Sas-Paszt, L., Pruski, K., Żurawicz, E., Sumorok, B., Derkowska, E. and Głuszek, S. 2014. The effect of organic mulches and mycorrhizal substrate on growth, yield and quality of Gold Milenium apples on M.9 rootstock. Can. J. Plant Sci. 94: 281–291. A 3-yr study was conducted to evaluate the effects of organic mulches and mycorrhizal substrate on growth and yield of apple cv. Gold Milenium grown on M.9 rootstock. Straw (rye), pine bark, conifer tree sawdust, compost (plant debris), cow manure, peat moss substrate (commercial), and mycorrhiza substrate (Mykoflor®, containing mycorrhizal fungi: Glomus intraradices, G. mosseae, G. etunicatum) were applied in spring of each year. All the applied treatments did not affect significantly the tree growth. Mulches did not have a positive effect on total soluble solids of the fruit and the number of fruits in different size categories. Only sawdust mulch significantly increased the number of fruit in size diameter class of 7.0–7.5 cm compared with the control. The use of mulches affected the concentration of macro- and microelements in leaves, particularly Cu, Fe, Mn and Zn. Mulches positively affected the pH and organic matter content of soil. The best results were observed with the use of the compost, cow manure and the mycorrhizal substrate, where the concentrations of P, K and Mg, most of microelements and soil organic matter were elevated.

Set Up

The aim of this study was to assess the effect of composting process of cow manure and rice straw with application of cow urine and to evaluate the quality of composting products. There were two treatment piles, in which one pile was applied with cow urine every week and another pile without urine application. Each pile was set up by one tone cow manure and 500kg rice straw. The piles were half-covered by plastic foil to protect from rain and turned one a week. The composting duration lasted 8 weeks. The parameters such as temperature, pH, DM, density and nitrogen were monitored and observed during the 8-week period. The results showed that there was a significant difference in temperature, compost quality and duration between two piles with and without cow urine application. The application of cow urine increased significant nitrogen and phosphorous content and shortened the composting process. This study recommends that cow urine should be applied for composting process of cow manure and rice straw in order to increase the quality of compost. The final product was in the range of matured compost level and can be used directly for agriculture crop. Mục tiêu của nghiên cứu nhằm đánh giá ảnh hưởng đến chất lượng phân compost của việc bổ sung nước tiểu vào trong quá trình ủ phân từ nguyên liệu phân bò và rơm rạ. Thí nghiệm được thực hiện trên hai đống ủ phân, một đống ủ được bổ sung nước tiểu bò hàng tuần và một đống ủ không bổ sung nước tiểu bò như là một nghiệm thức đối chứng. Mỗi đống ủ được trộn 1 tấn phân bò và 500kg rơm. Đống ủ phân được đậy kín một nửa phía trên nhằm ngăn cản ảnh hưởng của mưa và được đảo trộn một lần mỗi tuần. Quá trình thí nghiệm được tiến hành trong 8 tuần. Các chỉ tiêu như nhiệt độ, pH, DM, mật độ và chất dinh dưỡng Nitơ và Phốt Pho được quan trắc trong thời gian ủ. Kết quả cho thấy có sự khác biệt đáng kể giữa hai đống phân ủ đối với các chỉ tiêu như nhiệt độ, chất lượng phân compost và thời gian ủ. Đống ủ phân có bổ sung nước tiểu có hàm lượng Nitơ và Phốt pho cao hơn và thời gian ủ ngắn hơn. Kết quả nghiên cứu khuyến cáo nên bổ sung nước tiểu bò cho quá trình ủ phân compost nhằm tăng hàm lượng chất dinh dưỡng cho sản phẩm phân compost. Sản phẩm sau quá trình ủ đạt mức độ phân hữu cơ và có thể sử dụng cho cây trồng.

Promising Solution

Anaerobic co-digestion provides a promising solution for converting inexpensive carbon from wastes to biogenic methane. We used microalgae (Nannochloropsis oculata) with cow manure and sludge to produce a better quantity and quality of biogas. To further improve the gas production, microalgae were pretreated with ultrasonication, hot water, and a combination of both. Interestingly, the results showed that the pretreatment of microalgae decreased biogas production by 5 to 30%. The no-pretreatment runs produced a maximum of 118 L of biogas. The relative content of biogenic methane was higher in the pretreated feedstock (48 to 52%) in comparison with the no-pretreatment runs (44%). The conversion of volatile suspended solids present in the feedstock to total biogenic methane production was highest in hot-water-treated runs. The carbon content in the gas produced by the pretreated microalgae peaked (38%) in the middle of the experiment (i.e., at 45 days), whereas for no-pretreatment runs, the content remained constant from the start to the middle and declined (from 36 to 34%) at the end of the experiment (i.e., at 90 days). We also report the chemical structure of microalgae with and without pretreatments.

Growth and physical quality of <em>Paraserianthes</em> <em>falcataria</em> (L) Nielsen seedling is determined by the quality and quantity of transplanting media. The aim of this research is to determine the best transplanting media for growing<em> P. falcataria</em> seedling. Research started with sowing <em>P. falcataria</em> seed in plastic container until the seedling grow. After 2 weeks of age, seedling was placed in ten types of transplanting media. Transplanting media consist of Sidoarjo’s mud soil, rice husk, compost and cow manure. Each types of transplanting media were made from different concentration of mud, rice husk, compost and cow manure. Result showed that the highest growth of <em>P. falcataria</em> seedling was found in M4 with 31.0 cm. However, this result was not significantly different with M1 which the high is 30.6 cm. Other <em>P. falcataria</em> seedlings showed varied growth with the value ranging from 27.6 to 29.9 cm. M4 also showed highest stem diameter, root length and leaves number with value 0.50 cm; 20.6 cm; 50.1 respectively. Root dry weight and stem+leaf dry weight were also highest on M4 with value 1.4g and 4.9g. RRSL and Seed Quality Index were also highest on M4 with value 3.50 and 0.09. It was concluded that M4 is the best transplanting media for <em>P. falcataria</em> seedling.
