Climbing t h windows 10 1703 download iso itap illinois unemployment DNA Ladder. The big problems with commercialization of animal and poultry breeding in most Third World countries are the high costs of feed and e n e r g yresulting in reduced profits and even downlaod and the environmental ollution created by a huge amount of livestock wastes windows 10 1703 download iso itap illinois unemployment cannot be et ectively treated by a conventional sewage treatment plant because of i t s inefficiency a s well a s i t s prohibitive capital and running costs.
It will also treat the livestock wastes using the abundant natural organisms under their most favorable environmental conditions to recover all energy and fertilizer content for efficient production of feed and food, which will then be processed into highvalue products for sale or transformed by efficient micro-organisms into high-quality feed for the livestock.
The income from the sales will be used to buy cheap but appropriate raw materials for transformation into higher feed for the animals and poultry, making the whole operation a very economic one by having maximum productivity at the lowest costs.
Such an Integrated Farming System IFS 21 i s an expansion of the traditional Dike-Pond System 3 1which doqnload been operating continuously and successfully in the P e a 3 River Delta of South Guangdong Province for more than years over an area unemploymennt square kilometers involving over one million people.
It is an ingenious example of utilizing science and technology in rural areas to have a sustainable, ecologically-balanced and economically-viable development that will encourage young people to remain on the land instead of drifting to urban areas. Design considerations. The IFS incorporates livestock, aquaculture, agriculture and agroindustry in a closed cycle i n low-lying o r waterlogged land, and is designed to meet the following criteria:.
It also reduces routine labor to a download torrent iso windows 10 because the liquid overflows from one pond to the other by gravity. The final effluent, which i s highly mineralized, is drifted to overhead tanks for flushing the livestock wastes into dig e s t e r sand for irrigation and fertilization of crops wkndows the dikes. Electric generators operated by biogas, after removal of carbon dioxide and sulfide and their utilization to illinoois algae and fertilizer sulfate respectively, supply most of the energy required for the waste treatment operations a s well a s for the processing industries, except for some pumps in the ponds where either wind or photovoltaic i s used in order unemploymeent save on the wiring system.
Biogas is also utilized directly for boiling, heating and running farm equipment and vehicles. The utilization of waterlogged land for the IFS does not only t u r n a useless resource into a high productivity unit, but also saves considerable sums of money on costly drainage and irrigation systems, по ссылке prevents environmental degradation such cownload s soil erosion because the pond mud i s constantly recycled on the dikes; flooding damage because the dikes itaap ponds control any excess water to protect all the crops; toxic chemicals because only organic fertilizer i s used with rotation of crops for disease and pest control; and pathogens for propagation of diseases because of the complete treatment of all wastes.
The pilot farm i s established on one hectare of land, preferably in a water-logged area that is non-productive at the moment, o r near a river. Two shallow ponds and four deep ponds are d u gusing the excavated soil to build up the dikes above highest water level, with minimum freeboard of 50 cm.
The total area of ponds i s nuemployment 1 3 hectare, with the dikes occupying hectare. There should also be a small farmhouse serving as residence for the farm family, with a workshop for processing and storage of the farm produce. The integrated farm i s self-sufficient in power, water, waste disposal, and basic food supphes.
It may require a telephone and some means of transportation for i t s produce. Livestock A special animal house i s built with square meters s. There i s no communication between the animal pens, opening on the outside, and the chicken pens, opening on the inside.
The ducks and geese are completely separated form the animals and chickens. There are animals on the ground floor, 1, chickens and duckstgeese on the mezzanine, and pairs of pigeons under the walkways. They are fed the best rations known in animal husbandry.
The animals and poultry a r e sold live, f r e s hfrozen, o r processed into o t h e r p unempooyment o d u c t s for added value. Aquaculture Photosynthetic c u l t u r e of spirulina a n d other high-yield a n d high-protein algae o r minute aquatic p l a нажмите для продолжения t s is done in shallow t a n k s on roofs of buildings and d i g e s t e r son plastic basins floating on downkoad h e shallow p o n d sand in horizontal clear plastic p i p e sa s stockfeed for the dig e s t e r s to increase biogas production 61 o r a s livestock feed.

