Feeding potatoes when planting in the hole
To get a high-quality and plentiful crop, you need to properly fertilize your plantings. Experienced gardeners believe that if potatoes were fertilized during planting, this not only increases the yield, but also improves the resistance of plants to various diseases. Properly planted potatoes with good top dressing strengthens tubers and forms the desired fruit size. The nutritional requirements for potatoes are very high, therefore, when determining the dosage of fertilizing, one should take into account the direction of use of potatoes, the richness of the soil and the expected level of agricultural technology.
Feeding potatoes when planting in the hole
Successfully growing potatoes will greatly depend on whether you added dung when planting in the hole or not. Manure is not only a source of nutrients, but also improves soil properties. All over the world, any type of manure is the best top dressing when added to the hole. The best time for using manure is autumn and spring. In order for manure not to burn your landings, it is necessary that it first be quail. Some gardeners add manure to the ground in the fall and overwinter during the winter. If it is not possible to introduce manure for such a long time, then it can be prepared several months and weeks before the intended planting. The optimal dose of manure per 1 ha is 25 tons, which brings 125 kg of nitrogen, 75 kg of phosphorus and 150 kg of potassium to the soil.
The main function of manure is to bring organic matter to the soil. In order to have a good harvest, it is necessary to guarantee a sufficient amount of easily digestible nutrients. All this gives you organic fertilizer. The use of manure is an integral element accompanying agricultural processing. As such fertilizer, only well-digested manure can be used. In the first year after making manure, plants can use up to 50% of all its components. Mineralization and decomposition of manure in the soil lasts a long time. Such top dressing ensures the best use of nutrients contained in manure by plants, and thus increases the yield of the number of tubers.
- Owners of living creatures in the private sector will be grateful for the help in processing and can give manure for free.
- Manure almost doubles the yield.
- Manure helps maintain soil moisture, making it soft and oxygenated.
Manure can be used in the autumn before digging the site. The dosage at the rate of 10 liters per 1 sq.m is applied to a depth of not more than 40 cm. A mixture of manure with sawdust is well suited for warming the beds. In order to insulate the beds, the manure is scattered in small lumps in the desired area. Dosage - 1.5 buckets per 1 sq.m.
Please note that when manure is found outdoors, a large amount of nitrogen evaporates.
If you correctly calculate the dosage of fertilizing, then after planting potatoes in the ground, the tubers will only grow stronger over time, since such an element is especially necessary for the development and growth of the plant. Nitrogen dressing should be applied in the spring before planting potatoes in the hole, carefully mixing them with the soil. The uneven distribution of top dressing in the soil can only concentrate around the seed, and this will negatively affect the seeds.
Excessive use of nitrogen affects the lush development of the aerial parts of the plant and delays harvesting. It also contributes to exfoliation of the epidermis, an increase in nitrate content, a greater darkening of the tuber flesh and a decrease in dry matter, starch and vitamin C. In addition, nitrogen increases the susceptibility of tubers to mechanical damage during storage, so it is important not to overdo it with the mineral.
Fertilizer will help the plant grow
- Nitrogen in combination with magnesium and sulfur improves soil quality and stimulates planting growth.
- When used correctly, natural compounds soften water and improve leaf nutrition, which leads to the formation of a layer that impedes the penetration of harmful pathogens.
- Nitrogen is the most powerful nutrient for fertilizing a hole before planting potatoes.
Nitrogen must be introduced into the ground before planting, according to the instructions. Dosage should be calculated based on the number of plantings of seed per square meter. If, after introducing nitrogen into the earth, your plantings did not begin to grow actively, but rather slowed down in growth, this may mean that the dosage is violated. In the case of nitrogen top dressing, it is better not to report nitrogen than to saturate the earth.
If you plan to fertilize potatoes with nitrogen, then it can be supplied with other nutrients - and trace elements. Otherwise, before the flowering period, your plantings may not absorb nitrogen. Unidirectional fertilization of potatoes without supplying other nutrients leads to a decrease in technological quality, large losses during storage of tubers and often higher susceptibility to disease.
Another best potato fertilizer is long-lived urea. In early cultivation, it is recommended to use such top dressing when added to the ground before the flowering period. In addition to other top dressings, potassium is also equally important for the proper functioning of plants. Potassium controls the absorption of nitrates by the roots, which are then transported to the leaves and used to produce protein.
- The photosynthetic activity of the plant increases, which leads to an increase in the content of carbohydrates (starch).
- The content of vitamins in tubers increases (B1, C).
- Fruits become less prone to damage.
Urea is used in combination with other minerals, for example, together with potassium. Top dressing has a positive effect on plant resistance to pests. Plantings that eat well enough in combination with potassium, phosphorus and nitrogen become more resilient and resist viruses and pests. If you add each mineral to the earth at the right dosage and carry out the right care, then your harvest will become plentiful over time.
Wet soil fertilization
Potatoes can be fertilized before or immediately after planting in the hole in case of excessive rainfall, when the pH of the soil is too low or too high, and also when the amount of humus is too small or when important trace elements are missing. Dosage: Urea (10-15 kg n / ha, dissolved in 400-600 liters of water). Depending on the variety, the scarcity of soil and the stage of growth of potatoes, approximately 2-4 treatments are carried out with an interval of 7-10 days.
Some leafy fertilizers used with fungicides increase pest control and reduce recommended doses of fungicides. Such processing can be carried out both when planting in a hole, and after planting potatoes. Processing should be done in the morning at a temperature of 12-15 degrees and high humidity. Such treatments are also effective for several hours after rain, when the plants are dry and soil moisture allows mechanical spraying. It can be noted that on moist soils when planting potatoes in a hole, some fertilizers may not work or they can be washed off by rain.
Please note that if you process plantings at night, the recommended dose of nitrogen and other fertilizers is reduced by 20-30%, without affecting the quality of the tubers. As phosphate fertilizer, triple superphosphate can be recommended. The best potash fertilizers are potassium sulfate and magnesium sulfate, because they contain a small amount of harmful sodium chloride and a significant amount of sulfur and magnesium.
In the absence of these fertilizers, potassium salts should be used. Phosphorus and potash fertilizers should be applied on coarser soils in the fall under plowing, and on light soils in areas with a large amount of rainfall, it is better to use spring standard fertilizers. When growing potatoes, in addition to standard fertilizers, multicomponent top dressing is used both during planting and after it until the flowering period. If you properly fertilize potatoes during planting, then you will receive a plentiful harvest already in the current season.
