- quickly dissolves in the soil – the product does not harm plants and microorganisms;
- stimulation of growth and development of cultivated plants;
- reduction in the number of pathologies;
- resistance of active components to leaching and ease of absorption by cultures;
- environmental safety;
- cost-effectiveness and ease of use;
- an increase in the number of microorganisms in the soil – the soil does not dry out and does not form lumps;
- the possibility of planting plants even a year after applying the product.
Operating principle and purpose
The "Ispolin" preparation consists of 75-80% peat and vermicompost. These natural substances form an organic base, further enriched with humic acids and micro- and macroelements.
"Ispolin" is recommended for use in the following cases:
- seasonal fertilization of all perennials – fruit, ornamental, vegetable plants;
- adding to the holes for planting seedlings and potato tubers;
- adding to holes for planting trees and shrubs;
- preparing the soil for planting annuals;
- soil enrichment for indoor flowers and container plants;
- improving the structure of heavy clay soil or sandy soil with minimal humus content.
Terms of Use
Gardeners most often use a universal fertilizer. This fertilizer has more application options than others. It can be used on any plant, regardless of the time of year. The following options are available:
- Spring soil preparation. In this case, the granules should be distributed over the dug-up soil. It is recommended to use 150 grams of the product per square meter. The product should be incorporated with a rake or a flat-bed cultivator. This can be done during spring soil cultivation or before planting seeds.
- Filling the holes for planting seedlings. It is recommended to apply 15-30 grams of granules per hole and mix them with the soil. The plants then need to be watered and mulched. "Ispolin" is used in a similar way when planting potato tubers.
- Filling tree and shrub planting holes. The granules should be mixed with the prepared soil. It is recommended to use 200 grams of the substance per bush and 300 grams per tree.
- Spring feeding of fruit trees and berry bushes. It is recommended to apply granules of the substance to a depth of 8 centimeters around the tree trunk. Afterward, the plants should be thoroughly watered and covered with a layer of mulch. It is recommended to apply 100 grams of the substance per square meter. Strawberries and wild strawberries are fed in a similar manner.
- Summer plant feeding. To do this, prepare a solution of 50 grams of the product and 10 liters of water. Mix the mixture thoroughly and let it steep for 24 hours. Water the plants with the resulting solution, once a week.
- Autumn soil restoration of garden beds. In this case, the granules should be distributed over the dug soil. One liter of the substance is required per square meter. It should be incorporated into the soil structure to a depth of 8-20 centimeters. This is best done with a rake or a flat-bed cultivator.
"Ispolin Universal" can usually replace other varieties of this product. However, for fertilizing trees and shrubs, it's better to purchase "Ispolin Autumn" separately. This product contains more potassium and phosphorus.
Safety precautions
Although the product is made of natural ingredients, certain safety precautions should be followed when using it. Protective gloves are required when handling the product. Do not eat, drink, or smoke while treating crops. After finishing work, wash your face and hands with soap and wash your clothes.
Is compatibility possible?
When using this substance, you can do without additional fertilizers. However, when growing crops in poor and poorly structured soil, foliar application is still recommended. However, combining Ispolin with mineral substances is not recommended, as this can lead to oversaturation of the soil with salts.
Analogues
The drug can be replaced with such products as "Universal" or "Salut".
Ispolin is an effective substance that positively affects soil composition and improves crop growth. To ensure the product produces the desired results, it is important to strictly follow the instructions. Adherence to safety regulations is also crucial.
