The invention relates to methods of protecting the environment from pollution, and in particular to methods of obtaining fertilizing for vegetable and flower crops grown in sheltered and open ground, and can be used in agriculture. The aim of the invention is to improve environmental protection and the use of solid waste to obtain high-quality nutrition for plants. In the method of obtaining plant nutrition based on liquid complex fertilizers containing nitrogen and phosphorus, followed by the addition of an organic component, according to the invention, humic acid of municipal solid waste and a fraction separated by a 1.0 - 2.5% aqueous solution are used as an organic component caustic potassium in an amount of 0.2 - 0.8% by weight of top dressing. These ratios provide the largest number of active functional groups in the solution and, therefore, tomato seedlings have the best biometric indicators, which ultimately leads to improved yield. |
