Why elemental sulphur is an apple, not an orange, when comparing sulphur sources.

Sulphur is an essential mineral nutrient. It is required to help support growth and development of strong, healthy plants. Elemental sulphur is the apple to the sulphate sulphur orange. All S sources are not created equally and require different management and application considerations.

Elemental Sulphur – broadcast and forget.

 Elemental sulphur must be broken down in the soil through biological processes to convert to sulphate sulphur – the form plants can easily take up for use. With a variety of particle sizes, the conversion rate of elemental sulphur is both immediate, and long term. A single application of elemental sulphur can provide benefits for three or four subsequent crop years. Broadcast in spring or fall, elemental sulphur is a valuable source to establish a sulphur supply within the soil to prevent soil S deficiency.

Sulphate Sulphur – apply yearly with soil amendments.

Sulphate sulphur is applied with a Nitrogen source. Yes, it is immediately available to plants, but it can also be lost during rainfall or over-wintering. Because it offers uniform particle size, it doesn’t provide long-term benefits in the soil. Water soluable, and quick acting, sulphate sulphur must be applied each year to establish ideal sulphur levels and prevent sulphur soil deficiency.

How do you choose which sulphur source is right for you?

Many crops, such as canola, require high levels of S to reach their potential. An elemental sulphur source, such as Bio-Cycle BioSul Premium Plus, combines elemental sulphur with a compost mix that delivers macro-nutrients to start breaking down elemental sulphur immediately. And with a variety of particle sizes, it provides season-long, and long-term soil benefits, from just a single application.
