TL;DR: In this article, the effects of different saline soil improvement treatments on the distribution of salt content in the soil profile and the effect of desalination were analyzed, and a profile salinity prediction model was built based on the EMI to simulate the threedimensional spatial distribution characteristics of soil salinity in the test area.

TL;DR: In this paper, a large-scale and accurate monitoring of soil salinization is proposed for controlling soil degradation and sustainable agricultural development in the agricultural irrigation area of the Manas River Basin.

TL;DR: In this paper, a drip irrigation cotton field nitrogen application management method based on a GIS is described, which comprises the steps that total nitrogen, organic matter and alkali-hydrolyzable nitrogen of soil are taken as data sources, partitioned management on drip irrigation Cotton field nitrogen nutrients is achieved through a fuzzy c-mean clustering algorithm, on this basis, the application amount of nitrogen base fertilizer is determined by taking the alkali hydrolyzeable nitrogen as an index, canopy NDVI critical values of all the duration periods of cotton are determined on the

TL;DR: In this paper, a farmland nutrient management partitioning method based on a GIS and an RS was proposed for determining the optimal phase for crop remote sensing yield estimation and obtaining remote sensing image data; obtaining an appropriate vegetation index by using Remote Sensing image processing technology; obtaining GPS position information and soil nutrient data of sampled soil; subjecting the collected cartographic information to cartographic scanning digitization and graph rectification.
