Field Lettuce

In a competitive market achieving optimal quality of lettuce is the key to success. Whether it is to maximise weight and uniformity or to support the important processes which underpin crop health, or limit the damage from harmful, growth restricting stresses.

Timing nutrients and ensuring there is optimal supply through key growth processes will ensure lettuce crops are supported through periods of peak demand and during periods of elevated stress, whether it be abiotic pressure through adverse growing conditions or biotic pressure from pests or pathogens.
Engage has over a decade of experience in lettuce nutrition across the world and has developed a number of innovative products aimed at targeting key periods to keep crops healthy, so growth is of the highest quality.

This highlights products that will aid growers in growing quality lettuce, maximising a plants genetic potential and circumventing loss through stress to ultimately assist in uniform growth, optimising quality and minimising wastage.

Fortify Cu

Fortify Cu (7-16-0+1.5% Cu) is a unique formulation of nitrogen phosphorus, copper and halide ions which complement each other to support plant growth, support crop health and reduce yield loss. With programmed application Fortify Cu will aid vascular flow, support root growth, maintain established yield and reduce susceptibility to disease infection.

Aqualatus (also known as Integrate) is a unique soil surfactant with outstanding qualities to benefit soil nutrition. Its formula, unique to Engage, makes it essential for the maximum distribution of root applied nutrients to aid root functions and nutrient uptake.

Most importantly regular use of Aqualatus will slow the natural gravitational movement of water and nutrients including nitrates, so will reduce the overall requirement for soil grown crops. In trials this level has been proven to be up to 50% without any loss of crop development, yield and quality.

VerdeNT is a unique nitrogen and calcium formulation combined with Arm U advanced and MAS technologies specifically designed to manage crop structure to enhance yield and quality. The nitrogen within VerdeNT is slow released by the Arm U advanced technology which for foliar use means the nitrogen is absorbed as amine which makes its use by lettuce very different. Unlike nitrate nitrogen foliar fertiliser VerdeNT does not stimulate auxin production which promotes softer growth and diverts calcium away from developing heads. Growth is more compact and stronger, calcium is used more efficiently to enhance leaf and head strength, leaf thickness and higher quality growth.

Bio-Chel Ca

The worlds most concentrated calcium chelate, Bio-Chel Ca is completely organically formulated from a sustainable, renewable resource and is 100% pure available calcium.
Being 100% calcium and organic means its acceptance by plants could not be higher so application efficacy is ensured. Also due to the strong organic chelation of Bio-Chel Ca is non-reactive making is ideal for application within all nutrient and foliar plant protection products.

Bio-Chel contains natural surface active compounds which breakdown surface tension of water allowing even distribution across the leaf surface removing the need for adjuvants in sprays where Bio-Chel Ca is used.

The overuse of inorganic fertilisers and pesticides has massively reduced soil biology to the point where the need for silicon nutrition has established. Plants only take up one specific form of silicon which is silicic acid. Engage developed the use of a new form of stabilised silicic acid and this is Sion.

At 21% Silicon, Sion is highest available liquid silicon in the world and delivers silicon at such high levels its use rate is only required 0.25-1.0L per hectare. In lettuce using Sion regularly will support the optimal growth to strengthen all plant tissues to reduce susceptibility to any stress and redcue susceptability from pathogen infection and insect predation.

Sentinel is a 10% targeted foliar Silicon is based upon the delivery of mono-silicic and salicylic acid to the crop. This is the only form of silicon plants will accept and its affects are highly beneficial to lettuce crops. Once applied it is used by the plants help to build resilient cells which act as a physical barrier for the crop to help reduce both susceptibility to disease infection and predation from insect pests.

Cypher is a modified organic acid blend derived from plant active portions of lignin and leonhardite ore. It comprises of 100% organic acids which unlock nutrient potential for increased lettuce crop growth and yield. Cypher is designed to condition soils which have become compacted or overloaded in bonded salts.

Regular use of Cypher will help maintain good aggregate stability, strong biomass and active soil microflora and will be-bond ‘locked up’ nutrients like calcium and phosphorus to ensure herb crops can uptake important elements at higher levels.
