Preparation landing pits grower must pay special attention.

as organic fertilizer for refueling in the pits and trenches fit well decomposed (rotted) manure and various composts in an amount of 15-30 kg per 1 pit (or 1 running. M trench).On heavy clay soils is desirable supplement coarse sand (2-5 buckets per 1 m 2), and in the sandy soils around the same amount of clay.Of the mineral fertilizers on 1 planting hole should be introduced: for pome and stone fruit species - 400-800 g of lime (depending on the acidity of the soil) and from 500 g to 1 kg of wood ash, 200 g aiphosphate fertilizers and 60 g aipotash (Table.).

doses of pre-fertilization of fruit and berry crops (for soils moderate mobile phosphorus and exchange potassium)

berry bushes preplant fertilizer is required in the following amounts: 8-10 kg of organic fertilizer per 1 rm.m, 20 g a.i.phosphate and 15 g a.i.potash for black currant, but for red currants, raspberries, gooseberries and aronia ratio of these elements should be: 15 g aiphosphate and 20 g a.i.potash (as they are "kalilyubivymi").

The fertilizer should be mixed thoroughly with the entire volume of the soil, which fill the planting hole (trench).When planting directly to the roots of plants is necessary to pour the fertile soil without fertilizer.

If planting is done immediately after digging holes, then filling the pits with prepared soil must not forget it lightly compacted (feet), so that there was not much sedimentation (especially after watering).

underlying layers of soil excavated from the landing pit, it is necessary to distribute the top (after landing) on ​​the tree trunks.

When planting fruit and berry plants can make organic fertilizer in the planting hole two ways.In the first case the organic fertilizer well decomposed, they are mixed with the entire soil, intended for filling the landing pit.In the second case, the poor quality of organic fertilizers (poorly decomposed manure of straw, immature compost) them in the landing pit do not contribute, and are used for mulching around-trunk circle in the first or second year after planting.Do it because organic fertilizers low degree of decomposition, getting to the bottom of the landing pit, with a lack of oxygen in the air badly decomposed, releasing ammonia, hydrogen sulfide, which poison the roots of plants.

Peat is used as a fertilizer should not be in pure form.It can only be used for mulching the soil surface under the plants.The best way to prepare for the peat into the soil - its composting with manure, liquid manure, poultry manure, plant and household waste.

phosphate and potash fertilizers, in both cases is made in the lower third of pit Stir with a small amount of soil.Nitrogen in the landing pit do not contribute, as it worsens the survival rate of plants.Therefore, nitrogen and nitrogen-containing complex fertilizers (nitrophosphate, NPK, ammophos, potassium, calcium or sodium nitrate) should not be used during landing.Due to the deterioration of the conditions of rooting is not necessary to give nitrogen and immediately after landing.Nitrogen can be made only after the acclimation of plants: if the landing was carried out in autumn, then do it in the spring;if the spring, then after 2-3 weeks thereafter.Nitrogen is better to make the well to a depth of 25 cm at the edges of the landing pit.

On sandy soils to reduce the permeability planting hole when packing interbedded with compost or lowland peat (layer 3-5 cm) every 15-20 cm with sealing layers.Phosphate and potash fertilizers are applied in this case in those layers, which alternate with compost or peat.Good use of magnesium-potassium fertilizers.

No fertilizer is not applied at planting strawberries, as it does not react to the increased concentration of salts in the soil.The best time to refuel the soil under it - fertilization under the predecessor or the steam station for 2-3 months before planting strawberries.
