Potatoes have poorly developed root system, so it needs oxygen.Best air and moisture exchange at it, is quite moist and loose soil.However, long-watering potato leads to waterlogging and destruction of the root system.Therefore, searching for land for planting, the soil is better to choose light, long time to keep the looseness that will not swim after a rainfall, will have a neutral or slightly acid reaction and contain at least 2% of humus.If the soil is hard, it is necessary to add organic fertilizer.A heavily waterlogged soil plant cultivated using ridges or crests to avoid Rhizoctonia and diseases, bacterial wearing character.
Watering
No less important part of the care of the plant is its watering.How often to water the potatoes to prevent it from waterlogged?Once the potatoes are planted and before emergence of the plants are not watered, since in this period he formed root system that is capable of humidity at a comfortable well-branch and penetrate deep into the soil.If the ground waterlogged, the roots will be located on insufficient depth, which subsequently affect the ability of plants to extract moisture and have a negative impact on development.As soon as the first shoots were formed and bushes, the plant begins to consume more water, but overdo the watering is not necessary.The main signal for irrigation is considered dried up the top layer of soil to a depth of 6 cm.It is better to carry out this procedure in the evening to avoid evaporation.Once it is significantly lower leaves wilt - just need to make a watering potatoes.The largest amount of water the plant will need at the time of budding and flowering.It is important to provide him with sufficient moisture to prevent the emergence of young tubers and then dig a vegetable the size of a pea.Dry out tops in the month of August, in times of drought and lack of rainfall.To reduce the temperature of the soil is necessary to perform a watering potatoes, extending this period of vegetation, and thus enhance the yield.
Terms watering
very important question: how to water the potatoes?The first watering per one hundred square meters of land is necessary to ensure normal water is about 300 liters, and the next - about 500 liters.To moisten the soil is better not to use cold, and so-called "summer" water, which is preheated in barrels.
conduct watering potato can be only in the morning or in the evening.Irrigation of the lungs of land needed to produce much more than heavy, it does not prevent the formation of solid crust on the soil and from time to time to loosen the ground.During irrigation under any circumstances can not direct the stream of water directly on potato bush, and it is better to use a spray hose.No need to water the plant before harvest - it can hurt.If you wish, you can make a drip potatoes, which greatly reduces the cost of water, can be combined with fertilizing and long time support the necessary soil moisture.The use of this equipment is very good effect on the crop, but the cost of such installations is fairly high.
