How long will it take for the world to run out of topsoil?

If we continue to degrade the soil at the rate we are now, the world could run out of topsoil in about 60 years, according to Maria-Helena Semedo of the UN’s Food and Agriculture Organization. Without topsoil, the earth’s ability to filter water, absorb carbon, and feed people plunges.

What is the most important part of the food system?

The world grows 95% of its food in the uppermost layer of soil, making topsoil one of the most important components of our food system. But thanks to conventional farming practices, nearly half of the most productive soil has disappeared in the world in the last 150 years, threatening crop yields and contributing to nutrient pollution, dead zones and erosion. In the US alone, soil on cropland is eroding 10 times faster than it can be replenished.

Why did Brian and Brian start no-till farming?

He and his brother, Brian, began the practice of no-till on their 2,100-acre corn and soybean farm when they learned it could increase the carbon, nutrients and water available in the soil. Their farm is in a particularly dry area of the country, and keeping moisture on their land is a top priority.

When did the Berns brothers start their own cover crop company?

When they first decided to plant cover crops, they had trouble finding seeds. Seeing a hole in the market, they began their own cover crop seed company in 2009, putting together what farmers now call a cover crop cocktail to sow in the fall.

Why is clay important for soil?

Soils that have a higher percentage of clay will have a lower hydraulic conductivity and a high water holding capacity. Sometimes when there is a compacted layer of clay underground it can lead to flooding after heavy storms. Water does not have anywhere to go in such a short time, so its level goes higher and eventually floods our plants. Moreover a higher percentage of clay and silt in the soil will increase the cation exchange capacity. It is an ability of the soil to hold positively charged nutrients called cations (calcium, magnesium, potassium and ammonium–N).

What are the nutrients in soil called?

It is an ability of the soil to hold positively charged nutrients called cations (calcium, magnesium, potassium and ammonium–N). On our planet we have 12 different soil types known as orders. Each one of them needs a different treatment and farmers should know about these practices.

A very useful tool to verify a given soil texture is the soil textural triangle that you can see on the right. It shows you what kind of soil you are working on by taking into consideration the soil’s components.

How to improve sandy soil?

There are different solutions to enhance sandy soil performance. One of them is to add more of the organic matter content.

Why is conservation agriculture important?

Conservation agriculture provides us with the means to protect the land and to work towards the rebuilding of degraded soils. Minimum disturbance of the soil and the establishment of a cover on the surface ( Photo 5) and later, a permanent cover of the soil is an answer to protect our land against topsoil losses.

What are the conditions of tillage?

Traditionally, the majority of soils in our country were ploughed (mouldboard plough) and in many cases disc ploughs were used to pulverise soils even more harshly. These rigorous tillage practices leave the soil bare without cover. Bare soils ( Photo 4) are vulnerable and prone to conditions such as: 1 Erosion following uncontrolled runoff water. 2 Water losses from the soil surface, through evaporation, due to direct radiation and heat from the sun. 3 Increased surface sealing due to the direct impact of raindrops during rainstorms which are common in many areas of South Africa. 4 Beneficial micro-organisms are harmed due to the exposure to direct sunlight and heat.

What is crop rotation?

Crop rotation was already mentioned in Roman literature, and referred to by great civilizations in Africa and Asia. From the end of the Middle Ages farmers in Europe for centuries used a three-year rotation, with rye or winter wheat followed by spring oats or barley, then letting the soil rest (fallow) during the third stage. The fact that suitable rotations made it possible to restore or to maintain a productive soil has long been recognized by planting spring crops for livestock in place of grains for human consumption.

Why did farmers plant profitable crops in the 1930s?

So, when economic pressures came full-on in the 1930s, farmers planted profitable crops repeatedly, rather than rotating the crops. There was just too much need for some predictable income. They needed a cash crop. In the short term this may have helped farmers, but ultimately this practice stripped the topsoil of nutritive value.
