Solution
Chemical fertilizer N.P.K:
NPK refers to the three nutrients that constitute complete fertilizers: nitrogen, phosphorus, and potassium.
Because each of the three numbers specifies the percentage of that ingredient in the fertilizer's makeup, a percentage sign is also suggested after each number.
Examples:
Urea, Chitosan, Cadmium, Biochar, Manure, Compost, Fertilizers, and Nanoparticles are examples of N.P.K. fertilizers.
