...treatment. Bulk density, porosity and organic matter were significantly improved by the cattle manure and compost treatments. The moisture content and water holding capacity revealed non – significant effect of the treatments. It may be concluded from the current research that water use efficiency in term of grain yield was higher in the treatment plots receiving mineral fertilizer but compost and manures were comparable and showed significant improvemen...

...content,bulk density and porosity associated with wheat grain yield were evaluated. Seven tillage treatments were applied in the fallow periods (summer seasons) of both years before sowing of wheat crop. These tillage treatments were (i) Once Mould board plowing followed by 8 cultivations with planker (1 MBP + 8 CS) as a check, (ii) No-till followed by twice application of glyphosate herbicide (NT + GH), (iii) Once Mould board plowing followed by twice applica...

... 7-12% and increased the porosity by 9-14%, saturation water by 9-20% and available water by 19-29%. However the INM5:75,10:50, 15:25, closely followed the FYM5,10,15,20 with reduction in BD by 9-11% and increased in porosity by 11-13%, saturation water by 14-17% and available water by 25-30%. All interactions remained non-significant. These results concluded that integrated nutrient management improved the soil OM, micro-nu...

...ρ) lowered by 4% and porosity (ƒ) saturation (ω) and available water content (θ) increased by 3.6%, 5% and 11%, respectively, over the RD. The cereal-legume rotation recorded 16, 15 and 32% higher total N, mineral N and soil OM, respectively, whilst it reduced ρ by 3% with increase in ƒ, ω and θ by 3, 11 and 3% over the cereal-cereal rotation, respectively. The study concluded that yield potential and fertility status ...

Soil Properties and Crop Yield under Different Tillage Practices in Upland of Balochistan

...bulk density, total soil porosity, soil temperature, crop biomass and crop yield. The results revealed that TOC under ZT (0.57%) was increased significantly. EC of ZT (0.314 ds m-1) was decreased numerically, but pH was not affected by tillage treatments. No significant difference regarding SWC, soil temperature, infiltration rate was observed under different tillage treatments, but the results under ZT were appriciable and CT (1.28 g cm-3) showed significantl...

EFFECT OF POROSITY ON MECHANICAL PROPERTIES OF DIE CAST ALUMINUM ENGINE BLOCK

...mperfections, especially porosity in Aluminum alloy engine block plays a major role in determining the
mechanical properties. An experimental study was carried out to investigate porosity in samples taken from different
locations of the engine block, i.e. thick and thin sections. The samples were extracted from thick and thin sections of
the engine block, having section thicknesses of 20 mm and 5 mm, res...

Selective Capture of CO2 from Mixture of Different Gases using Cellulose Acetate, Polyimide, Polysulfone and some other Polymers based Mixed Matrix Membranes: A Review

...le, polymer of intrinsic porosity, polyurethane, chitosan and many more. Likewise, along with other fillers, Metal organic frame works have also been tested as additive for the mixed matrix membranes as they offer several advantages over other fillers. This review majorly presents use of three polymers viz. cellulose acetate, polyimides and polysulfone, for fabrication of mixed matrix membranes. All of these polymers are of utmost industrial importance in the ...

Mathematical Modeling and Optimization of Physical Properties of Paddy as Influenced by Drying

The results further revealed that the effect of temperature and time on paddy decreased with process except porosity and hardness, which increased as affected by these conditions. The results showed that the model work was valid for p...

A Study of the Distribution of the Tigris River Sediments and the Variation of their Chemical, Physical and Mineral Properties and the Effect Caused by Kut Dam

...d bulk density and total porosity of the soil between the front and rear of the Kut Dam. There was also a variation in the size distribution of some sand fraction. As for the sand minerals, a discrepancy was noted in some heavy and light sand minerals between the front and rear of the dam. It was found that both the difference in the mineral content of the sedimentary cycles and the effect of the Kut Dam on the velocity of the flow of the river load had a role...

...nsity, particle density, porosity, macro pores, initial soil moisture, and organic matter. Coconut plants are considered better for the purpose of vegetative soil and water conservation than Mahogany. However, Mahogany must be arranged at the upper plot and Coconut at the lower plot to enhance runoff reduction. Coconut can reduce the volume of surface runoff significantly so that the erosion rate becomes smaller. Coconut roots function to stabilize the physica...
