What is the desired amount of NPK in compost?5 answersThe desired amount of NPK in compost varies depending on the specific crop and soil conditions. In the study by El-Tahlawy et al., it was found that a medium dose of NPK fertilizers (75% of the recommended dose) combined with processed compost resulted in improved growth and productivity of wheat plants. Fratoni et al. reported that the sole use of organic compost mixed with sand was sufficient for adequate yield of yellow pitaya, indicating that no additional NPK fertilizer was needed. Rofner et al. found that the addition of compost reduced the cadmium content in cocoa almonds, but did not specify the NPK content of the compost. Zimin et al. provided a method for optimizing the phosphorus content in compost, but did not mention specific NPK ratios. Kumar et al. demonstrated that the integrated use of NPK-enriched bio-compost and inorganic fertilizers resulted in improved rice yield, but did not specify the desired NPK ratio in the compost. Therefore, the desired amount of NPK in compost may vary depending on the specific crop and soil conditions, and further research is needed to determine optimal ratios.

How does NPK fertilizer help with the growth of brassica napus?5 answersNPK fertilizer helps with the growth of Brassica napus by enhancing the morphological characteristics of its pollen grains, leading to improved yield and quality. The use of organic fertilizers and zeolite significantly enhances the morphometric parameters of pollen grains, such as the polar axis, equatorial diameter, shape index, and perimeter of perforation zones. Potassium fertilizers, specifically potassium chloride, have a significant effect on canola yield, capsule in plant, seed yield, and oil content. Different rates and timing of nitrogen (N) fertilizer application, including side-dressed N application, result in improved seed yield, protein concentrations, and oil yield. The depth of fertilizer banded-placement in the soil also affects the growth, nutrient uptake, and yield of oilseed rape, with 10 cm and 15 cm deep fertilization being recommended for oilseed rape production. Foliar N application at the end of flowering increases seed yield, although it reduces seed oil concentration and increases seed protein concentration.
