The seaweed extract in Maxicrop Natural Fertilisers stimulates beneficial soil microbes, which results in an
improved root system to take up more soil nutrients and water. Seaweed also helps to keep leaves greener, with
more chlorophyll, to improve the use of sunlight energy for carbohydrate production. Together with the balanced
natural fertiliser from plant extracts, this results in better, healthier growth, with ALL types of plants.
Our ‘All Purpose’ Organic Garden Natural Fertiliser (N-P-K 5-2-5) was launched in
2011 and has been very well received. This product provides balanced healthy
nutrition for ALL plants – and produces bumper crops of ‘grow your own’ fruit and
vegetables. We now have two further formulations – both made with the same
seaweed and plant extract raw materials.
Our Organic Tomato Natural Fertiliser is formulated with a higher level of potash
(N-P-K 4-2-6) for bumper yields of delicious healthy tomatoes. This formulation is also
ideal for other greenhouse crops and flowering plants.
Our Organic Lawn Natural Fertiliser is formulated to contain a blend of nutrients
ideal for healthy green lawns (N-P-K6-2-4). The seaweed extracts in Organic
Lawn Natural Fertiliser have been shown to make lawns more hard wearing – and to
help lawns cope better in dry conditions.

Maxicrop Natural Fertiliser is a 5:2:5 NPK liquid with added seaweed and plant extracts.
The product is suitable for use either as a foliar feed or it can be applied to the roots or
soil, as a drench. It is designed to supplement plant nutrition during the growing season
and can be safely used on a wide range of crops and plant types. Maxicrop Natural
Fertiliser is approved by the Soil Association for use in organic production systems.
In addition to providing a balanced level of nutrition, Maxicrop Natural Fertiliser also has the
added benefit of containing seaweed extract, which has various beneficial effects, including:
Stimulating beneficial soil microbes
Boosting root growth, development and health
Enhancing chlorophyll production and retention
Boosting the plant’s natural health mechanisms
Helping the plant to withstand and recover from
stress such as heat, cold, drought, wind damage, pest and disease attack, etc.

the growing season, resulting in top yields and quality for the grower.
Apply when enough leaf cover is available, at 10-14 day intervals or as
required. For use in knapsack sprayers, apply 125 mls in 10 litres of water.
Apply at 10-14 day intervals or as required.
Soil drench: apply 4.5 mls of product in 1 litre of water and apply to the
root zone at 10-14 day intervals or as required. Once diluted, use within
3 days and flush fertigation lines after use.
Product compatibility: To minimize the risk of potential compatibility
issues, Maxicrop Natural Fertiliser should not be tank mixed with trace
element products (e.g. Zn, Mn, Fe, Mg) . Due to the wide range of different
spray products available, it is impossible to test all combinations and
Maxicrop cannot accept any liability for any loss or damage. If in doubt,
Maxicrop recommend carrying out a bucket test to check compatibility.
Maxicrop Natural Fertiliser is available in boxes of 2 x 10 litre bottles.

