fertilisers
Plant growth boosters
Fertilisers is the British spelling of fertilizers—substances added to soil or plants to promote growth.
Fertilisers supply nutrients like nitrogen, phosphorus, and potassium that plants need but soil may lack.
They range from organic materials like manure and compost to synthetic chemical compounds: The farmer spread fertilisers across the field before planting.
