Having provided a good harvest, the land is depleted, losing most of its nutrients, so with the onset of autumn it is very important to saturate it with missing trace elements, thereby increasing the fertility and your chances of getting a good harvest next season. What fertilizers to make under the dig in autumn - in this article.
Nitrogenous fertilizers
Nitrogen in the soil plays a huge role, because it increases the amount of protein, thereby enhancing the development and growth of culture.
The following applies to nitrogenous fertilizers:
- Horse litter . This organic top dressing with a dense consistency keeps nitrogen in the soil throughout the season, decomposing over the winter and enriching it with the necessary trace elements. It can be used both fresh and re-baked at a rate of 3 kg per m². The frequency of application depends on the fertility of the soil and is 1 time in 1-2 years.
- Bird droppings . Excellent organic top dressing, improving the quality of the soil. On 1 m² of soil, 2 kg of fertilizer is applied once in 2-3 years.
- Mullein. Those who are interested in what fertilizer to make in the autumn under the digging, it is worth paying attention to this organic, which in fresh form is applied only at the end of the season. In this case, the mullein is made to mix with the ground, so that there is no open contact with the air, as this can lead to the evaporation of a large part of the nitrogen. Apply from the calculation of 6 kg per 1 m² and smell.
- Mineral fertilizers - urea, ammonium sulfate, sodium nitrate, ammonia water. A granulated mixture of fertilizer called urea is introduced under the dig in autumn at a rate of 15 g per m². Top with earth. When using mineral fertilizers, you must strictly follow the instructions, otherwise you can get the opposite effect and slow the development of planting.
Potash fertilizers
Potassium takes part in carbon and protein metabolism, is responsible for the quality and volume of the crop.
Potash fertilizers include:
- The ash . This is an organic bait, which is obtained by burning weeds, foliage, etc. It is advisable to use it on clay and heavy soils at the rate of 1-2 glasses per 1 m 2 with a frequency of every 2-3 years. Soil repetition is mandatory.
- Mineral fertilizers - potassium sulfate, potassium chloride, cainite, calimagnesium . Most often potassium chloride is used at a rate of 15-20 g per 1 m². The norm of the remaining funds can be increased by 1.5-2 times. Work with such compounds is carried out in protection - a respirator, gloves and glasses.
Phosphate fertilizers
This element normalizes the water balance, is responsible for the proper development of plants, increases the quality of the crop, accumulates enzymes and vitamins.
Phosphoric fertilizers include:
- Bone meal . The introduction of this fertilizer in the autumn under a digging provides its distribution on the surface of the earth at the rate of 200 g per 1 m².
- Compost , consisting of feather grass, wormwood, hawthorn, mountain ash, thyme.
- Mineral fertilizers - superphosphate, double superphosphate, precipitate . Those who are interested in what mineral fertilizers to make in the autumn under a digging, it is worth noting that superphosphate is scattered at the rate of 50 g per 1 m². It is often combined with nitrogen preparations. The other two are combined with potash to improve the cleavage of phosphorus.
Other types of fertilizers
From other fertilizers for autumn digging can be identified sawdust. They loosen heavy soil and create the prerequisites for the development of various microorganisms, earthworms. At the end of the season in the form of compost is introduced and peat. In addition to it, manure, ash, weeds of weeds, etc. are present in the mixture. Peat is dumped with a thick layer at a rate of 4 kg per 1 m 2 and is smelted into the ground.
