To explore the potency of cow urine on biogas production and fertilizer quality of the biogas slurries, six experimental trials,  T0 (50% CD:50% Water) as control, T1 (10% CD:90% CU), T2 (20% CD:80% CU), T3 (30% CD:70% CU), T4 (40% CD:60% CU) and T5 (50% CD:50% CU) were constructed  by mixing cow dung (CD) and cow urine (CU). Cumulative gas volume was estimated for 30 days and the physicochemical properties of the slurries were evaluated. The cumulative gas volume of three trials (T3, T4 and T5) was higher than control (T0) and T5 showed maximum (28% over the control). Moreover, all of the trials except one (T1) showed higher gas yield than control (T0) of which maximum conversion of volatile solid (VS) to gas was obtained in T3. pH of the amended samples were above 7.0 (pH 7.00-7.42). Conductivity of the samples also increases (1.94-13.40 mS cm-1) with the increase in cow urine percentage. With respect to macronutrient (N, P, K) cow urine amended samples can be considered superior to the control one. Moreover, C/N ratio of all the amended samples were below 15 (4.7-14.0) and thus these are suitable for agronomic uses.

Flax Straw

The article presents the results of tests on tribological and physicochemical properties of plastic greases, in which the dispersing phase was highly refined mineral oil and the dispersed phase (thickener) lithium stearate. The functional additives were biocarbon, which were obtained in the pyrolysis process of waste of natural origin, i.e. stems with corn leaves, wheat straw, flax straw, and cherry stones. The compositions containing 5% m/m biocarbon were prepared. Their evaluated on the functional properties of plastic greases was assessed. Tribological characteristics of the greases compositions were determined using the T-02 tester in accordance with the requirements of the subject standards. The effect of biocarbon used on anti-wear (Goz) and anti-seizing (Pt, poz) plastic greases was determined. An assessment was also made of the effect of plant biocarbon on changes in basic physicochemical properties of the composition of plastic greases, i.e. penetration, dropping temperature, and thermo-oxidative stability. It was found that some of the biocarbon significantly improve the tribological properties of plastic greases without significantly affecting the change of key physicochemical parameters. The most beneficial impact of the tested additives on the operational properties of plastic greases was observed when using biocarbon from wheat straw. In some cases, a lower oxidative resistance of biocarbon grease is observed compared to grease without the addition of biocarbon.

Vegetative And Reproductive Growth

Growth substrates (polyester wool, rice husk, and wheat straw), along with soil as control treatment, were compared for vegetative growth, yield, and quality of strawberry cv. Chandler. All growth substrates tested showed good results in terms of growth rate as compared with control. Strawberry plants grown in polyester wool showed the highest (89.50%) survival rate as compared to rice husk (70.50%), wheat straw (64.63%), and control (67.56%). Moreover, a significant increase was observed among number of flowers, fruits, and yield in plants grown in polyester wool. Besides, a significant high amount of total soluble solids (TSS) (12.38 ºBrix), titratable acidity (TA) (1.21%), ash (0.72%), vitamin C (37.39 mg/100 g), total carotenoids (3.90 µg/100 g), and total anthocyanins (3.47 cyanidine-3-glucoside/100 g) was recorded in fruits grown in polyester wool as compared to control. From these results, it can be concluded that the use of polyester wool as a growth substrate for strawberries can give higher yield and better fruit quality.
