Reclaiming Saline Soils: The Science Behind Oats & Wheat Yield Boosts

Challenges of Saline Land in China

Salts may accumulate on the soil surface when they are unable to leach out of the root zone. Additionally, plants can suffer from salt damage or toxicity. In saline and saline-sodic soils, elevated levels of soluble salts decrease the amount of water available for plant use.

Saline Land Remediation: Background Introduction

• The western region of Jilin City in China belongs to mild saline-alkali dryland soil, which has saline-alkali barrier and drought climate, resulting in low yield and low quality of crops.

• Developing industrialization production mode of low yield saline-alkali dryland is a necessary way to promote rural revitalization in western Jilin

• Flushing and Leaking is one of the most effective methods for improving saline-alkali land. The topsoil salt content can be desalinated, phreatic water level can be reduced and the surface accumulation of  soil salt can be alleviated by spraying salt with groundwater.

Wheat & Oatmeal plantation on Saline Land, North China

KhaiEL tackles saline soil challenge in Jilin, China, achieving remarkable wheat harvest despite harsh conditions.

KhaiEL successfully cultivated wheat on a barren and saline plot in Jilin, China, under extreme climatic conditions, achieving a harvest yield of 288 kg per China mu, significantly surpassing the conventional standard yield of 203 kg/mu.

Saline Land Remediation Process

Sinochem Environment's saline-alkali soil management team used the special soil remediation materials provided by KhaiEL, which reduced soil salinity, improved crop salt tolerance, and achieved a record of two harvests in one year (wheat in the first half and winter wheat in the second half), increasing the yield per unit area.

Land that had never been supplemented with high-quality soil nutrients, after absorbing a variety of essential elements, quickly rewarded human cultivation with lush, green crops.

While agricultural technology addresses technical challenges, repairing large-scale saline-alkali lands requires complex cost calculations, savvy management, and ample human resources. Only through comprehensive coordination across all aspects can the full restoration be achieved.
