![Hydroponics Yield [Do Plants Grow Better in Hydroponics or Soil?]](https://uponics.com/wp-content/uploads/2017/12/lettuce-139602_1920-e1514487379992.jpg)
Hydroponics is a system that uses water instead of soil as the plant’s growing medium. The roots do not come into direct contact with the soil but are immersed in a nutrient solution. Hydroponic systems can be categorized by their root-zone media, such as rockwool, perlite, vermiculite and sand. Another system uses no media at all — just bare roots dangling in the water.
Hydroponics yield has more nutrients than soil-grown plants because the plant roots are exposed to oxygen and the nutrient solution. In soil, the roots are surrounded by air, but they are also surrounded by soil particles which absorb water and nutrients. Thus, the plant cannot access all of the nutrients in the soil. In hydroponics, this is not a problem because there are no soil particles surrounding the roots.
The other reason for increased nutrient availability is that hydroponic systems can deliver nutrients to plants at very precise rates and amounts. Soil-grown plants do not have that luxury; they must take whatever nutrients they can get from their environment.
The hydroponics yield has more nutrients because there are no pesticides in the plants. Hydroponics is a method of growing plants without using soil. The plants are placed in water or nutrient solution, their roots suspended in the liquid.
In soil, pesticides and other chemicals can leach into the plant tissues. Since hydroponic systems do not use soil, there are no pesticides or other chemicals in the plant tissue to leach out. The only substances that enter the plant are those taken up from the water or nutrient solution.
In addition to this, when you harvest a plant grown in soil, you get a lot of extra stuff in your harvest besides just the fruit/vegetable itself (roots, stems, leaves). In a hydroponic setup, you are only harvesting what you want – there’s nothing left over!
In a hydroponic system, the plants are immersed in a solution of water and nutrients. The nutrient solution provides all the nutrients needed for plant growth.
Some nutrients, such as nitrogen and potassium, are absorbed through the roots and some are absorbed through the leaves. These nutrients cannot be measured directly, but they can be calculated by measuring other elements in the soil or water. You can buy online here.
The concentration of dissolved salts is often used as an indicator of nutrient concentration in irrigation water. For example, if you have 100 ppm of nitrate in your irrigation water, that means there are 100 milligrams of nitrate per liter (ml) of water.
Nutrient concentrations vary with weather conditions, soil type and management practices. Soil samples can be collected from different places around the property to determine the nutrient level where your crop will be grown.
