  1. FERTILIZER and ORGANIC AMENDMENT Tariq Mahmood 2008-ag-1586

  2. What we discuss? • Introduction and Definition • Brief history • Why we use it? • Organic amendments • Soil condition of Pakistan • Need of fertilizers • Different synthetic fertilizers in Pakistan • Different organic fertilizers in Pakistan • What we do?

  3. Introduction The term fertilizer refers to any substance, which supply one or more of the mineral element essential for plant growth.

  4. Definition Fertilizer is any organic or inorganic material of natural or synthetic origin that is added to a soil to supply one or more plant nutrients essential to the growth of plants. Organic fertilizer Inorganic fertilizer

  5. Conti… A recent assessment found that about 40 to 60% of crop yields are attributable to commercial fertilizer use.

  6. History In Neolithic (New Stone Age, beginning about 9500 BC)man probably used fertilizers. The first fertilizerproduced by chemical processes was ordinary super phosphate made early in the 19th century.

  7. Conti… The Potash fertilizer industry started in Germany in 1861. The first synthetic Nitrogen fertilizer was calcium nitrate, made in1903 The synthetic ammonia available after 1913

  8. Why we use fertilizer? Agricultural scientist Carl Sprengel 200 years ago Plants need sunlight water minerals

  9. Conti… In 1828, 12 nutrients So, we use fertilizers for Good yield Replace the nutrients Fertility status of soils

  10. Organic amendment Amendment means An improved change made to a previous status soil amendment Two broad categories organic inorganic.

  11. Conti… Organicamendments come from something that is or was alive. e.g. straw, compost, manure. Inorganicamendments, are either mined or man-made. e.g. tire chunks, gravel and sand.

  12. Conti… Organic amendments increase soil organic matter content and offer many benefits. Soil aeration, water infiltration, water and nutrient-holding capacity. Organic matter also is an important energy source for bacteria, fungi and earthworms that live in the soil.

  13. Soil condition (www.pakissan.com) In Pakistan, the soils are very poor in organic matter. A soil having 1.29 % C is considered to be sufficient in organic matter, it is reported that the range of soil carbon in Pakistan soils is 0.52 to 1.38% in different soil series. Most of them have less than 1%.

  14. Reasons • Parent material and Climatic Conditions • Intensive Tillage • Inorganic farming • Improper Use of synthetic Fertilizers

  15. Need Increased Population Food problems Small land holdings Increase yield Fertility status

  16. Conti… Now a days • More use of synthetic fertilizer, demerits • Less use of organic fertilizer, merits

  17. Synthetic fertilizer (www.engro.com) • Engro urea 46% N pH value of 6.8

  18. Conti… • Engro DAP 46% P2O5 18 % N More than 90 % of Phosphorus is soluble pH value of 7.33

  19. Conti… • Engro Zorawar is one of the highest grade phosphatic fertilizers 52% P205 11% N 2% sulphur 1% calcium acidic in reaction {pH = 3.5}

  20. Conti… • Zarkhez homogenously granulated fertilizer 08% N 23% P2O5 18% K

  21. Conti… • Zingro (Danedar), Zingro is a zinc fertilizer It is 99.9 % soluble In water. Chemically it is a zinc sulphate Minimum 33% zinc

  22. Organicfertilizer • Farmyard manure • Poultry manure • Crop residues • Green manure • Slaughter house waste • Compost • Biogas compost

  23. Conclusion Our Responsibility is: • Awareness among farmers • Yield Enhancement in relation to fertilizer • Balance use of fertilizer • Organic farming
