Health, Nutrition and Preventative Medicine through Permanent Agriculture

Sustainable Agriculture London

We are looking for a new home for our headquarters. Due to our current rented farm being sold to developers we only have a limited time at our present location. After eight years here we are looking for a generous donation from one of our supporters. This 6 acre farm near St. Albans will be perfect for continuing our demonstration, gardening therapy and training work for the UK public on a larger scale than our existing 2 acre farm in the village of Shenley. The buildings there are also ideal. Suitable refurbishment to convert the out buildings to an holistic care centre will facilitate a collaboration with another charitable trust (the VediCare Charitable Trust) and a training centre for sustainable growing technology can be set up. By teaching how to replenish local soils for local people we can put back the nutrition into food crops, and continue our valuable and therapeutic work for people and the children of the UK who may have impaired mental health and for people who just wish to boost their immune system. The cost is £1,883,465

One big feature of Sustainable Agriculture or organic farming is that it should know how to grow pest and disease free crops without the use of chemicals. Good Gardeners International is a charitable organisation (originally founded in 1962) and is our mother organisation and can receive donations (above) to fund this very cause for all our APPEALS listed on The Good Gardeners website

BBC WORLD NEWS of 17th January 2019

It is now the opinion of international experts that 11 million lives could be saved every year if we cut our consumption of meat and double our consumption of fruit and veg.

 We currently have over 60,000 hits between this web site and Good Gardeners International web site. This shows there is a big move to help save the planet with Sustainable Agriculture (which is naturally organic). This will  help us teach these principles and to train NGO staff and prospective sustainable agricultural practitioners all over the world. Sustainable Agriculture means you can deal with all your own organic waste and turn it into fertiliser. IE., from towns, Villages and Schools etc., and thus solve all your waste management and agricultural problems of pests and diseases locally, at the same time. This aspect of sustainable agriculture is much overlooked today and thus these wastes cause major pollution problems in different parts of the world. 

WHAT WE DO – Prevent Pests and Disease

We have international solutions for most of the common problems concerning pests and diseases in modern day agriculture/horticulture. see our archives section for the latest updates.

Our latest revelation is that we have cured black spot in Roses with our HH-4 product. You only need to spread the end product 1 inch (25 mm) thick around the root zone of rose plants in the autumn, and then a second dressing before flowering and possibly a third dressing in the winter again if the problem persists.  NOTE There is no other cure for this condition with an organic product from any individual or any company.

The HH-2 system

The HH-2 system of growing is easier and a lot simpler than  ‘Bio Intensive farming’, and ‘the double digging method’ and the ‘Biodynamic’ system. It is more scientific than esoteric. The HH-2 horticultural/agricultural system shows how less machinery is needed and thus less fuel. Not only this, but our research shows over a 22 year period that increased profits can also be easily achieved because the end product has such a high value. This is not a new science but rather is the result of the work of the great Sir Albert Howard MA., CIE., etc., combined with the other sciences that have been brought in by Richard Higgins – inventor and founder of this web site.

A comparative study by Rodale Institute is made between conventional systems and organic systems. But we can increase on these standard organic systems with the Howard-Higgins system which starts at the most basic level of agriculture/horticulture which is the micro organic level. We proliferate these organisms, namely fungi and bacteria, and introduce them into any soil type with the HH-2 system. Thus the soil will become instantly more fertile and will be able to support much higher densities of cropping. The economy is that you do not need to apply HH-4 every year once you have achieved the minimum standard of fertility.


We teach zero till and low till systems for horticulture and agriculture. The Good Gardeners have been practising no dig gardening for 50 years. This makes farming and gardening a whole lot easier. Together with two other sciences we now have a complete package to take sustainable farming and gardening into the 21st Century. No chemicals are needed in this system; organic or synthetic.


Indeed our surveys in Africa reveal that with this technology we can take children off the fields and put them back in school as far less work is required to grow increased harvests. You can help our work here by donating to the Good Gardeners charity.

The optimum fertiliser/soil conditioner, we have developed, known as HH-4 is complete in its quick and slow release properties. It is a plant medicine, a tree medicine and second to none in disease prevention. Anyone who purchases the HH-2 system will be able to produce this reliable and consistent end product HH-4 themselves.  John Innis Labs inspected HH-4 and stated that we have manufactured fertile top soil – something that takes Nature between 500 – 1,000 years to produce.

Consultants to the Industry

We are consultants for the regeneration of exhausted agricultural land and marginal land. Both these types of land can be brought into full production within one season with the HH-2 technology. With crops ranging from vines to  vegetables we are able to greatly increase crop production with pest and disease free capabilities.

By operating the HH-2 system correctly we can solve many of the problems in agriculture today.

