Green manure crops for low fertility soils [PDF]

, 2019
Organic crop production is growing, but crop yields are still below potential. The purpose of our project “Nutrients for higher organic yields (NutHY)” is to increase yields and resource efficiency in organic crop production by optimizing nutrient supply.

Relationships between land use and nitrogen and phosphorus in New Zealand lakes [PDF]

, 2011
Developing policies to address lake eutrophication requires an understanding of the relative contribution of different nutrient sources and of how lake and catchment characteristics interact to mediate the source–receptor pathway.

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

Advanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

Balancing soil nutrient availability on commercial organic farms [PDF]

, 2006
Soils from two commercial farms were analysed for cation exchange capacities with the aim of improving the balance of available nutrients at soil level, and to support the basic organic principle of maintaining and improving the long-term fertility and ...

Bacterial Community Structure after Long-term Organic and Inorganic Fertilization Reveals Important Associations between Soil Nutrients and Specific Taxa Involved in Nutrient Transformations

Frontiers in Microbiology, 2017
Fertilization has a large impact on the soil microbial communities, which play pivotal roles in soil biogeochemical cycling and ecological processes.

Forecasting Root Rot Disease through Predictive Microbial Functional Profiling

Advanced Science, EarlyView.
Predicting soil‐borne disease moves beyond observation with a framework that elevates microbial functional genes into reliable forecasting biomarkers. By coupling targeted qPCR assays for core stress‐response genes with machine learning, this method detects root rot risks in pre‐symptomatic soils with over 80% accuracy.

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

Monitoring of soil EC for the prediction of soil nutrient regime under different soil water and organic matter contents

Applied Biological Chemistry
Smart farms and precision agriculture require automatic monitoring and supply of water and nutrients for crops, but sensors to monitor plant available nutrients in soil are not available.

Arsenic in Poultry Litter: Organic Regulations [PDF]

, 2005
Most of the arsenic used as an antibiotic in commercial broiler production ends up in the litter. Using this litter as a soil amendment is not prohibited by the National Organic Program, but 7CFR S205.203(c) of the Rule requires that "the producer must ...
