In the case of composting of fallen leaves and weeds, the problem is the adjustment of the moisture content, air permeability is not so problem.
While compost moisture increases about 25 cm from the surface in tropical squall, however decomposition of inside compost does not proceed too dry by evaporation due to the temperature rise
To raise the temperature by adjusting the balance of heat dissipation and heat generation to increase the compost pile in except summer in Japan, the temperature rise is not important in Sri Lanka.
Therefore, to reduce the amount compost by divide a pile of compost, you can either load little by little while replenishing moisture, or replenish water to control water content by using the aeration pipe.
In the below photo compost pile depth is only 20cm, but decomposition is progressing.
It's pleasant to composting of weeds and fallen leaves since it is less odor. I am going to survey composting garbage drifting malodorous tomorrow.
Alan Birch:Economic History of the British Iron and Steel Industry によると Round Oak Steelworks was founded by Lord Ward, later the Earl of Dudley in 1857. と書かれている。この鉄骨は鉄鋼所が1857年にDudley伯爵の所有になった後に生産されたのだろう。
The steel frame of line house in Bawlana has not much corroded even to have become weather-beaten, there was a mark of EARL OF DUDLEY STEEL.
Alan Birch, “Economic History of the British Iron and Steel Industry” said “Round Oak Steelworks was founded by Lord Ward, later the Earl of Dudley in 1857”. This steel frame might have been produced after the steel plant has become owned by the Earl Dudley in 1857.
James Taylor started Loolecondera Tea Estate, the first Tea garden of Sri Lanka in 1865.
Since his grandfather came here in the story of the old man who lives in the line house, it was probably built in the late 1800s.
I found the nests of ants near the office. The size of nest is just a rugby ball.
The fishermen met know in conservation activities of Takasago Seaside Park took us to fish octopus. Departure 5:00 in the morning, factory area spreads out the coastline.
We arrived at the fishing grounds in about 30 minutes, and putted the dragnet.
After trolled for 20 minutes to put the dragnet and raise the net.
A good catch this day, dozens of octopus had entered the net once. A variety of fish is contained also, and it is more interesting than aquarium.
Although the students excited to fish octopus for first time.
During 8, 5 students groggy by seasickness at work on the ship swaying and facing downwards for two hours.
Changes in methods of fishing, culture of fishermen, and the relationship of the sea and dam, the stories of fishermen was interesting.
After past Typhoon 11th, we expected a large amount of sea lettuce was washed up on beach at Takasago Seaside Park. However, there is no sea lettuce, launched just driftwood.
Sea lettuce is not found at all in the deep water where has always accumulated. It seems that all sea lettuce inside the bay flowed out by the west wind. The power of a typhoon is great.
Once again, the contents of the isolated basket of lettuce predation volume survey for moon shell is washed away by typhoon 11th, Mr. N was depression. Sea lettuce is not available even to start the re-investigation.
We would like to know increasing rate of sea lettuce in the future.
Camp of local high school club is the home of Takasago youth, the students collected sea lettuce in the morning activities. We was composting about 1300kg sea lettuce, July 31th.
Task of composting sea lettuce more than one ton the ambient temperature exceeds 32 ℃ was tough. I want to thank that students of sports council were in our laboratory.
After the composting is done, we are finished with the repair of sea lettuce isolated basket predation experiment amount of moon shell and washing the baskets.
I can work together with students that day, but I do not get tired the next day. Old age tires body.
We had composted sea lettuce that collected by elementary school students of Takasago Junior Sports Teams Clean Campaign at Takasago Seaside Park. Because it was when the tide is not pulling, sea lettuce was rather less 40 baskets, 374kg.
First we move the compost with previous sea lettuce. Moisture content is high, so we were trying to mix hay, but hay is not found to have been clean up that the mayor would come only this time.
In order to reduce the water content by increasing the heat generation amount, and apply the rice bran little extra (200g / m²). The sea lettuce load separately in seven layers, width 1m, 2m length, 0.6m height.
Since the bottom had gotten dug in typhoon isolation cage amount of predation study of Batillariidae after the composting work. 1kg lettuce was putted in isolation basket of both, and 400g Batillariidae was putted in only left side.
Mr. N who was baseball original captain in charge of composting sea lettuce would want to go to support of third round prefecture preliminary competition.
He wanted to absent the day before, but he was coming. We rushed to Akashi Park Stadium after finish the work.
The local leader in this project, Yoshimasa said to him "What you are doing, it help yourself in long your life." Will it be time when Mr. N to understand the meaning of this word.
Today 15th July, we finished collecting weed of campus that began on13th June. In hot and humid, it was cheers for good work. Twice a week, three female students of the laboratory of Dr. S also came to help collecting weed in this time.
We made three composting piles (1.5m height 5m length 2m width) with weed.
The compost piles are tighten by jumping at the top of compost piles, because weed these have too many voids.
