When Benson Wanjala started farming in his western Kenya village two and a half decades ago, his 10-acre farm could produce a bountiful harvest of 200 bags of maize. That has dwindled to 30. He says his once fertile soil has become a nearly lifeless field that no longer earns him a living.

Like many other farmers, he blames acidifying fertilizers pushed in Kenya and other African countries in recent years. He said he started using the fertilizers to boost his yield and it worked — until it didn’t. Kenya’s government first introduced a fertilizer subsidy in 2008, making chemical fertilizers more accessible for smaller-scale farmers.

Problems with soil health are growing as the African continent struggles to feed itself. Africa has 65% of the world’s remaining uncultivated arable land but has spent about $60 billion annually to import food, according to the African Development Bank. The spending is estimated to jump to $110 billion by 2025 due to increased demand and changing consumption habits.

“Inorganic fertilizers were never meant to be the foundation of crop production,” he said, later adding that because of “commercially inclined farming, our soils are now poor, acidic, and low in biomass resources, and without life!”

    This is what happened in North Korea. The widespread use of fertilizers to keep fields producing instead of leaving the soil to rest for a season or rotate crops to revitalize the earth caused the soil to become inhospitable to plants. That’s the crux of the NK famine that started in the 90s.

    Africa has history to learn from. Let’s hope there is change.

      No it’s not what happened to North Korea at all. I have no clue where you got that from.

      The collapse of the Soviet Union cutting off food, fuel, fertilizer, and technology support started it.

      Then torrential rainfall and flooding destroyed that years crop and food storage in the main production regions. It also destroyed many of their hydroelectric dams and irrigation systems. Without support from the soviets they had no way to repair them.

      However the main reason hundreds of thousands of not millions died was because of the governments unwillingness to open their borders for international aide/trade. The government deliberately starved their population.

        I got it from here, but then followed it up with some googling of NK agriculture and recipes. NK farms push soil too far, use industrial farming methods at the expense of local wisdom, and have no respect for nature - causing them to look like frail idiots who can’t sustain themselves without imports.
