EXPLANATION:
Fertilisers are Water-Soluble Minerals that Dissolves in Water to be Absorbed through the Roots of the Plants by Active Transport
They contain Minerals and Nutrients such as Nitrates, Phosphates and Potassium that are Essential for the Growth of Plants, Increasing Crop Yield
|
IMPORTANCE OF MINERALS (NPK):
NITRATES
Helps to Produce Amino Acids in Plants to Make Protein, Allowing Growth of Plant by Increasing Biomass
Lack in Nitrates can Cause Poor Growth and Leaves to Turn Yellow
PHOSPHATES
Allows Plants to Convert Nutrients into Usable Building Blocks for Growth (Amino Acids are building Blocks of Protein)
Helps to Increase the Rate of Respiration to Release Energy for Growth
Lack in Phosphates can Cause Poor Root Growth and Discoloured Leaves
POTASSIUM
Regulates the Stomata to Open and Close to Allow Carbon Dioxide Uptake for Photosynthesis
Allows Enzyme Reactions to Take Place to Produce ATP (Energy) for the Active Transport of Mineral Ions from the Soil
Lack in Potassium can Cause Poor Growth of Flowers and Fruits, as well as Discoloured Leaves