Upcoming, two piles will be made from three piles, and one pile will be made from two piles with the ventilation pipe, it can be used as compost is finally reduced decomposition progresses in six months.
In order to get to eat Spirogyra generated a large amount when water temperature goes up, it has been observed to 20 Rhodeus ocellatus kurumeus (S size 3cm) and 20 Acheilognathus cyanostigma (M size 6cm) after put in January 2012.
Seems to have had little effect, but it is necessary to skim by human power.
There was an article that says, if you plugged branches of black pine into the intake water of paddy, Spirogyra is exhausted in Monthly Modern Agriculture, August. I decided to try it in the biotope.
I put a branch in rainwater square mini biotope, killifish live in.
I've inserted eight branches in the biotope of the courtyard.
Will there effect?
We set the isolation cage to examine predation amount of sea lettuce by batillariidae.
At first, the isolation cage is carried by the balloon tire drawn cart.
All batillariidaes are picked up in space of examining position and counted. This was hard work. Next time, we should bring hoe and colander to collect and wash batillariidaes in water.
There are 1380 pieces of batillariidaes, 757g in the 900mm × 1800mm.
The assembled the isolation cage and fixed to pile.
The original density batillariidaes are put in one side cage.
2kg of sea lettuce is put in the both cage which one is not batillariidaes for control.
All we have to do now only pray for the success of the experiment.
It is four years since I started working on the problem (outbreaks of sea lettuce) Green Tide of Takasago Seaside Park. Green Tide just looking at the photos below of the next four years ago.
It is now clean shown the photo of the same place today. Parents and children are able to playing in the water.
There is also an effect that is composting sea lettuce by volunteers, but predation of sea lettuce by Batillariidae is not forgot. Density of Batillariidae on shoal is great. This year, I want to examine the density and the amount of predation.
However, since the sea lettuce in sea water can not be prey Batillariidae, sea lettuce is accumulated in the deep part.
The address and family structure of the raccoon dog were found. Their names are kept secret for privacy protection. The address is 679-3, Uozumi-cho Nishioka, Akashi-shi. Earthen pipe in Akahi Kosen. Family structure is parents and three children.
Height of children (about 3 months age) is about 30cm. Although they are cute, grew wild and threatened to approach them.
JABEE program of Akashi Kosen has appealed for "symbiosis with nature and society", I am considering to use the raccoon dog problem as useful teaching materials for students.
We started to compost food waste. After that, raccoon, crow, sparrow and crested myna were coming to scavenge. Because it is dug up if you leave without countermeasures, it was covered with a net at first, but the net is tattered and been broken by raccoon dog.
We were measured in natural systems back to the origin, coved the garbage compost with branches cut down. For now, the crow is prevented, and where the raccoon dog is digging even limited where there is no branch.
Offense and defense with the wild animals continues.
I had been going home with a second son to Wakayama Pref.. The plum tree was pruned in last winter, which made a lot of plums.
Four cups to basket were harvested from the plum tree, but the remaining half still. Since it have been grown in pesticide-free, there is freckle on plums. I think it is ridiculous that only in order to look beautiful, but there is no freckles on plum in supermarket.
I brought back 1.5kg plum and made plum wine. After 3 months I look forward to.
It was scheduled to see firefly in the nearby creek at night, firefly was not flying in rain unfortunately.
The students have composted garbage generated from student dormitory. There was odor when you open the garbage bag, but there stand a few minutes. Too much leftovers, isn`t it.
Criminal who dig up the garbage which was composting process was a raccoon dog after all. Dining in the top of the garbage compost without fear the fence which I made with stepladder.
The raccoon dog was not afraid man and did not escape. Now, what can we do?
We started composting of garbage generated from student dormitory. Compost is covered with the net, because garbage is dug, but it was a mess to eat garbage again, the net is turned over when I looked in the morning. The suspect is raccoon dog or crow. Raccoon dog is most doubtful from the scene of the crime.
I have written "Reading Kobe Newspaper" on Sunday every week for June. I thought easy to write the column of 1040 characters per a week. However, reading a newspaper article of 500 words and writing a column of 1040 characters, that is like writing a longer report than the book read. I changed the strategy. First I decided a theme what I want to write, then searching the related newspaper article later. 5 papers are finished with this strategy.
Recently, it is the daily routine to walk barefoot with my son after dinner. You can not walk on the hot asphalt road in the daytime in this season, but it cool down to be just about the right temperature at night.
At first, you have a sore foot on irregularities of road, but you will be comfortable after become accustomed. I'm do not care to be seen by people, but my son of fifth grade seems to be a little embarrassed.
３．初心者には使ってもらう斧は柄が強化プラスチックでできているFiskars/X25 Splitting Axeを使うべし。お気に入りのソマウド１５００を折られてしまった（涙）。
The wood-splitting workshop using thinned wood in Akashi Park was held by Hyogo Park and horticulture association, NORITZ CORP., and Akashi College of Technical. I am relieved to be able to complete without injury with good weather. It was the first attempt, it is trial and error is necessary in the future.
