“…The highest and lowest values were obtained from plots with the highest rate (30 t ha -1 ) and plots without any sawdust addition, respectively. Similar results were obtained in many other studies when organic materials were applied (Demir and Gülser, 2015;Delibacak and Ongun, 2016;Alvarenga et al, 2017). This result could be attributed to the high organic matter content of sawdust (approximately 68%) used in the experiment.…”

Article InfoDue 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 <0.05) of soil organic matter, total nitrogen, electrical conductivity (EC), available Na, Ca, Mg, Fe, Zn, P, K, and Mn contents, moisture, saturation percentage, field capacity, wilting point, available water and aggregation percentage values compared with control group. Also, the soil pH, bulk density, and dispersion percentage significantly decreased with sawdust addition. However, there was no significant change in lime, available Cu contents, structure stability index, aggregate stability of the soil with sawdust addition. Compared with control group, addition of 20 t ha -1 and 30 t ha -1 of dry sawdust significantly increased the grape yield of the vineyard. The highest yield of 4.23 t ha -1 was recorded with 30 t ha -1 sawdust addition. Sawdust can be used as a soil amendment given its positive effects on some soil properties and grape yield of the vineyard. It is suggested that nitrogen immobilization from the soil by microorganisms due to sawdust's high C/N ratio is a key consideration for its future use.

“…Furthermore, the effects were only observable with the 40 t/ha application rate of TSC pointing to a dose-dependent effect. 44 Although Delibacak and Ongun 15 recommended a 1-month waiting period before planting or sowing activities when soil is amended with uncomposted tobacco waste, the present study indicated that a shorter waiting period of at least 1 week may be adequate. A shorter waiting period may reduce opportunities for nutrient loss, thus fostering optimum nutrient utilisation.…”

“…Soil amelioration with tobacco waste (Nicotiana tabacum L.) has been shown to be beneficial in improving the productivity of various horticultural crops including lettuce (Lactuca sativa), spinach (Spinacia oleracea) and tomato (Lycopersicon esculentum). [15][16][17] Further, soil biological and physical properties have also been enhanced by tobacco waste application in other parts of the world. 18,19 Tobacco waste nutrient levels in the range 1.97-2.38% N, 0.21-0.50% P, 0.32-1.03% K and 38-41% C have been documented, 19,20 pointing to its potential value as a nutrient resource.…”

Nutrient uptake, yield and taste of oilseed rape (Brassica napus L.) and soil chemical properties following amendment with uncomposted and composted tobacco waste and cattle manure

The inadequacy of the nutrient supply of most tropical and sub-tropical soils may be curbed through organic material recycling, thus reducing the need for mineral fertiliser use. To promote tobacco waste recycling in a smallholder food-cash crop production system, nutrient uptake, dry biomass yield and taste of oilseed rape (Brassica napus L.) and soil chemical properties were determined on a sandy loam soil under field conditions. The experiment was a randomised complete block design with three blocks and eight treatments, namely, control (no amendment), mineral fertiliser (121, 30.8, 24.6 kg/ha N, P and K, respectively), uncomposted tobacco leaf scrap (TSC) and compost of TSC and cattle manure (TSC-CM) at 5, 20 and 40 t/ha. N, P and K uptake and dry biomass yield of oilseed rape were higher (p<0.05) than control with 40 t/ha TSC-CM and mineral fertiliser application at 3 weeks after transplanting (WAT), while significant improvements with TSC were observed from 5 WAT. Mineral N, extractable P and exchangeable K were higher than control with TSC-CM at 20 t/ha and 40 t/ha at 3 WAT, and higher with TSC at 9 WAT. Soil organic carbon was more improved with TSC application than TSC-CM at 9 WAT. Organoleptic testing revealed an intensely bitter taste in oilseed rape with mineral fertiliser, 20 t/ha and 40 t/ha TSC at 3 WAT, although it diminished with time. A trade-off of nutrient uptake, yield, taste of oilseed rape and soil properties improvement is attainable with application of TSC-CM at 40 t/ha, while if composting is not feasible, TSC application at 20 t/ha is a viable alternative. Thus, judicious utilisation of tobacco waste offers a viable solution to the problem of low soil fertility on sandy soils and can reduce the need for mineral fertiliser use, while promising sustainable soil management.

“…The primary cause of this is the mesolithic composting phase that vermicompost undergoes following thermolithic composting, which causes further disintegration. Vermicompost (Erdal et al 2000) [44] , which produces a substance rich in humic acids, aids in the development of roots and increases plant biomass (Delibacak and Ongun 2016) [37] . Vermicomposting can raise the soil's nitrogen content by 42%, phosphorus by 29%, and potassium by 57%.…”

The sustainable intensification of agriculture necessitates innovative approaches to enhance soil quality and crop productivity while minimizing the negative environmental impacts of conventional farming practices. Vermicompost, a nutrient-rich organic material produced through the decomposition of organic waste by earthworms, has gained significant attention as a potential solution to address these challenges. Vermicompost is rich in essential plant nutrients, organic matter, beneficial microorganisms, and growth-promoting substances. Its application to soils has been demonstrated to ameliorate various soil properties, including improved soil structure, increased waterholding capacity, enhanced nutrient retention, and increased microbial activity. These improvements contribute to overall soil health and fertility, leading to enhanced plant growth and productivity. The introduction of vermicompost into agricultural systems has shown several positive effects on crop growth and development. These effects encompass increased germination rates, improved root development, enhanced nutrient uptake, and heightened resistance to pests and diseases. The benefits of vermicompost application extend beyond the improvement of soil physical and chemical properties. By recycling organic waste materials, vermicomposting contributes to waste reduction and environmental sustainability. By bridging the gap between waste management and agricultural productivity, vermicompost emerges as a valuable tool in promoting both environmental conservation and food security.
