ProloNg 46-0-0 Slow Release Fertiliser 20kg

Prolong 46-0-0 is a straight nitrogen fertiliser which will release over a 6-12 month period. Allowing the plant to draw on available nitrogen over several months is far more efficient and reduces the amount of nitrogen lost to the atmosphere. Using a slow release fertiliser will also reduce the sudden surge of top growth usually associated with high nitrogen products.

Nitrogen is crucial for the healthy growth of plants. Part of the cholophyll molecule, nitrogen gives plants their green colouration and is involved in the process of photosynthesis. The main symptom of a lack of nitrogen in plants is usally a general yellowing (chlorosis) of the green leaves.

If you require a slow release product which contains additonal nutrients, consider 18-3-8 Slow Release.

Understanding Fertiliser Analysis:

• Under the metric system the unit of measurement is a kg.
• Recommendations are given in kg/ha.
• A fertiliser with the analysis 46:0:0 contains: 46% nitrogen 0% phosphate 0% potash
• So in a 20kg bag: 46% of the 25kg is Nitrogen i.e. 9.2kg N, 0% of the 25kg is Phosphate i.e. 0kg P, 0% of the 25kg is Potassium i.e. 0kg K
