“…In contrast, straw returning to the field can improve organic matter content and straw decomposition rate. The amount of soil organic matter (SOM), which is carbon-containing organic matter in the soil, is a key indicator of both soil fertility and soil degradation status [2]. Therefore, rapid and accurate monitoring of SOM is of great importance to maintain soil fertility and sustainable agricultural development [3,4].…”

The rapid inversion of soil organic matter is of great significance for agricultural soil testing and fertilization in order to protect and utilize land resources effectively. This study selected the developmental base in Lishu County with typical characteristics of China’s black soil as its research area. This study established a 600 nm “bow curvature difference” spectral index and the partial least squares regression model, and the accuracy of their results was compared. The correlation between the 600 nm “bow curvature” spectral index and the soil organic matter of straw cover no-tillage is analyzed. The average soil organic matter content in the study area was 16.67 g·kg-1, and the organic matter increased significantly from NT-0 to NT-100 by 16.26 g·kg-1. The study provided a deep insight to improve the quantitative inversion methods to estimate soil organic matter.

China is a huge agricultural country with rich straw resources. However, the problem to be solved urgently is to find means to use crop straw effectively and reasonably. To study the influence of no-tillage straw mulching measures on soil compactness and soil organic matter, taking the black soil straw mulching no-tillage test field in Gaojia Village, Lishu County, Jilin Province as the research object, the characteristics of soil compactness and organic matter in different tillage layers under different cover years of no-till straw are discussed. The results show the following: (1) in the 0–50 cm tillage layer, the highest treatment method of soil organic matter is NT1 (no-tillage corn stover mulching for one year), with an average value of 2.62%, and the soil organic matter content of NT1 treatment increased by 57.46% compared with RT (ridge tillage). (2) The compactness of surface soil (0–20 cm) no-tillage soil is higher than RT, with an increase of more than 6.87%, and the compactness of deep soil (20–50 cm) no-tillage soil is lower than RT, with a decrease of more than 23.48%. (3) No-tillage can improve the agglomeration structure of the surface soil, increase the moisture content of the surface soil, reduce the volume of the surface soil, and improve the organic matter content of the surface soil, thus increasing the firmness of the surface soil. This study can provide a theoretical basis for promoting the comprehensive utilization of straw resources and developing eco-agriculture.
