Soil and water analysis Soil and water analysis Presentation Transcript

  • Soil and water analysis M.ADEEL 10-arid-969 Dept. Soil Science & Soil Water Conservation PMAS Arid Agriculture University Rawalpindi
  • Internship In Soil & Water Testing Laboratory Layyah Muhmmad Adeel 1o-arid-969 BSc(Hons.)Agriculture 7th semester Internship duration 31-07-13 to 30-09-13
  • Introduction About Soil and Water Sampling and Field Visit • Soil sampling was not difficult but it was new experience for me. • Weather was so hot and I was in field at 12:00 p.m clock. • Without feeling any hesitations I just concentrate on our work which was assign to the District Officer Dept. of Soil & Water Conservation Laboratory Dr Abdul Ghafar.
  • Infrastructure Of Soil & Water Testing lab Layyah • Building of Soil & Water testing lab consist of  1 soil & water testing sample preparation room  1 Soil & Water Testing room  2 room for agriculture officers  1 room for District Agriculture officer
  • Soil & Water Testing Laboratory Equipments  Lab equipment was not in good condition due to lack of fund.  There equipment has become olds and experiment result are not satisfactory.  Soil testing lab has almost necessary equipment like PH meter ,EC meter, spectrophotometer, flame photo meter, shaker .  All types of glassware is also available in lab.
  • Establishment Staff Soil & Water Testing Lab District Agriculture Officer 2 Agriculture Officers 2 Lab Attendants 1 Lab Technician
  • Experimental Procedures Of Soil planning • Two sample was taken on one place,first was on 1 to 6 inch and second was 6 to 12 inch. • Both sample was collected in separate plastic bag. • On plastic bag number was mention with pointer for identification. • Almost 7 sample was collected in one plot. • 70 to 80 sample was collected in farmer field which was 12 acre
  • • After drying, granding,sieving the sample they are used for test. • Soil organic matter, soil phosphorus and soil textured ,soil Ec and soil pH was find.
  • Procedure to find the soil phosphorus • Weigh the 2.5 g soil. • Add 50ml NACHO3 • Shake for 30 Mint . • Filter the soil solution • Add the 5ml filtrate in 25 ml volumetric flask.
  • • ADD the 5ml mix reagent in flask. • Before adding the mix reagent in flask 0.264g ascorbic acid is added in 50 ml mix reagent. • Make the volume 25ml. • Blank is also prepared.
  • Continue • Then note the reading on spectrophoto meter . Note the reading check on graph then multiply with 100. • Volume of flask × NACHO3 ppm of p in soil Volume of soil filtrate Weight of soil
  • Criteria of P for soil poor medium adequate 0-7 8-13 14-36 Soil Texture & Phosphorus low Medium heavey Sandy loam, sandy loam Clay loam
  • Soil Organic Matter • Take 1g soil • Add 10ml K2Cr2O7 and shake. • Add 20 ml H2SO4 and shake. • Add 200 ml water and shake. • after cooling add 0.7 g NaF and shake. • Also put the few drop of indicator.
  • Continue • Blank is also prepared. • Titrate by FeSO4 , first blank then sample. • After titration note the reading. • We can find the organic matter by using this formula. (blank – reading)o.698
  • Water Analysis CO3• TAKE the 10 ml water in conical flask • Add the few drop of indicator phenolphthalein • If pink color appear CO3- is present . • If pink color appears then titrate by H2SO4 until colorless. • 0.8 × reading= CO3-
  • Water Analysis……Continue HCO3• By using the same flask add the few drop of methyl orange • Titrate with 0.o1n H2SO4 . • when brick like color is induce then note the reading • by using this formula • (reading × 0.4)=HCO3-
  • Ca+Mg • Take 10 ml water in petri dish from sample • Put the 1 to 2 drop of buffer solution. • Then put 1to 2 drop of chrome black. • The titration should takes place with burrate, in burrate EDTA solution is used. • When the color of water is green blackish.
  • Continue TSS EC 100 = TSS Na Na= Tss – (Ca+Mg)
  • RSC • (CO3- + HCO3-) – (Ca+Mg) • SAR= Na √(Ca+Mg) 2 Cl- • To the same flask addd few drop of indicater patassium chromate. • Titrate by silver nitrate AgNO3 • Titrate until brick red color.
  • Textured of soil SANDY SOIL SANDY LOAM LOAM CLAYEY LOAM CLAYEY ≥ 20 ml water is used 20ml to 30 ml water is used 30 ml to 40ml water is used 40 to 45 ml water is used 760ml water is used
  • SPECIAL THANKS TO MY TEACHERS • Chairman Dept Of S.S & S&WC Prof.Dr. Saleem Akhtar • & • Prof.Dr.Gulam Jailani •& • Dr.Muhammad Irbil
  • ALSO SPECIAL THANKS TO Establishment Staff Of Soil & Water Testing Labs • Dr.Abdul Gafar (D.O) • Mam.Farah (A.O) • Ashraf Bhatti (A.O) • & M.Ameen & Ghulam Farid (Lab Assistant)
