DESCRIPTION:
BRIEF SUMMARY
The invention relates to land management and in particular to an apparatus for use in managing soil irrigation.
Agricultural production techniques typically involve the ploughing, cultivating, harrowing, sewing, rolling, inversion, stirring and compacting of land. These activities are undertaken with the intention of obtaining maximum crop yield at minimum cost per acre of cultivatable land. However, such practices have created problems. These problems include soil surface erosion and difficulties in ensuring uniform soil irrigation.
I have therefore produced a unique and relatively light weight means, compared to conventional agricultural equipment, for manipulating a loose bare soil surface. This means enables the profile and texture of the soil surface to be transformed so as to minimize against soil erosion and to provide for uniform soil surface irrigation. Further, the means is propelled using land management rollers that can travel either on agricultural land or road and when used on land these rollers have self-cleaning properties. In addition, the nature and number of said rollers can be modified according to a user's requirements.
According to a first aspect of the invention there is therefore provided a land and roadworthy apparatus for use in land management comprising a driving means for moving the apparatus over land or along a road; and at least one wheel or drum member on which said apparatus, at least in part, travels, which member is adapted to be friction free or self-cleaning when travelling on said land and further includes a plurality of spaced peripheral ridge members; whereby movement of the apparatus over land creates a series of land impressions corresponding to the nature and number of ridge members of the apparatus for the purpose of preventing soil erosion and ensuring uniform irrigation.
It therefore follows, that the ridge pattern on the said wheel or drum member will create a series of land impressions in the form of, preferably, equi-spaced land recesses, the result being that land thus treated will be fashioned in a manner which safeguards against erosion and further will be provided with a number of functional irrigation ditches so as to ensure that water (both rainfall and irrigation) retention across the land surface is substantially uniform. This latter advantage is essential where the precipitation rate is greater than the infiltration rate and/or the soil is lable to "capping".
These conditions can apply to any bare land which in the UK arable farmers' calendar amounts to:
In a preferred embodiment of the invention said wheel or drum member is mounted on at least one axle occupying at least one axis and means are provided so that the nature and number of wheel or drum members can be varied according to a user's requirements.
In a preferred embodiment of the invention the wheel member is adapted to be friction free by being of a resilient nature and ideally is made from a rubber material which may be fluid filled. Further, the wheel member may be a heavy duty and load bearing member, suitable for furrow presses, or alternatively, the wheel member may be smaller in diameter and of lighter construction and so less in weight, suitable for machines that are fitted by tractor three-part linkages, for example planters, drills, harrows, cultivators etc.
In addition, the resilient nature of the wheel member creates a situation where land treated by the apparatus in the invention is not compacted, in a traditional agricultural sense, but rather it is impressed. This has obvious advantages for crop cultivation.
Further, it is desirable that the number and nature of ridges are such that the recesses created represented 50-100% of the soil surface worked by the apparatus and ideally the size of the recesses are small relative to the size of conventional wheels or agricultural equipment so that such wheels are substantially supported, on a level plane, by the ground surrounding said recesses.
It will be understood that the shape of the recesses may be varied in accordance with req
