Buildup of phosphorus in agricultural soils due to nitrogen-based manure management can increase the risk of phosphorus loss from agricultural fields over time. Scientists Sadeghpour et al. demonstrated the long-term sustainability benefits of phosphorus removal based manure management of a dairy corn silage and alfalfa forage rotation. The work emphasizes the importance of rotation fertility management rather than single-year P management.

Seed conservation under tropical climates is a great challenge when usual storage technology is lacking. Seed pests and the loss of seed viability are among the main risks faced by farmers and seed banks. Scientists Lawrence et. al. recently found that vacuum sealing significantly reduces stored insect pest pressure while maintaining seed viability. Several local treatments decrease also pest pressure, thus constituting sustainable alternatives to storage under low temperature and low moisture.

Escaping the poverty trap and finding win-win paths that protect both the environment and economic development are challenging issues. Scientists Cao et al. propose a feasible plan to improve both the environment and life in Yanan City. The method involves the construction of terraced fields, establishment of fruit tree orchards, implementation of grazing restrictions, and ecological migration. This strategy exemplifies appropriate sustainable governance and development for other ecologically fragile regions.

Commercial oat cultivars produce higher yields in temperate regions than in dry and hot areas. Agronomists Sánchez-Martín et al. studied oat landraces and found that these wild relatives should outperform commercial varieties under harsh conditions.

Micronutrients provide multiple benefits in crops. In plants, part of these micronutrients is involved in plant-soil-water relations. A new article by Dimkpa and co-workers demonstrates the effects of using a micronutrient formulation of zinc, copper and boron in mitigating drought stress on soybeans. Micronutrients increased plants growth, yield and nutrient uptake. Such a strategy contributes to decrease fertilizer losses and to zinc fortification of food crops.

Ethiopia faces high risk of soil carbon depletion largely due to deforestation and continuous cultivation. Deforestation has resulted in losses of between 20 and 50 percent of the soil carbon stocks in the first meter of the soil depth. Scientists Berihu et al. studied the effect of land use-land cover changes on soil organic carbon and nitrogen. They found that the soil organic carbon sequestration and total nitrogen content for dense forest were significantly higher than that of grassland, open forest, and farm land. Conversion of forest to other land use may lead to massive losses in soil nutrients.

Soil erosion is a major issue for crop production, and is expected to increase with climate change. Measuring soil loss is difficult and few reliable methods are available. Agronomists Duan et al. designed a new method to calculate soil loss tolerance, taking into account soil productivity.

How to increase grain yield and decrease the impact of agriculture on climate? Liu et al. found in the literature seven key farming practices that increase crop yields by 15-59%, decrease carbon footprints by 25-34% and decrease greenhouse gas emissions by 25-50%.

Poultry producers are always seeking a more efficient chicken that will grow faster using fewer resources. But what are the consequences on the birds themselves? Scientists Tallentire et al. find that the improved efficiency of modern breeds is the result of increased growth rate, particularly of breast meat. They discuss the effects of artificial selection on traits such as metabolic activity. As industrial feed production has a huge environmental impact, is this progress in chicken genetics good news for global food sustainability?

Adaptation of farming management practices to changing environmental conditions, such as climate, is a major issue that controls the success or failure of food production. Therefore Robert et al. review how flexible management strategies are in farming decision models. They propose a sequential decision-making process.
