Soil NPK and Moisture analysis using Wireless Sensor Networks

International Conference on Computing Communication and Networking Technologies, 2020
Agriculture plays a vital role in the economic development of our country. Crop yield primarily depends on soil fertility and moisture level. Fertilizers are normally recommended based on the nutrient present in the soil.

Carbonaceous microsphere‐based superabsorbent polymer as filler for coating of NPK fertilizer: Fabrication, properties, swelling, and nitrogen release characteristics

Journal of Applied Polymer Science, 2020
Recently, the use of controlled release fertilizers in agriculture has resulted in huge benefits in plant growth and cultivation. Superabsorbent polymer (SAP)‐coated fertilizers have the added advantage in retaining water in soil after irrigation and ...

Uvođenje čistije proizvodnje na postrojenjima NPK-1 i MAP/NPK-2

2002
U Petrokemiji se proizvode NPK gnojiva na dva postrojenja NPK-1 i MAP/NPK-2. Nakon provedene analize oba procesa predložene su mjere čistije proizvodnje prema slijedećim kriterijima: A) mjere koje ne zahtijevaju investicije B) mjere čiji se povrat investicija očekuje unutar 6 mjeseci C) mjere koje zahtjevaju veće investicije i čiji se ...

Caking Processes in Granular NPK Fertilizer

Industrial & Engineering Chemistry Research, 1998
This investigation into the caking of granular NPK fertilizer examines three specific areas, namely, accelerated caking tests, the role of unbound water, and the effect of ammonium chloride on caking. The caking propensity of granular fertilizer was characterized by two accelerated caking tests, with the caking propensity being correlated with the ...

Yield, content and nutrient uptake by winter wheat and spring barley in response to applications of digestate, cattle slurry and NPK mineral fertilizers

Archives of Agronomy and Soil Science, 2019
Digestate represents an alternative source of nutrients for crops in sustainable agriculture. We aimed to evaluate the effects of digestate fertilization on grain (GY) and straw yield (SY) and nutrient content and uptake in winter wheat (WW) and spring ...

Controlled-Release NPK Fertilizer Encapsulated by Polymeric Membranes

Journal of Agricultural and Food Chemistry, 2002
The commercial granular fertilizer NPK6-20-30 was coated using polysulfone (PSF), polyacrylonitrile (PAN), and cellulose acetate (CA). The coatings were formed from the polymer solutions by the phase inversion technique. Measurements of the thickness and porosity of the prepared coatings and a microphotographic observation of the coatings were ...

Compression testing of granular NPK fertilizers

Nutrient Cycling in Agroecosystems, 1997
The crush strength of granular NPK fertilizer has been accurately determined using Instron compression testing equipment. Stress-strain analysis shows a distinctive break point followed by break up of granule fragments. The force required to crush the granules is a function of the granule diameter but the calculated pressure required to crush each ...