The lessons of wood-splitting workshop are written below.
1.Wood-splitting workshop with massively multiplayer beginners is unreasonable.
Since wood splitting is scary at first, adrenalin comes out of it. Thereafter, it will become the high tension in the interaction, dopamine come out when you can split wood.
It becomes dangerous tension a little with population. It is distinguished for event, but it is hard to control.
2.Individual guidance is needed for wood splitting
While swing scary the axe is no problem. As you become more accustomed, you started swing strongly axe without being able to control axe head. This time is dangerous.
40 persons and one lecturer were slightly impossible plan. It may be available if students growth until serving as lecturers role.
3.Fiskars/X25 Splitting Axe the handle is made of reinforced plastic for beginners use. Somaudo 1500 was broken which is my favorite (tears).
It seems that participants enjoyed, the management side felt uneasy. Appearance of this wood-splitting workshop is broadcast on cable TV Akashi ACTV135.
The photographs have been sent from Mr. I of NGO APCAS who has collaborated in Sri Lanka. The leaf of coconut for the rain-cover which I was asking is on the compost pile.
The new compost pile was made by soldier of Sri Lanka next the old compost pile.
The pipes supplied in the local which are made aeration holes were inserted in the compost pile.
You can do it!
I am glad that small species were seeded in Sri Lanka seems to have sprouted.
Before returning to Japan, we had seen the compost which was piled in two days ago at Viharamahadevi Park. Since the rain-cover was not shielded, the temperature at near surface had fallen down with rain, but temperature was going up to 60℃ at the center of pile. Subsequently decomposition is in progress and the compost pile is going to be smaller, so fallen leaves and cutting grass should be carried on the pile.
There are many young soldiers, it is not problem of labor.
In the rest, only a motivation is.
We had meeting which is the project explanation and exchange of opinions to the leaders of Kaduwela (commissioner, municipal, executive officials) today.
New experience which does work over different culture is likely to be made for myself.
The composting experiment of fallen leaves and grass which comes out in Viharamahadevi Park which was named Queen Victoria parks at British colonial days at the center of Colombo city has been started today. The park is owned by Colombo city council, other wide it is managed by military.
We tied two 2.5m pipes carried from Japan by band, and made 5m pipe.
Coconut husks fiber is spread as heat insulating layer which thickness 10cm on the ground. The pipes for aeration are put in and grass and fallen leaves which were loaded about 20 cm.
Dry compost is spread each time you covered 20cm thickness grass or fallen leaves for moisture content adjustment and seeding.
A ventilation pipe is put on three layers, however fallen leaves and grass were used up, we had to wait to gather material in the afternoon and work was resumed.
Although it was rain and army and city officer motivation were down, we demanded continuation of work.
The compost before to become a product with screening had been piled in composting facility Kaduwela. Since many undecomposed organic matters were contained, the inside was over 60℃ with heat of decomposition. The layer of thermophilic aerobic actinomycete bred splendidly at 5cm – 10cm form the surface of compost had seen white.
Thusare is a massage shop for visually impaired persons has run by NGO APCAS collaborated with me in Sri Lanka. Religious prejudice "with disabilities to perform because of previous life was bad" and misunderstanding "massage industry = sex industry" are present in Sri Lankan society.
Significance launched a social business for creating jobs of visually impaired persons in such an environment is great. Thusare is opened in Good Market on Saturday.
After I helped to set the store, I had foot massage a (300Rs) at 1th customer. Please get a massage in Thusare, when you come to Sri Lanka.
Yesterday, I went to set composting pile of the second experiment in Kaduwela.
Return compost was paved on the concrete floor for thermal insulation and moisture absorption, and the ventilation pipes were placed.
Mixed garbage and return compost in volume ratio 1:1 which is placed on the pile.
When the pile are reached at setting height, ventilation pipes are set again. It is repeated.
Front half compost pile that does not put the pipe for comparison.
The problem is high moisture content of return compost which stored at outdoor. It is necessary to use return compost is large particle size and dry for improving the ventilation rate and moisture control. After that, it is necessary to pick up plastic waste.
Last time, I suggested to mix return compost and it has been executed. It was delighted to smell has become less. It's a step forward.
It was good though there are fruits, when I eat spicy Sri Lanka curry every day.
In particular, banana saved me. It is possible to see many kinds of tropical fruit papaya, gabba, palm and other types of fruit in the garden.
Coconut were taken at next house. It is a high altitude dangerous work. Yeah come on business can have craftsmen who take the coconut in a single 200 rupees, to become the time taken. There are craftsmen who take the coconut for 200 Rs per 1 time. They come to business at the harvest time.
Everywhere you can see mango which is expensive fruit in Japan.
Fruit of searching name in English. It is sweet.
