• How Soil Types Affect Fungal nirK-Containing Communities?

  Researchers from the Institute of subtropical agricultural (ISA) of the Chinese Academy of Science (CAS) investigated the abundance and composition of fungal nirK-containing denitrifiers across different climate zones in China, including quaternary red clay soils(QRC), alluvial soils(AS), and black soils(BS).

  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.

• C/P Ratio of Root-detritus Affects Distribution and Dynamics of Enzyme Activities in Root-detritusphere

  The important role of dying rice root (root-detritus) in advancing researchers’ understanding of nutrient cycling in paddy soil, has motivated scientists 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 Institute of Environmental Sciences, Kazan Federal University, Russia. to investigate how it can affect the distribution and dynamics of enzyme activities in root-detritusphere.

• 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.

• Can Rumen Cannulation Alter Ruminal Dissolved Gases and Methanogen Community in Dairy Cows?

  Researchers from China Agricultural University, the Institute of Subtropical Agriculture (ISA) of Chinese Academy of Sciences investigated the effects of rumen cannulation on ruminal dissolved gases and methanogenesis.Four cows were surgically fitted with rumen cannula, while the other four cows were left intact and used as control. Rumen gases and contents were collected 0, +2.5 and +6 h relative to the commencement of the morning feeding on d 41 and 42.

• Nitrogen Fertilizer Enhanced Dynamics of Rice Rhizo-C and its Allocation to Microorganisms in Paddy Soils

  To study how rice plants can significantly modify their soil environment (rice rhizosphere effect) through carbon rhizodeposits from roots into the surrounding soil, scientists from the Institute of Subtropical Agriculture (ISA) of Chinese Academy of Sciences in cooperation with Georg-August University of Gottingen, Germany and Australian Centre for Ecogenomics, School of Chemistry and Molecular Biosciences, University of Queensland,Australia installed an experiment.
