- Determination of soil nutrients (NPK) using optical methods: a mini review
26 cze 2024 · In-situ measuring of the N, P, and K nutrients is recommended because it allows for more accurate soil mapping nutrients variability for variable-rate fertilizer management and has the possibility for a higher measurement density at a comparatively low cost.
16 lut 2021 · This paper reviewed optical methods of soil nutrient detection suitable for building a portable sensor because it can sense nutrients in dry soil samples directly without the need for...
21 lut 2024 · In this review, we have evaluated several methods and recent technologies to determine the soil NPK content to increase yield production.
1 cze 2023 · In terms of plant requirements, N ranks first, followed by P and K. They are essential nutrients for plant growth and development because nearly all plants use them throughout their life cycles (Samuel and Ebenezer, 2014; Mahmud et al., 2020). An adequate proportion of N, P, and K functions in plant nutrition synergistically to promote healthy ...
27 lut 2024 · Moreover, the designated application amounts of N, P, and K of chrysanthemum set at N (330 kg⸳ha −1), P (196 kg⸳ha −1), and K (450 kg⸳ha −1) were suitable dosages for chrysanthemum. In general, the chrysanthemum crop response to fertilizer application improved antioxidant attributes.
31 sie 2021 · All you need to know about using NPK fertiliser, including when, why and how. Plants require a range of nutrients for healthy growth. These nutrients occur naturally in the soil and can also be added in the form of fertilisers, to boost growth rates, performance, and crop yields.
