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.
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.
