrè, and Pobè, where oil palm plants showed an acute nitrogen, phosphorus and potassium deficiency; and the second area of Dangbo, Missérété, Ifangni, Avrankou, Adjarra which presented nitrogen, potassium and slight phosphorus deficiency in the oil palm plantations. Most of the soils under the oil palm plantations showed nitrogen, phosphorus and potassium deficiency.

AbstractThe experimental plots used in the study were located in the middle forest zone (elevation: 900-950 m a.s.l.) on two nappes of the flysch Carpathians in southern Poland. The aim of this study was to assess the effects of serpentinite in combination with nitrogen, phosphorus, and potassium fertilizers on selected chemical properties of the soil and activity of dehydrogenase and urease in the studied soils. All fertilizer treatments significantly enriched the tested soils in magnesium. The use of serpentinite as a fertilizer reduced the molar ratio of exchangeable calcium to magnesium, which facilitated the uptake of magnesium by tree roots due to competition between calcium and magnesium. After one year of fertilization on the Wisła experimental plot, the pH of the Ofh horizon increased, while the pH of the mineral horizons significantly decreased. Enrichment of serpentinite with nitrogen, phosphorus, and potassium fertilizers stimulated the dehydrogenase activity in the studied organic horizon. The lack of a negative effect of the serpentinite fertilizer on enzyme activity in the spruce stand soil showed that the concentrations of the heavy metals added to the soil were not high enough to be toxic and indicated the feasibility of using this fertilizer in forestry.

AbstractThe response of native plants to allelopathic interference of invasive species may differ from species to species. In this study, the phytotoxic effects of Ageratina adenophora were tested on two native shrubs (Osbeckia stellata and Elsholtzia blanda) of Nepal. Both the shrubs were grown in pots under treatments of A. adenophora fresh leaves and root leachates, and litter. Then, the seedling length and biomass were compared among the treatments. The results show that A. adenophora litter has stimulatory effects but the leachates from fresh leaves and root are phytotoxic to the growth and development of native shrubs. Infrared Spectroscopy (IR) analysis confirmed the presence of O–H (Hydroxyl), N–H (Amines), C≡C (Alkynes), and C–H stretching (Aromatic) or C–O–C stretching (Ethers) in the leachates representing harmful allelochemicals. The invaded soil by A. adenophora had low pH and a high amount of organic matter, total nitrogen, phosphorus, and potassium than the uninvaded soil. The results indicate that the native O. stellata and E. blanda are harmed by A. adenophora in nature by leaching of allelochemicals and probably by reducing the soil pH. Overall, this study has provided valuable insights regarding the effects of A. adenophora invasion on native shrubs and revealing the potential mechanism of its invasiveness.
