World Soil Day Blog #10: Harvest Reflections and the Growth of Plastics

Emilee Severe, PhD Student, Lancaster Environment Centre


If you look out the kitchen window at my parent’s home you will see my mother’s pride and joy (and no it’s not me) it is a small patch of soil, her garden. As a growing girl, I spent hours in that garden, making rows, planting seeds, supporting my mother in her endless war against the weeds and of course the culmination of our summer’s labour, harvesting. I can remember small changes my parents made over the years to improve our bounty. As a little girl, I can vaguely remember using raised soil beds for the carrots. Then we moved to planting everything in ridges and furrows. Later, to suppress the weeds, we added grass clippings around the borders of the garden. I remember my dad creating all sorts of cages, stringed lines and stakes to help the tomato plants grow tall and fruitful.   Continue reading

World Soil Day Blog #9: You can’t teach old trees new tricks, or can you?

All human activities, from breathing to burning fossil fuels, emit carbon dioxide (CO2) to the atmosphere. Once the CO2 molecules are in our atmosphere, they absorb and radiate heat, and together with a group of other gases, they create the greenhouse effect. Because of this effect, we are able to live on this planet without freezing to death! However, because of the increases in our activities the concentration of atmospheric CO2 has been rapidly increasing, breaking a record high in 2021 [1] trapping more heat in the atmosphere and increasing global temperatures.   Continue reading

World Soil Day Blog #8: Ken-ya manage soils more sustainably?

Soil is fundamental to global food production, whether it be in the direct production of crops or providing feed to sustain livestock. The physical, biological, and chemical properties of soils have a defining influence on yield, which can make or break the ability of societies to put food on the table. Therefore, protecting our soils, whilst maximising output is an important balancing act. Continue reading

World Soil Day Blog #7: To P or not to P? The question for sustaining soybean soils

Soil plays a key role in all food production, with soils providing over 95% of food and mineral nutrition for human life [1]. My PhD research is focused on the role of soils and nutrients in soybean, with a focus on phosphorus (P). Soybean (Glycine max L. (Merr.)) is a globally important crop, with production levels today being 13 times higher than the 1960s [2]. Soybean, or soya as it is more commonly known, acts as the largest source of both vegetable oil and animal feed, as well as being a key component of vegan or vegetarian diets [3]. The demand for soya is continuing to increase, with 5% of the UK population now being vegan or vegetarian [4] contributing to demands of increased soybean production.

World Soil Day Blog #6: Unsung city soils – can they put more food on our plates?

In the hustle and bustle of a city, have you ever stopped to think about the soil under your feet? If not, you can be forgiven. Soils in urban places – be they villages, towns, cities, or suburbs – have often been overlooked by not only the general public, but also scientists. Continue reading

World Soil Day Blog #5: Soil loss – a future of scarcity?

Helena Ripley, PhD Student, Lancaster Environment Centre

I know the Jurassic Coast in Dorset and Devon well, an incredible landscape that fostered my interest in the environment from a young age. This part of the world introduced me to my first scientific hero, Mary Anning, and gave me a context from which to understand the cycles of the natural world. Continue reading

World Soil Day Blog #4: Tree methane – Getting to the root of it

 When you think of trees, you often associate them with providing oxygen, up-taking carbon dioxide (CO2) and playing a vital role in mitigating against global warming. Whilst all that is true, more recent discoveries have shown they emit methane (CH4), particularly in wetlands and peatlands across the world…

World Soil Day Blog #3: Plastics in farming – an emerging risk?

Nhu Phan, PhD Student, Lancaster Environment Centre

Have you ever walked by an agricultural field and noticed instead of plants stretching for miles you see rows and rows of plastics? Surprisingly as it may seem, that is just a small portion of the plastics being used on the farms. There are also plastics-coated seeds and fertiliser, the pipes irrigating the fields, and the packaging around the final products. Plastic also makes their way into biosolid fertiliser as well as municipal compost which is deliberately spread on the field. For years, plastic has become a key component in our modern agriculture.

World Soil Day Blog #1: No Soil = No Food

To celebrate World Soil Day on the 5th of December we have written a series of blogs that dig in (pun intended) to the many connections between soils and food. These blogs are inspired by our sustainable soils research at Lancaster and include a recipe that connects our soil research to the dinner plate! We are publishing a blog a day between 21st November and the 5th of December. We hope you enjoy digging into both our research stories and recommended recipes. Enjoy – bon appetit!
