Combined Application

Few studies have focused on the combined application of digestate and straw and its feasibility in rice production. Therefore, we conducted a two-year field experiment, including six treatments: without nutrients and straw (Control), digestate (D), digestate + fertilizer (DF), digestate + straw (DS), digestate + fertilizer + straw (DFS) and conventional fertilizer + straw (CS), to clarify the responses of rice growth and paddy soil nutrients to different straw and fertilizer combinations. Our results showed that digestate and straw combined application (i.e., treatment DFS) increased rice yield by 2.71 t ha−1 compared with the Control, and digestate combined with straw addition could distribute more nitrogen (N) to rice grains. Our results also showed that the straw decomposition rate at 0 cm depth under DS was 5% to 102% higher than that under CS. Activities of catalase, urease, sucrase and phosphatase at maturity under DS were all higher than that under both Control and CS. In addition, soil organic matter (SOM) and total nitrogen (TN) under DS and DFS were 20~26% and 11~12% higher than that under B and DF respectively, suggesting straw addition could benefit paddy soil quality. Moreover, coupling straw and digestate would contribute to decrease the N content in soil surface water. Overall, our results demonstrated that digestate and straw combined application could maintain rice production and have potential positive paddy environmental effects.

The short-term effects of processed waste materials: sewage sludge compost (up to 0.5%), biochar made of paper sludge and grain husk (BC) (up to 2%) combined with plant growth-promoting rhizobacterial (PGPR) inoculum, on the fertility of acidic sandy soil at 65% of field capacity were tested in a pot experiment in separate and combined treatments. The soil pH, organic matter content, total and plant-available nutrients, substrate-induced respiration, arbuscular mycorrhizal fungal (AMF) root colonisation parameters and maize (Zea mays L.) biomass were investigated in experiments lasting two months. The positive priming (21% organic matter loss) induced by BC alone was not observed after combined application. The combination of compost and PGPR with 1.5% BC resulted in 35% higher P and K availability due to greater microbial activity compared to BC alone. Only compost applied alone at 0.5% gave a 2.7 times increase in maize biomass. The highest microbial activity and lowest AMF colonisation were found in combined treatments. In the short term the combined application of BC, compost and PGPR did not result in higher fertility on the investigated soil. Further research is needed with a wider range of combined treatments on acidic sandy soil for better understanding of the process.

Растительные отходы сельскохозяйственного производства в основном утилизируются в качестве кормов в животноводстве и реже используются в виде удобрения на многолетних насаждениях. Из растительных сельскохозяйственных отходов в качестве органического удобрения могут быть использованы вторичные отходы винодельческого производства, виноградные выжимки. Обоснование возможности применения такого вида биоудобрения в конкретных условиях с учетом показателей, характеризующих биоматериал и состав почвы, послужило целью выполненной работы. Биогенность деградируемой почвы ампелоценозов увеличивается легко гидролизируемыми виноградными выжимами, по своему биохимическому составу являющимися зональным экологическим индукторам физико-химического и механического состава почвы. Партии используемого биоматериала, вносимого в почву опытных участков в период проводимых исследований, по своим биохимическим показателям (азот, фосфор, калий, органическое вещество, рН) не имели существенных различий. Показатели содержания подвижных форм фосфора и калия в почве используют для оценки фосфатного и калийного режимов разных почв. При их недостаточности в почве рациональна замена агрохимикатов, относящимся к средствам химизации сельского хозяйства (фосфор-калийные удобрения), биоудобрением из отходов виноградовинодельческого производства, содержащим эти макроэлементы. Определено, что повышение биогенности и физико-химического состава почвы возможно обогащением ее отходами виноделия, содержащими питательные вещества для корнеобитаемого слоя почвы (азот 6,3%; фосфор 0,44%; калий 1,59%), органическое вещество до 82% и рН не вызывающий изменений кислотного баланса почвы. Установлено, что после одного цикла (весна-осень-весна 2017-2018 гг.) внесения биоудобрения в комплексе с эффективными микроорганизмами (препарат Байкал ЭМ-1) почва характеризовалась увеличением органического вещества на 0,3%, подвижных форм фосфора - на 11,0 мг/кг, общего азота - на 0,07%, макроэлементов кальция, натрия, магния, калия - от 2,0 до 7,0 мг/кг, уменьшением гранулометрического состава почвы (фракция < 0,01 мм) - на 0,7%, снижением концентрации тяжелых металлов (кобальт, мышьяк, медь, цинк - по ГОСТ) - от 0,1 до 6,0 мг/кг. Использование виноградных выжимок в комплексе с эффективными микроорганизмами в качестве энергетического биоматериала удовлетворяет современным требованиям эколого-экономической и эффективной утилизации растительных отходов сельского хозяйства в области виноградовинодельческого производства.Vegetation residue from agricultural production is mainly used as feed in livestock rearing, and is less frequently used as fertilizer on perennial plantings. From agricultural green waste, secondary waste from wine production and grape pomace can also be used as organic fertilizers. We conducted feasibility studies on the use of such bio-fertilizers under specific conditions, taking into account soil composition and biomaterial parameters. Biogenesity of the degrading soils of ampelocenoses can be improved by easily hydrolyzed grape marc, the biochemical composition of which serves as zonal ecological inducer of soil physico-chemical and mechanical composition. Batches of biomaterial introduced into soil of experimental plots during research had no significant differences in biochemical parameters (nitrogen, phosphorus, potassium, organic matter, pH). Active forms of phosphorus and potassium content in the soil is used to estimate the phosphate and potassium statuses of different soils. When their content in the soil is insufficient, it is recommended to replace the agrochemicals (phosphorus-potassium fertilizers) with bio-fertilizers from grape-growing production waste rich in those macronutrients. The study established that soil biogenisity and physico-chemical composition can be improved through its enrichment with winemaking waste containing nutrients for soil root layer (nitrogen 4.3 %; phosphorus 0.49%; potassium 1.49%), up to 82% of organic matter and the pH that does not alter the soil acid balance. It was found that one cycle (spring-autumn - spring 2017-2018) of bio-fertilizer introduction combined with effective microorganisms (Baikal EM-1 preparation), increased organic matter in the soil by 0.3 %, active phosphorus by 11.0 mg/kg, total nitrogen by 0.07%, calcium, sodium, magnesium, and potassium macronutrients from 2.0 up to 7.0 mg/kg, and decreased soil granulometric composition (fraction < 0.01 mm) by 0.7 %; it decreased heavy metal concentration (cobalt, arsenic, copper, zinc - under GOST) from 0.1 to 6.0 mg/kg. Combined application of grape pomace and effective micro-organisms as energy biomaterial meets modern requirements for environmentally sound, effective and efficient disposal of agricultural green waste material in the field of viticulture.

