Soilless cultivation is an innovative process that was introduced in recent years for protected crops. This practice has been established for the large-scale production of fresh vegetables and ornamental plants, especially in the countries of Northern Europe, with the main purposes of:- Increasing production- Optimizing acreage - Reducing working times- Reducing the need for water and fertilizers - Optimizing climatic conditionsThe continuous climate changes, the increasing interest in environmental impacts, and the availability of cheap facilities and simple technologies all lead to an increased use of soilless cultivation in commercial applications. When talking about soilless crops, we’re referring to two types of systems:- Real hydroponics, without substrate: the root system of a plant is directly in contact with the water and the nutrient solution (floating system, nutrient film technique, aeroponics)- Hydroponics with substrate: the plant grows on inert, organic materials, or a mixture between them (cultivation bags, slabs, pots or bins)In these systems, fertigation feeds the plants and involves the use of water-soluble fertilizers. In the most sophisticated and technological systems, the nutrient solution is recycled continuously, thus ensuring maximum efficiency of the water resources used (closed cycle). In the simplest systems, however, especially in those based on the use of the substrate, the drained nutrient solution is dispersed (open cycle)...

This article is part of a series on biological control and Integrated Pest Management written by UAV-IQ (www. uaviq. com). In agriculture, input distribution companies are essential stakeholders for their role as intermediaries between manufacturers of new products and growers. Their research programs and continuous education to growers are also important, to make sure the products are used properly as part of tested protocols...

In the previous article in this series we discussed classical biocontrol, which is the practice of identifying the origins of pests found in local fields, then finding the natural enemies of those pests in their foreign origins and bringing the “enemy of my enemy” (otherwise known as “beneficials”) back from their homelands to local farms to renew old rivalries and help suppress pest populations. As we have seen, this strategy is usually coordinated, or at least regulated, by public organizations at a regional, national or even continental scale. But a lot of the pests damaging our crops are actually native to our regions and already have local natural enemies. The problem though is that the population of those control agents is often insufficient and on the decline, for various reasons, some of which we will discuss in an upcoming article. To highlight a few of the most common causes though, industrial farming techniques such as monocropping and the use of phytosanitary products can affect populations of beneficial insects...

Seaweed fertilizer is an organic fertilizer produced by accurate processing of marine plant seaweed as the primary raw material. The main component is the natural organic active material extracted from kelp. Below are the advantages of seaweed fertilizer for plants:1 Nutrient-richThe active seaweed fertilizer contains a large amount of non-nitrogen-containing organic matter, including 40 kinds of minerals such as potassium, calcium, magnesium, iron, zinc, and iodine, and abundant vitamins, which are unmatched by terrestrial plants, especially seaweed polysaccharides unique to seaweeds. Alginic acid, highly unsaturated fatty acids and a variety of natural plant growth regulators can stimulate the production of non-specific active factors in plants and regulate the balance of endogenous elements. 2 Easily absorbed by plantsThe active ingredients in seaweed fertilizers are particularly active after they have been specially treated, and they enter the plants within 2 to 3 hours after application, and they have a speedy absorption and conduction velocity...
