Time is passing to start enduring change.
We must start to create change.
Markets change – Our industry experienced
tremendous growth in the 90’s and first part of the 21st Century.
5 to 6 years ago, market began to flatten.
3 years ago, market began to dip.
Still a good market, with a huge exposure to retail
public.

A need to look outside the traditional box.
What worked last year, may not work next year.
This presentation is about looking outside the box at
some different ideas.

History – 40 years ago, government of Spain realized
it did not have enough land to grow food for its expanding population.
Faced with a decision, grow their own food, or import
it.
Tried a new approach, growing food in greenhouses.
After many failures, they came upon a formula that
works.
Location – Almeria is located on the southern coast of
Spain.
![Page 6: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/6.jpg)
Almeria, Spain
Greenhouse food production
27,000 Hectacres (67,500 acres) of greenhouse structures
Food production
Structures 37% flat roof52% sawtooth5% gutter connect

Greenhouse heating not necessary
Structures are simple, mostly covered with polyfilm.
![Page 8: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/8.jpg)
The formula that works.
NGS Technology (New Growing Systems)
NGS consists of 3 parts
1st
part – Multilevel Trough Technology
2nd
part –
Fertigation
3rd
part – Specialized fertilizer
These systems combined provide enormous harvest
rates per square foot of greenhouse.
1 acre of NGS is equal to 4.4 acres of growing in the
soil.
![Page 9: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/9.jpg)
NGS Technology uses 60 to 70 % less water.
NGS is simply defined as: The movement of water to
the right place at the right time in the right amount with the correct blend of fertilizers and nutrients.
NGS ‐
The main advantage of the NGS system over
other forms of hydroponics is that the plant roots are exposed to adequate supplies of water, oxygen and
nutrients. In all other forms of production there is a conflict between the supply of these requirements,
since excessive or deficient amounts of one results in an imbalance of one or both of the others.
![Page 10: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/10.jpg)
Savings are significant.
This is possible because plants are not in soil but a
nutrient rich solution that is constantly monitored by sophisticated software or by the growers experience.
These advancements allow this area to produce more
food in less acreage using less water.

![Page 12: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/12.jpg)
Ventilation –
natural airflow
Heating – few structures
![Page 13: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/13.jpg)
Multilevel Trough Technology (NGS)
Different sizes for different crops
Tri‐level tunnel
Second level membrane – very strong
The main advantage of multilevel trough technology
is that the plant roots are exposed to adequate supplies of water, oxygen and nutrients.
![Page 14: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/14.jpg)
Fertilizers
Vegetable oils as a nitrogen source
Humic acid & amino acids
Chemically sequestered micro nutrients
Non organic fertilizers are supplemented with urea
and ammonium sulfate.
![Page 15: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/15.jpg)
Fertigation
The proper mixing of nutrients in the correct amount
Monitored manually or with software
![Page 16: Spain Power Point Presentation](https://reader034.vdocuments.pub/reader034/viewer/2022042700/55746144d8b42a146f8b4887/html5/thumbnails/16.jpg)
Fertigation
Fertigation – more money is spent on this than on the
structures

Definition of Organic Crops
European standards
No application of pesticides and growth regulators
Use of natural fertilizers with conventional micronutrient supplements
European organic growing standards are less restrictive than those in the United States.

SUMMARY
Past 5 Years in USA
Changes in available water, labor and transportation
Changes force food production to decline in the traditional field production
Concerns of importing foods
NFT Technology in combination with co‐operatives and a dedicated banking system have made this area one of
the most productive areas in the world.
Could this be a possible emerging market?

Alternatives
Spanish government and growers have shown high
yield in crops grown in greenhouses with
Less labor
Reduced water usage
Less transportation costs with crops grown locally or
regionally
Fresher produce
