“…But compared to nitrogen and phosphorus, potassium is often absorbed by plants at an earlier stage of growth. 36 A very high potassium content can be seen in the southern region of Phansidewa block whose value ranging from 52. 78…”

“…Additionally, it has significant effects on a wide range of other quality variables, such as grain shape as well as colour, size of the tuber, oil content, the amount of dry matter & starch content, sugar content, fruit ripeness, and quality. 36 Therefore, it is hardly unexpected that crops suffer substantially in difficult growing seasons when they lack plant-available potash. Weaker, less vigorous crops are the result.…”

Soil surveying and mapping are extremely important in order to comprehend the characteristics of soil and what applications there are in agriculture, irrigation, urbanisation, and other land uses purposes. A major hindrance to the maximum production of the land is soil degradation brought on by inappropriate land management techniques. Geographical variability mapping of soil parameters is necessary for the agricultural productivity, food safety and environmental modelling. This research was done to identify some of the soil characteristics in the Siliguri Sub-Division. The present study had been conducted in the four blocks of Siliguri Sub-Division, located at the foot hill of the Darjeeling Himalayas in the Terai region of West Bengal, India. To comprehend the geographic variability of soil characteristics using a geospatial technique Soil pH, Phosphorus (P), Organic Carbon (OC), Nitrogen (N), Sulphur (S) and Potassium (K)were measured. To evaluate the current soil status of the area, some important chemical characteristics of the soil were identified. Geographic Information System (GIS) techniques were used to create surface maps of soil attributes, and sampling-broad analysis utilizing GPS was found to be a potentially effective tool. The goal of the study is to use an innovative method to carry out a soil analysis in a newly developed area. The production of digital maps for soil attributes allowed GIS to be used in the study to portray the laboratory results of the soil analysis. Utilizing variable technology, such digital mapping can be utilised in the research on agricultural applications. The result obtained from the research portray that the soil is acidic in nature and the pH value ranges between pH 6.1 to pH 4.5. Moreover, the presence of Nitrogen is between 0.13 to 1.90 %. Organic Carbon ranges between 2.22 to 1.47 %. The range of Potassium is between 32 ppm to 58 ppm, Phosphorus ranges between 09 to 27 ppm and sulphur content ranges between 10.4 to 32.3 ppm. The investigations will assist the development of a sustainable ecological status and proper agricultural system. Subsequently, it will also help to local government, environmentalists, LULC planners to promote any developmental plan related to agriculture and soil in the Siliguri Sub-division.

“…However, there is little published work on the effects of above adequate N and P fertilization on seed yield or physiological qualities. Environmental degradation from excessive fertilizer application has attracted attention due to eutrophication and nitrate contamination of water bodies, ammonia volatilization and subsequent deposition to neighboring ecosystems, and the greenhouse effects of nitrous oxide emissions (Stamatiadis et al 2016;Zhao et al 2022). E cient crop management will require an understanding of N and P balance to improve growth and increase yields, while reducing environmental impacts (Khodabin et al 2022).…”

Purpose Crop production in saline-alkali soils is often challenged by excessive fertilization, that can increase carbon equivalent emissions, and also by inadequate soil quality, thereby threatening sustainability. Previous researches on fertilization management focused on the short-term effects of single application of nitrogen (N) and phosphorus (P). Little is known about the long-standing effects that combined N and P fertilizers on seedling growth and crop yields. Thus, specific knowledge regarding the interactions between N and P fertilizers management practices targeting improved system sustainability on crop yield and quality.Methods Using combinations of 18 levels of N fertilizer and 16 levels of P fertilizer, we conducted multi-factorial, orthogonally-designed field experiments with large sample sizes for three years to determine the optimal ratio of N and P for germination, seed yield, seedling growth and yield components of six grasses. Results We calculated the mode of the physiological traits and used the thickest value as the optimum, and found a significantly antagonistic interaction between N and P for seedling growth traits, seed components and seed yields when the N: P ratio was between 2 and 3, with the optimal N: P ratio being 2.86:1. And the plants treated with high N and low P had higher values for physiological traits, seed components and seed yields, and strongly promoted vegetative/reproductive growth of seedlings. Conclusion These results can be applied to develop breeding strategies and quality detection in saline-alkali environments that contain soil with low availability of N and P.
