Currently, Agricultural science is advanced. Unfortunately, precise nutrient management is not implemented by all the farmers, but most of the farmers are doing annual soil tests. we need crop-specific and location-specific nutrient recommendations (like STCR equation). A precise Fertilizer recommendation for crops is required.
Fertilization can be done in several ways.
Fertilization is applied with VRT variable rate technology.
However, mineral fertilizers are applied.
Peat, bird manure, are not precisely applied to the soil.
Because the exact application of such fertilizers is very difficult.
Precision fertilization is applying the Right Input, at the Right Amount, to the Right Place, at the Right Time, and in the Right Manner and help farmers reduce the amount of inputs they use, which can help reduce the risk of environmental pollution. Precision agriculture is the science of improving crop yields and assisting management decisions using high technology sensor and analysis tools. Precision fertilization and precision irrigation are a fertilization technology based on the comprehensive analysis of the yield data of different spatial units and multilayer data, such as soil physical and chemical properties, diseases, pests, and climate. A fertilizer recommendation is the research-based set of guidelines, or management practices, for supplying fertilizer to the crop to achieve yield and quality goals (economic) in a manner that minimizes nutrient losses to the environment. High-spatial-resolution UAS imagery enables much earlier and more cost-effective detection, diagnosis, and corrective action of agricultural management problems compared to low-resolution satellite imagery. Therefore, UAS can address the needs of farmers or other users, enabling them to make better management decisions with minimal costs and environmental impact.

Doses of foliar fertilizers are smaller than those for the root system. It is usually recommended to add 0.5-2% fertilizer by weight of water (5-20 grams of fertilizer per liter of water)The 5 Rs of PA include: applying the Right Input, at the Right Amount, to the Right Place, at the Right Time, and in the Right Manner. The system involves four stages, i.e., soil analysis, data pre-processing, data analysis, and recommendation of fertilizer. The IoT-based device utilizing NPK sensor is used to calculate the NPK ratio of the soil sample. The data is formulated into a dataset. STCR approach is aiming at obtaining a basis for precise quantitative adjustment of fertilizer doses under varying soil test values and response for targeted levels of crop production. STCR provides the relationship between a soil test value and crop yield. There are three basic approaches to fertilizing plants with P and K: sufficiency, maintenance and build. The sufficiency approach recommends applying the minimum amount of fertilizer necessary to maximize yield in the current year. Crop Recommendation Systems (CRS) are computer-based tools that help farmers make informed decisions about which crops to plant based on factors such as soil type, weather patterns, and historical crop yield.
Absolutely! Agricultural science has indeed reached an advanced stage, but there's a gap between the available knowledge and its practical implementation, particularly regarding precise nutrient management in farming. While it's encouraging that many farmers are conducting annual soil tests, it's crucial to translate these tests into actionable insights that are tailored to specific crops and locations.
The Soil Test Crop Response (STCR) equation is one such tool that can provide farmers with precise recommendations for fertilizer application based on soil test results, crop type, and environmental factors. These recommendations ensure that nutrients are applied in optimal quantities and at the right time, maximizing crop yield while minimizing waste and environmental impact.
By embracing crop-specific and location-specific nutrient management strategies like the STCR equation, farmers can achieve more sustainable and efficient agricultural practices. This not only benefits their bottom line by reducing input costs and increasing yields but also contributes to environmental conservation by minimizing nutrient runoff and pollution.
Therefore, there's a clear need to prioritize the adoption of precise fertilizer recommendations in agriculture to harness the full potential of advanced agricultural science and ensure the long-term sustainability of our food production systems.
Today, the exact application of mineral fertilizers to plants is a very difficult and urgent issue.Mineral fertilizer spreaders (centrifugal machines) spread fertilizers unevenly on the soil.Therefore, there is still a great need for the development of the system of applying machines.Farmers face difficulties in the precise use of fertilizers.The productivity of VRT technology is very low.
Although map-based fertilization is sensor-based, physical mechanisms are not justified.Application of precision fertilizers in larger areas results in more stoppages and loading of fertilizers into the hopper.There is a greater need for the development of fertilizer spreaders with VRT technology.
