Fertilisers

Fritted Trace Elements

Back

Fritted trace elements are glass-based powders with specific mineral nutrients formulated into them.  Because they dissolve slowly, the nutrients are not flushed out rapidly by rain or irrigation water.  Using these products is a very good way of adding micronutrients to soils and other growing media.  The resultant residue, once the nutrients have been exhausted, is silica, in effect sand particles.

We currently have available three different formulations of fritted trace elements.  The percentage micronutrient contents of the three grades are shown in the table below:

All three products are packed in 350g packs.

Humate Rejuvenator

Back

Humate Rejuvenator is a mixture of granular Humate growth enhancer, Probiotic slow release organic based fertiliser and calcium in the ratio of 5: 4: 1.

The Probiotic fertiliser is derived from raisin stems, urea, alfalfa meal, rice bran and kelp meal.  It requires aerobic conditions to release its nutrients successfully.  Granular Humate is approximately 70% organic (humic and fulvic acids) and 30% inorganics.  Humate is a mild biostimulant and improves the functioning of plant systems as vitamins do in animals.  With Humate, plants make better use of nutrients and respond accordingly.

Liquid Nitrogen

Back

Our Liquid Nitrogen feed has an N:P:K of 28:0:0 w/w in which about 70% of the nitrogen is in a slow release form.  Typically one application will last 8 to 12 weeks.  It can be used both as a foliar feed and as a soil feed.  When used as a foliar spray, the leaves take on an attractive, darker, shiny, waxy appearance.  It is thus ideal for foliage plants. 

A good number of exhibition leek growers are now using it, but only as a foliar, right through to the end of the season.  Whilst it improves the colour and gives a nice sheen to the flags, there are reports that it also discourages such leaf pests as thrip from attacking the flags.  This may be because the darker colour repels pests.

Liquid Potassium

Back

Liquid Potassium has an N:P:K of 0:0:28 and it also contains 12½% liquid Humate.  The quality raw materials in the formulation produce not only a fully homogenised solution but a chelated solution resulting in the following features and benefits:

• 90% available to the plant
• stable at extremely high and low temperatures
• long shelf life
• non-toxic
• no chlorine salts or heavy metals
• no fluoride impurities

Liquid Potassium is an environmentally safe premium liquid nutrient.  It can be used on both soils and foliage.  It is ideal for bringing out improvements in flower colour and size.  With the Humate content, root density is increased.  It is ideal for hardening stems towards the end of the season, eg for bonsai and exhibition flowers in general.

Liquid Calcium

Back

This product was introduced during 1997 and was featured in an article on celery in the 17th / 23rd September 1997 issue of "Garden News".  There can be a requirement in many plants for increased calcium and a number of symptoms are indicative of a calcium shortage.  These include heart rot in celery, leaf tip browning in orchids and other plants, blossom-end rot in tomatoes and heat stress on turf.  Our Liquid Calcium is used primarily as a foliar spray for take-up of calcium into the leaf.  It is a fully organically chelated liquid calcium compound (trihydroxyglutarate complex).  As well as being used as a foliar feed, it can be used to increase the pH of low pH soils and to reduce the pH of high pH soils.  The usage rate for foliar treatment is one application at 15 to 30ml per 100m² and then 5 to 10ml per 100m² at 3 to 4 weekly intervals.

Ferticlin - Zeolite Slow Release Fertiliser

Back

Zeolites are a group of alumino-silicate minerals with a skeletal molecular structure, containing empty spaces occupied by various ions and molecules of water.  These have considerable freedom of movement that lead to properties of ion exchange and reversible dehydration.  The zeolite group includes more than 50 naturally occurring types and is the largest group within the silicates.

The zeolite we sell is a clinoptilolite, specifically a potassium form.  It is both an absorbent and adsorbent material; that is, it can take up or receive substances by chemical or molecular action as well as gather a substance on its surface in a condensed layer. Perhaps the most important property of zeolite is this high cation exchange capacity.  Zeolite products have many applications in various markets including horticulture and aquaculture.  In horticulture, most nutrients required by a plant are cations, eg potassium, magnesium, ammonium, calcium and trace elements.

Rape Seed Meal

Back

There is a requirement for certain growers, eg bonsai enthusiasts, for slow release organic fertilisers.  One of these is rape seed meal which has an approximate N:P:K of 5.9: 2.2:1.5.
