Biostimulants

  1. 1. BIOSTIMULANTS Ammara Jabeen Muhammad Anam Kashaf Fatima Komal Bhatti Khubaib ul Hassan
  2. 2. CONTEXT  Introduction  Main categories of plant biostimulants  Humic and Fulvic acids  Protien hydrolysates and N-containing compounds  Seaweed extracts and botanicals  Inorganic compounds  Beneficial fungi  Beneficial bacteria
  3. 3. CONTEXT  Common features of biostimulants  Defining plant biostimulants : aiming at a consensus  Regulation of plant biostimulants  Difference between biostimulants and biofertilizers  Challenges  Apportunities  Examples
  4. 4. INTRODUCTION  “Materials that, in minute quantities, promote plant growth” (1997, Zhang and Schmidt)  “Biostimulants are materials, other than fertilizers, that promote plant growth when applied in low quantities” (Kauffman, 2007)  European biostimulant industry council  Biostimulant coalition, USA
  5. 5. HUMIC SUBSTANCES  Sources:  Organic matter  Composts & vermicompostes  Mineral deposits  Agricultural by-products  Soil fertility  Root nutrition  Respiration  Stress protection  Hydroponically grown maize
  6. 6. PROTEIN HYDROLYSATES & N- CONTAINING COMPOUNDS  “Amino acids and peptides mixtures are obtained by chemical and enzymatic protein hydrolysis from agro-industrial by- products, from plant and animal source”  Betaines, polyamides, non-protein amino acids  Anti-stress properties  TCA cycle  Antioxidant activities  Microbial biomass and activity  Soil reparation  Soil fertility
  7. 7. SEAWEED EXTRACTS & BOTANICALS  20 seaweed products  Growth promotion  Gel formation  Water retention  Soil airation  Fixation and exchange of caton  Fixation of heavy matels  Soil microflora
  8. 8.  Seed germination  Hormonal effects  Botanicals:  Food ingredients  Plant protection products  Allelochemicals
  9. 9. INORGANIC COMPOUNDS  Chemical elements that promote plan growth and may be essential to particular taxa ,but are not required by all plants  MAIN ELEMENTS i. Al ii. Co iii. Na iv. Se v. Si  Complex bio stimulants like extract of seaweeds and animal waste  Inorganic salts of beneficial elements
  10. 10. BENEFICIAL FUNGI  Mycorrhizal fungi  Arbuscule forming mycorrhiza (AMF)  Rhizobacter  Metagenomics  Fungal based products  Fungal entophytes like trichoderma SPP.
  11. 11. BENEFICIAL BACTERIA  Bacteria interact with plants in all possible ways  Mutualism and parasitism  Bacterial niches  Participation to the biogeochemical cycles  Main bio stimulants  Mutualistic endosymbiosis of the type rhizobium  Mutualistic rhizospheric PGPRs (plant growth promoting rhizobacteria )
  12. 12. Features of Biostimulants  Nature of Biostimulants  Action on Plant Processes
  13. 13. Nature Of Biostimulants Substance Micro- organism Organic Compuonds Inorganic Molecules
  14. 14. Action on Plant Processes  Cellular Mechanism  Plant Physiology  Agricultural function  Economic and Environmental Benefits
  15. 15. PLANT RESISTANCE AGAINST STRESS CONDITIONS Biostim ulant Reactive Oxygen Scavengi ng  By antioxid ants Cellular Mechani sm
  16. 16. REGULATION OF PLANT BIOSTIMULANTS  Very complex  Difference between biostimulants, bio fertilizers, soil improvers  Route for regulation in Europe  National regulation on fertilizers(fertilizers rout)  European pesticide law  Plant protection products (PPPs)
  17. 17. MARKET OF BIOSTIMULANTS  Market data is scarce  Limited reliability  Regulatory status diverse
  18. 18. CHALLENGES  Scientific challenges  Technical challenges  Regulatory challenges
  19. 19. APPOTUNITIES  Market is growing 10% (EBIC)  Awarness  Environmental policies  Relatively high investment of companies  Horticulture agricultural crops
