• Can Exogenous Nitrogen Inputs Impact on Mycorrhiza in Karst Grassland?

  The simulated N deposition experiment (N, 100 kg N ha-1 yr-1; P, 50 kg P ha-1 yr-1; NP, 100 kg N ha-1 yr-1 + 50 kg P ha-1 yr-1) and different legume species (Amorpha fruticose vs Indigofera atropurpurea) or planting densities (1.5 × 2 vs 1 × 1 m) in the grassland were set up at the Institute of subtropical agricultural (ISA) of the Chinese Academy of Science (CAS). Researchers measured the AMF abundance and community composition, as well as soil properties.

  Whether Rice Straw is Efficient to Reduce N2O Emission?

  Researchers found that rice straw (RS) treatment increased 131.5% of N2O emission factor from low strength CWs, but decreased 37.2–43.7% of N2O emission factors for medium and high strengths compared with no rice straw (NRS) treatment.

• Carbon Allocation in Rice–soil Systems Affected by Plant Age, Chase Period and Nitrogen Input During Crop Growth

  In order to accurately trace allocation of photosynthate carbon depending on plant age and chase period in nitrogen-fertilized and non-fertilized rice-soil systems, and during crop growth, estimating the net plant-derived carbon input to belowground, researchers from the Institute of Subtropical Agriculture (ISA) of the Chinese Academy of Sciences (CAS) and University of Goettingen conducted an pot experiment in Lab using fresh topsoil (0-20 cm) of a rice field after removing roots and plant residues. All the pots were fertilized by base phosphorus (P) kalium (K) fertilizers, with rhizosphere and bulk soils separated by rhizosphere bag.

• How Alkaline Phosphomonoesterase-harboring Microorganisms Contribute to P Mineralization in P-depleted Soil?

  The role of the key alkaline phosphomonoesterase (ALP) -encoding gene (e.g. PhoD) in the regulation of soil P turnover is remains poorly understood. To study this role, a team of work from the Institute of Subtropical Agriculture (ISA) of Chinese Academy of Sciences in cooperation with Institute of Plant Nutrition and Soil Science, Christian-Albrechtes-University of Kiel, Kiel, Germany and University of Firenze, Italy collected P-poor paddy soil.
