Grapes can grow and give the harvest in one section of about 25-30 years, and sometimes 40 or more, taking away from the earth and all the minerals useful components. That’s what you need to correct fertilizer for grapes, so that it can constantly feed the earth with the required amount of minerals.
The main components of the growing plants are called nitrogen, phosphorus, potassium, calcium, iron, magnesium, manganese, zinc, boron, copper, and this is not a complete list of microelements. With their lack of badly grows and brings a meager harvest.
Feeding divided into organic – manure, poultry manure, compost, peat and mineral – ammonium nitrate, urea, phosphate rock, superphosphate, potassium salt.
By planting young seedlings in soil fertilized, they nourish the plant vitamins, necessary in the initial stage of growth. Separate the main period for the introduction of beneficial vitamins, as they are made and fertilizer – root, foliar. The main purpose of both the first and the second stage, to provide the necessary plant nutrients necessary in a given period. Main time use of nutrients is in the fall when the leaves opal or early spring.
First, forming deep grooves 35-45 cm between rows or near the plant itself. The depth of the grooves will allow agents to fall directly into the root system and supply it with the necessary vitamins. In the autumn, before the soil to make vitamins, first they prepare to grapes could all learn – it is manure, compost, peat, phosphate and potash components that are poorly absorbed.
Scientific organizations, by conducting tests based on climate and soil properties, characteristics of culture, defined doses. Manure is applied to the soil again at 3-5 years at the rate of 20-60 tons per 1 ha plot. Standards mineral components depend on the intensity of bush growth, the composition of the soil, cultivar and precipitation on the territory. Often give mineral per 1 ha 90-100 kg of active substance – nitrogen, potassium, phosphorus. Sometimes, the amount of the substance may be 120-150 kg. Those gardeners engaged in viticulture and horticulture associations in their own gardens or near the house, planting a bush spend 2-3 fertilization. They are bred in a given liquid or flowing state, but then further watered soil water.
In early summer, the dressing consists of a single nitrogen, then with the second half of the nitrogen and phosphorus, and at the end of summer – phosphorus and potassium. Alternating application of nutrients you will accelerate the growth of germs, and start up a rich harvest in the current year. The following year, again carried out two or three feeding. But this time, adding manure is better to combine it with chemical fertilizers. In autumn let’s half less than last year. In the third year of 200 grams of superphosphate and 100 g of ammonium sulfate is made for each seedling, digging the groove depth of 35-40 cm. After fertilizer carefully pour water grapes. Enough high-quality crop can be obtained by using the method of making socket – on both sides of the germ pull back 30-35 cm, dig pits 35-40 cm deep and to pour fertilizer and dig.
If you do not want to shed their ovaries, 8-10 days before flowering or as much after, you should feed minerals to significantly improve the effective fruiting.
The third feeding is carried out before the formation of the vines. If, during the first and the next dose you give 30-50 g of superphosphate per bush, 25-30 g of ammonium acid potassium salt and 15-20, during the third – only give phosphorus and potassium in the same doses. Dry fertilizer divorce so that one bush grapes received five liters of solution. If the soil is moist and does not require additional watering enough to dry dressing, it does not only consist of mineral components, but also includes the organics, before this natural mix in water, but that it was two to three times more fertilizer.
The next step – for each bucket of fertilizer give 3-5 buckets of water, and after watering vines. three times a year before digging earth manure or compost are added by 5-10 kg per square meter and add 40-50 g 10-15 g superphosphate and potassium salt per square meter, if desired. In addition to feeding the root, perform spraying grapes of Bordeaux mixture.
