How can you fertilize strawberries?!

How I wish that all the efforts made in the process of growing strawberries would not be in vain and that the harvest would please the eye not only with its quantity, but also with its quality. To do this, the berry must be properly fertilized, and then the result will delight the soul not only during the period of ripening and harvesting, but also when prepared for the winter. But how to properly fertilize strawberries without any special material, physical and moral costs?!
Initially, shortly before planting, it is necessary to fertilize the soil with manure or legume siderites. Manure is spread at the rate of 40-50 tons per hectare. Manure is applied to the fallow field in autumn or early spring. In the fight against annoying weeds, it is very effective to use herbicides, which greatly facilitate the task.
Just as already mentioned, bean siderites can be used instead of manure. In early spring, a vetch-oat mixture should be planted (150/50 kg per 1 ha, respectively). Before sowing siderites, it is worth adding NPK at the rate of 60 kg per 1 ha. After flowering of this ratio, the resulting green mass must be crushed and pushed into the soil to a depth of literally 15 cm.
During the period of operation of the berries, nitrogen fertilizers should be used in early spring and after harvesting.
You can also fertilize the soil with ammonium nitrate (1.5 c per 1 ha). After the harvest is harvested, it is better to mow all the strawberry leaves at a height of about 6 cm, after which the mowed mass is collected. And of course, don’t forget about regular watering and loosening.
This system for fertilizing tasty berries increases fertility by an average of 35-40% and saves time and costs by literally 2 times.