Combined Application

Efficiency of an organic matter like Tagetes erecta and bioinoculants Azotobacter chroococcum and Glomus fasciculatum was investigated in tomato cultivar ‘Pusa Ruby’ when inoculated individually as well as concomitantly for the management of the root-knot nematode, Meloidogyne incognita in terms of growth parameters such as plant length, fresh and dry weights, chlorophyll content, per cent pollen fertility and mycorrhization. Greatest reduction in the numbers of second-stage juveniles in soil, number of root-galls, egg-masses and nematode multiplication was recorded with combined application of T. erecta and bio-inoculants A. chroococcum and G. fasciculatum as compared to untreated control and other treatments. Similarly, the greatest improvement in the plant growth and biomass of tomato was noted in the same treatments. However, individual inoculation of these bio-inoculants and organic fertilizers also showed significant enhancement but was less as compared to combined treatment. A. chroococcum was found most effective against disease incidence followed by G. fasciculatum and T. erecta. Parameters like NP and K contents were significantly enhanced in those plants which received combined treatments of organic matter and bio-inoculants. Azotobacter was found more efficacious against nematodes than Glomus fasciculatum. Organic matter also influenced the activity of bio-inoculants, more with the Azotobacter than G. fasciculatum.

Abstract The paper presents a study on the microbiological activity and the quality of organic matter of a Haplic Luvisol soil amended with selected organic and mineral materials (manure, clay, flotation lime, aluminium and iron oxides and a bark-keratin-urea preparation), during a three-year field experiment. In the soil under analysis (pH in 1M KCl pHKCl - 4.46, organic carbon Corg. - 0.465%) the following parameters of microbiological activity were assayed: numbers of microorganisms, activity of dehydrogenases, and respiration. In addition, the quality of organic matter was analysed through the determination of its susceptibility to chemical (biological) oxidation (oxidable carbon and non oxidable carbon). The components applied to the soil had a varied effect on the studied parameters of microbiological activity during the whole period of the study. The application of manure and clay caused an increase in the numbers of bacteria, in the activity of dehydrogenases, and in the intensity of the process of soil respiration. Soil respiration was stimulated also by the application of manure and clay in combination with Fe2O3 at the dose of 6 kg. Moreover, a decrease in the number of bacteria in the soil was noted after the combined application of manure, clay and Fe2O3 6 kg. The materials applied in the study caused a variation in the susceptibility of organic matter of Haplic Luvisol soil to oxidation. Soils amended with manure and clay in combination with calcium, aluminium, iron, were characterised by limited susceptibility to organic matter oxidation, while the bark-keratin-urea preparation applied caused a considerable improvement of that susceptibility

Area Of Interest

There is little known of the basic parameters of the Lower Silurian graptolitic black shales that are considered the most prospective unconventional gas reservoir in west Lithuania, situated in the deep central part of the Baltic sedimentary basin. Hundreds of deep oil exploration wells have been drilled in the area of interest, owing to extensive exploration of oil fields. The lower and middle Llandovery interval was mainly drilled with coring, while most of the section was covered by only logging. Therefore, the knowledge of major parameters of the Lower Silurian shales is rather obscure and is based on scarce rock sample data. The gamma-ray, electrical resistivity and sonic logs were utilised, together with mineralogical studies of rock samples to document vertical and lateral distribution of organic matter. Also, the brittleness index was defined to characterise the whole Lower Silurian section. Some unexpected trends were identified that may redirect exploration strategy in west Lithuania. The combined application of mineralogical studies and well logs indicate a much higher exploitation quality of the Lower Silurian shales than previously believed. A higher organic matter content and brittleness were derived from logging data in the Lower Silurian shales.
