Climate change to disrupt soil nutrients in drylands
The increased aridity expected this century as a result of climate change may disrupt the balance of key soil nutrients with a knock-on effect on soil fertility threatening livelihoods of more than two billion people, a study finds. The drop in nitrogen and carbon concentrations that occurs as soils become dryer could have serious effects on ecosystem services such as food production, carbon ...

Increasing aridity will disrupt soil nutrient cycles in global drylands
The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth’s land surface, according to new research. The study focused on ‘drylands’ – arid areas with low levels of rainfall – which support over 38% of the world’s population. Such nutrient imbalances could diminish the provision of ecosystem services, such as ...

Salmon provide nutrients to Alaskan streambanks
Adult Pacific salmon spend a great portion of their life in the ocean. But their life began along the banks of freshwater streams. Their life will end there, as well. These important steps in the lifecycle of salmon play a role in the health of streambank ecosystems. David D’Amore and a team of scientists studied how different soils respond to the delivery of “salmon-derived ...

Sandwich system found effective in organic apple orchards
In organic apple orchards, one of the most serious challenges for growers is determining ways to limit weed competition while improving soil quality and ensuring high yields of quality apples. Scientists from the Swedish University of Agricultural Sciences published a study of orchard floor management systems (HortScience, March 2015) that revealed the benefits of using "sandwich systems" in ...

Liquid corn, fish fertilizers `good options` for organic blackberry production
Managing soil nutrients in organic production systems presents multiple challenges for fruit growers. The availability and release rate of nitrogen from organic fertilizers, ease of application, and cost are among the important factors that influence choices in organic production. The authors of a new study say that there has been limited information available about the influence of fertilizer ...

Vermicompost leachate improves tomato seedling growth
Worldwide, drought conditions, extreme temperatures, and high soil saline content all have negative effects on tomato crops. These natural processes reduce soil nutrient content and lifespan, result in reduced plant growth and yield, and ultimately translate to lower profits for tomato producers. As an alternative to unsustainable practices such as the use of synthetic fertilizers, producers are ...

Four risks of using fertilizer
Fertilizers are increasingly popular because they successfully support plant growth and increase the yield. But what are the dangers of overusing fertilizers? Did you know that too much fertilization might cause “fertilizer burn”? Read below more about the negative effects of using fertilizer without knowing your soil’s nutrient needs. No optimal yield due to under- or ...

Preserve, promote, and utilise rich soil life
Healthy soil life can contribute to sustainable agriculture which, in addition to ensuring a good yield, keeps diseases under control and generates carbon and nitrogen retention. That is what Prof. Gerlinde De Deyn, Professor holding a personal chair in Soil Ecology, asserted in her inaugural address at Wageningen University & Research on 18 May. Life underground is richer in species than ...

Jatropha can revive degraded land, says study
Large-scale cultivation of Jatropha – known as a potential source of biofuel – can improve the soil quality of degraded lands and address climate change, says a new study. Jatropha curcas seeds yield oil that can be processed into biodiesel, but scientists at the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad, have found that Jatropha plantations ...

10 Frequently Asked Questions about soils
Why are soils important? Soils are the basis of life for a large number of plants and animals. Next, to their importance for biodiversity, soils are the essential substrate on which most agricultural plants grow. It means that this is where the food we eat comes from. In addition to that, soils play an important role in the structuration of the ground, which is essential for any sort of ...

Supplying sulfur to your crops
Sulphur is a key component when growing high yielding, healthy crops. Whilst Nitrogen is a growth promoter, Sulphur works as a growth regulator, effectively balancing the manufacture of sugars and proteins in leaf tissue with the demand from these materials throughout the plant. Consequently, Sulphur plays a crucial role in maintaining green leaf area, growth rates and delaying senescence. Low ...

Balancing Act: Reconciling the Laws of Minimum and the Maximum
Does going to the extreme in fertilizer application overcome yield limitations? When it comes to plant development and yield, imbalance is more likely to threaten soil health, production and your pocketbook. Instead, achieving nutrient balance is crucial to crop success. With that in mind, we reflect on the often-perceived conflicting theories – Liebig’s Law of Minimum and ...
