Consider the following pairs:1. Biostimulant Categories - Example1. B...
1. Botanical Extracts - Seaweed:
This pair is correctly matched. Botanical extracts like seaweed are commonly used as biostimulants to enhance plant growth and improve stress tolerance.
2. Protein Hydrolysates - Spirulina:
This pair is incorrectly matched. Protein Hydrolysates used as biostimulants usually refer to products derived from the enzymatic hydrolysis of proteins from sources like soy or animal waste, not specifically Spirulina, which is more commonly associated with biofertilizer applications.
3. Humic Acids - Coal:
This pair is incorrectly matched. Humic acids are derived from organic matter such as decomposed plant material and peat, not directly from coal. Coal is not a source for biostimulants.
4. Live Microorganisms - Rhizobium:
This pair is incorrectly matched. Rhizobium is primarily used as a biofertilizer to promote nitrogen fixation in legumes, not as a biostimulant. Biostimulant live microorganisms exclude biofertilizers like Rhizobium and focus on other beneficial microorganisms not involved in nutrient fixation.
Only the first pair is correctly matched, thus the correct answer is Option A: Only one pair.
