Introduction

NPK 15:15:15

 
NPK represents the key constituent chemical elements Nitrogen (N), Phosphorus (P) and Potassium (K) used in plant fertilisers.

The percentages are shown as numbers, e.g. 10-8-12, where the first number is N, the second P and the third K.

The 3 elements promote plant growth in 3 different ways. In simple terms, these are:

N – Nitrogen: promotes the growth of leaves and vegetation
P – Phosphorous: promotes root growth
K – Potassium: promotes flower and fruit growth

When choosing plant fertilisers, the NPK values help you to identify the best fertiliser for the job in hand. For example, lawn fertiliisers are typically higher in Nitrogen to promote leafy growth of the grass.

A balanced fertiliser is when the 3 chemical nutrients NPK are included in equal measures and reflected so in the ratio e.g. 5:5:5. A balanced fertiliser is good for all round, general use.

NPK available to Valetime is a balanced fertiliser with the 3 chemical nutrients balanced in the ratio 15:15:15.

Effects of Overdose: Ingestion of large doses may cause diarrhea, nausea, abdominal cramps or formation of methemoglobinemia. Seek medical attention.

FIRST AID MEASURES

Ingestion: If large amount is ingested, give 2-3 glasses of water and induce vomiting. Seek medical attention. Inhalation: Remove to fresh air. Seek medical attention if condition persists. Eyes: Flush eyes with running water for at least 15 minutes. Seek medical attention if condition persists. Skin: Wash with soap and water. Seek medical attention if condition persists. Notes to Physician: Consult standard literature. Treatment based on the sound judgment of the physician and the individual reactions of the patient.