New trials have confirmed the benefits of using seaweed extract based bio-stimulants to improve rooting and reduce stress in oilseed rape.
The most effective programme produced a 0.8t/ha (27%) yield response and a 0.2t/ha (16%) increase in total oil yield from autumn and spring use of Maxicrop Triple.
Based on oilseed rape at current farm values (£390/t) this yield improvement alone would be worth an extra £285/ha after the cost of treatment.
According to Maxicrop UK’s Mike Garner, while a range of factors are probably at play, the response is probably due to better rooting in difficult conditions and then the resultant improvement in spring and summer growth.
“Oilseed rape typically sets a very strong tap root, but is often slow to produce fine, secondary roots after emergence,” he says.
“This effect is often exacerbated in difficult autumns like 2011 and without these fibrous roots the plant’s ability to take up nutrients and moisture later on in the season is restricted.”
Mr Garner also points out that poor rooting often leads to poor establishment with poor ground cover, leaving the crop open to greater attack by pigeons and more susceptible to winter kill.
The independent trials - conducted by NDSM Ltd in 2011-12 - for the first time bolted on an autumn application at the 3-5 leaf stage of the crop to a tried and tested spring application commonly timed at stem extension.
This two pronged spray approach increased yield in the trial variety, Compass, grown on stress prone light land from 2.7 to 3.5t/ha.
While analyses of root or shoot biomass were not taken, measurements of boron in plant tissues confirmed better nutrient uptake potential of the Maxicrop Triple treated plants.
Levels in plant tissue in the spring ranged from 8-20% higher. “Treated crops were better able to scavenge more boron from the soil and effectively use it to fuel growth,” says Mr Garner.
“We have seen the benefits of a spring application of Maxicrop Triple in the past but this trial shows that the product can help improve early emergence and then maintain growth over a contrasting season.
“Fundamental research has shown that specific carbohydrates in our seaweed extracts serve as a source of food for beneficial and benign soil bacteria, resulting in a large increase in microbe numbers,” he points out.
“These microbes help improve nutrient turn-over leading to a significantly larger root mass and the increased bacterial population can also both physically exclude and compete with potential plant pathogenic soil fungi.
“In addition, soil and foliar application of Maxicrop Triple has been shown in University Research to result in greater maintenance of chlorophyll, leading to greener plants.
“This is, in part, due to a complex family of different betaines in the seaweed extract, which help reduce natural damage to the photosynthetic process.
“The practical benefits of these principle effects within the plant are to minimise some of the stresses imposed on the crop during key periods of growth and hence to keep the crop on course for high yields.
“Our advice to growers this year is to utilise Maxicrop Triple at 2-3l/ha both in the autumn and then in the spring, tank mixed with standard fungicides to counteract the varied stresses that curtail crop potential at these stages.
“While crops now have sufficient moisture to encourage early growth, many, particularly in the north, are drilled late and these will need all the help they can get to make up for the delay.”

Gardeners and growers could benefit from the
unique action of certain seaweed extracts in helping plants cope
better in dry conditions.
We believe the main reason that keen gardeners and commercial growers
in the UK use Maxicrop seaweed extract is for the stronger, healthier
growth that results from its use.
However, it has been shown that Maxicrop can also helps plants
cope better with stress – including drought stress. Maxicrop
works by improving the efficiency of uptake of water from the soil
and by allowing plants to cope better physiologically with drought
Improving the efficiency of uptake of water from the soil
Regular use of Maxicrop increases root mass and rooting depth –
from seedlings to mature plants – see Figure
1. The greater the root mass and depth, the greater the potential
to take up available water from the soil.
Researchers at the University of Wales recorded a near trebling
of root weight with perennial ryegrass after five weeks following
use of Maxicrop - they concluded that: "The ability of Maxicrop
to improve root development gives the plant a greater potential
to increase nutrient uptake. Similarly, under field conditions,
an increased resistance to water stress could be expected from a
more extensive root system."
More and deeper plant roots will tend to give better soil structure
- allowing rainwater to enter and penetrate the soil better, with
less run off.
Allowing plants to cope better physiologically with drought
Some naturally occurring substances in seaweed - such as mannitol
and betaines - are known to enable plants to cope better physiologically
with drought stress.
These substances work as 'osmoprotectants' in plants - increasing
the ability of the plant cells to maintain an internal cell solute
concentration when the external solute concentration is high - enabling
plants to function better in drought conditions - see
Will Maxicrop cure a severe drought problem?
Absolutely not! - but it can help the situation as described above,
as part of an overall package of measure that gardeners can employ
- such as water conservation (water butts, etc.) using dish or bath
water, watering early morning or late evening (to reduce evaporation)
mulching (to hold moisture) etc.
However, if plants don't get enough water they will not 'do' -
Maxicrop will help, but it is not a miracle cure for drought!
Which product and how much?
We recommend mixing 45ml of Maxicrop Original seaweed extract in
9 litres of water (typical watering can full) - this solution can
be applied as a root drench or foliar spray every 7 to 14 days (every
7 days in hot, dry weather). Watering cans or knapsack sprayers
can be used to apply the solution.
Although positive effects on root growth start to occur after just
two applications, it is important to apply regularly to get the
Applied in this way, a litre bottle of Maxicrop Original (costing
£8.29) will be sufficient for a garden of 140 sq.m. (assuming
the whole garden is fed for a 3 month period).
Maxicrop Original contains negligible quantities of N P K fertiliser
and so tends to be used by gardeners who already use some sort of
fertiliser mix. Maxicrop Complete Garden Feed has all the advantages
of Maxicrop seaweed with the added benefit of 5:5:5 NPK fertiliser.
The benefits of Maxicrop in normal/non drought situations (better
rooting, greener leaves, stronger healthier growth) make it excellent
value for money - helping as part of a package of measures to cope
with drought conditions is an added benefit.
