- Free-flowing (easily applied)
- Consistent in particle size with smooth and hard granules.
- Easily spread – ensuring even distribution patterns.
- Quickly dissolve when in contact with moist soil or water (avoid run-off)
- Free from contaminants and additives.
What happens when too much fertilizer is used?
Excess fertilizer alters the soil by creating too high of a salt concentration, and this can hurt beneficial soil microorganisms. Over- fertilization can lead to sudden plant growth with an insufficient root system to supply adequate water and nutrients to the plant.
Can too much Fertiliser kill plants?
Too much fertilizer can also cause problems and plant death because FERTILIZER IS SALT. This is because the potential of the plant to pass water out of and into the root system must be lower than that of the soil’s holding capacity instead of the other way around.
What are the benefits of organic fertilizer to the plant and soil?
The use of organic fertilizers has advantage of being cheap, improving soil structure, texture and aeration increasing the soils water retention abilities and stimulating healthy root development. Organic fertilizer has many sources such as minerals, animal source, sewage sludge and plant.
How does manure affect plant growth?
Organic manure is a natural source of nitrogen (N) formation process in the soil. Microbial populations intensively induce the production of phytohormones such as gibberellin and auxin in plant roots grown in fertile soil with rich organic manures which stimulate plant growth [13].
How does fertilizer affect soil quality?
Inorganic fertilizer made the soil more acidic. Manure increased soil organic carbon for all the measured soil depths compared to inorganic fertilizer and control treatments. More carbon means better soil structure. Manure significantly increased total nitrogen compared to fertilizer treatments.
What are signs of over fertilizing?
Symptoms and signs of over-fertilization
- Crust of fertilizer on soil surface.
- Yellowing and wilting of lower leaves.
- Browning leaf tips and margins.
- Browned or blackened limp roots.

- Very slow or no growth.
- Death of seedlings.

Are fertilizers good or bad?
Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. However, applying excessive amounts of fertilizer leads to the release of harmful greenhouse gases into the atmosphere and the eutrophication of our waterways.
Why are fertilizers bad?
Chemical fertilizers have aided farmers in increasing crop production since the 1930’s. Some of the harm chemical fertilizers may cause include waterway pollution, chemical burn to crops, increased air pollution, acidification of the soil and mineral depletion of the soil.
What are the 3 main ingredients in fertilizer?
All fertilizer labels have three bold numbers. The first number is the amount of nitrogen (N), the second number is the amount of phosphate (P2O5) and the third number is the amount of potash (K2O). These three numbers represent the primary nutrients (nitrogen(N) – phosphorus(P) – potassium(K)).
How often should you apply fertilizer to your lawn?
While feeding your lawn once a year will improve its condition, feeding it 4 times a year will make it even healthier and more beautiful. Turn your lawn into the best on the block by putting it on this fertilizer schedule.
