Protecting Black Soil for a More Secure National Granary
Original Title: Protecting Black Soil for a More Secure National Granary
“We must take effective measures to protect the black soil, which is the ‘giant panda of cultivated land,’ and preserve it for future generations.”
— July 22, 2020, emphasized during an inspection in Jilin
How to balance the protection and utilization of black soil has been a constant concern.
“This work is very important!” emphasized during the July 2020 inspection in Jilin, “Northeast China is one of the world’s three major black soil regions, known as the ‘Golden Corn Belt’ and ‘Home of Soybeans.’ While black soil is highly productive, it also faces issues of fertility depletion. We must take effective measures to protect this ‘giant panda of cultivated land’ and preserve it for future generations.”
This golden autumn brought good news from the black soil region: In Baiquan County’s Xinsheng Township, Yongfa Village, Heilongjiang Province, a previously eroded gully area now yields “ton-grain fields” — with corn production exceeding 1,000 kilograms per mu! Before treatment in 2021, the yield was only 300 kilograms per mu.
Erosion gullies, formed by heavy rain erosion, consume farmland and fragment fields. Heilongjiang Province has 115,500 erosion gullies totaling 45,000 kilometers in length.
The 2025 Central Document No. 1 proposed “strengthening erosion gully treatment in Northeast China’s black soil region.” To treat Yongfa Village’s 2,810-meter-long erosion gully, Baiquan County invested 3.8 million yuan, implementing slope cutting, stone cage construction, and shrub planting, reducing the 20-meter-deep gully to 5 meters.
“‘Fragmented land’ has been restored to ‘whole fields,’ and the black soil that had become thinner, poorer, and harder in recent years now glistens with richness again,” said Yongfa Village resident Yang Weijie, holding a handful of soil. Of Old Yang’s 120 mu of farmland, nearly 50 mu bordered erosion gullies, all of which have now been treated and reclaimed.
It was pointed out: “The foundation of grain production lies in cultivated land, its lifeline in water conservancy, its future in technology, and its driving force in policy. These key points must be implemented one by one and carried through to completion.”
During the “14th Five-Year Plan” period, 14.406 billion yuan in central funds were allocated to Northeast China’s black soil region, treating 57,300 developing erosion gullies, protecting approximately 13.74 million mu of farmland, and increasing annual grain production by about 330 million jin.
Covering black soil with “blankets” — straw returning subsidies of 20 yuan per mu; “loosening the soil” — deep plowing subsidies of 30 yuan per mu; letting black soil “breathe” — crop rotation subsidies of 150 yuan per mu… Over the year, Old Yang received nearly 20,000 yuan in various black soil protection subsidies.
Through storing grain in the land and technology, Old Yang also benefited from soil testing and formulated fertilization services, allowing the black soil to “eat” balanced nutrient meals. In 2024, the average organic matter content in Heilongjiang Province’s soil reached 40.3 grams per kilogram, an increase of 4.1 grams per kilogram from 2016.
“Black soil generates ‘gold,’ stimulating farmers’ internal motivation,” said the Director of Water and Soil Conservation at Heilongjiang Provincial Water Resources Department. Baiquan County is the only national high-quality water and soil conservation development pilot zone in Northeast China’s black soil region and also serves as a grassroots research point.
Accompanying the Songliao Water Resources Commission research team, walking along field ridges to understand local needs. In 2024, additional national bond funds supported the treatment of 27,700 erosion gullies in Northeast China’s black soil region, equivalent to the total workload of the past decade. Since treatment cannot rely entirely on allocations, many areas are exploring ecological product value transformation. Addressing challenges in valuation,抵押, and monetization, the research team reported local demands to relevant departments, receiving prompt responses.
“Ministry-province coordination and central-local collaboration are paving new paths for black soil protection,” said the Director of Monitoring and Evaluation at the Department of Water and Soil Conservation. From May to June last year, accompanying an inspection team to Heilongjiang to conduct field research on erosion gully treatment, and based on
