ARTIFICIAL, FLOATING, MOVABLE, TILLABLE SOILS

Abstract: The object of the invention is to increase the agricultural production of certain countries by creating artificial tillable soils suitable for countries where lack of fresh water, desertification, environment deterioration have reduced the number of arable lands or where stealing land from the sea is too expensive. They are inflatable, floating, easily transportable modular platform (1) units intended both for fresh water and seawater farmers can join one another to form only one field under cultivation which they will be able to till with traditional farming methods or hydroponics, to work by hand or by certain agricultural machinery, to tow by any boat. Thanks to the high inside temperature the covered version intended for seawater allows this one to turn into fresh water: during the day the former will evaporate through a hole (11) in the bottom of the platform; the latter will drip on the crops as soon as seawater condensed.

Description: Description Artificial, floating, movable, tillable soils Technical Field My invention relates to farming and particularly to methods that are employed to increase the agricultural production of certain countries by extending their tillable soils . Over the last 50 years breaking up of waste lands and spreading of watering systems allowed people to till soils that were formerly unwatered and to crop more than once every year; moreover increased tillable areas have only partly counterbalanced soils got lost because they have been turned into lands not intended for farming, they have been eroded or deteriorated. In addition, the progressive reduction of tillable soils can't be offset because population is increasing in a few countries and productivity of cultivated lands has stopped since 1990. Background Art Shortage of tillable soils is troubling both people whose arable lands have been progressively reduced by dustbowl and people living in countries that are too small compared with the number of their inhabitants; up to now, all measures adopted to get around the problem suffer the big disadvantage of involving complex hydraulic works and consequently heavy obligations. The worst of it is that people can operate only on their national territory, so farmers will never have the chance to increase their fields unless they are in a position to steal land from the sea (Netherlanders are well-known as the main supporters of this technique). However, certain geomorphologic peculiarities are required for this kind of intervention. It often happens that dams and artificial canals cause a serious change of climate and irreparable damage to the environment as well. Moreover no hydraulic work can prevent a partial waste of water resources: in fact, water dammed into artificial basins and channelled towards barren lands partly evaporates because of the sun and what' s more irrigated fields soak up only a certain percentage of water while the remainder ends by getting lost in the earth more than is absolutely necessary to keep moist the soil. Finally, people settled in waste areas resort to archaic expedients to pump water from the subsoil by capillarity but these ecological methods allow neither a drop in evaporation, nor a total recycling of water resources, nor even an intervention on a large scale. Disclosure of Invention In accordance with the present invention, I provide an artificial, floating, movable soil suitable for countries where lack of fresh water, desertification, environment deterioration have reduced the number of arable lands or where stealing land from the sea is too expensive. They are inflatable, floating, easily transportable modular platform units of 50-100 square metres intended both for fresh water and seawater farmers can join one another to form only one field under cultivation which they will be able to till with traditional farming methods or hydroponics, to work by hand or by certain agricultural machinery, to tow by any boat. Such artificial soil consisting of particular containers one can use in the presence of natural expanses of water or artificial basins and canals (apart from the fact that he has fresh or salt water at his disposal) will give people the possibility of increasing their tillable soils leaving the countries where they reside out of consideration, creating cultivable lands of different sizes, using soils of every kind (soil rich in minerals, clavey ground, peat, etc., depending on what farmers will cultivate), following traditional farming methods or hydroponic farming methods or both, using certain agricultural machinery (engine-driven cultivators, for instance), intervening on a large scale, taking care of their gardens with ease, paying a small sum for ordinary maintenance, covering the cost of repairs without spending much, transporting their agricultural products easily, recycling water resources, curbing evaporation. The standard container intended for fresh water (lakes, rivers, canals, shipways) is an inflated double-bottomed platform consisting of tubular components made up of several internal sections. The diameter of each tubular component is about 65 centimetres. The inner perimeter of each platform measures ten metres by five at least. One can make this special garden by choosing from among three materials: 95 rubberized canvas, synthetic rubber, polyvynil. The rectangle is provided with an additional flat bottom. Besides making the whole container stiff, it will protect the structure below from agricultural machinery (small-sized engine-driven 100 cultivators, mowing machines, etc.). Farmers can place agrarian earth or infertile substratum on such bottoms. So it will be possible for them to employ both traditional tilling and hydroponics. Watering is assured by a removable sprinkling pipe 105 drawing about 50 centimetres below the optimum load line. It is to be connected to a water pump. In case one should irrigate his fields through electrical water pumps connected to simple siphons, it will be possible for him to use solar energy or 110 Aeolian energy to generate electricity. Only two sides of each platform have been furnished with an assembly system allowing other identical platforms to fit perfectly in the transverse direction as well as in the longitudinal direction so that the 115 size of each artificial field can vary as needed. It' s an overhanging belt consisting of an additional tubular component farmers can furthermore use to walk along the perimeter of each floating field. Every container consists of three 120 main components: platform, side belt, overhanging belt. Each of