Mineralogical, chemical and solubility versions during the Eppawala phosphate deposit of Sri Lanka — a scenario for selective mining for fertilizers
We undertook meta‐Evaluation of experimental and quasi‐experimental studies to look at the effect of agricultural input subsidies on adoption, productivity, family cash flow and poverty. The findings for Main outcomes are as follows: • Adoption: Meta‐Evaluation of 7 experimental and quasi‐experimental studies indicates an increase in adoption by 0.

A relatively small amount of suitable scientific studies were being identified, and nicely‐documented study in nations past sub‐Saharan Africa is required to make sure the wider relevance of these results. Mixed‐techniques, idea‐centered impact evaluations would assist take a look at the impacts of various amounts of subsidies for various beneficiaries.
End users looking for the bottom fares to Sri Lanka ought to take into account traveling on Friday evenings, when prices are generally cheapest. Budget-minded travellers will want to avoid Tuesday at midday, when prices are often at their maximum.
At Eppawala in Central Sri Lanka, a thick weathering profile is mined to be used as phosphate fertilizer. New tropical subaerial weathering procedures have manufactured a phosphate-enriched horizon while in the weathering profile that has formulated with a Precambrian apatite marble formation. The enriched horizon with P2O5 compositions starting from ten to forty% is formed essentially of laminar phoscretes ... [Display total summary] developing inside of a community of sinkholes.In-depth evaluation with the laminar phoscretes reveals that Principal metamorphic apatite crystals arise in association with phosphatic allochems which include coated grains, ooids, pisoids and intraclasts inside of a finely layered groundmass.

Although addition of rock phosphates increased yields of those crops, the raises were pretty smaller when compared to People obtained through the addition of TSP. However P is high in SERF as compared to ERP the availability of P from SERF was not top-quality to ERP. The readily available phosphorus material at the conclusion of Each and every crop showed optimum values in TSP- treated plots, followed by IRP, SERF and ERP. These results propose that rock phosphate sources for example SERF, IRP and ERP have been inferior to TSP instead of ideal for direct application as sources of P fertilizer for potato and vegetables.
The target of the analyze is to make use of knowledge envelopment Assessment in measuring and examining the price performance and performance scores of 7 selected paddy developing locations to the period 2002-2008 in Sri Lanka. Expense efficiency viewed as one of the most important style of efficiency that areas can achieve it by obtaining a mix of inputs which help them to produce the specified outputs at ... [Present full summary] least Expense. Allocative efficiency refers to the selecting of inputs to the precise degree of output at specific standard of input prices, at least Value. The panel info which includes quantities of paddy generate, labour, fertilizer and prices of labour and fertilizer were collected from yearly experiences of expense of cultivation and the info envelopment analysis was applied to estimate allocative and cost efficiency of paddy production. The above mentioned variables had been used in the consistent returns to scale with enter-orientated data envelopment model to work out both efficiencies making use of DEAP Model 2.
This analyze makes an attempt to estimate the output offer and enter demand elasticities of rice production using the restricted normalized translog earnings perform to the 4 main paddy creating districts; Anuradhapura, Hambantota, Kurunegala and Polonnaruwa in Sri Lanka. In addition, elasticities of substitution concerning inputs may also be estimated. The effects recommend which the alterations in market prices of inputs and output considerably have an impact on the farmers’ revenue, rice offer and using resources in paddy cultivation. The availability elasticity of rice with regard to its very own price is 0.five and the provision elasticity of output with regard to fertilizer price is -0.
The fluoride adsorption on to apatite is strongly pH dependent and the very best fluoride removing was observed at pH 6.0, when adsorption decreases each at minimal and superior pH ranges. The proportion fluoride removing raises While using the absorbent dosage mainly because of expanding the number of adsorption internet sites, but the optimum adsorption is often attained utilizing modest Original quantities of apatite during the suspension. The sorption procedure was quite swift and the most adsorption was achieved inside the first 10 min in a solution containing 15.0 mg/L fluoride at pH 6.0. The kinetic reports confirmed the fluoride removal method follows pseudo-2nd-buy kinetics. The Langmuir isotherm finest equipped (R
