“…This was earlier supported that the sensitivity of water retention to changes in organic matter content was highest in sandy soils (Rawls et al 2003). Under similar conditions to our study, successive application of composts improved soil physical properties (Agbede et al 2008) and increased water retention capacity due to increased pore volumes and reduced bulk density (Shashoug et al 2017).…”

“…Under the prevailing environmental conditions of our study, Elkerim (2012) found that higher grain yield and yield components of sorghum with application of 15 t ha -1 of compost from farm yard manure. Application of compost in an irrigated sandy loam soils with increased irrigation cycle resulted in similar sorghum yield to recommended irrigation cycle (Shashoug et al 2017). Similarly, due to higher quantity of macro and micronutrients added to the soil in the form of farm yard manure, an increase of 24% in grain yield of millet was reported (Ullasa et al 2017).…”

Sandy desert soil in Sudan are characterised by low content of organic matter, small water holding capacity and low crop productivity. Methods to enhance crop productivity on these environments, such as land application of composts, are of great importance. Field experiments were conducted on a sandy soil to determine the effects of two types of composted manures on growth and yield of two sorghum varieties grown under rainfed conditions. Two sorghum cultivars (Butana and Arfa Gadmak were sown under chicken manure (CM) compost (5 t ha-1), CM compost with NPK (36 kg ha-1), farm manure (FM) compost (20 t ha-1), FM compost with NPK (36 kg ha-1), CM compost with FM compost (1:1, wt/wt, 12.5 t ha-1), CM and FM composts with NPK (36 kg ha-1), only NPK (36 kg ha-1) and control (no composts or NPK). Application of composts increased organic soil carbon by 50% and available phosphorous (P) between 43 to 105%, whereas, pH and bulk density were decreased by 2 and 6%, respectively. Soil moisture contents in compost treated plots were 56–98% higher than control plots. Mixing compost with NPK increased leaf area index over NPK alone by 28% but the highest values were found in plots treated with chicken compost or integrated with NPK compared to NPK application alone. Incorporation of compost increased dry matter yield compared to control by 17–53% and increased grain yield by 1.8 to 3.1 fold in both sorghum varieties. Grain yield from plots treated with NPK, sole chicken compost or combined with NPK were similar for both varieties in both seasons. In general, the trend of grain yield of sorghum was in the order of NPK = chicken compost with NPK = chicken compost = farm manure compost with NPK  mixed compost with NPK = farm manure  control. In conclusion, integrating composts with NPK improved fertility of sandy soils, sorghum growth and yield. © 2020 Friends Science Publishers

“…With increasing energy consumption from renewable sources, sewage sludge (SS) is increasingly seen as a promising fertilizer for energy crops [1][2][3]. Due to the fact that sewage sludge contains large amounts of organic and inorganic nutrients, it can complement or replace chemical fertilizers [4][5][6].…”

Production of Sweet Sorghum Bio-Feedstock on Technosol Using Municipal Sewage Sludge Treated with Flocculant, in Ukraine

et al. 2023

This paper presents the influence of sewage sludge (SS) on the biometric parameters, absorption of mineral elements and thermal characteristics of sweet sorghum (Sorghum bicolor L.) grown on Technosol. Two types of sewage sludge were used: unmodified and modified with DAMET flocculant. Each type of sludge was applied in three doses (expressed as dry matter basis, DM): 20 t DM/ha, 40 t DM/ha and 60 t DM/ha, respectively. The yield of fresh biomass depended on the dose of sewage sludge: it increased by 14.5–41% and reached 104.6 t/ha after application of the sewage sludge with flocculant at a maximum rate of 60 t/ha. Sorghum biomass actively absorbs nutrients from the soil. Nitrogen was absorbed more actively; depending on the type and dose of sewage sludge application, its content in biomass increased from 12–40% (dose of 20 t/ha) to 80–112% (dose of 60 t/ha). By content in sorghum biomass, essential elements can be arranged in descending order as follows: Fe → Mn → Zn → Cu. Sorghum shows a low ability to accumulate some heavy metals in aboveground biomass. Despite the fact that large doses of sewage sludge contributed to an increase in the content of nickel, cadmium and lead in the substrate by 1.8–5.6 times, the ratio of the content of these elements in plants to the content in the substrate remained low. Sewage sludge affects the process of thermal degradation of sorghum biomass. The decomposition of the main components occurs at lower temperatures, and, as a rule, at higher rates. Sewage sludge (especially with flocculant) contributes to a more complete combustion of biomass. The results showed that sewage sludge with flocculant at a dose of 40 t/ha is the most optimal fertilizer option for growing sweet sorghum on such Technosols as loess-like loam.

“…SS is a by product of waste water treatment process, which contains lots of organic matter, plant nutrients (N, P, K, Ca, Mg, etc) and harmful components such as potential toxic heavy metals and pathogenic microorganisms (Delibacak et al, 2020;Kızılkaya et al, 2021). The use of SS in agriculture includes several operations that improve its efficiency in crop production, as compared to mineral fertilizers, which are related to the stabilising process before spreading (Shashoug et al, 2017;Jatav et al, 2021). These are principally aerobic digestion, anaerobic digestion, composting, liming, and pelletisation.…”

The influence of Ilkompost and Micromix bacterial consortium inoculation during sewage sludge (SS) with wheat straw (WS) composting was assessed. The eﬀect of inoculation on compost quality parameters such as pH, temperature, nutrient contents and C/N, bacterial and fungal population were determined. Compared to the control treatment, the temperature of piles and population of microorganism increased after inoculated bacterial consortiums at the beginning of compost. But, WS addition did not effect on compost quality parameters and microbial population. Fungal and bacterial population, the peak temperature, or heating rate, of Micromix bacterial consortium based on Streptomyces pratensis, Bacillus mesentericus, Azotobacter chroococcum inoculated treatments was clearly higher than that of Ilkompost bacterial consortium based on Pediococcus pentosaceus, Streptomyces sindenensis, Bacillus megaterium inoculated treatments
