What are the advantages and disadvantages of hydroponics compared with traditional agriculture?

Hydroponics, referred to as hydroponics, is a technique of soilless cultivation of plants. The word "hydrosponics" comes from two Greek roots: "hydro" (meaning water) and "ponos", the latter meaning work. So we can understand "hydroponics" as "cooperation with water".

Like humans, plants need nutrition to grow. This nutrient can come from soil, be absorbed by plant roots, and be transported to other parts. For centuries, scientists have thought that soil is the basic element of plant growth, but in fact, soil can be easily replaced by the total amount of water management. This nutrient solution, also called hydroponic solution, contains all the nutrients needed for plant growth.

How to realize hydroponics at home?

Making hydroponic solution

First of all, we need to make nutrient solution that can replace soil. Simply put, aqueous solution is an important nutrient and mineral for water and plant growth, and the most basic nutrient medium must contain elements such as nitrogen, phosphorus, potassium, calcium, magnesium and sulfur.

Most hydroponic solutions with appropriate proportions are easily available in the market. There are also many books detailing the chemicals needed to make hydroponic solutions and their dosage. However, if you prefer the "natural" way, here are some natural ingredients that can be used.

Gypsum, lime, bone meal and eggshell are rich in calcium, banana peel is rich in potassium, baker's yeast is rich in phosphorus, and soybeans and lentils can provide nitrogen. However, be careful when using it to prepare marine police solution. Because it has not been carefully measured and verified, it may take many attempts to get the desired results.

The general idea of hydroponics is to fix plants on some columns and hang their roots in the hydroponic solution below, so as to provide continuous nutrition for plants. So if you want to be a bathtub farmer, you need more than just a bathtub. Fix the net on the edge of the bathtub, put the plants on it and pour the marine police solution into the bathtub.

You can take the pipe, open a round hole in it, put the root of the plant in the hole and let it hang in the bathtub below. If the plant is too small, you can gently take root with nylon rope and let the nutrient-rich water flow up slowly.

In short, what you need to do is to ensure the nutritional balance of the hydroponic solution, and then soak the roots of plants to get enough light.

First of all, hydroponics is not that troublesome. If you like growing plants, but don't like digging them out of the soil, or are afraid of all kinds of bugs crawling on you, then a marine police will be the best choice.

Plants can get enough water and nutrition from the marine police system without spending too much energy to develop complex roots, so they can provide fresher and healthier plant products in a shorter time and have higher output. After comparing hydroponics with traditional farming methods, scientists found that the yield of plants grown electronically increased by 17%. In another study, a cultivated potato can harvest 75 stems, but the yield of soil cultivation is only 3 to 5. The hydroponic potato is also 5 1% larger than the potted potato. Hydroponics can also be carried out in places where traditional farming is not possible. In addition, hydroponics increases the green area of living space. The water and fertilizer required by this method are 10% and 25% of soil agriculture, respectively, and the operation cost is low. We can grow fresh vegetables and fruits with little investment and without much experience.
