Site-Specific Fertilizer Application for Potato Cultivation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fertilizer application methods in potato cultivation are not optimized for varying soil conditions, leading to uneven tuber growth, reduced yield, and increased costs due to oversupply or undersupply, and do not account for specific soil structures and quality requirements.
Innovation Solution
A method and device for site-specific and part-area-specific fertilizer application using a GPS-controlled system that adjusts fertilizer composition, quantity, and consistency based on real-time soil data, allowing for precise nutrient supply tailored to the specific conditions of each potato ridge, including the use of mixed fertilizers and variable application lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spreading machine spreads fertilizer uniformly over the entire arable land, then the fertilizer distribution is even across the field, but the varying soil conditions within different areas lead to uneven tuber growth and reduced yield
Solution Approach 1:
The patent applies local quality by dividing the arable land into multiple sub-areas with different soil structures and quality characteristics, and applying fertilizer specifically tailored to each sub-area's needs. The system uses GPS-controlled portioning devices to deliver different fertilizer quantities and compositions to different locations, ensuring that each area receives the optimal fertilizer treatment for its specific soil conditions, thereby resolving the contradiction between uniform distribution and variable yield.
2Reliability
If fertilizer is applied in large quantities to ensure sufficient nutrient supply, then nutrient deficiency is avoided, but cost increases and environmental harm occurs due to oversupply
Solution Approach 1:
The patent implements feedback by using GPS-controlled portioning devices that can be regulated based on real-time or pre-assessed soil conditions. The system receives information about soil structure and quality from different areas and adjusts fertilizer application rates accordingly, ensuring that each area receives the precise amount needed. This feedback mechanism eliminates both nutrient deficiency and oversupply, optimizing fertilizer use efficiency and reducing waste.
3Ease of operation
If a standard fertilizer composition is used across all areas, then the application process is simple, but the varying soil structures and quality requirements are not met, leading to uneven growth
Solution Approach 1:
The patent applies dynamics by making the fertilizer composition and application rate variable rather than fixed. The GPS-controlled portioning devices can dynamically adjust the type, amount, and distribution of fertilizer based on the specific soil conditions of each sub-area. This dynamic adaptation allows the system to maintain operational simplicity while achieving precise, location-specific fertilizer application that promotes uniform tuber growth across varying soil conditions.
4Productivity
If fertilizer is applied without considering specific soil conditions, then the application process is fast and simple, but tuber deformities and malformations occur due to inappropriate dosing
Solution Approach 1:
The patent applies preliminary action by pre-assessing and mapping the soil structures and quality characteristics of different areas before fertilizer application. This preliminary information is stored and used to guide the GPS-controlled portioning devices during the actual fertilization process. By preparing the soil condition data in advance, the system can quickly apply the appropriate fertilizer doses without compromising application speed, while ensuring that each area receives the correct treatment to prevent tuber deformities and malformations.

AI summary
In a method for applying fertilizer in potato cultivation, a fertilizer (6) in liquid, gaseous, or solid form is introduced in the area of the respective seed tubers (2) to be planted in potato ridges (8, 8', 8''), beds, or similar soil forms of agricultural land (3). A structure comprising one or more fertilization lines (9, 10, 11) can be created in the longitudinal direction of potato rows. The concept according to the invention provides that a fertilizer (6), which is variable at least in its composition, quantity, consistency, and/or distance from the seed tuber (2), is supplied to the immediate vicinity of the seed tubers in a site-specific manner (BW, BW').The device (7) provided for this purpose has a dosing unit (12) that can be connected to at least two storage containers (5), so that the fertilizer (6), which can be mixed from at least two fertilizers (13, 14) therein, can be transferred to the potato ridge area via a feed system (15) that can be divided into sections. A computer-aided control unit (16, 16') is used to adjust the direct discharge of fertilizer(s), the mixing of fertilizers, and/or the dosage of the fertilizer discharge in fertilization lines for specific areas.