By solving the problems of Pests and Diseases in the Farming World we can completely avoid the use and production of all types of chemicals, herbicides, pesticides and fungicides. All these and the CO2 emitting methods of producing them become completely unnecessary.


Like no other manufactured system

For small scale operators our HH-2 superfast Composter units are ideal – with No moving parts – and No electrical hook up. They are self convecting and self condensing and proliferate the right type of fungi and bacteria for the manufacture of a consistent and reliable fertiliser/soil conditioner in one. One pair of HH-2 can produce 8 tons of finished HH-4 per year in the temperate climate and 12 tons a year in the tropical and subtropical regions of the world. It is the design of HH-2 and the management process that is so effective. 


The HH-2 facilitates the right fungi and bacteria

WE CULTURE SPECIFIC FUNGI AND BACTERIA TO PROLIFERATE OVER A SPECIFIC TIME FRAME -This renders all manner of wastes into perfect worm food with a carbon to nitrogen ratio of 10:1 and in conjunction with biochar and rock dust you can easily make this optimum fertiliser/soil conditioner known as HH-4.   The basis of this work was Albert Howard, the great agricultural pioneer who observed that the fertile forest floor was at the outset in the region of a 10:1 carbon to nitrogen ratio. Thus this was the basis of his research that enabled him to produce such an effective natural fertiliser and soil conditioner. Higgins, today, has pulled together three sciences that have evoked the Howard-Higgins Horticultural System.

This material HH-4 prevents pests and disease in all types of growing systems

Solve pests, disease and all your waste management problems at once with the HH-2 Horticultural System


The results are that all types of pests and disease will be reduced to an absolute minimum, meaning no slugs, snails or caterpillars, no aphids etc., eating your crops. This applies to the temperate, tropical and sub tropical zones. This has proven to be of great interest to the RHS’s head gardeners and assistants at Wisley and to the National Trust, Rothamsted, Niab, Wellsbourne Horticulrural Research International and to many Universities around the world.

A) Agriculture/Horticulture

With over 20 years of research,  we are able:

TO CONDITION ANY SOIL TYPE – WITHOUT ANY KIND OF SOIL ANALYSIS    to produce healthy and abundant crops in one season. This is a remarkable breakthrough in Agricultural technology.                                                                                                                         TESTED IN THE UK, FRANCE, INDIA AND AFRICA. 

 “FRESH HUMUS”  (HH-4) HOLDS 20 TIMES ITS OWN WEIGHT IN WATER. (Oxford Real Farming Conference) Thus it is what is needed in modern day agriculture, what with climate change and increasing incidents of drought.         

PV smiling face

the happiness of free fertiliser

even the potato blight phytophthora infestans, which is an airborne blight, is done away with with the HH-2 technology.

For small scale operations we are suppliers of the HHI wheel hoe. By operating this simple tool weeding becomes a hundred times faster than by hand hoeing.

please see our products page 

B) Health

Your soil will become continually micro-organically active and crops grown in this soil will contain fully synthesised protein rendering the crops unattractive to pests and disease. The health giving properties of food grown in this way is vastly increased as it contains much more minerals, vitamins and proteins and with many more times the anti oxidants than conventionally grown food.

Crop yields are increased and the attributes of disease resistance are passed on to the consumer; forming a stronger immune system for both animal and man.

We exemplify our work for schools, colleges and Universities to expound these principles into farming today. Also for NGO’s and their training staff, such as CRS., OXFAM, UNICEF, WORLD VISION, SAVE THE CHILDREN and NORGESVEL, etc., who may wish to take this work to the rest of the world.

The land at our Well End Micro-farm has not previously been ploughed for 45 years and and no expense of heavy mechanical subsoil treatment. We have employed deep rooting plants to crack the subsoil pan. Food grown in this way with the Zero Till/Low Till methods is much higher in minerals, vitamins and proteins and is ten times higher in anti-oxidants. And is therefore considered the fastest/safest route to Preventative Medicine (Howard).

This is the original science of Sir Albert Howard. Now reformulated

surface water drainage

with the conclusive research of both Sustainable Agriculture London and The Good Gardeners charity, the Director, Richard Higgins has moved this work into international status and is now appealing for help to take this work to the needy peoples of the world.

Please see our appeals on the web site  charity
Surface water control/drainage is essential for times of heavy rainfall, thus the plants can keep growing, unhindered, in all weather conditions.

All types of modern sustainable agricultural practises would benefit from the principles that we teach. These are missing in mainstream agriculture today the world over.  They will play a large part in food security and disease prevention in crops and animals in the future.

 If you wish to support our cause please donate to GGI stating what area of our work you would like to support. It is of the utmost importance that this science coming from the work of the great Sir Albert Howard CIE., MA., etc.,  who is now considered the Grandfather of organic farming, becomes available to the general public and the world-wide farming community.
