Sowing Unit Soil Pressure Reduction via Elastic Tires
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for increasing crop productivity in seed crops, such as pre-sowing land tilling for weeding, are inefficient as they fail to remove germinating weeds effectively, lead to soil moisture loss, and rely heavily on inorganic fertilizers, resulting in high costs and low ecological compatibility.
Innovation Solution
Seeds are planted in wet, overmoistened soil using a sowing unit like 'Bars UTES 271' with elastic tire covers or an air-cushion device, minimizing soil pressure and energy consumption, allowing for deeper seed placement and reduced fertilizer use, optimizing sowing speed and depth for improved soil interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-sowing land tilling is carried out for weeding, then well-rooted weeds are removed, but germinating weeds remain and soil moisture is lost
Solution Approach 1:
The patent applies preliminary action by performing sowing operations immediately after snow cover melting or rain, taking advantage of the naturally moist soil condition before any cultivation. This eliminates the need for pre-sowing tilling while ensuring seeds are placed in moist soil, preventing both weed germination and moisture loss.
Solution Approach 2:
The patent extracts the essential function of moisture conservation by directly sowing into moist soil without performing land tilling. This removes the harmful step of cultivation that causes moisture loss while maintaining the beneficial outcome of timely sowing.
2Reliability
If land cultivation is deferred to remove germinating weeds, then weed control improves, but optimal sowing time periods are missed and productivity decreases
Solution Approach 1:
The patent performs sowing as a preliminary action immediately when soil moisture is favorable (after snow melting or rain), before weed germination becomes a problem. This timing strategy ensures both optimal sowing conditions and effective weed control without deferring operations.
Solution Approach 2:
The patent utilizes the natural moisture from snow melt or rain to create favorable sowing conditions without requiring additional cultivation operations. The moist soil itself serves the dual purpose of enabling timely sowing and suppressing weed germination.
3Productivity
If inorganic fertilizers are applied to increase crop productivity, then yield increases, but soil microflora is adversely affected and humus decreases
Solution Approach 1:
The patent changes the parameter of soil moisture content by sowing into moist soil, which creates favorable conditions for seed germination and early plant development. This natural moisture regime supports healthy plant growth and soil microflora without requiring inorganic fertilizers.
Solution Approach 2:
The patent allows the natural soil moisture from snow melt or rain to support crop productivity without external fertilizer inputs. The system uses naturally available resources (moisture) to achieve high yields while maintaining soil health.
4Use of energy by moving object
If seeds are planted in wet or overmoistened soil, then sowing energy cost reduces and friction decreases, but soil pressure requirements change
Solution Approach 1:
The patent changes the physical state of the soil from dry to wet/overmoistened, which fundamentally alters the friction characteristics between soil and sowing unit openers. This parameter change reduces the energy required for sowing operations.
Solution Approach 2:
The patent employs pneumatic principles through air-cushion devices that utilize compressed air to reduce the contact pressure between sowing unit openers and the soil. This hydraulic/pneumatic approach minimizes soil disturbance and energy consumption during sowing.

AI summary
A method of increasing crop productivity, including in the areas of risk farming, based on sowing time optimization, noted for the seeds being placed in the wet overmoistened and / or slurry-type soil, perhaps under the rain, right after the rain or immediately after the snow cover melting, the sowing unit traveling speed being 1-60 km\h, provided that a technological transport vehicle capable of operating under pressure on soil of 0,4kgf\cm2 or less up to zero, for example, "Bars UTES 271" on the elastic tyre covers or the air-cushion device is used as a sowing unit power device. In this case the seeds are placed just under the overmoistened soil layer with the depth of penetration being from 0,2 to 15 cm.
