Boosting phosphorus levels leads to thriving root growth in wheat and soybean
Phosphorus levels affect root growth in spring wheat and soybean intercropping. Phosphorus boosts root growth in both plants, leading to higher root weight in intercropping compared to monoculture. Wheat roots grow more in the upper soil layer when lacking phosphorus. Acid phosphatease activity in roots increases without enough phosphorus. Soil pH is lower in soybean monoculture than in wheat-soybean intercropping.
