Organic and Mineral Fertilizers

Organic and Mineral Fertilizers

No matter how high the soil fertility on your site, its level decreases after each harvest. Fertilizers help prevent this, which compensate for the removal of elements that are of great importance for plant growth. Their effect depends on the composition, degree of solubility, quantitative content and ratio of their constituent components.

What are plant fertilizers?

Depending on the origin, fertilizers are divided into two large groups:

mineral – nutrients (active substance) are contained in them in the form of salts and become available to plants as they dissolve. They are used to quickly replenish soil reserves and balance nutrition. Due to the fact that the composition and content of the active substance in them is known, it is possible to calculate the required dose of application for flowers, vegetables, berry or garden plantings;

organic – represented by products of animal or plant origin, and the elements are released into the soil solution as a result of the decomposition of organic matter by microorganisms. Such fertilizers are characterized by prolonged action and have a beneficial effect on the structure of the soil, its water-air regime, and reserves of organic matter.

In turn, mineral fertilizers include:

  • simple – contain one nutritional element (nitrogen, potash, phosphorus);
  • complex – they contain several elements in a certain proportion.

New complex fertilizers

In recent years, new water-soluble forms of fertilizers with a balanced composition have appeared on the market, which combine the advantages of mineral and organic compounds. At the same time, you can buy them at an affordable price and choose formulations developed not only for vegetables, but also for flowers, gardens, lawns. In particular, these include:

chelated – as a rule, they are used for foliar dressing and contain trace elements in a readily available form that easily penetrate the leaf blade;

fulvates and humates are made on the basis of fulvic or humic acids, which are an integral part of humus. As a result of the enrichment of humates with macro- and microelements, complex complexes are obtained that increase the resistance of cultures to unfavorable factors, stimulate metabolism, and increase cell activity. Being of great importance for growth, they also improve the condition of the root layer, activating the soil microflora;

organo-mineral with a pesticidal effect – in addition to a set of nutrients, they may contain stimulants, amino acids and have a fungicidal effect, protecting plantings from diseases.
