What is nitrogen fertiliser?

June 29, 2023

Nitrogen fertiliser is a type of fertiliser that is specifically formulated to supply plants with nitrogen, which is a primary component necessary for their growth. It can come in the form of synthetic fertilisers, such as ammonium nitrate and urea, or organic fertilisers like manure and compost.


Some of the key benefits of nitrogen fertiliser include:

  • Improved soil structure
  • Increased water-holding capacity
  • Better nutrient availability
  • Enhanced disease resistance in plants.


Additionally, nitrogen fertiliser helps prevent nutrient leaching from the soil by providing a steady source of nutrients to crops throughout the growing season.


However, there are considerations to keep in mind when using nitrogen fertiliser. One downside is its potential to leach into groundwater or nearby water bodies if not used correctly, since excessive nitrogen runoff can lead to water pollution and harm aquatic ecosystems. Therefore, it is important to apply nitrogen fertilisers responsibly and follow recommended application rates. To learn more about nitrogen fertilisers and their best application methods, make sure to talk to the garden experts at Narellan Sand, Soil & Garden Supplies for reliable information as well as to buy the fertilisers you need today.

Additional FAQs

  • What is the downside of nitrogen fertiliser?

    One downside of nitrogen fertiliser is its potential to leach into water bodies and cause water pollution if not used responsibly. Excessive nitrogen runoff can harm aquatic ecosystems.

  • Can you use too much nitrogen fertiliser?

    Yes, using too much nitrogen fertiliser can lead to nutrient imbalances, nutrient deficiencies or toxicities in plants, and excessive vegetative growth at the expense of flowering and fruiting.

  • Is nitrogen fertiliser good for plants?

    Yes, nitrogen fertiliser is beneficial for plants as it provides them with an essential nutrient necessary for growth, protein synthesis, chlorophyll production, and overall plant health.

  • What are the symptoms of nitrogen deficiency in plants?

    Symptoms of nitrogen deficiency in plants include stunted growth, yellowing of older leaves (chlorosis), reduced leaf size, and overall pale or dull appearance.
