• Effects of Long-Term Material Amendments on Soil Phosphorus Fractions and Associated Microbial Changes in Greenhouse Tomato Cultivation (2026) · Agriculture · cited 4× · doi

  Intensive agricultural production leads to phosphorus fixation in soil. The deficiency of available phosphorus in the soil remains a key issue restricting the sustainable development of agriculture. The study faces the challenge of understanding the complex interactions between soil chemistry, phosphorus fractions, and microbial communities.
