In the sphere of amateur gardening and truck farming the onions are considered to be very unpretentious vegetable culture capable to yield rich harvest without application of special agrotechnical receptions. However it is necessary to know that the timely, competently carried out fertilizing of onions is capable to almost double its productivity.
Onions, as well as any other vegetable culture, need regular watering, ensuring with enough heat and light, protection against wreckers, thorough weeding and fertilizing with fertilizers. Thinking of that, as well as than to feed up onions to grow up the large, dense and long stored in the winter fruits, it is important to follow the certain schemes various for organic and mineral fertilizers.
Fertilizing of onions minerals
Traditionally fertilizing by mineral fertilizers provides three phases:
- stage of forming of abundant greens (feather). At this time the best result is yielded by nitrogen fertilizers: carbamide, chloride potassium, etc.;
- stage of formation of bulb. Fertilizers with the content of potassium and phosphorus are preferable: monophosphate of potassium, nitroammofosk, nitrophoska;
- period of forming and maximum growth of bulb. At this stage i.e. when the bulb has about 3-4 cm diameter, the good results are yielded by fertilizer superphosphate. If cultivation of this vegetable culture is carried out on fertile soils, then the fertilizing containing phosphoric components can be missed.
As a rule, organic fertilizers are subject to dissolution in water in proportion, the corresponding instruction from the producer then solution is carefully brought in the soil, avoiding its hit on land parts of plant. In rainy summer also use of such way is allowed: the granulated fertilizers accurately scatter on the surface of the soil at distance 5-8 cm from bed with onions. After small moistening by rain water of granule close up in soil on depth about 6-10 cm.
Fertilizing of onions organic chemistry
Before feeding up onions the structures including manure of farm animals, bird's dung, compost and other organic components it is necessary to make sure that for fertilizer the fresh concentrated manure capable to cause various diseases of plant is not used or to affect negatively forming and growth of bulb. It is also important to pay attention to concentration of nutritious solutions – the excess of fertilizers will direct plant forces to growth of abundant greens therefore bulbs will remain immature.
It is very useful to apply the grass which has remained after weeding of kitchen garden to fertilizing of onions. Weeds place under press in the big container with water and leave for 2-3 days for insisting. Then the glass of grass infusion is added to bucket with water and use this solution for onions fertilizer. The only lack of similar organic fertilizing is that together with fertilizer on beds seeds of weeds can get.
Other types of fertilizing of onions
Besides traditional organic and mineral fertilizers the amateur gardeners often use such means as baking yeast stimulating growth and the diluted ammonia solution.
As a rule, about deficiency of nitrogen in the soil the turning yellow onions feathers signal. In that case it is possible to correct situation by means of 3 tablespoons of the ammonia solution divorced in 10 liters of water. Fertilizing is made by watering of the soil in the evening. If by negligence of drop of solution have got on green parts of plant, then subsequently beds need to be spilled carefully from watering can warm water to wash away residues of fertilizer from onions.
This method is popular not only thanks to usability, but also due to ensuring additional protection of plant against such annoying wrecker as onions fly.
Barmy fertilizing promotes stimulation of growth of underground part of plant, but the fact that for yeast the warm environment, i.e. well heated-up soil is necessary for full functioning is considered lack of this type of fertilizer.
As fertilizer both the instant, and pressed yeast which parts in 5 liters of warm water with addition of 5 tablespoons of granulated sugar and 2 glasses of ashes can be used. Solution is infused within hour then use for radical fertilizing.