them is fitted with its own air inflow system based on a main duct connected to only one chief inlet valve; further air ducts, each one linking up with the respective tubular 125 component, lead off the main duct. Containers can be made either from tubular components equipped with one-way inlet valves or tubular components equipped with two-way inlet valves. The former version don' t run the risk of sinking if a few 130 tubular components suffer damage because these don't depend on each other. Moreover people will be in. a position to recycle their water resources: whenever they sprinkle a field lying on the dry land, water in excess, or rather water cultivations 135 didn't soak up, usually desperses in the earth; on the contrary, all the containers have been furnished with special outlet pipes discharging surplus water into the same basin from which it has been pumped. In fact, each additional flat bottom 140 is perforeted: every 76 sq.c. there is a hole to which corresponds a sort of funnel fitted in the tubular components functioning as a miniature sewer. Finally, such floating soil is movable: in fact, its tubular components are kept together by 145 simple ropes to which people can fasten any boat by means of an ordinary tow-hook. So, farmers will be able to carry their products by themselves. The covered version of my container is a real floating greenhouse intended for seawater. In that case, 150 velcro is the best material to use for providing its transparent synthetic cover with practical, economic fasteners. Such a cover not only makes sure that an optimum microclimate for special cultivations forms inside the container but it also 155 allows seawater to turn into fresh water: during the day the former will evaporate uninterruptedly through a hole in the bottom of the platform; the latter will drip on the crops as soon as seawater condensed because of the high temperature. After 160 trickling down the inner side of the cover, a great quantity of fresh water will certainly gather in the tilled belt running along the inner perimeter of the platform; so, this type of container is to be equipped with proper irrigators. For instance, 165 the cheapest model could be supplied with some strips of cloth meeting at the centre of the field under cultivation: water in excess will be equally divided among the crops when all the rags have become impregnated with it. Both the container 170 intended for fresh water and the container intended for seawater can be towed; otherwise the small- sized ones can be provided with outboard motors, so that farmers are able to deliver their products directly. Moreover, once they have deflated all the 175 tubular components, the facility with which they can carry them is astonishing (containers can be deflated only if their air ducts are furnished with two-way valves). In the end my containers consist of tubular components similar to ones used for 180 manufacturing rubber boats, as well as simple water pipes, air ducts, ropes, strips of cloth, velcro fasteners that are on sale everywhere. If farmers use components that are easy to find it seems logical to suppose they can take care of their 185 gardens with ease, pay a small sum for ordinary maintenance, cover the cost of repairs without spending much. Men irrigate dry lands by artificial canals drawing water from springs, lakes, rivers, fossil groundwater tables; it often happens that 190 these water supplies are thousands of kilometres from the future tillable soils. Besides being economical in comparison with this way of watering, my containers allow an intervention on a large scale and protect water below from the sun. Unlike 195 all the traditional hydraulic works, they don' t require a radical change in the geomorphology of the area where people use them and don' t cause any change of climate or damage to the environment; farmers must only move their floating soils by 200 rotation to allow the sunrays to filter through the whole expanse of water they have occupied. Dams and artificial canals can' t get the same result: anyhow they are either in the sun or insufficiently shady, so water they hold is more subject to 205 evaporation. Brief Description of Drawings Drawing 1/2 consists of Fig. 1, 2, 3. Fig. 1 is a zenithal representation of a standard container 210 intended for fresh water. It' s an inflated double- bottomed platform (1) consisting. of tubular components. Watering is assured by a removable sprinkling pipe (2) connected to a water pump. Only two sides of the rectangle are provided with an 215 overhanging belt (3). Fig. 2 is a longitudinal representation of the same container (side C) pointing out its additional flat bottom on which farmers can place agrarian earth (4) or infertile substratum (5). One sprinkling pipe (2) drawing 220 about 50 centimetres below the optimum load line (6) is enough to allow watering. Fig. 3 shows the side B of the container. Only two sides of each platform (A, D) have been furnished with the aforesaid overhanging belt (3) consisting of an 225 additional tubular component. 8 Drawing 2/2 consists of Fig. 4, 5. Fig. 4 shows that tubular components are kept together by simple ropes (7) to which people can fasten any boat by means of an ordinary tow-hook. Platform, side belt, 230 overhanging belt are fitted with their own air inflow systems based on a main duct connected to only one chief inlet valve; further air ducts (8), each one linking up with the respective tubular component, lead off the main duct. Special outlet 235 pipes discharge surplus water into the same basin from which it has been pumped In fact, each additional flat bottom is perforeted: every 76 sq.c. there is a hole to which corresponds a sort of funnel functioning as a miniature sewer. The 240 figure shows in detail how every funnel is to be fitted in the tubular components (9). Fig. 5 shows the covered version of my container intended for seawater. Its transparent synthetic cover (10) not only makes sure that an optimum microclimate for 245 special cultivations forms inside the container but it also allows seawater to turn into fresh water: during the day the former will evaporate uninterruptedly through a hole in the bottom of the platform (11); the latter will drip on the crops as 250 soon as seawater condensed because of the high temperature. Best mode for carrying out the invention From the technical point of view my artificial 255 floating soils are to be manufactured by employing the same process used by firms manufacturing rubber boats . Industrial applicability Chiefly food industry that is connected with agricultural production.
