Farming is fundamental to any society if its people do not want to spend their days searching for, collecting and hunting food. It is big business and is classed as a primary industry taking its resources from the land.
However, the agricultural industry in this conventional sense suffers from a major disadvantage – soil erosion.
When land is worked through crops or other agricultural processes, it reduces the overall structure of the soil, in addition to reducing the levels of organic matter, making it more susceptible to the effects of rain and water. Tilling in particular, because it often breaks up and softens the structure of soil, can be a major contributor to erosion. Farming practices that reduce this activity tend to have far less issues with soil erosion..
Erosion is the movement of soil by water, wind or gravity. Although this process occurs naturally, industrial farming practices have dramatically increased the speed at which agricultural soils are eroded. Currently, 80% of the world’s agricultural soil is affected by soil erosion resulting in farmers got nothing in exchange for agricultural investment.
The process of soil erosion is made up of three parts:• Detachment: This is when the topsoil is actually “detached” from the rest of the ground. • Movement: This is when the topsoil is relocated to another area. • Deposition: Where the topsoil ends up after this process.
What do we know?• Since wind erosion releases fine dust particles into the air, it poses a potential threat to human health. • The European Union is losing 970 million tonnes of soil per year due to water erosion, an amount equivalent to a one metre-depth loss of soil from an area the size of the city of Berlin or enough to cover an area twice the size of Belgium with one centimetre of soil. • Soils store more than 4000 billion tonnes of carbon
In order for the agricultural industry to become more sustainable, solutions need to be put in place to prevent and control the erosion of soil. There are various solutions which farmers have already started to use. Tillage and cropping practices, as well as land management practices, directly positively affect the overall soil erosion problem and solutions on a farm. When crop rotations or changing tillage practices are not enough to control erosion on a field, a combination of approaches or more extreme measures might be necessary.
Another method which the agricultural industry could consider is to use Commercial Aeroponic farming. Aeroponics does not use any soil or medium and therefore cuts out any risk of contamination or erosion..For information about aeroponic farming contact us today.
