A New Direction in Foliar Calcium Delivery

Opti-Cal is a foliar calcium delivery product which moves calcium in a completely new direction. Opti-Cal uses a collection of technical advancements to deliver a foliar calcium that works on the leaf like no other calcium fertiliser.

Opti-Cal contains a unique MAS calcium package plus the natural organic chemistry of its Bio-Chel chelation; these synergistically work together to optimise leaf acceptance of calcium.

Organically chelated Calcium & Iron

Bio-Chel is a range of water soluble and liquid nutrients which are chelated by a unique soluble lignin complex developed from Engage Agro’s MAS™ programme.

Bio-Chel’s nutrient chelation is derived from one of nature’s most renewable resources – trees. They meet all the requirements of sustainable agriculture and offer growers an efficient source of ‘naturally’ chelated nutrients for foliar and root application.

Bio-Chel nutrients naturally contain surface active polymers which ensure even distribution and penetration on the leaf surface without the need for additional adjuvants. Also being organically derived, they are highly versatile, efficacious and very safe to use.

Bio-Chel Ca

Crops: Cereals, vegetables, citrus, salad vegetables, fruit and ornamentals.

Use: Bio-Chel Ca is a multi-function calcium, providing growers and farmers with a new source of available calcium for both root and foliar application. The ratio of lignin to soluble micronutrient within Bio-Chel Ca has been optimised to ensure full chelate complex stability over a pH range of 4-9, providing high availability through the optimum pH range for fruit and vegetables, and their growing systems . Bio-Chel Ca is a blend of modified lignin calcium and calcium formate and works as a chelated calcium source and complexing agent for soil nutrients helping to maintain soil nutrients in forms that are more available to the plant.

Bio-Chel Fe

Crops: Cereals, vegetables, citrus, salad vegetables, fruit and ornamentals.

Use: Bio-Chel Fe is an advanced micronutrient chelated by a unique soluble lignin providing growers with a new source of iron for both root and foliar application. The ratio of soluble lignin to iron in Bio-Chel Fe has been optimised to ensure full stability and availability over a pH range of 2-9. Bio-Chel Fe is easy to use, non-phytotoxic and provides high levels of soluble and complexed iron when used in foliar and / or fertigation systems. Engage Bio-Chel Fe powder is an excellent choice for dry mixing with fertilisers.



Bio- Chel Initiate

Crops: Cereals, vegetables, citrus, salad vegetables, fruit and ornamentals.

Use: Bio-Chel Initiate is a multi-function liquid lignin complex, providing growers and farmers with a new source of organic biostimulant to aid the establishment of plants and crops in both soils and substrate by rapidly generating a healthy and energetic rootzone. Bio-Chel Initiate binds plant growth, promoting the auxin response for enhanced root growth and activity. Bio-Chel Initiate works as a complexing agent for root applied nutrients and maintains them in forms that are available to the plant . It is also a source of metabolisable energy for the soil microbes present in the rhizosphere. It will provide a source of available calcium, a necessary requirement for healthy growth. Bio-Chel Initiate improves fertiliser efficiency and decreases rootzone salinity while also enhancing crop vigour, growth and quality.
