Prospects in landless agriculture

agriculture without land

As the need to grow crops and cultivate agriculture to meet market demand is increasing, the dependence of people on land becomes a pressure on the environment. Because of the increased demand for fertilizer and the need to protect crops from weeds, pests and other factors during cultivation. To solve this problem, there is a big question for the landless agriculture option.

The pressure of traditional agriculture, land-based agriculture on farming and the environment

To meet the needs of farmers, agrochemical products (chemical fertilizers, pesticides, pesticides, etc.) have been widely produced and used. The increased costs of farming with the effects of climate change negatively impact agriculture, as well as the environment.

The birth of landless agriculture.

The challenges facing the soil-based agriculture industry led to the invention of landless agriculture. Hydroponics or other growing media are methods of growing without the use of soil. In soilless agriculture, crops are grown in nutrient solutions (hydroponics) or grown on other types of media but not on the ground (planting on media). Plants will be grown in greenhouses, net houses or in the field without using the earth’s crust (soil). The method of growing plants without soil can be grown indoors or in greenhouses and greenhouses to help reduce the risk of pests and diseases and the effects of erratic weather conditions.

Regardless of the method of planting, all plants need essential nutrients to grow, develop, and bear fruit. Plants require a medium to grow their roots and absorb nutrients in order to grow. It can be soil, or other growing material, as long as the material provides adequate nutrients for the plant to absorb through the roots and must be aerated for the roots to breathe.

Developing agriculture without land

Soilless agriculture is a method of growing plants in media (environment) such as: water (hydroponics) or using single or mixed materials such as coir, husk, light gravel and a variety of materials. other materials to suit each type of plant.

Agri will introduce you to 2 farming methods applied today:

  • Hydroponic method
  • Method of growing plants with substrates (do not plant trees on the ground)

Hydroponic method

Hydroponics is a method of using water containing minerals to grow plants. The composition of these minerals depends on the crop being cultivated. Ideally, mineral solutions contain essential cations and anions, namely magnesium, calcium, potassium, sulfates and nitrates.

There are many different hydroponic methods such as: static hydroponics, reflux hydroponics, aeroponics, etc. Besides, there are many types of media to choose from such as coir, perlite, bark, fired clay, etc.

Method of growing plants with substrates (do not plant trees directly on the ground)

This method is often used in greenhouses, net houses or applied to home gardens, on terraces. This method is often combined with an economical smart irrigation system, mainly the drip irrigation method. Depending on the type of crop and different growing environmental conditions, the price is adjusted accordingly. The substrate should be porous, breathable and rich in nutrients. Agri will give you some of the media used today:

The price of growing vegetables in the home garden

Raw materials for making vegetable growing media at home are usually: cow manure, fresh rice husk, coconut fiber, Trichoderma mushroom, agricultural lime, oil cake. Varieties must be composted or treated before planting. Composted cow manure, rice husk, coconut fiber mixed together to form “soil” for growing vegetables will have high nutrition, cheaper than purchased land and especially light weight. , fruit trees climbing 10-12cm (pots for pots, squash from 150l are suitable). During the growing process, water with fish manure or oil cakes, banana juice or compost from kitchen leftovers.

Growing media for production and business in greenhouses, net houses or greenhouses

For growing plants in greenhouses, greenhouses or greenhouses for production business, they must be tested and have thorough results from specialized agencies. From there, the farmer or farm applies it on his or her garden to achieve good results, good crop growth, high yield, and high product quality.

Depending on the type of plant, the media used is different, based on professional knowledge and experience, the grower chooses the right medium for the type of crop. Plants are grown in pots, on beds or in planting troughs.

Media used for growing cantaloupe in greenhouses

Growing bag of coco coir growing bag for bell peppers

The substrate used is coco peat mixed with organic fertilizers (vermicompost, decayed organic fertilizer, …) with the rate of 70% coco peat + 20% organic fertilizer + 10% rice husk ash. Coir peat, before planting need to handle tannin. The substrate must ensure cleanliness (not infected with pests, microorganisms, weeds), ventilation, not tightly pressed and at the same time provide nutrients for the plant.

Use a 2-layer planter bag (black inside, white outside), size 18x36cm. The medium consists of 70% coco peat (soaked and drained continuously for 7-10 days), 10% smoked rice husks (pumped, drained), 20% vermicompost. Mix the mixture and put it in a bag.

Advantages of agriculture without land

Reducing environmental pollution by not using harmful chemicals to increase crop yield and spraying pesticides to kill weeds and pests in the field.

Soilless farming is the ideal solution in urban areas where space is too limited for gardens.

Yields from landless farming are significantly higher as a result of intensive farming practices and the ability to produce continuously year-round.

The product is safe for users, increasing the use value per unit area.

Fertilizer is provided in the right proportion and is carried through the irrigation system to help plants easily absorb. Increase the efficiency of fertilizer use.

To create products that are safe and highly reliable for consumers. Helps to increase market penetration, increase competitive efficiency.

The method of farming without soil brings high efficiency, the crop is less susceptible to pests and diseases, the yield increases, the quality of agricultural products increases. At the same time, reduce the negative impact on the environment and limit the use of environmentally unfriendly fertilizers. However, this method has a high investment cost and requires a high level of expertise to implement. But this method sets a new expectation for farmers, as well as for the country’s agriculture.
