Vladimir Vasilyevich Fokin in 1990 has invented manual cultivator which has been called by his name. This device allows to work in garden, without making special physical efforts. It is possible to make such tool and in house conditions.
What is Fokin's subsurface cultivator
Before starting production of the subsurface cultivator of Fokin, it is necessary to understand that it represents and what principles of its work. Main issue in operation of this device – plane cutting of the soil at depth from 5 to 15 cm. Thus roots of weeds are cut, and cultural plants remain whole. At the same time the cut roots die off and fertilize the soil. Other important effect – soil loosening which increases its hydroskopichnost. Therefore if to use the subsurface cultivator regularly for several years, the structure of the soil considerably will improve, and the productivity will grow many times.
One more good point – ease in use. Physical activity during the work with manual cultivator of Fokin is minimum, it is lower than work with garden chopper or shovel by 2-3 times. It is excellent exit for people who have problems with health, for example, diseases of joints, backbone, cardiovascular system, etc.
Thickness of layer of mulch does not affect results of operation of the subsurface cultivator of Fokin. The hand tool differs the in universality. With its help it is possible to carry out up to twenty various operations.
Among the most demanded – horizontal loosening of the soil up to 5-10 cm by means of plane cutting (it is applied on not sowed beds and row-spacings). Often the device is used also for forming of beds which is made by serial prigrebaniye of the earth and the cut-off weeds from both boundaries (it is better to adhere to the optimum width of bed in 1 m).
Alignment of surface of bed is made by deepening of edge on 1-2 cm to which it is necessary to row smoothly or sharply along bed and on itself. In process the lumps of the earth are crushed. If smoothly to move on northern boundary, the southern slope of bed is gradually formed.
The subsurface cultivator and for cutting of grooves for seeds and the subsequent powder, weeding of weeds is useful. Here technology of ploskotsny loosening before crops and 3-4 times after crops with breaks in week is useful. If to use the tool as garden chopper, it is possible to hill quickly and effectively crops
The garden subsurface cultivator will help to loosen strawberry and to chop off mustache, to cut off young growths of raspberry and weeds, to take with root the weeds growing very close with garden and garden cultures (at the same time it will not even be necessary to bend), to crush large parts of manure and to evenly distribute fertilizer on beds, to loosen pristvolny circles of fruit-trees and to execute many other operations.
How to make Fokin's subsurface cultivator with own hands
Such useful device which considerably will facilitate work on kitchen garden can be bought, but it is more expensive than normal tools. For the purpose of economy it is possible to make it with own hands in house conditions, using improvised tools.
For production of the subsurface cultivator of Fokin it is necessary to choose suitable metal strip. Its length has to be about 40 cm. Make the drawing, having noted on it bend points – them there will be 4. Transfer points to strip and note them there.
Take the prepared metal strip in vice, then the hammer bend it on earlier put marks in 4 steps. The first bend of the subsurface cultivator forms letter G. The second inclines vertical strip. The third bends it aside. The fourth bend forms final form.
Now we have semi-finished product of which it is possible to make the tool-kornerez. For this purpose drill 2 openings on the site which will fasten to wooden shank. The end of work area of the subsurface cultivator needs to be cut off at an angle in 45 degrees. The sharp end with which it will be easy to loosen row-spacings has to turn out and to delete weeds.
The most important point – sharpening of tools. From that, sharpening will be how correctly carried out, simplicity and efficiency of work with the tool depends. The subsurface cultivator – two-edged subject therefore and it is necessary to sharpen it from two parties. Do not forget about cut on the end of work area. Next time it will be manually necessary to imprison Fokin's subsurface cultivator only in several years.
It is important to consider the tool sizes. Vertically put tool is 20 cm below than shoulder. Proceeding from it calculate length of shank of the subsurface cultivator and tighten its shurupm and bolts. The device is ready.
