ERTILISER: Contains Nutrients (Nitrogen, Phosphorus and Potassium) and Minerals to increase soil fertility

EXPLANATION:
Fertilisers containing Nutrients and Minerals such as Nitrates, Phosphates, and Potassium are Water-soluble, and hence can dissolve in Water to be absorbed through Plant roots via active transport
These Minerals and Nutrients are essential for Plant growth to increase crop yield
|
IMPORTANCE OF MINERALS (NPK):
NITRATES
Nitrates help Plants produce Amino acids that form Protein to increase biomass - growth
Hence, insufficient Nitrates in Plants can cause poor Plant growth and leaves to turn yellow
PHOSPHATES
Phosphates help Plants convert Amino acids into Protein to increase biomass - growth
Phosphates help increase the rate of respiration to release energy for growth
Hence, insufficient Phosphates can cause poor Root growth and discoloured leaves
POTASSIUM
Potassium regulates the opening and closing of Stomata to allow Carbon Dioxide uptake for Photosynthesis
Potassium allows enables enzyme reactions to occur that produce energy in the form of ATP to facilitate active transport of Mineral ions from the soil
Hence, insufficient Potassium can cause poor growth of flowers and fruits, as well as discoloured leaves
