Controlled-Release NPK Fertilizer Encapsulated by Polymeric Membranes
The business granular fertiliser NPK6-20-30 was coated exploitation polysulfone (PSF), polyacrylonitrile (PAN), and cellulose ester (CA). The coatings were fashioned from the compound solutions by the section inversion technique. Measurements of the thickness and consistency of the ready coatings and a microphotographic observation of the coatings were performed. The physical properties of the coatings influence the discharge rate of macronutrients that area unit gift within the core of the coated fertiliser. [1]
Microbial biomass C, N and P in two arctic soils and responses to addition of NPK fertilizer and sugar: implications for plant nutrient uptake
The soil microorganism carbon (C), element (N) ANd phosphorus (P) pools were quantified within the organic horizon of soils from an arctic/alpine low-altitude heath and a high-altitude fellfield by the fumigation-extraction methodology before and when factorial addition of sugar, NPK fertiliser and benomyl, a antimycotic agent. In unamended soil, microorganism C, N and P created up three.3–3.6%, 6.1–7.3% and 34.7% of the whole soil C, N and P content, severally. The inorganic extractible N pool was below zero.1% and also the inorganic extractible P content slightly but I Chronicles of the whole soil pool sizes. [2]
Long–term responses to factorial, NPK fertilizer treatment by Alaskan wet and moist tundra sedge species
At 13 sites in northern and central Alaska, full factonal and partial factonal NPK chemical experiments were completed in wet and dampish tundras the results of the fertilizers on N and P concentrations in leaves, leaf mass per tiller, tilling, and flowering of the dominant swamp plant species (Eriophorum vaginatum.

Interactive effect of gibberellic acid and NPK fertilizer combinations on ramie yield and bast fibre quality
Understanding the consequences of various mixtures of atomic number 7 (N), phosphorus (P) and metallic element (K) fertilizers and also the effects of GA3 (gibberellic acid) foliar spray on the fiber quality and yield of false nettle area unit necessary for maximising the quantity of those plants. 3 pot experiments were conducted victimization low NPK (140:70:140 kg/ha), traditional NPK (280:140:280 kg/ha), and low NPK + GA3 (10 mg/L) treatments.

Effect of NPK Fertilizer and Animal Manure on Some Biometric Parameters of Irish Potato Solanum tuberosum L. in Bougham, West Region Cameroon
Aim: The aim of this study was to guage the influence of NPK-based fertilizers and animal fertilizers on some biometric parameters of potato within the Western Highlands of Cameroon.
Place and Duration: The study was conducted in Bougham, a village within the Western Highlands of Cameroon. The seeds were seeded on the fourth of could 2016. gather was wiped out August 2014. [5]
