NPK macronutrients and microRNA homeostasis [PDF]

open access: yesFrontiers in Plant Science, 2015
Macronutrients are essential elements for plant growth and development. In natural, non-cultivated systems, the availability of macronutrients is not a limiting factor of growth, due to fast recycling mechanisms. However, their availability might be an issue in modern agricultural practices, since soil has been frequently over exploited.

Analisis Spesifisitas Terhadap Sensor NPK

open access: yesIJEIS (Indonesian Journal of Electronics and Instrumentation Systems), 2023
Insufficient use of fertilizers results in non-optimal plant growth, while excessive use is wasteful and results in pollution. Sensor usage is one method for measuring the nutrient content in the soil so that the fertilization process can be carried out precisely. Accuracy, precision, and error are commonly used in analyzing sensor quality.

Statistics of Merging Peaks of Random Gaussian Fluctuations: Skeleton Tree Formalism [PDF]

open access: yes, 1999
In order to study the statistics of the objects with hierarchical merging, we propose the skeleton tree formalism, which can analytically distinguish the episodic merging and the continuous accretion in the mass growth processes.

PROSES PENGERINGAN NPK BERDASARKAN EVALUASI ROTARY DRYER DAN KADAR AIR NPK DI PT. PETROKIMIA GRESIK

open access: yesJurnal Rekayasa Mesin, 2023
Drying is an important process in the production of NPK fertilizers. The average NPK water content in August 2021 – January 2022 was 1.64%, still exceeding a good NPK water content of < 1.5%. The high NPK moisture content resulted that review are needed in drying process through rotary dryer evaluation and observation by creating multiple linear ...
