Due to its high organic matter content, sawdust can be used for soil amendment. This study investigated the effect of sawdust obtained from a furniture industry (Yildiz Integre Akhisar flakeboard) on grape yield and loam texture soil (Typic Xerofluvent) properties of a vineyard located in Saruhanlı District, Manisa, Turkey. In the trial, three groups with dry sawdust (10 t ha-1, 20 t ha-1; 30 t ha-1 ) was added to plots of vineyard while 0 t ha-1 or without sawdust addition was set up as a control group. All the 4 treatments were replicated three times (4×3). Sawdust addition resulted in significant increase (p, We would like to thank the factory (Flakeboard Fabric Industry-Yıldız Integrated Wood Industry and Trade Inc. Akhisar, Manisa, Turkey) that supplied the sawdust, which is the trial material. This article was produced from Lelenda Florent Kebalo’s graduate work (Advisor is Prof. Dr. Sezai Delibacak).

International audience; In France, there is a growing demand of locally produced vegetables from urban consumers. Meanwhile, cities and their peri-urban areas are a source of organic wastes (OW) that can be recycled as amendment or fertiliser in agriculture. Our research objective was to investigate the current and prospective uses of OW by market gardeners and fruit growers in three peri-urban areas near Paris (France). We carried out semi-structured interviews with thirty market gardeners and/or fruit growers to study their current fertilisation practices and their perception regarding the potential use of diverse OW available (or probably available in the future). It turned out that the most common OW were green waste compost and horse manure, used mainly as soil amendment. Besides, most farmers used commercial organic fertilisers. Farmers’ perception regarding the potential use of biowaste compost was good, as well as for shredded green waste. However, the farmers were more reluctant to use digestate from biowaste anaerobic digestion and human urine, although they would be suitable OW for the substitution of commercial fertilisers (thanks to a high N availability). This reluctance was mainly explained by sanitary risks, legal barriers, logistic problems or fear of consumer perception. We showed that for farmers, OW had to be considered not only for their fertilisation or amendment role but also for other farming objectives such as mulching. The rates of OW application greatly varied among farmers but were higher than what was usually applied in field crops in Paris region. Based on these figures, we extrapolated the required acreage to recycle all composted organic wastes from private households at the scale of the Ile-de-France (Paris) region. This showed that market gardening and fruit production could play a significant role in recycling OW from cities at the regional level.

Yüksek organik madde içeriği nedeniyle talaş atığı, bir toprak düzenleyicisi olarak kullanımı mümkün görülmektedir. Bu çalışmada, Yıldız Entegre Akhisar Yonga Levha Fabrikası'ndan çıkan atık talaşın Saruhanlı'da bulunan tın bünyeli (Typic Xerofluvent) toprakta yetiştirilen bağın üzüm verimi ve toprak özelliklerine olan etkisi araştırılmıştır. Deneme tesadüf blokları deneme desenine göre, 4 uygulama ve 3 tekrarlamalı olarak kurulmuştur. Uygulamalar: kontrol (0 t da-1), kuru madde olarak 1 t da-1; 2 t da-1; 3 t da-1 talaş uygulamasıdır. Deneme sonunda elde edilen verilere göre, talaş dozları toprağın organik madde, toplam azot, EC, alınabilir Na, Ca, Mg, Fe, Zn, P, K ve Mn içeriği, nemi, doygunluk yüzdesi, tarla kapasitesi, solma noktası, yarayışlı su, agregasyon yüzdesi değerlerini tanığa göre artırdığı ve bu artışların istatistiksel olarak önemli olduğu bulunmuştur. Talaş uygulamasıyla toprağın pH, hacim ağırlığı, toplam mil + kil yüzdesi, süspansiyon yüzdesi ve dispersiyon oranı değerleri istatistiksel olarak düşmüştür. Talaş uygulamaları ile toprağın kireç ve alınabilir Cu içeriği, SSİ, agregat stabilitesi değerlerinde istatistiksel olarak önemli değişim saptanmamıştır. Talaş uygulamaları ile bağın üzüm veriminde istatiksel olarak önemli bir artış belirlenmiştir., Due to its high organic matter content, sawdust waste can be used as soil improver. In this study, the effect of wood sawdust waste collected from Yildiz Integre Akhisar flakeboard plant on grape yield and loam texture soil (Typic Xerofluvent) properties of a vineyard located in Saruhanli was investigated. The fıeld study was established according to a randomized block-design with 4 treatments and 3 replications. Treatments consisted of the control (0 t da-1), 1 t da-1, 2 t da-1; 3 t da-1 of dry sawdust applications. The results at the end of study showed that the sawdust rates increased significantly soil organic matter, total nitrogen, EC, available Na, Ca, Mg, Fe, Zn, P, K and Mn contents, moisture, saturation percentage, field capacity, wilting point, available water, aggregation percentage values according to the control. The values of soil pH, bulk density, percentage of total silt + clay, suspension percentage and dispersion ratio were significantly decreased with sawdust applications. There was no significant change in lime, available Cu contents, SSI, aggregate stability of the soil with sawdust applications. Sawdust applications increased significantly the grape yield of the vineyard.