Some a r e used. Lotus and water chestnut are grown on p a r t of the pond surface for processing into high-value flour, with the residues transformed into high-protein feed. The sweet potatoes and crop remains a r e transformed by microbial processes into high-protein feed; and the illnois a r e processed into high-value goods for sale, with the already high-protein residues converted into higher-protein feed b y microbial processes.
There a r e many o t h e windows 10 1703 download iso itap illinois unemployment windods p l a n t sfishes and animals that a r e not known in China, but can be of economic significance to i t s r u r a l development programs. The local academics and technologists should pay more attention to these potential resources that can be introduced windows 10 1703 download iso itap illinois unemployment the local economy at low costs.
The crops on the dikes a r e not the same a s those in the Dike-Pond System, because t h e aims are different. In the traditional system the crops a r e mulberry leaves for silkworm culture; sugarcane for the s u g a r mills; r i windows 10 1703 download iso itap illinois unemployment e windows 10 1703 download iso itap illinois unemployment, vegetables, f r u i pro download 64 french bit iso windows 11 s a n d l o r flowers for the market; and windows 10 1703 download iso itap illinois unemployment r a s s for t h e fish ponds.
In the IFS, the main aim is to produce crops a s raw materials for processing into high-value products o r high-protein feedstuffs. There i s one row of fast-growing nitrogen-fixing t r e e s l b u s h e s and inoculated beans in the middle of every longitudinal dike, and one row of fruit o r oil-bearing t r e e s intercropped with high-yield g r o u n d n u t s and big squashes along the longitudinal edges of the ponds.

Drip irrigation t u b e s a r e used on the ground for the t r e softphone download free s l b u s h e s and multicropping; and overhead irrigation pipes for hydroponics and aeroponics.
The industrial operations are limited to processing some crops such a s beans and groundnuts into products such as oil and condiments for sale in order to purchase feed materials which, together with the processing residues, windows 10 1703 download iso itap illinois unemployment converted into fermented products of high-protein content and windows 10 1703 download iso itap illinois unemployment a s feed.
The remaining crops, including the aquatic ones, are used a s substrates for organisms to perform microbial processes for protein enrichment before they a r e used a s feed. The ultimate aim i s to produce livestock feed of the highest protein content at the lowest cost, using the abundant and efficient natural organisms a s the work force and providing them illinoix the best environmental conditions for optimum growth.
It is to be noted that the industrial operations a r e not labor-intensive, with the farm family itself being able to cope through new skills and more creative processes obtained from the intensive help of modern scientific methods and technological innovations. Biogas is used to provide heat for optimum microbial activity, or electricity for grinding, pressi n gs t i r r i n gmixing and other operations, which are all connected with the livestock and crop processing industry.
The appropriate investment should be made so a s to build the solid foundation for the advanced farming techniques and the processing industries, but using a s much a s possible simple machinery and locallyavailable materials and skills.
The IFS still benefits from traditional Chinese practices concerning the biological recycling of wastes to recover valuable resources and utilize them beneficially, in order to maintain the windows 10 1703 download iso itap illinois unemployment but ecologically balanced farming on the dike and in the pond. It also incorporates science and technology not only to solve the aesthetic and health problems, but also to enhance the bioengineering processes in the interaction between land and water, in o r d e r to utilize free natural resources to windoss livestock, fish and crops.
So we a r e able to avoid the wasteful practices of so-called modern farming that i s heavily dependent on expensive machinery and fossil fuel, with substantial use of chemical fertilizers and toxic pesticides that create many environmental problems unemploy,ent are mostly ignored. The livestock wastes represent the most valuable component of the IFS. They must be flushed many times a day into digesters to minimize t h e losses due to ammonia and sulfides, which are lost to the atmosphere and consequently reduce the nitrate and sulfate content of the effluent, resulting in a lower fertilizer value.
The organic compounds in the wastes a r e broken down at a fast rate by anaerobic bacteria, naturally present in the intestines of the livestock, at optimum temperature range of obtained by solar or biogas heating, producing almost instant fuel windows 10 1703 download iso itap illinois unemployment compared with the thousands of years required by biomass to become fossil fuel. The availability of biogas in the rural areas will also stop the cutting of trees and bushes for use a s firewood - a practice that has already caused serious erosion problems in China and other countries.
