Urea is the Urea is the lowest-cost form of granular nitrogen fertilizer available. It is the primary nitrogen component in most of our fertilizer blends and is also used on its own, when only nitrogen is required.

Ammonium Sulphate is primarily used as a source of sulfur in fertilizer blends. It is the most strongly acidifying nitrogen fertilizer and is often used as a nitrogen source on high pH soils.

Mono-ammonium phosphate is used as the phosphate source in blends. It can be used alone when a high level of supplemental phosphorous is required. 11-52-0 has a very low salt-index rating, making it very safe for seedlings and for placement with seed.

Muriate of Potash (potassium chloride) is the most economical source of potassium available. It is primarily used in blends on a wide range of crops.

An economical, low salt source of potassium. Popular for use on Horticulture crops, potatoes, and other salt sensitive crops.

Derived from naturally occurring sulphate of potash-magnesia, K-Mag Premium is the principal source of magnesium in our fertilizer blends. This high-quality low salt product is the preferred source of Magnesium on all crops.

A popular blend for forage grasses or crops requiring high levels of nitrogen with supplemental Sulphur.

Primarily used on forage grass and alfalfa-grass mixtures, this blend is effective for all crops in which only nitrogen and sulphur are required.

An ideal balanced blend for high nitrogen crops such as forage grass, corn, cereals, and soft fruit.

With nitrogen, phosphorous and potassium in a 1:1:1 ratio, it makes this blend one of the most popular and effective all-purpose fertilizers available.

This versatile blend is formulated for mixtures of grass and alfalfa. It has also become popular for field crops and tree fruit.

Traditionally used as a starter blend when no Potassium (k) is required.

One of our most popular all-purpose blends, used on everything from alfalfa to tree fruits. It is often used as a “starter” fertilizer when seeding or planting.

Often used on alfalfa and other crops requiring minimal nitrogen. It’s also used as an all-purpose blend whenever high levels of phosphorous and potassium are required.
