Objective –
Current agriculture in Japan, there are various problems like soil gotten worse because of the use of pesticides (soil disinfecting, insecticide), growth of outlays and residual pesticides.
In this experiment, we will prevent these problems and try to intend developing technologies of future-oriented agriculture that are safe and hassle-free.
As the results of this experiment, we expect the increase of key-fruit numbers, growth promotion, progress of fruit composition (rise of sugar content), progress of disease resistance of plant body because of its bloated depth of leaves and around of stems. If we could get these results, we expect the increase of crop yields.
And from the developed technology, we hope for the cost reduction, rise in revenues, and attendant stabilization of agriculture.
Experiment location
193-2 Azaakuto, Ooazanakano, Ishikawa-cho, Ishikawa-gun, Hukushima-ken
Chemical-free tomato producer
size of the house 70*72m2
materials and methods
With using negative ion plate, we will negative ionize the air in the house.
in the half size of the house 35*72m2, 265 of it have set
put them in every 50cm
shower mineral water once every week (the mount mineral water to shower: 300L(for an hour))
The mount of ion
Without magnet plus:2710 minus:480
With magnet plus:7740 minus:2350
Measurement item
tempareture: everyday
humidity: everyday
crop yields: every picking season
negative ion area, controlled air area, air ion measurement: once in every two weeks
questionnaire of planter : once every three days
experimental period
starting date of the experiment: May 22nd- August 31st
ratio1:increase of crop yields(weight)
total crop yields mount of negative ion is three times of that of controlled one
Large fruit about 7times
Medium fruit about 4.2times
The affects of the increase of its number and fruit enlargement from negative ion farming methods
Ratio.1 prospect of the increase of earningsd
Increase in proportion to the fruits of negative ion area
The earning have increased about three times
the daily average of the earning prospect
negative ion area 41,744
controlled area 13,492
earning estimation in one month
monthly earning difference 847,560
extremely small 30yen small 50yen does not deal in the agricultural cooperative
Middle, large, extra large mixed in one bag (800g) 500yen
(middle size 25yen large size 50yen agricultural cooperative price)
Reference picture
Negative ion plate set PVC greenhouse
Negative ion plate (with magnet)
When you compare these two area, negative ion area has less damage of louse-borne disease
It is obvious that there is better progress in negative ion area
Controlled area Negative ion area
Controlled area Negative ion area
consideration
There were weak progress in the plant, and on the other hand, there were remarkable progress in its fruits. So, it will be estimated that there were no intense progress in simplicial plant, but there were the negative ion affect in leaving seeds for fructifying the fruits that is good quality.
There were remarkably low damages to the condition of the plant body in negative ion area compared to that of controlled area right after the progress of disease damage.
However, as disease damage go along, damage situation got similar in the both of the area.
Which means the effect of negative ion, especially, the effect of mineral water lead to increase crop yields, but it would be estimated that there were less effect to prevent disease and insect damages.
It would be thought that the mineral water effect only reflected to the number of its fruits as it was hard to foliar spray sufficient mineral water because of the water reducing farming methods
Though there might be some effects on it, if there is no established usage, it means that technology cant be used realistically. So, we need to have the established usage along the varieties of agricultural crops, farming methods, and weather
