BASIC PRINCIPALS OF NATUECO FARMING.

BASIC PRINCIPALS OF NATUECO FARMING.

[1] HARVESTING THE SUN.
In all biological processes, energy input is required and solar energy is the only source available. No time and no square foot of sun energy should be lost by not harvesting it biologically. Lost sun energy is lost forever.
Photosynthesis is the main process by which Solar Energy is absorbed. It is therefore objective to obtain higher photosynthesis degree. Although genetically photosynthesis efficiency is around 1 .1/2 percentage to 2.1/2%, we can increase leaf index [area of leaf for every square meter of land], use of multiple canopy utilizing direct and filtered sunrays etc.

[2] FIVE STAGES IN A PLANT LIFE.
Every plant goes through five stages in its life: [1] Childhood [2] Puberty [3] Youth [4] Maturity and [5] Old age. These stages are of roughly equal duration and external intervention at proper stage only is most effective.
e.g. There is no use giving fertilizer dose when the plant has become old and is dying.
Generally, plants can be classified as seasonal short duration life span [90 to 130 days], Medium life span of 4 – 5 years and perennials or long life span. For short duration life span, all 5 stages become very critical. For example if sumptuous roots are not developed in the first 15to20 days [20%.of lifespan] no amount of external inputs, thereafter will be useful/effective.
Leaves and Branches also show these stages in their life cycles. Yellow old leaves can only fall they cannot be rejuvenated. In addition, old branches become deadwood eventually.

[3] MEDIUM FOR ROOT ZONE.
Generally, this is soil. However, one can do without it as in the case of hydroponics.
The main purpose of the medium is
[a] To give support to the plant and anchoring it by means of shoot root and feeder roots.
[b] To supply nutrients to the feeder roots. [c] To provide moisture to the plant roots.
[d] To provide good air circulation to the roots.
It is always possible to prepare an ideal soil by human intervention. The soil also supports a whole range of microorganisms up to earthworms. The presence of this microorganism is so very beneficial to the plant roots in that they convert minerals found in nature into root absorbable forms.

[4] PLANTS MANUFACTURE THEIR OWN FOOD
Unlike animals, plants manufacture their own food. By means of photosynthesis, water and carbon dioxide, plants produce sugar – glucose, which are then converted to other forms of sugar, lignin, fats etc. Plants produce 3 – 4 Gms. of dry mass/ square foot of photosynthesis area / per one sun-day of 8 – 10 hrs / day.
From this: - [a] 1 gm is used in plant metabolism.
[b] 1gm is used to build plant body, roots, stem, leaves etc.
[c] 1 gm is either stored or is used for producing fruits.
It is very useful and instructive to know especially about the timings and places of storage of food/ energy and how to tap them at appropriate time. Without the knowledge of this the enzymes and hormones [Gyberalic acid, Indol acetic acid] one may end up in having plants with luxurious growth but scarce fruiting.

[5] PLANT BIOCHEMISTRY.
As mentioned above hormones are the messenger and enzymes the catalysts for plant metabolism, and their study is very useful for general understanding of plant physiology.

[6] A tree is like a colony of independent branches, which have their own life cycle.

[7] It is possible to create a microclimate for 10 Guntha.
