AbstractIntensive breeding is related to formation of considerable amount of manure which may be used as a natural fertilizer. Manure fertilization may cause reduction of the amount of applied mineral fertilizers and thus reduction of production costs. It may particularly relate to the species with great fertilization requirements such as winter rapeseed. The objective of the research was to compare economic efficiency of rapeseed production in two farms which use different fertilization variants. In one, only mineral fertilizers were used and in the second one – mineral fertilization was supplemented with manure organic fertilization. The use of manure caused reduction of expenditures on materials and raw materials used in production, in particular of fertilizers. At comparable yields obtained by two farms, technology based on manure fertilization proved to be more efficient.

In water treatment applications, the use of ceramic membranes is associated with numerous advantages relative to polymer-based filtration systems. High-temperature stability, fouling resistance, and low maintenance requirements contribute to lower lifecycle costs in such systems. However, the high production costs of most commercially available ceramic membranes, stemming from raw materials and processing, are uneconomical for such systems in most water treatment applications. For this reason, there is a growing demand for new ceramic membranes based on low-cost raw materials and processes. The use of unrefined mineral feedstocks, clays, cement, sands, and ash as the basis for the fabrication of ceramic membranes offers a promising pathway towards the obtainment of effective filtration systems that can be economically implemented in large volumes. The design of effective ceramic filtration membranes based on low-cost raw materials and energy-efficient processes requires a balance of pore structure, mass flow, and robustness, all of which are highly dependent on the composition of materials used, the inclusion of various pore-forming and binding additives, and the thermal treatments to which membranes are subjected. In this review, we present recent developments in materials and processes for the fabrication of low-cost membranes from unrefined raw materials, including clays, zeolites, apatite, waste products, including fly ash and rice husk ash, and cement. We examine multiple aspects of materials design and address the challenges relating to their further development.

Aim of study: To evaluate the use of compost and natural rocks as partial replacement of mineral fertilizers in ‘Flame’ seedless grape vineyards.Area of study: The present work was conducted during three successive seasons (2016, 2017 and 2018), being the first season a preliminary trial on 4-yr old grapes cultivated in two different soil types (sandy and clay) at two different locations, Egypt (Abo Galeb, Giza governorate; EL-Mahala, Gharbia governorate).Material and methods: Treatments were applied as natural raw materials at 20, 40, 60, 80 and 100% out of recommended mineral NPK rate. The mineral fertilizers used were ammonium sulfate (21.6% N), calcium super phosphate (15.5% P2O5) and potassium sulfate (48% K2O). The natural rocks used were phosphate rock (22.0% P2O5) and Feldspar (10.12% K2O). Yield and fruit characteristics and leaf mineral content were determined.Main results: Using compost in combination with natural rocks enriched with NPK mobilization bacteria and mineral NPK enhanced leaf nutrients content and gave the highest yield and cluster weight. This mix also improved berries physical and chemical characteristics. There was an increase in soluble solids content (SSC), SSC/acid ratio, and anthocyanin content, associated with a reduction in nitrate content of the berry juice. The most pronounced effect was related to using 60% mineral fertilization + 40% organic and natural rocks in both vineyard locations.Research highlights: We can reduce the recommended doses of mineral NPK by about 40%, reducing then the soil pollution.

Выход энергии — 43 ГДж/га, энергетический коэффициент (отношение величины выхода продукции к затраченной энергии) — 8,1. Коренное улучшение лугов с применением минеральных удобрений обеспечило получение 0,8 т/га корм. ед. при затратах 4,1 тыс. руб./га, рентабельность составила 56%. Продуктивность естественных угодий при коренном улучшении с использованием органических удобрений — 0,9 т/га корм. ед., рентабельность — 278% при затратах 1,9 тыс. руб./га. Выход энергии с использованием минеральных удобрений — 9,1 ГДж/га, энергетический коэффициент — 1,9, на фоне органических удобрений — соответственно 10,2 ГДж/га и 3,4. Внесение органических удобрений один раз в 5 лет способствовало существенному снижению затрат при коренном улучшении лугов и значительному повышению рентабельности производства. На основании полученных результатов можно заключить: рентабельность производства многолетних трав достаточно высокая, особенно при использовании органических удобрений. Поэтому в хозяйствах с экстенсивными технологиями многолетние травы должны составлять основу кормопроизводства. This article reports on economic and energy efficiencies of perennial grasses cultivated in pastures and haylands. Experiments on hay production took place in the forest-steppe in 2007–2012. Optimization of natural forage lands was conducted in 2011–2016. Alfalfa had the highest hay productivity and economic efficiency under mineral nutrition yielding 3.2 t ha-1 of feed units. Payback amounted to 190%, production costs — 8.8 thousand rubles ha-1. Energy yield reached 43 GJ ha-1, energy coefficient (yield-to-energy ratio) — 8.1. Mineral fertilizers led to the yield of feed units of 0.8 t ha-1, costs of 4.1 thousand rubles ha-1, and profitability of 56%. Under organic fertilization natural forage lands produced 0.9 t ha-1 of feed units, profitability reached 278% while costs — 1.9 thousand rubles ha-1. On the background of mineral nutrition energy yield amounted to 9.1 GJ ha-1, energy coefficient — 1.9, on the background of organic nutrition — 10.2 GJ ha-1 and 3.4, respectively. Organic fertilization once in 5 years significantly reduced costs and increased profitability. Production of perennial crops resulted in high payback, particularly under the application of organic fertilizers. Therefore, farms applying extensive cultivation practices should widely grow perennial grasses.
