The content of organic matter in the topsoil of different soil textures is quite different. Loamy soil has the highest organic matter content, with an average of 9.90g/kg; sandy soil has the lowest organic matter content, with an average of 9.51g/kg. The maximum value of organic matter is 22.6g/kg, which appears in loamy soil; the minimum value is 3.6g/kg, which appears in sandy soil. The organic matter content of different soil textures from high to low is: loamy>sandy. <br>Different loamy soils also have different organic matter content. The middle loamy soil has the highest organic matter content, with an average of 10.67k/kg; the second is light loamy soil, with an average of 10.42g/kg; and the sandy loam soil has the lowest content, with an average of 9.29g/kg. The organic matter of different loamy soils from high to low is: middle loam>light loam>sand loam

The organic content of soil in the soil of different soil texture and tillage layer is different. The soil soil organic matter content is the highest, with an average of 9.90g/kg, and the sand soil organic matter content is the lowest, with an average of 9.51g/kg. The maximum organic matter is 22.6g/kg and appears in the soil, and the minimum value is 3.6g/kg, which appears in the sand soil. The organic matter content of different soil texture is from high to low in order: soil quality and sand quality.<br>There were also differences in the organic content of different soil soil, with the highest organic content of the middle soil, with an average of 10.67k/kg, followed by light soil, with an average of 10.42g/kg, and the lowest content of sand soil, with an average of 9.29g/kg. The organic matter of different soil soil is from high to low in turn: the middle soil and the sand soil

The organic matter content of plough layer soil with different soil texture was different. The organic matter content of loamy soil was the highest, with an average of 9.90g/kg; that of sandy soil was the lowest, with an average of 9.51g/kg. The maximum value of organic matter is 22.6g/kg in loamy soil, and the minimum value is 3.6g/kg in sandy soil. The order of organic matter content in different soil textures was loamy > Sandy.<br>The content of organic matter in medium loam soil was the highest with an average of 10.67k/kg, followed by light loam with an average of 10.42g/kg, and sandy loam with an average of 9.29g/kg. The order of organic matter in different loamy soils was: medium soil > light soil > sandy soil<br>