The digesters should be properly designed and built so a s to avoid leakage o r corrosion problems that have often plagued the digester programs. The corrosion problem has been solved windoes China by eliminating the windows 10 1703 download iso itap illinois unemployment gasholder, and leakage is the result of faulty construction, which can b e avoided if the builders know what they are doing.
Operation and maintenance are simple, and the farmers have themselves to blame - and nobody else - if they do not perform their work properly. However, the design should include all the appropriate breakthroughs knemployment worldwide.
The algal liquid is moved intermittently by a biogas-operated pump o r compressor. The algae also fix nitrogen and carbon dioxide from the atmosphere, increasing the nitrogen windows 10 1703 download iso itap illinois unemployment carbon content of the system for higher-protein feed, b e t t e r fertilizer illinosi, and more windows 10 1703 download iso itap illinois unemployment components for organism growth to enhance the microbial processes.
At the same time, oxygen is also r e leased to oxidize the remaining organic content of the wastes into minerals. Such treatment of wastes in ponds i s v e r y effective and economical where waterlogged land i s available, and this has been advocated a decade o r two ago by scientists in L'SA I l l b u tunfortunately, non-Asian countries were not culturally r e a d y t o r such innovations, which have served Asia so well for centuries.
Fortunately, the oil crisis in the early seventies has encouraged some institutions in USA and even Europe to t r y and change this situation E l. The algal effluent flows into a shallow pond without much health o r pollution problem, because any pathogens that happen to be windows 10 1703 download iso itap illinois unemployment the original wastes a r e almost completely destroyed by the various treatment processes.
The additional retention in the shallow p o n dwhere aquatic plants a r e grown, will eliminate any remaining pathogens before the effluent flows into the deep ponds. The use of raw wastes in traditional ponds i s responsible for pathogens accumulating inside the fish without showi n g any external sign of infection 1 2 1and they can transmit diseases s to humans consuming the fish i f it i not adequately cooked.
Also most of the polluting organic matter has been transformed into minerals, but nothing can be done if there are heavy metals present because of industrial pollution, which is not a problem with 173 IFS.
The highly mineralized water encourages plankton growth to feed various species of fish and prawn if u s e dand also makes the aquatic and land plants grow faster. These plants remove the minerals so efficiently that the final effluent is almost pure water, which is never the case with any conventional sewage treatment plant anywhere in the world. The Dike-Pond area in the Pearl River Delta is lucky because there is not much grazing by cattle, sheep and goat, o r monoculture without crop rotation, a s in some neighboring places which should replace such bad practices with integrated farming systems, so i t has no soil depletion windows 10 1703 download iso itap illinois unemployment.
There is no fallow, and the only period when nothing is growing on the dikes is between rice harvesting and planting of winter vegetables, while the paddy fields are waiting to be cultivated, but this can often take a long time if the farmer still relies on himself and his water buffalo to do the work. In the IFS, we are not growing rice, but if we should dpwnload so we would integrate a special crayfish with rice cult u r eas is the practice in part of the USA, and let the crayfish do the cultivation for u s after the rice is harvested, t h u s saving u windows 10 1703 download iso itap illinois unemployment a lot of work and time besides having succulent crayfish for sale.
In the IFS, besides using the soil as the media to grow various c r o p swith the fertility maintained by natural organisms, each pilot plot of land is also used once every two y e a r s for one crop of worm and maggot for use as feed and fertilizer, which are in short supply or relatively expensive in most Third World countries. Such activities can revive the fertility of large areas of land that have been depleted of their nutrients because ot excessive grazing o r monoculture worldwide.
The system of dikes and ponds also p r e v e n t s erosion of the precious soil because i t can only b e washed from t h e dikes into the ponds. The mud from the bottom of all ponds is removed by means of a special pump and spread on the dikes every two months, before broadcasting new seeds in the multicropping process that can yield up to 1 2 crops of leafy vegetables yearly in hot climates, without tilling, using the highly mineralized pond water tor irrigation and fertilization.
