Will Farming Without Soil Help Solve Our Food Crisis?



The world is in the grip of a food crisis. In many parts of the world, fields can no longer be cultivated due to the excessive use of pesticides, droughts and extreme weather events caused by changing climate. Good quality soil is getting scarce for growing crops to feed the sweltering global population. So, is there a way to meal prep without needing to use clay? Several companies are doing just that, using different methods such as growing underwater crops, using nutrient-rich moisture, or repurposing the coffee ground as fertilizer.


There are some well-established methods, such as aeroponics, where plants roots are suspended and sprinkled with nutrient-rich water. The second is the water passage, where fish are also farmed along with the plants, and their waste products are used to nurture the plants. Not only does being able to grow food without the need for soil have implications for growing crops on Earth, but could also prove key to sustaining our survival on the Moon or Mars.


Being able to grow plants without soil will be key to having a reliable food source and helping us sustain a presence on other planets. In this gallery, we bring you some projects that demonstrate that it is possible to grow food in ways that are sustainable and kind to the environment. Appearance farms use modern vertical farming techniques in conjunction with aquaponics, therefore crops are cultivated in a complete ecosystem. Fish swim directly beneath these plants, which absorb nutrients from fish waste.


Plants filter water as soon as they grow, thus water usage decreases by 95 percent. The crops and seafood produced here are exported all over the world. Herbs are growing in the underwater biology of the Namo project, anchored under the sea. The project began in 2012, and now has more than 300 plants grown with an automated hydroponic system. Tulsi is the main herb grown, but experiments are also done with mint and wine.
Circle Food & Energy Solutions has a farm on the outskirts of Room.


Here, in the Italian countryside, with vertical aquaponics systems, this small company grows a variety of edible crops without impacting the environment. Aquatic weapons is a method of growing plants in water, using waste produced by fish and small sea creatures. Plants can extract nutrients from this waste, and, in turn, purify water, so this is a system with almost no waste. The Aquaponics system enables the cultivation of baby leaves and aromatic herbs.


The system is designed to allow water to flow from top to bottom, thus transporting nutrients in plants. The plants then purify the water themselves and leave it in the containers below.

Located inside two shipping containers, the company uses hydroponic technology and nutrient-rich water to grow green vertically in urban environments each year.


Soil disturbance, proper grazing management, restoration of degraded grasslands by limiting the use of suggested fire thought, or planting native species with a deep root system reduces plant productivity and soil carbon losses by limiting soil carbon Increasing the population increases the carbon stock of grasslands. Looking for grass or fruit species in degraded grasslands can improve bottom production, and – in the case of fruits — improve soil fertility by nitrogen-fixing.


Fertilizer and irrigation can have a strong positive impact on plant production and soil carbon stocks, although these practices apply mostly to managed grasslands as well as pastures. These management methods will vary the changes in ecosystem carbon, with the greatest benefits expected to occur in cold humid climates and the least in hot barren climates. Soil carbon recovery is usually a slow process, depending on the system’s carbon balance for decades to centuries.


Despite these slow changes, the global likelihood of carbon compilation from the regeneration of degraded grasslands is significant, equivalent to reducing environmental CO2 by 50 ppm in 50 years with the possibility of segregation of about 3 every year. Besides restoring degraded grass to improve carbon storage, grass field management strategies are crucial to maintain grass field cover and prevent decay to protect this land’s ability to accelerate carbon The purpose should be recognized.


The best management methods for maintaining or restoring carbon in grasslands should, as a minimum, reduce soil stress to improve these soil and water processes. Beneficial methods for carbon management include reducing or shortening the duration of tight soil by planting cover crops at the time of farming  It is important to determine appropriate storage rates for grazing lands to prevent maximum grazing in order to form required species in the soil and to maintain appropriate plant cover and biomass input.
