2. 1- calculation
soil weight of every basin dimension
every acre have 1000000 KG of soil as 15CM deapth
basin dimension 120/120 CM
acre basin
4200 1.2 M
10000000 285.7 KG
every 5KG soil need 1.3 of water (FC)
5 KG 1.3 L
286 KG 75.4 L
every 5KG soil need 1.3 KG compost as a treatment
5KG 1.3KG compost
286KG 75.4KG compost
every 15KG soil need 0.05 gm of yeast as 5% ( saccharomyces)
15KG 0.05 yeast
286KG 95 gm yeast

3. Design &
Implementation
1- 30/10/2019 : We prepared soil in one basin
and planed papper seeds
2- 9/10/2019 : we irigatted the soil as a soil FC
3- 13/11/2019 : we prepared another 3 basins of
soil and planted roccer seeds
- one for compost treatment
- one for yeast as a biofertlization
- one as controller
4- 18/11/2019 : we bought vermicompost and
soak it in water
(As 1KG vermicompst for every 10L water *1:10* )
5- 23/11/2019 : we added vermi tea /we activated
Saccharomyces as an active yeast
6- 27/11/2019 : we irrigated the sail just all
7- 4/12/2019 : we irrigated the sail just all
8- 7/12/2019 : we gain all roccer from all the
basins

4. Compost & yeast treatment
18NOV 2019
We soaked 8KG of vermicompost in 80L of water
as 1:10 vermi for wter then we let them for 5
days to solute vermi in water
23 NOV 2019
We added the vermi tea to the first basin of soil
23 NOV 2019
We activate 95 gm of yeast by alittle of
molasses and warm water then we let it in
dark warm place to be activate
After that we added it to thirt basin of soil

The basin that we added vermi compst to it :
plants are so healthy and growth fastly as before
Control basin : stil the same and the growth was
weak with simply plants
The basin which we added yeast to it : plants
healthy was better than befor a lot and the
plants was healthy and plants growth was so
well
( No molds or infections )

6. conclusions

weight 2.96 gm– white small bag weight 2gm )
Papper not Sprouted because of
something wrong with seeds vitality
Vermi compost basin was the best
treatment
Total weight for compost basin =
676.83 gm
Total weight for control basin = 317.39
Total weight for yeast basin = 512.9 gm

Vermi compost
About 2300 years back a great man named
Aristotle named Earthworms as intestines of the soil. And after nearly
2300 years his words gained prominence and the solution namely
"VERMI-COMPOSTING" came in to picture given its viability, cost
effective nature, and the eco-friendly way of disposing the waste.
Vermi composting a biological process which involves the
interaction between earthworms and micro-organisms leading to the
formation of earthworm biomass and the vermicompost
Vermicomposting is also a biooxidation
and stabilization process of organic material
the organic waste is known to contain 120 virus and bacteria which
are harmful to human beings. The compost reduces 75% of the disease
causing pathogens. Apart from increasing the nutrients the compost
also increases the physical structure of the soil and the water holding
capacity
Enzymatic bioremediation of soils: use of vermicompost as a source of pesticide detoxifying enzymes
Vermicompost is an ideal organic manure for better growth and yield of many plants. It can increase the production of crops
and prevent them from harmful pests without polluting the environment
A number of bacteria of different species have been reported by different workers in vermicomposts produced by different
species of earthworm like Pseudomonas oxalaticus in Pherentima sp., Rhizobium japonicum and Pseudomonas putida in
Lumbricus rubellus, Azospirillum, Azobacter, Nitrobacters, Nitrosomonas, Ammonifying bacteria and phosphate solubilizers
in Eudrilus sp.

8. Vermi compost
Vermicompost has higher nutritional value than traditional composts. This is due to increased rate of
mineralization and degree of humification by the action of earthworms
Vermicompost has high porosity, aeration, drainage, and water-holding capacity
Presence of microbiota particularly fungi, bacteria and actinomycetes makes it suitable for plant growth
Nutrients such as nitrates, phosphates, and exchangeable calcium and soluble potassium in plant-available
forms are present in vermicompost
Plant growth regulators and other plant growth influencing materials produced by microorganisms are also
present in vermicompost Production of cytokinins and auxins was found in organic wastes that were
processed by earthworms
Earthworms release certain metabolites, such as vitamin B, vitamin D and similar substances into the soil
In addition to increased N availability, C, P, K, Ca and Mg availability in the casts are fou
It was found that there was a significant increase in growth and yield parameters like leaf area, plant shoot
biomass, number of flowers, number of plant runners and marketable fruits weight by the applications of
vermicomposts as compared to inorganic fertilizers. Authors speculated that growth responses were due to
the ability of humic acids present in vermicompost to act as plant growth regulators or because the humates
may have absorbed hormonal plant growth regulators

9. Yeast
• sacchromyces helps to root to absorb some mineral
from the soil it also adsorb some menirals
• By the way sacchromyces solube protenes in leaves
and significant accumlation for pro;ine , solube sugers
and total phenolic compounds , more over anti toxins
enzymes , poliphenol oxides (PPO) ,peroxides (POP),
and phenylalanine ammonia – layse
sacchromyces is one group of
many groups of the yeasts
When we add it to soil it can
acctivate most of the soil
microbiologys “free and
symbiotic micobes)
That have postive result in the soil
Analyses N, P for roots and soil
It also anyses strach to simple
suger that can be avalible for the
roots to absorb it and be avalible
for the plant

10. Yeast • It helps the plant to Resistant stress and helpes the plant
to control of closing and opening of gaps
• According to work as a biocombat from bactria …….
• It makes some chemical reactions of heat – chasing that
can warm the leaves to restistant Frost from some plants
• It also makes some chemical reactions absorb the heat that
helps the plant to resistant the warm atmosphere and the
hot sun
• It also performs chemical reactions that reduce the effect
of fertilizers and pesticides on the leaves
• Helps reduce fertilizer and chemical pesticides that damegs
the plants and our helth
According it can activate the symbiotic
bactria than growes on the Legumes
roots that can avalib many mineral for
the plant
It also works as a biocombat for more
of another bactria and Fungus
This findings support the nation that
brewer's yeast is a cost – effective bio
fertilize
Saccharomyces have a postive effictive
on the plant leavs too
“solube protenes in leaves and
significant accumlation for pro;ine ,
solube sugers and total phenolic
compounds , more over anti toxins
enzymes , poliphenol oxides (PPO)
,peroxides (POP), and phenylalanine
ammonia – layse”

11. Yeast in soil
Activate all helpful microbes in soil
Provide many things in soil like
47% protines
8%minerals
Nuclic acides and lipied
Micro nutrents and macro
Vitamens
Protect plants from damegnes
microbes
Help plants to resetant stress
Help soil microbilogys to recycle
nutrents,creat humes and anyse strach
to simple suger
Feed and activate nitrigen fixers
It is like a biocombat
Help roots for absorbation and
adsorbations
